Description

  The present invention relates to an apparatus, a method, and a control program for formulating a plan for periodic inspection performed on each power generation unit.

  In power companies that supply electricity to general households and factories, etc. and large-scale power supply companies, it is legal to perform periodic inspections of power generation units and the equipment that constitutes power generation units within a certain period of time. Is required. The legal requirement is that periodic inspections are performed to prevent breakdowns and accidents within the power generation unit and to ensure a stable power supply function.

  In this periodic inspection (hereinafter abbreviated as “regular inspection”), specifically, the degree of erosion, wear, etc., by disassembling huge devices and parts such as boilers, turbines, and generators that are components of the power generation unit It is necessary to inspect and replace consumable parts.

  However, once the device is disassembled, enormous assembly and confirmation work is required for reassembly, and it is difficult to immediately return the power generation unit to a state in which power can be generated. Usually, the regular inspection of such a power generation unit has a period of about 1 to 2 months at the shortest and about 4 to 6 months at the longest.

  For this reason, when regular inspection is performed in a plurality of power generation units, the power supply capability is remarkably reduced, so that there is a possibility that the power demand cannot be sufficiently met. If the supply cannot catch up with the power demand, for example, a large-scale power outage will occur within the power supply range, and the stable supply of power, which is the most important mission of the power company, will not be achieved. It can have immeasurable effects.

Therefore, the following inventions have been proposed as an operation / maintenance plan support system for each power generation unit with respect to the current power demand (see Patent Documents 1 and 2).
For example, in the present invention, first, the process value of the power generation unit is captured, and the ideal value and the rated value are obtained from the model of each device, thereby detecting the degree of deterioration and the degree of aging of each device from the difference from the actual data. . Then, referring to the degree of deterioration and aging of each device, determine the economic effectiveness of the replacement and repair, such as whether to stop the power generation unit or drive it until the next regular inspection. Develop a plan.

In particular, this maintenance plan is a method of allocating the load of each power generation unit with respect to the current demand, a method of operating so as to extend the pre-life until the next regular inspection, and a method of determining whether to immediately inspect and replace parts. Etc.

  By the way, when formulating a regular inspection plan for the power generation unit, it is necessary to confirm that the total power supply capacity in the power pipe managed by the power company satisfies the demand forecast. If the demand forecast is not met, or if there is no fixed reserve rate (margin) for the demand forecast, it is necessary to transfer or defer the regular inspection process of some power generation units to another Occurs.

  Here, in order to formulate a regular inspection plan, as described above, a predetermined inspection interval is legally required, and a power generation unit that can be moved or deferred and a power generation unit that cannot be deferred. Exists. For this reason, regular inspections are performed for power generation units that cannot be moved, but even if there are other power generation units that actually require regular inspections, regular inspections must be canceled instead. Therefore, each power generation unit rarely has the same type of equipment, and the amount of electric power that can be generated is different. Therefore, it is necessary to calculate the accumulation of the total power supply amount again.

  In addition, electricity demand grows at a certain rate of growth every year, and is also affected by the seasons, and also changes greatly between holidays and weekdays. Must be considered. In particular, in general, since the maximum load of power demand (hereinafter abbreviated as peak load) arrives around 13:00 to 15:00 in the day, check whether it is possible to cope with this peak load sufficiently. Is also required.

  However, such calculation of power demand cannot be performed by a human system, and in the past, it was supported by planning with a certain amount of margin or by considering the reserve rate from past experience. These were not accurate demand forecasts.

  In addition, although the operation / maintenance plan support system for each power generation unit as in Patent Documents 1 and 2 shown above has been proposed, the present invention is intended to devise a maintenance plan based on the current process amount. Yes, it does not take into account future power demand. In particular, no consideration has been given to how power generation units are allocated to future demand, and no future demand prediction is performed in the first place.

  Further, according to the present invention, the period and schedule of the regular inspection are already determined in a predetermined database, and the information is simply input when used, and the plan itself is a plan that satisfies the demand. Does not have a function to evaluate whether or not. That is, no consideration has been given to whether the power supply is a plan that satisfies future demand or whether the plan is to secure a predetermined reserve ratio.

  The present invention has been proposed to solve the above-described problems, and its purpose is to perform demand prediction over the next several years, and to operate the power generation unit in a pseudo manner with respect to the demand. To provide a periodic inspection plan development device, method, and control program thereof capable of developing a regular inspection plan for each power generation unit based on accurate demand prediction and supply capacity by verifying whether the allocation and supply capacity are satisfied It is in. It is another object of the present invention to provide a periodic inspection plan formulation apparatus, method, and control program therefor that can formulate a periodic inspection plan after performing accurate demand prediction considering seasons, holidays, and peak loads. And

  In order to achieve the above-described object, the present invention develops a plan for periodic inspection of the power generation unit within the jurisdiction of the jurisdiction and outputs the priority corresponding to the priority order of the periodic inspection of each power generation unit in the periodic inspection plan formulation device for outputting. Unit information for setting information related to the power generation unit including the rated power output of each power generation unit, the minimum power generation output, the power generation end efficiency, the ratio of power consumption required for power generation, and the fuel consumption rate to be used By using the setting means and the predetermined rate of increase in power demand from the base year, the forecast demand setting means for setting power forecast demand for each future year, month, and day, and the month, day including peak power demand, By setting the peak demand setting means for setting the hourly power forecast demand pattern and applying the hourly power forecast demand pattern to the one day power forecast demand, Periodic prediction demand creation means for calculating power demand demand by time, and periodical inspection type, start / end date and time, work process pattern, required repair costs, and appropriate interval from the previous regular inspection for each power generation unit The high-priority power generation from the information related to the power generation unit so as to satisfy the hourly power forecast demand per day calculated by the regular inspection information setting means for setting information related to the inspection and the forecast demand creation means A mode comprising: a power generation plan formulation unit that formulates a periodic inspection plan for allocating generated power based on information related to the periodic inspection in unit order; and an output unit that outputs the planned periodic inspection plan. To do.

  According to the present invention as described above, since future power demand is determined in hour units and minute units, it is possible to acquire power forecast demand with high accuracy, and each power generation according to priority at each time. Since the generated power is allocated to the units, it is possible to provide a periodic inspection plan development device and method and a control program thereof that can accurately simulate and predict future power supply and demand.

[1. First Embodiment]
[1.1. Constitution]
Next, the configuration of the first embodiment according to the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram showing the system configuration of the regular inspection plan development apparatus according to the first embodiment.

  As shown in FIG. 1, 1 sets information on power generation units such as generator output and energy efficiency for each power generation unit and specifications such as power generation priority of the power generation units. Unit information setting means. Reference numeral 2 denotes unit information storage means for storing specifications for each set power generation unit.

  Here, based on FIG. 2, the setting process of the specifications of the power generation unit by the unit information setting unit 1 and the unit information storage unit 2 will be described. FIG. 2 is an example showing a setting screen for specifications of the power generation unit. Moreover, the unit information setting means 1 sets these specifications and stores them through the unit information storage means 2 by inputting or selecting the specifications related to each power generation unit as shown below.

  As shown in FIG. 2, as the specifications of the power generation units, first, priorities indicating the priority order of allocation of generated power to each power generation unit are provided. When assigning the generated power, it is necessary to assign the generated power by giving priority to each power generation unit, for example, from a power generation unit with a low power generation cost, or prioritize a large-scale power generation unit. It is prescribed to be.

  In addition to the priority, the rated power output that is the maximum power that can be generated by each power generation unit, conversely the minimum power output that is the lowest power that cannot be reduced below a certain value, each of this rated power output and the minimum power output The rated transmission power and minimum transmission power corresponding to, the power generation end efficiency indicating the power generation efficiency of each power generation unit, the in-house utilization rate indicating the ratio of the power consumption required in the power generation unit to the power generation, and subtracting the in-house utilization rate from the power generation end efficiency Power transmission end efficiency is provided. In addition to this, information such as the unit price of the fuel used for power generation and the fuel consumption rate indicating the amount of fuel used for generating 1 kWh is provided.

  Reference numeral 3 denotes predicted demand setting means for setting the expected total power demand in the power pipe managed by the jurisdiction and the rate of future power demand growth. Reference numeral 4 denotes predicted demand storage means for subdividing and storing the predicted power total demand set by the predicted demand setting means 3 into daily predicted demand. The predicted demand setting means 3 and the predicted demand storage means 4 correspond to the “forecast demand setting means” in the claims.

  Here, based on FIG. 4, the setting process of the predicted demand of the electric power of the year, the month, and the week by the predicted demand setting means 3 and the predicted demand storage means 4 will be described. FIG. 4 is an example showing a setting screen for predicted power demand.

  The predicted demand setting means 3 calculates and sets the total demand power for each year that increases at a constant rate of increase from the reference year on the setting screen as shown in FIG. This growth rate is calculated based on comprehensive judgment based on market economic trends, large-scale capital investment, regional development plans, and other factors.

  The forecast demand storage means 4 uses the forecast monthly demand ratio and forecast demand ratio by day of the week for the forecast total demand set by the forecast demand setting means 3 to predict monthly and weekly power as follows. Calculate demand. The predicted monthly demand ratio used by the predicted demand storage means 4 is a monthly supply and demand pattern, and can be roughly predicted from past results. That is, there is a large demand for the use of heating and the like in winter, demand in spring is declining, and in summer the demand is at its peak due to the use of cooling. Therefore, the predicted demand storage means 4 calculates the monthly predicted power demand by dividing the previously calculated annual predicted power demand by this predicted monthly demand ratio.

  The demand ratio by day of the week is a weekly supply and demand pattern, which can also be roughly predicted from past performance. That is, as shown in FIG. 4, the power demand for power is greatly different between weekdays and holidays in a week, and the demand for power is higher on weekdays than on holidays. Therefore, the predicted demand storage means 4 calculates the daily power demand from the monthly power demand by dividing the previously obtained monthly demand power by the demand ratio for each forecast day of the week. And the forecast demand memory | storage means 4 memorize | stores this electric power demand of a day unit.

  Reference numeral 5 denotes a peak demand setting means for setting a predicted demand for each hour of the day including a peak of power demand in a day. 6 is a peak demand storage means for storing the predicted demand for each hour of the day including the peak set by the peak demand setting means 5.

  Here, based on FIG. 5, the predicted demand for each hour of the day including the peak set by the peak demand setting means 5 will be described. FIG. 5 is a diagram illustrating an example of a peak demand ratio (peak pattern) that is a predicted demand for each hour of the day including the peak of the day.

  As shown in FIG. 5, this peak pattern represents the daily predicted demand according to time, and further varies depending on the season. Specifically, the summertime, when there is a large demand for air conditioning, has a sharp peak pattern, and the spring and autumn seasons have a gentle pattern. There is also a difference depending on whether the power jurisdiction is cold or warm. That is, the peak pattern needs to be set according to the season and the climate of the land where the jurisdiction is in charge.

  The reason why the daily peak of power demand is taken into account is as follows. As for the daily power, the pattern is such that the power demand rises at the start of factory operation, falls during the lunch break, reaches the peak of demand in the afternoon, falls in the evening, and reaches the minimum of demand at night. Therefore, to determine whether the future power demand can be supported, it is not enough to determine whether the total daily power can be supplied, but whether stable power supply can be achieved at the peak of the daily power demand. This is because judgment is necessary.

  7 is the jurisdiction management based on the predicted daily power demand in the future stored in the predicted demand storage means 4 and the predicted demand for each hour of the day including the peak stored in the peak demand storage means 6. This is a predicted demand creating means for calculating and storing the predicted power demand per day in the power pipe for each hour. The predicted demand creating means 7 can also predict the power demand in units of minutes if the peak demand ratio is set in minutes in the peak pattern setting processing by the peak demand setting means 5, and the peak power demand It is also possible to improve the accuracy.

  8 is regular inspection information setting means for setting a future plan for regular inspection for each power generation unit. Reference numeral 9 denotes regular inspection information storage means for storing the regular inspection plan set by the periodic inspection information setting means 8.

  Here, based on FIG. 3, the routine inspection information setting process by the periodic inspection information setting means 8 and the periodic inspection information storage means 9 will be described. FIG. 3 is an example showing a screen for setting regular inspection information for each power generation unit. The regular inspection information setting means 8 sets regular inspection information that is scheduled for regular inspection of each power generation unit input via the setting screen as shown in FIG. 3, and the regular inspection information is stored through the regular inspection information storage means 9. Is memorized.

  Specifically, the set regular inspection information includes the type of regular inspection, start / end date and time, work process pattern, maintenance cost necessary for performing regular inspection, interval from the previous regular inspection, and the like. . This regular inspection information is set, for example, in accordance with regular inspection intervals stipulated by laws and regulations, set to be implemented early from the degree of deterioration of the power generation unit equipment, or set for long-term regular inspection. It is based on various circumstances of each power generation unit.

  10 is information on the power generation unit that is a specification for each power generation unit stored in the unit information storage unit 2, information on the predicted power demand by hour per day stored in the predicted demand creation unit 7, and This is a power generation plan formulation unit that formulates a regular inspection plan in which generated power is allocated to each power generation unit based on regular inspection information related to the regular inspection plan stored in the inspection information storage unit 9.

  As for the specific functions of the power generation plan formulation means 10, as shown in FIG. 1, reference numeral 101 denotes a predetermined time (from a predicted power demand by hour per day in the power line managed by the forecast demand creation means 7 for each jurisdiction. Predicted demand extracting means (corresponding to “extracting means”) for extracting the predicted total demand for one hour). 102 is a priority unassigned unit detection unit (“detection unit”) that detects a power generation unit having the highest priority based on the priority stored in the unit information storage unit 2 among the power generation units to which the generated power is not assigned. ”).

  Reference numeral 103 denotes regular inspection determination means that takes in the regular inspection information of the power generation unit stored in the regular inspection information storage means 9 and determines whether the power generation unit is in the regular inspection period. Reference numeral 104 denotes a demand determination unit that determines whether the hourly predicted demand exceeds the maximum generated power (rated power output) of the power generation unit.

  Reference numeral 105 denotes generated power allocation means for allocating generated power to the power generation unit, and has a function of subtracting the allocated generated power from the predicted total demand when the generated power is allocated. 106 is a demand allocation determination unit (corresponding to “completion determination unit”) that determines whether the allocation of the generated power for the predicted total demand at a predetermined time is completed. Reference numeral 107 denotes a reserve ratio calculation means for calculating a reserve ratio with respect to the predicted total demand at a predetermined time.

  Reference numeral 11 denotes power generation specification calculation means for calculating information such as the amount of fuel used, fuel cost, and power generation cost necessary for power generation based on the result formulated by the power generation plan formulation means 10. 12 is a summary of the periodic inspection plan formulated by the power generation plan formulation means 10 and information on the fuel consumption, fuel cost, power generation cost, etc. necessary for power generation calculated by the power generation amount calculation means 11 It is a regular inspection plan output means for outputting the plan and various amounts of power generation.

[1.2. Action]
Next, a procedure for formulating a regular inspection plan in the regular inspection formulation apparatus according to the first embodiment will be described below with reference to FIGS.

[1.2.1. Overall action]
First, as described above, the unit information setting means 1 sets the specifications by inputting or selecting the specifications including the priority of each power generation unit by the user on the screen of FIG. The specifications are stored through the storage unit 2 (S601). Further, in the periodic inspection information setting screen as shown in FIG. 3, the periodic inspection information setting means 8 sets the periodic inspection information of each power generation unit input by the user, and the periodic inspection information storage means 9 Information is stored (S602).

  Moreover, the predicted demand setting means 3 calculates and sets the total demand power for each year that increases at a constant rate from the reference year on the setting screen as shown in FIG. 4 (S603). This growth rate is calculated based on comprehensive judgment based on market economic trends, large-scale capital investment, regional development plans, and other factors. When the predicted total demand is set by the predicted demand setting means 3, the predicted demand storage means 4 calculates monthly and weekly predicted demand based on the predicted total demand (S604).

  Specifically, the predicted demand setting unit 3 calculates the monthly power demand by dividing the total annual demand power obtained previously by the predicted monthly demand ratio in the predicted demand storage unit 4. Furthermore, the daily power demand is calculated from the monthly power demand by proportionally dividing the monthly demand power by the demand ratio for each forecast day of the week. And the forecast demand memory | storage means 4 memorize | stores this electric power demand of a day unit.

  Moreover, the peak demand setting means 5 sets the peak demand ratio by inputting or selecting the peak demand ratio, which is a peak pattern of power demand in one day as shown in FIG. The contents are stored in the peak demand storage means 6 (S605). Specifically, the peak demand ratio is set by the peak demand setting means 5 according to the season and the climate of the land where the jurisdiction is in the jurisdiction, and the peak demand storage means 6 stores it.

  Note that the setting processing in S601 to 605 is not limited to the above order, and may be set first, or may be set simultaneously.

  Then, the predicted demand creating means 7 calculates the daily power forecast demand stored in the predicted demand storage means 4 and the daily peak demand ratio stored in the peak demand storage means 6 in the latter part of FIG. The hourly power demand as shown is calculated and stored (S606).

  The power generation plan formulation means 10 includes information on the power generation unit that is a specification for each power generation unit stored in the unit information storage means 2, information on the hourly power predicted demand in the pipe stored in the predicted demand creation means 7, Then, based on the regular inspection information related to the future plan of regular inspection stored in the regular inspection information storage means 9, allocation of generated power to each power generation unit is determined (S607). That is, the power generation plan formulation means 10 determines the allocation of generated power to each power generation unit that can supply power that satisfies the predicted demand in the regular inspection plan in which each power generation unit is set.

  For example, as shown in FIG. 7, the generated power is allocated from the power generation unit having a high allocation priority to the total power demand of 2,629 GWh at 1 o'clock on January 1, 2008. Here, when the power demand decreases, the low-priority power generation unit is removed from the allocation, and when the power demand increases, the unassigned power generation unit has a higher priority. assign. A specific algorithm for assigning the generated power to each power generation unit by the power generation plan formulation means 10 will be described later (FIG. 8).

  When the power generation plan formulation means 10 determines the allocation of the generated power to each power generation unit, the power generation quantity calculation means 11 receives the result, calculates various quantities, and passes through the regular inspection plan output means 12. It outputs (S608). Here, FIG. 9 is an example of an output result by the regular inspection plan output means 12.

  The “transmission power amount of each unit” in the first row in FIG. 9 is a total of monthly allocated power of each power generation unit allocated by the power generation plan formulation means 10. In addition, since this is supply electric power with respect to an electric power demand, it becomes transmission electric power at the power generation unit side. In addition, “each unit power generation amount” in the second stage in FIG. 9 is obtained by adding in-house power to transmission power, and is obtained by the calculation formula shown in FIG.

  The fuel required for power generation at the third and fourth stages in FIG. 9 is based on fuel consumption rates such as coal consumption rate, heavy oil consumption rate, gas consumption rate, etc., which are required in advance for each power generation unit. The amount of consumption can be calculated and is obtained by the second calculation formula in FIG. In addition, the consumption rate of each fuel is set by the unit information setting means 1, and can be taken in when the power generation plan formulation means 10 calculates.

  In addition, regarding the “fuel cost” in the fifth row in FIG. 9, the fuel cost of each power generation unit can be calculated from the unit price of each fuel, and is obtained by the third equation in FIG. 10. The “power generation cost” at the sixth level in FIG. 9 is calculated by the fourth generation basic unit formula shown in FIG. As described above, various quantities calculated by the power generation quantity calculation means 11 are output via the regular inspection plan output means 12.

[1.2.2. Allocation of generated power to each power generation unit]
Next, a specific algorithm for assigning the generated power to each power generation unit by the power generation plan formulation means 10 will be described below based on the flowchart of FIG.

  First, the predicted demand extracting unit 101 extracts the predicted total demand at a predetermined time (one hour) from the predicted demand for each hour in the power pipe managed by the jurisdiction stored by the predicted demand creating unit 7 (S801). Then, based on the priority of each power generation unit stored in the unit information storage unit 2, the priority unassigned unit detection unit 102 detects the power generation unit to which the highest priority generated power is not assigned (S802). .

  When the unassigned unit is detected by the priority unassigned unit detection unit 102 (YES in S802), the regular inspection determination unit 103 takes in the regular inspection information of the power generation unit stored in the regular inspection information storage unit 9. Then, it is determined whether it is during the regular inspection period (S803). When it is determined by the regular inspection determining means 103 that it is not during the regular inspection period (NO in S803), the demand determining means 104 exceeds the maximum predicted power generation (rated power generation output) of the power generation unit. Is determined (S804).

  When the demand determination unit 104 determines that the predicted total demand exceeds the maximum generated power of the power generation unit (YES in S804), the generated power allocation unit 105 allocates the maximum generated power to the power generation unit ( S805). On the other hand, when it is determined by the demand determination means 104 that the predicted total demand is less than or equal to the maximum generated power of the power generation unit (NO in S804), the generated power allocation means 105 gives the predicted total demand to the power generation unit. (S806).

  When generated power is allocated to the power generation unit by the generated power allocation unit 105 (S806, S806), the generated power allocation unit 105 subtracts the allocated generated power from the predicted demand (S807). Then, the demand allocation determining unit 106 determines whether the allocation of the generated power corresponding to the predicted demand at the time is completed (S808), and if not completed (NO in S808), the above S802 The processes up to 807 are repeated, and the allocation up to the predicted demand at that time is performed.

  When it is determined by the demand allocation determination means 106 that the allocation of the generated power for the predicted total demand at the time has been completed (YES in S808), the reserve ratio calculation means 107 corresponds to the predicted total demand at the time. The reserve ratio is calculated (S809). This reserve rate is a value obtained by dividing the maximum power that can be supplied by demand power. If it is explained at 1 o'clock on January 1, 2008 shown in FIG. Is a value obtained by dividing the total by 2,629 GWh, which is the total demand. Normally, 5% to 10% of this reserve ratio is necessary for stable power supply.

  When the reserve ratio is calculated by the reserve ratio calculating means 107, the predicted demand extracting means 101 takes in the predicted total demand at the next time, and the same allocation process as described above is repeatedly performed. When the predicted demand extracting unit 101 takes in the predicted total demand until the period of the regular inspection plan formulation and determines that the above allocation has been completed (S810), the allocation process of the generated power to the power generation units ends.

  If it is determined by the regular inspection determining means 103 that the regular inspection period is in progress (YES in S803), the generated power cannot be allocated to this power generation unit. Based on the priority of each power generation unit stored in the unit information storage unit 2, the allocation unit detection unit 102 detects a power generation unit to which the next highest generated power is not allocated, and the above processing is repeated (S802). .

  If no unassigned unit is detected by the priority unassigned unit detection unit 102 (NO in S802), the assignment is impossible and the routine is determined to be invalid (S811).

  Although not shown, in the algorithm of FIG. 10, when the reserve ratio calculated by the reserve ratio calculating means 107 is low, a method of increasing the reserve ratio is adopted. Specifically, when the reserve ratio is low, instead of allocating the generated power to another power generation unit, the allocated generated power including the already allocated power generation unit is lower than the rated generated power. Assign with. According to this method, the total rated transmission power of the assigned power generation units becomes large, and stable supply with an increased reserve rate can be realized.

  Although the power generation efficiency is reduced and costs are required, the following method for securing the reserve ratio can also be adopted. Specifically, even when the above-described method is used, in the case where the reserve ratio falls below a specified value or there are no power generation units to be allocated, supply that satisfies the demand cannot be performed, so stable supply is possible. Cannot be realized.

  For this reason, the regular inspection period is reviewed by the regular inspection information setting means 8, and the generation plan allocation means 10 again formulates the allocation of the generated power to each power generation unit. According to this method, the power generation efficiency is reduced and the cost is increased, but the reserve ratio can be ensured to be increased. In addition, FIG. 11 shows an example of the position of the result of obtaining the availability of allocation and the reserve ratio in the power generation plan formulation means 10 in this way.

[1.3. effect]
According to the first embodiment as described above, since the future power demand is obtained in units of hours and minutes, an accurate power demand forecast can be acquired. Furthermore, since generated power is allocated to each power generation unit according to the priority at each time, it becomes possible to simulate and predict future power supply and demand.

  Therefore, when determining the regular inspection of each power generation unit, it is possible to supply the expected power demand in the future to the jurisdiction of the jurisdiction, or supply with a stable reserve rate You can get information on what is possible. This makes it possible to make an accurate and accurate regular inspection plan and contribute to a stable supply of electric power.

In addition, since the fuel consumption, fuel cost, and unit price of power generation are calculated, it becomes possible to grasp the future operation cost and cost, and it is possible to accurately grasp the maintenance plan and the budget formulation. In addition, since it is easy to recalculate by changing the regular inspection period of each power generation unit, it is possible to confirm the influence on the fuel cost and the power generation cost while changing the regular inspection period. Specifically, for example, a large power generation unit is operated at a time when the demand is the highest, and if the regular inspection is performed at a time when the demand is small, the overall operation efficiency is higher. By adjusting the fuel cost and predicting the fuel cost, the fuel cost can be reduced, and a maintenance plan that can reduce CO ₂ emissions can be formulated, which contributes to the reduction of the global environmental load. it can.

[2. Second Embodiment]
[2.1. Constitution]
Next, the configuration of the second embodiment according to the present invention will be described below with reference to FIG. FIG. 12 is a block diagram illustrating a system configuration of the regular inspection plan development apparatus according to the second embodiment.

  In the second embodiment, as shown in FIG. 12, instead of the unit information setting means 1 and the unit information storage means 2 provided in the first embodiment, electric power based on sales contracts with other companies, wind power / solar power generation Power generation information setting means 13 ("special power generation information setting means") that can set information on special power generation units such as hydropower generation that requires consideration of water discharge rate, pumped-storage power generation that works as motive power, and accommodation to borrow power from others Power generation information storage means 14 for storing the set information.

  Here, the setting contents by the power generation information setting means 13 will be described below with reference to FIG. FIG. 13 is an example showing the setting screen of the specifications of the conventional normal power generation unit on the left side and the specifications of the special power generation unit on the right side.

  As shown in FIG. 13, the special power generation unit does not have the priority provided in the first embodiment, and can arbitrarily generate power and cannot arbitrarily generate power indicating whether or not arbitrary power adjustment is possible. There is a power generation type that can set one of the flood season restrictions, the power supply, the interchangeable power supply, etc. that indicate the flood season restrictions that are affected by precipitation. The following [2.2. The power generation plan formulation means 10 takes in this power generation type set by the power generation information setting means 13 and stored through the power generation information storage means 14, and allocates the generated power to the special power generation unit. Do.

  Therefore, in the second embodiment, the power generation plan formulation unit 10 has the following functions. The priority unassigned unit detection means 102 not only detects the power generation unit based on the priority, but also based on the invention type of the special power generation unit stored in the power generation information storage means 14, the generated power is not assigned It has a function to preferentially detect units such as IPP, which are units that cannot adjust power generation, and wind power / solar power generation units, and hydroelectric power generation units in the flood season.

  In addition, under a predetermined condition, the generated power allocation unit 105 has a function of allocating generated power corresponding to the minimum load of the special power generation unit to the special power generation unit and allocating the surplus power to the pumped power generation power source. is doing. Further, the generated power allocation means 105 has a function of allocating interchanged power to the special power generation unit.

  As shown in FIG. 12, reference numeral 108 denotes minimum load determination means for determining whether the predicted total demand is below the minimum load of the special power generation unit. Reference numeral 109 denotes an accommodation power determination unit that determines whether the remaining total demand is within a range that can be allocated by the accommodation power when the unassigned special power generation unit is not detected by the priority unassignment unit detection unit 102. is there. ,

  Since the other configuration is the same as that of the first embodiment, the description thereof is omitted, and the same reference numerals are given. Further, the configuration of the regular inspection plan development apparatus according to the second embodiment naturally includes an aspect having the unit information setting unit 1 and the unit information storage unit 2 provided in the first embodiment.

[2.2. Action]
Next, the procedure for formulating a regular inspection plan in the regular inspection formulation apparatus according to the second embodiment will be described. However, since the main overall operation is the same as that of the first embodiment, the explanation is omitted, and the power generation plan formulation unit 10 An algorithm for assigning the generated power to the special power generation unit will be described below with reference to FIG.

  First, similarly to the first embodiment, the predicted demand extracting unit 101 calculates the predicted total of a predetermined time (one hour) from the predicted demand for each hour in the power line managed by the jurisdiction stored by the predicted demand creating unit 7. The demand is extracted (S1401). In the second embodiment, the priority unassigned unit detecting means 102 is a unit that is unassigned and cannot be arbitrarily adjusted based on the invention type of the special power generation unit stored in the power generation information storage means 14. Are preferentially detected for units such as IPP, wind power / solar power generation units, and hydropower generation units in the flood season (S1402). That is, in the subsequent processing, these special power generation units are detected so that the contracted power and the expected generated power are preferentially allocated.

  When the unassigned special power generation unit is detected by the priority unassigned unit detecting means 102 (YES in S1402), the regular inspection determining means 103 is the regular inspection information storage means 9 as in the first embodiment. The regular inspection information of the special power generation unit stored in the above is taken in, and it is determined whether it is during the regular inspection period (S1403). When it is determined by the regular inspection determination means 103 that the period is not within the regular inspection period (NO in S1403), the demand determination means 104 determines that the estimated total demand taken is the maximum generated power (rated power output) of the special power generation unit. It is determined whether it exceeds (S1404).

  When the demand determination unit 104 determines that the predicted total demand exceeds the maximum generated power of the special power generation unit (YES in S1404), as in the first embodiment, the generated power allocation unit 105 performs the special power generation. This maximum generated power is allocated to the unit (S1405). On the other hand, when it is determined by the demand determination unit 104 that the predicted total demand is less than or equal to the maximum generated power of the special power generation unit (NO in S1404), in the second embodiment, the minimum load determination unit 108 It is determined whether the total demand is below the minimum load of the special power generation unit (S1406).

  When it is determined by the minimum load determination means 108 that the predicted total demand is below the minimum load of this special power generation unit (YES in S1406), the generated power allocation means 105 allocates the generated power corresponding to this minimum load. Then, the surplus power is allocated to the power source of the pumped storage power generation (S1407). That is, since this special power generation unit cannot allocate power smaller than the allowable minimum output, the generated power allocation means 105 allocates the generated power corresponding to this minimum load, and then uses the surplus power as the power of pumped storage power generation. It works by keeping the balance between supply and demand by making it negative by assigning it to the power source.

  On the other hand, when the minimum load determination means 108 determines that the predicted total demand is greater than or equal to the minimum load of the special power generation unit (NO in S1406), the generated power allocation means 105 The generated power corresponding to the predicted total demand is allocated (S1408).

  Further, in S1402, if no unassigned special power generation unit is detected by the priority unassigned unit detection means 102 (NO in S1402), that is, if there is a demand that cannot be adjusted in the own power pipe, the interchanged power The determination unit 109 determines whether or not the remaining total demand is within a range that can be allocated with the available power (S1409). If the total power demand is determined to be within a range that can be allocated by the accommodation power (YES in S1409), the generated power allocation means 105 allocates this accommodation power to the special power generation unit. (S1410). On the other hand, if it is determined by the accommodation power determining means 109 that the remaining total demand is not within the range that can be allocated by the accommodation power (NO in S1409), it is determined that the allocation is impossible and the regular inspection plan is invalid. Ends (S1411).

S1406 to 1408, and S1412 to 1415, which are processes after the generated power is allocated to the special power generation unit by the generated power allocation unit 105 in S1410, are the same as S807 to 810 according to the first embodiment, and thus will be described. Is omitted.
FIG. 15 shows an example in which the power generation plan is assigned to the normal power generation unit and the special power generation unit by the power generation plan formulation means 10 as described above.

[2.3. effect]
According to the second embodiment as described above, the following effects can be obtained as compared with the first embodiment. In the first embodiment, since the electric power allocated to the power generation unit can be generated within a certain range without conditions, the power generation unit is assumed to be a general power generation unit such as a thermal power generation unit.

  However, in practice, the power source of the power system is composed of a wide variety of power sources. For example, a unit that sells generated power called IPP usually supplies a certain amount of power, not a power command and a desired amount of power generation. Similarly to this, power is not issued by generating a power command. Also, hydroelectric power generation can generate power during the season when precipitation is secured, but power generation is low during the season when precipitation is low. Therefore, for such a special power generation unit, it is not appropriate to formulate a regular inspection plan that enables generation of electric power to be allocated within a certain range without conditions as in the first embodiment.

  Therefore, in the second embodiment, the power generation information setting means 13 borrows power from a sales contract with another company, wind power / solar power generation, hydroelectric power generation that requires consideration of the water discharge rate, pumped-storage power generation that works as power, and other power. By adding as an operating condition for special power generation units such as flexibility, it becomes possible to formulate a power generation plan that matches the actual system operating conditions.

  In particular, pumped-storage power generation can use surplus generated power for pumping, so both hydropower generation and pumped-storage power generation can supply power within a certain range by assigning supply power and issuing a power generation command. In addition, it is possible to take advantage of the feature that the response is high and the peak load can be flexibly handled. In addition, when it comes to accommodation, it can be interchanged with other power pipes, which helps to provide a stable supply.

  As a result, the accuracy of the regular inspection plan to be formulated will increase, so even if regular inspections are carried out as planned for special power generation units such as those mentioned above, problems with power supply and demand will be suppressed, and the reserve ratio will decrease. It is possible to prevent the influence of the power supply on the stable power supply.

[3. Third Embodiment]
[3.1. Constitution]
Next, the configuration of the third embodiment of the present invention will be described below with reference to FIG. FIG. 16 is a block diagram showing the system configuration of the regular inspection plan development apparatus according to the third embodiment.

  In the third embodiment, as shown in FIG. 16, the predicted demand setting means 3, the predicted demand storage means 4, the peak demand setting means 5, the peak demand storage means 6, and the predicted demand creation means provided in the first embodiment. 7 instead of 7, the supply and demand result input means 15 (which corresponds to “demand result setting means”) for capturing the power supply result data of the last year and the most recent years, and the power supply result data input by the supply and demand result input means 15 this year The actual reference predicted demand generating means 16 for correcting the day of the week different from last year or the most recent year, and the actual reference predicted demand storing means 17 for storing the demand predicted data generated by the actual reference predicted demand generating means 16 are provided.

  In the periodic inspection plan formulation device according to the third embodiment, the demand forecast is made based on the power supply record of the last year or the most recent years as a reference. It has a function to capture supply performance data. The supply and demand result input means 15 is configured to be able to input from the collection device by using, for example, a collection device that collects demand and supply data in the power pipes every minute or every second. It is configured in such a manner that data can be collectively fetched.

  In addition, the demand results for last year and the most recent years input by the supply and demand result input means 15 take into account the fluctuation factors of the supply and demand depending on the seasons. The supply and demand fluctuation factors are shifted. For this reason, the standard predicted demand generation means 16 corrects the shift in the supply and demand fluctuation factors on weekdays and holidays. The performance-based forecast demand generating means 16 includes calendar information, and is configured to be able to determine the date, day of the week, and holiday for the current fiscal year, the next fiscal year, and the future. Of course, the power demand growth rate shown in FIG. 4 is also provided.

  The performance standard predicted demand storage means 17 stores the demand prediction data corrected by the performance standard predicted demand generation means 16.

  Since the other configuration is the same as that of the first or second embodiment, the description thereof is omitted, and the same reference numerals are given. Moreover, the structure of the regular inspection plan formulation device according to the third embodiment includes the predicted demand setting means 3, the predicted demand storage means 4, the peak demand setting means 5, and the peak demand storage means provided in the first embodiment. Of course, the aspect which has the forecast demand preparation means 7 is also included.

[3.2. Action]
The procedure for formulating the regular inspection plan of the regular inspection formulation apparatus according to the third embodiment is only that the corrected predicted demand stored in the actual reference predicted demand storage means 17 is used instead of the predicted total demand for power. Since the second embodiment is different from the first embodiment and other than that is common to the first embodiment, description thereof is omitted. Therefore, in the following, with respect to the demand record input by the supply / demand record input unit 15, the correction process for the shift of the supply / demand fluctuation element on weekdays / holidays in the record standard predicted demand generation unit 16 will be described with reference to FIG. . In FIG. 17, on the left side, an example of demand forecast data, which is one-hour cycle demand / supply actual data input by the demand / demand performance input means 15 using a demand data collecting device or the like, is shown. More specifically, demand data corresponding to the date, time, and day of the week is recorded.

  First, the performance-based predicted demand generation means 16 takes in the demand prediction data which is the supply / demand actual data set by the supply / demand actual input means 15. Here, since the demand increase rate is different between weekdays and holidays, the actual demand forecast generation means 16 takes out data on the same day of the same week as the day when the forecast demand is created, The forecast demand data is generated by multiplying the demand increase rate according to the day of the week.

  In addition, since the actual standard forecast demand generating means 16 takes into account national holidays, the national holiday in the base year is compared with the national holiday in the year in which the demand is forecasted, and the date is fixed. In the case of, demand data for the forecast year is generated by multiplying the base year data by the demand increase rate for holidays. On the other hand, in the case of a national holiday whose date is not fixed, the demand increase rate in the case of a holiday is multiplied by the national holiday data of the date of the base year closest to the national holiday date of the forecast year. This generates forecast demand data for the forecast year.

  In addition, if the data for the same day of the same week is a national holiday in the base year but is not a national holiday in the forecast year, it is a weekday for normal day data that is not a national holiday in the same week in the base year. The forecast demand data of the forecast year is generated by multiplying the demand increase rate in the case of. Then, by repeating this process, predicted demand data for the regular inspection plan formulation period is generated, and the actual reference predicted demand storage means 17 stores these predicted demand data as predicted total demand.

[3.3. effect]
According to the third embodiment as described above, it is possible to obtain an extremely reliable predicted total demand that takes into consideration the results of last year or the most recent years, the demand increase rate on weekdays and holidays / holidays, and the growth rate. Become. Therefore, in the regular inspection plan development device according to the third embodiment, the high-accuracy power generation plan and regular inspection plan are formulated because the regular inspection plan is formulated using this reliable predicted total demand. be able to.

  In addition, since past demand records are usually recorded for multiple years, the periodic inspection plan is repeatedly verified by entering multiple patterns, such as the year when the demand is hot and the year when the demand is cold is low Therefore, it is possible to formulate a regular inspection plan that can provide a stable supply even when weather changes and natural conditions deteriorate.

[4. Fourth Embodiment]
[4.1. Constitution]
Next, the configuration of the fourth embodiment according to the present invention will be described below with reference to FIG. FIG. 18 is a block diagram showing the system configuration of the regular inspection plan development apparatus according to the fourth embodiment.

  In the fourth embodiment, the power generation plan is formulated so that it can be accurately formulated in consideration of various conditions. Therefore, as shown in FIG. 18, the configuration of the second embodiment is adopted. The operation condition setting means 18 for setting various conditions as described below is added. For example, when formulating a power generation plan, there are some special conditions that must be taken into account in each power pipe. First, condition setting based on system stability will be described based on FIG.

  In general, there is a wide-area power system in the jurisdiction of the jurisdiction, and a plurality of power generation units are connected to it. Here, an area where a large number of power generation units are connected to the system is stable in terms of a power supply system, but a weak power system is an area far from an area where a large number of power generation units are connected. For this reason, the system of the power generation units 3 and 4 shown in FIG. 19 is not connected to a large number of power generation units, but is a weak system far away from the power generation units 1, 2, 5, etc. One of the units 3 and 4 must always generate power and stabilize the system. That is, the operating condition setting means 18 sets a system stability condition such that any one of the power generation units 3 and 4 is operating.

  In addition, for fuel gas (LNG, LPG), overseas coal, etc., it is common to make a multi-year transaction contract for the stable supply of fuel. For this reason, since it is necessary to consume all the predetermined amount of transaction for the specific fuel, the operating condition setting means 18 sets a condition for using this amount of transaction. Furthermore, when a power generation unit is newly constructed, electric power is generated by a trial run that is performed for a long time during the construction. Therefore, in order to preferentially incorporate the electric power generated in the trial operation into the power generation plan, the condition of the trial operation plan is set by the operation condition setting means 18.

  Since the configuration other than the above is the same as that of the second embodiment, the description thereof is omitted and the same reference numerals are given.

[4.2. Action]
Next, the procedure for formulating the regular inspection plan in the regular inspection formulation apparatus according to the fourth embodiment will be described. However, since the main overall operation is the same as that of the second embodiment, the description is omitted, and the operation condition setting means 18 A procedure for setting various conditions and allocation of generated power will be described with reference to FIG. FIG. 20 is an example of a setting screen for various conditions by the operating condition setting means 18.

  Here, it is possible to set operating conditions for system stabilization, conditions for fuel, conditions for trial operation, and the like. Therefore, when any condition is input or selected by the user, the operating condition setting means 18 sets this condition as a priority condition in formulating the regular inspection plan. Further, when the unit information storage unit 2 stores these priority conditions, the power generation plan formulation unit 10 formulates a power generation plan in consideration of the priority conditions.

  For example, as shown in FIG. 20, the generated power is assigned to the power generation unit C having a low priority after the power generation unit A having a higher priority. However, when an operation constraint for system stability is input or selected by the user, the operation condition setting means 18 sets the system stability condition, and thus when power generation of the power generation unit C is indispensable, In the power generation plan formulation means 10, the priority order is changed, and the power demand is preferentially assigned to the power generation unit C.

  In addition, in the trial operation power generation at the time of construction and the trial operation after the regular inspection, the power generation amount planned in advance cannot be changed. Therefore, when the condition for the trial operation is input or selected by the user, the operation condition setting means 18 sets the condition for the trial operation plan. By performing the setting, in the power generation plan formulation means 10, the priority order of the target power generation units is changed to a higher rank, and power demand is preferentially allocated.

  In addition, considering the case where it is contracted to purchase and use a fixed amount every year for the purpose of local industry development such as domestic charcoal and gas, etc. The setting means 18 sets the fuel usage conditions. Thus, until a certain amount of fuel such as domestic charcoal or gas is used, the power generation plan formulation means 10 changes the priority order of the target power generation units to a higher rank and preferentially allocates power demand.

[4.3. effect]
According to the fourth embodiment as described above, system stability conditions, fuel use conditions, test operation conditions, and the like are added as operation conditions, and therefore more accurate near actual operation corresponding to various conditions in the jurisdiction of the jurisdiction. It is possible to formulate a simple power generation plan.

[5. Fifth Embodiment]
[5.1. Constitution]
Next, the configuration of the fifth exemplary embodiment of the present invention will be described below with reference to FIG. FIG. 21 is a block diagram illustrating a system configuration of a regular inspection plan development apparatus according to the fifth embodiment.

  In the fifth embodiment, as shown in FIG. 21, in the configuration of the second embodiment, in all the power generation units, there are various kinds of scaffold assembly personnel, device disassembly personnel, device inspection personnel, etc. that are required within the regular inspection period. A regular inspection quantity calculation means 19 for calculating the number of personnel is added.

  This regular inspection amount calculation means 19 has a master table which is a regular inspection personnel plan (standard) showing the distribution of the number of personnel with respect to the relative number of days from the start of regular inspection as shown in FIG. The total number of personnel such as scaffold assembly personnel, equipment disassembly personnel, equipment inspection personnel, etc. that are required in the future is calculated, and the total number of personnel of all power generation units in the regular inspection period is calculated. Further, the regular inspection quantity calculation means 19 also determines when the regular inspections overlap in a plurality of power generation units serving as bottom necks based on the calculated total number of personnel.

  The allocation of personnel shown in this master table is described in [5.2. As described in [Action], correction can be made based on the type of regular inspection, the population pattern of regular inspection, and the like.

[5.2. Action]
Next, the procedure for formulating a regular inspection plan in the regular inspection formulation apparatus according to the fifth embodiment will be described. However, since the main overall operation is the same as that in the second embodiment, the explanation is omitted, and regular inspection various amount calculation means The procedure for allocating personnel having various skills in 19 will be described with reference to FIGS.

  When the power generation quantities calculation means 11 calculates the power generation quantities of each power generation unit, the regular inspection quantities calculation means 19 first takes in a master table that is a regular inspection personnel plan that it has. Here, since the scale of the regular inspection greatly varies depending on the type of regular inspection, the regular inspection amount calculation means 19 uses the personnel distribution shown in this master table for the formulation in the power generation plan formulation means 10, for example. Corrections are made based on regular inspection types such as self-inspection, intermediate inspection, and legal inspection set by the regular inspection information setting means 8.

  In addition, in the regular inspection, there are cases where disassembly inspection is performed or not, polishing / repairing is performed, and cases where it is not performed, etc.Therefore, the regular inspection amount calculation means 19 calculates the personnel distribution shown in this master table. The correction is made based on the population pattern in the regular inspection information set by the regular inspection information setting means 8. Further, the regular inspection quantity calculation means 19 compiles the repair costs for each regular inspection set by the regular inspection information setting means 8 so as to formulate a long-term plan for repair costs, and to create a long-term plan for the budget. If it is impossible to repair, it will be leveled.

  Then, the regular inspection quantity calculation means 19 performs the regular inspection period at all power stations as shown in FIG. The total number of various personnel required is calculated every day. Further, although not shown in the figure, the regular inspection quantity calculation means 19 determines the duplication of regular inspections in a plurality of power generation units serving as bottom necks by comparing the total number of the various personnel with the equipment. Through the plan output means 12, the calculated duplication of regular inspections as a bottom neck and the total number of various personnel are output.

[5.3. effect]
According to the fifth embodiment as described above, the number of necessary personnel and the total number of equipment can be grasped by duplication of the regular inspection process planned for each power generation unit, which becomes a bottleneck. It becomes possible to take measures such as readjustment of duplication of regular inspections and addition of necessary personnel.

  In particular, the regular inspection of power generation units involves disassembling, inspecting, adjusting, and commissioning a vast amount of equipment, which requires a large number of personnel and personnel with special skills and qualifications at each work stage. Indispensable. Therefore, by displaying the duplication of regular inspections that become the bottom neck and the total number of various personnel, and calling attention, it is possible to prevent the shortage of personnel and obstruction of work progress when multiple unit regular inspections overlap. Can be prevented.

  In addition, it is possible not only to avoid unreasonable regular inspection plans, but also to standardize regular inspection staff and regular inspection costs, so that it is possible to formulate regular inspection plans with high efficiency in terms of management. Become.

[6. Sixth Embodiment]
[6.1. Constitution]
Next, the configuration of the sixth embodiment of the present invention will be described below with reference to FIG. FIG. 24 is a block diagram showing the system configuration of the regular inspection plan development device according to the sixth embodiment.

  In the sixth embodiment, in order to find an optimal regular inspection plan while automatically changing regular inspection information, the configuration of the second embodiment includes a convergence information storage unit 20 (“convergence information setting unit”). ”), And a converging calculation executing means 21 and a regular inspection plan changing means 22 are provided. The convergence information storage means 20 stores a convergence mode as shown in the upper part of FIG. 25, and is configured in such a manner that this convergence mode can be selected.

The convergence mode indicates a convergence item when the convergence is calculated. For example, the fuel cost priority mode is a mode for obtaining a regular inspection plan that can minimize the total fuel cost. Further, the CO ₂ reduction priority mode is a mode for obtaining a regular inspection plan by calculating convergence so as to minimize the total CO ₂ .

  The convergence calculation execution means 21 obtains the optimum regular inspection plan by recalculating the regular inspection plan formulated by the power generation plan formulation means 10 based on the predetermined constraints and restrictions as shown in FIG. . Specifically, as shown in the middle of FIG. 25, for example, if the regular inspection type of the regular inspection plan is legal inspection, the law requires that inspection be conducted within four years. There should be no more than four years from the inspection. Conversely, conducting a legal check within a short period of time is nothing but a wasteful expense, so the minimum period of 3 years and 6 months is provided.

  The convergence calculation execution means 21 performs recalculation while automatically adjusting the regular inspection time within this adjustment period. It is possible to set the number of days to be automatically adjusted, and as shown in the lower part of FIG. 25, for example, calculation is performed while automatically adjusting in units of 10 days or the like. For example, based on the regular inspection type, regular inspection date, regular inspection interval, etc. of each power generation unit as shown in FIG. 26, the convergence calculation execution means 21 recalculates each regular inspection while adjusting it automatically. .

  The specific functions 2101 to 2106 (see FIG. 24) of the convergence calculation execution means 21 are described in [6.2. This will be described in detail in the section of [Action].

  The regular inspection plan changing means 22 automatically sets the regular inspection date and time created by the convergence calculation executing means 21 through the regular inspection information setting means 8.

[6.2. Action]
Next, the procedure for formulating a regular inspection plan in the regular inspection formulation apparatus according to the sixth embodiment will be described. However, since the main overall operation is the same as that of the second embodiment, the description thereof will be omitted, and through the convergence information storage means 20 With reference to FIG. 27, the re-planning procedure of the regular inspection plan by the convergence calculation execution means 21 and the power generation plan formulation means 10 for the selected convergence mode will be described.

  Based on the regular inspection plan formulated in the power generation plan formulation means 10, the following regular inspection plan is formulated on the assumption that the inspection type restrictions and restrictions shown in FIG. 25 are imposed. Explain the procedure. Therefore, explanation of this point is omitted. Further, it is assumed that a desired mode is selected in the convergence information storage unit 20 among the convergence modes shown in FIG.

  First, the combination calculation unit 2101 determines the number of each power generation unit, the number of regular inspections of each power generation unit, and the regular inspection start of each regular inspection based on the regular inspection plan of each power generation unit formulated by the power generation plan formulation unit 10. All combinations of date to end date are calculated (S2701). Specifically, the combination calculation unit 2101 first calculates the combination by [Equation 1] when the number of target power generation units is S and there are T regular inspections to be calculated for each power generation unit. .

[Equation 1]
S! * T!

  Then, the calculation result of [Equation 1] is all multiplied by [Equation 2] obtained by multiplying the calculation result of [Equation 1] by the interval days (in this case, n) that are the regular inspection start and end dates that are the regular inspection interval days Each combination of is calculated.

[Equation 2]
S! * T! * N

  When all combinations are calculated based on [Equation 2] by the combination calculation unit 2101, the combination information storage unit 2102 temporarily stores the regular inspection start / end dates at the time of each combination (S2702). . Here, the combination extraction means 2103 extracts one regular inspection start / end date at the time of combination from the regular inspection start / end dates at the time of each combination stored by the combination information storage means 2102, and this is generated. The data is sent to the plan formulation means 10 (S2703).

  Then, the power generation plan formulation unit 10 formulates a regular inspection plan again based on the sent combination regular inspection start / end dates in the same manner as in the second embodiment (S2704). When the regular inspection plan is formulated again by the power generation plan formulation unit 10, the redevelopment plan storage unit 2104 temporarily stores the regular inspection plan (S2705).

  Then, the combination completion determination unit 2105 determines whether the processing from S2603 to 2605 has been repeated for the calculated number of combinations (S2706). If the combination completion determination unit 2105 determines that the processing has been completed for all the combinations (YES in S2706), the convergence mode plan extraction unit 2106 (corresponding to “specific information extraction unit”) determines in S2605. The calculation items for which power demand could not be supplied are removed from the temporarily stored regular inspection plan, and the minimum or maximum calculation item corresponding to the convergence mode selected by the convergence information storage means 20 is extracted from the remaining calculation items. (S2707). At the same time, the minimum or maximum calculation items corresponding to the extracted convergence mode are sent to the power generation amount calculation means 11, and the regular inspection plan that best matches the convergence mode is output from the regular inspection plan output means 12.

[6.3. effect]
According to the sixth embodiment as described above, an optimal solution can be obtained automatically and for each index. Compared to the conventional method that employs the plan, it is possible to significantly reduce the time required for formulating the regular inspection plan. Furthermore, it is possible to easily find a periodic inspection plan that aims to reduce the fuel cost in terms of management and an inspection plan that minimizes the environmental impact on the earth. It can also contribute to improvements in power supply and stable power supply.
