BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coal storage plan coal arrangement planning method suitable for use in the operation of a coal storage plant in a coal-fired power plant.

[0002]

2. Description of the Related Art In a coal-fired power plant, coal carried by a ship is carried by a belt conveyor to a coal storage yard. A coal storage yard is configured by arranging a plurality of piles, which are places for storing coal. In this coal yard, the coal that is carried is loaded by a stacker, discharged by a reclaimer according to the required amount of power generation, and sent to a bunker. The operations such as loading, discharging, and coal transfer are controlled by a coal stock yard operation system composed of a plurality of machines so as not to hinder continuous operation of the power plant.

In the above-mentioned coal yard operation system, in order to effectively use the coal yard, a long-term plan such as the location of coal is made based on the situation of the current coal yard. As an example of this coal allocation planning method, a method of collectively planning for two weeks is known. The flow is shown below. Determine the amount of electricity generated annually and calculate the amount of coal corresponding to it. Plan to ship for 3 months. From the day of the planning date, plan to load / unload coal for two weeks. Based on the above-mentioned two-week loading / discharging plan, two-week coal allocation, that is, how much coal is to be placed at which position in which pile in the coal storage yard is planned. This plan includes, for example, the determination of the placement location when a large amount of coal is carried in by the ship allocation plan, and the determination of the amount of coal to be paid out and the type of coal for the required power generation amount of. As a result, a coal storage map, which is a coal layout map of the coal storage, is created for two weeks. This processing is executed by a program of embedded software. Create a work order for the day based on the plan. Based on the above work instructions, coal is actually loaded and discharged.

[0004]

By the way, in the operation of the above-mentioned coal storage yard, the coal allocation for 2 weeks is planned based on the coal loading / delivery plan for 2 weeks set on the day of the plan. ing. For this reason, when the work was not performed according to the work instruction, there was a case where a quantitative difference occurred between the coal storage map at the time of planning and the coal storage map after the actual work. In such a case, there is a problem that the above process and the above process must be performed again on the day when the deviation occurs, and the planning after that day must be redone, which takes time and labor.

The present invention has been made under such a background, and an object of the present invention is to provide a coal stock yard coal allocation planning method capable of effectively allocating a coal stock yard without spending time and effort. And

[0006]

A coal stockyard coal allocation planning method according to a first aspect of the present invention is based on a coal stowage plan for the entire coal stockyard within a certain period and a coal delivery plan from the entire coal stockyard. , A coal allocation plan of the coal storage for the certain period is created by performing the coal allocation operation for the certain period for the coal allocation situation of the coal storage at that time, and the operation procedure in the allocation operation is recorded. Incidentally, every time the date is updated, with respect to the actual coal arrangement situation of the day before the coal yard, by performing the allocation operation in the fixed period according to the recorded operation procedure, the actual coal arrangement situation and A feature is that a deviation from the coal placement plan is detected and the coal placement plan is corrected based on the detection result.

According to the invention of claim 2, the method for planning coal placement in a coal storage yard according to the invention of claim 1 is based on a loading plan of coal for the entire coal yard and a delivery plan of coal from the coal yard. While performing the coal allocation operation for the coal allocation situation of the coal storage yard at the time, record the operation procedure in the allocation operation, if the same operation as the recorded operation procedure is performed, according to the operation procedure, The feature is that a coal allocation plan is created by performing allocation operations for the status of coal allocation from the next day.

In the coal stock yard coal allocation planning method according to the third aspect of the present invention, when the allocation operation is performed with respect to the coal allocation status of the coal yard, the coal yard is continued in the coal yard currently arranged in the coal yard. Then, when loading a pile of coal, the height of the pile of coal arranged in the coal stockyard is compared with the height of the pile of coal that is continuously loaded, and the height of the pile of coal is compared. If the height of the coal is the same, select the stacking method of horizontally stacking the pile of coal of the specified height, and if the height of the pile of coal is different, lower the pile of coal to the specified height. Select the loading method to be loaded up to this point, and add up the loading amount of the pile of coal arranged in the coal storage yard and the loading amount of the pile of coal to be continuously loaded to obtain the total loading. The loading amount is calculated, and the loading bottom area is calculated from the total loading amount and the height of the pile of coal continuously loaded, and the loading method And said bottom area stowage is characterized by displaying on the coal storage and.

[0009]

According to the first aspect of the present invention, the operation procedure of the allocation operation performed in advance is recorded, and the allocation operation is performed again based on the actual coal arrangement condition at that time. , Even if there is a difference between the coal allocation situation of the coal yard after the actual loading and unloading and the coal allocation plan created in advance, the loading and unloading plans are input again. There is no need to wait and wait for the allocation operation to be performed again, and the time required for correction can be reduced considerably.

According to the second aspect of the invention, the operation procedure of the allocation operation performed in advance is recorded, and when the same operation as the recorded allocation operation is performed, the operation procedure is performed to perform the operation. Since the subsequent coal placement plan is created, the time required for the coal placement plan can be shortened.

According to the third aspect of the present invention, a stacking method of horizontally stacking coal mountains having a specified height from the height of the coal mountains, or a low coal mountain is specified. Select one of the stowage methods to stow up to the height, calculate the stowage bottom area from the total stowage amount and the height of the coal pile, and then use those stowage methods and the stowage bottom area. Therefore, regardless of which of the above loading methods is used for loading the piles of coal placed in the coal yard, refer to the loading method and bottom area for loading displayed on the coal yard. By doing
It is possible to continue to load the pile of coal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. §1. First Embodiment FIG. 1 is a block diagram showing a configuration of a fuel management device (workstation) WS which is a part of a coal storage yard operation system and which realizes a coal yard coal placement planning method according to a first embodiment of the present invention. Is. In this figure, reference numeral 1 is a keyboard, and an operator inputs a coal stowage plan and a coal delivery plan. As this loading plan, the date, ship name, coal brand, loading amount (t), etc. are input, and as the payout plan, the date, coal brand, available power generation amount, and coal consumption The amount etc. is input. Reference numeral 2 denotes an input port, which reads the actual coal stock yard status (coal stock yard map information) from the coal stock yard through a monitoring device (not shown) or the like by communication. Reference numeral 3 denotes a RAM, which stores the above-mentioned respective information input through the keyboard 1 and the input port 2.

Reference numeral 4 is a coal storage operation processing unit, which is a keyboard 1
Input information holding buffer BF for recording operation records etc. by
It has R, and performs a coal stock yard allocation correction process described later. Reference numeral 5 denotes a disc, which stores the operation record recorded in the input information holding buffer BFR. Reference numeral 6 denotes a CPU, which controls the above-mentioned units. A CRT 7 displays an input screen for each data, processing results of the coal storage operation processing unit 4 and the CPU 6, and the like.

Next, the processing of the fuel management system WS having the above-mentioned configuration will be described. The dates for the two-week loading / unloading plan and coal allocation plan will be
Explain as a day. First, the processing of the coal stowage / delivery plan and the coal allocation plan will be described with the flow shown in FIG.

First, in step SA1, the CPU
6 retrieves the state of the coal yard as of May 20 (coal yard map information), that is, the final state of the day before (May 19th) from the coal yard not shown by communication through the input port 2 and stores it in the RAM 3. Next, proceeding to step SA2, the CPU 6 causes the CRT 7 to display a stowage plan value input screen or a payout plan value input screen. According to this display screen, the operator inputs the stowage plan value and the payout plan value of May 20 from the keyboard 1 (corresponding to the above-mentioned operation of the coal yard operation). Input data is C via RAM3
It is captured by PU3 and displayed on CRT7.

Thereafter, the process proceeds to step SA3, where the CPU 6
Displays the allocation input screen based on the coal storage map on May 19 on CRT7. According to this display screen, the operator operates the keyboard 1 to plan the coal allocation on May 20 based on the above-mentioned stowage / payout plan. As a result, the coal storage map plan for May 20 is created and stored in the RAM 3. Then, the contents of the operation thus performed are recorded in the input information holding buffer BFR by the coal storage operation processing unit 4 as an operation record. Here, the contents to be recorded are shown below. 1) Setting of loading or unloading 2) Coal brand name 3) Coal amount 4) Which pile in the coal storage plant should be treated 5) Which position in the pile should be treated

Thereafter, the process proceeds to step SA4, where the CPU 6
Determines whether the two-week coal allocation plan has been completed. Since the result of this determination is “NO” here, the process returns to step SA2, and steps SA2 and S
In A3, the plan for the next day, that is, May 21 is similarly performed. Then, the determination in step SA4 is "N
While it is “O”, that is, while the plan for two weeks is not completed, the process returns to step SA2 and the processes of step SA2 and step SA3 are repeated. Then, when the plan for two weeks is completed, the judgment result in step SA4 is "Y
ES ”, and proceeds to step SA5. Then, in step SA5, the coal storage operation processing unit 4 writes the operation record recorded in the input information holding buffer BFR to the disc 5
Write in. Then, the process ends.

According to the coal yard map created as described above, work instructions for May 20 are created, and coal is loaded and discharged based on the work instructions. Then, on the next day (May 21st), the map for May 21st is read out from the coal yard maps created by the above-described processing. However, if the work on May 20 is not carried out according to the work instruction, the actual coal stock map at the time when the work on May 20 is completed and the work on May 20 created by the above-mentioned planning process. There is a quantitative difference from the coal storage map, which is the plan information. Therefore, before the work on May 21, the allocation plan on and after the 21st is corrected. The allocation correction process will be described below with reference to the flow shown in FIG.

First, in step SB1, the CPU 6
Retrieves the state of the coal yard as of May 21 (coal yard map information), that is, the final state of the previous day (May 20) from the coal yard not shown by communication through the input port 2 and stores it in the RAM 3. Next, the process proceeds to step SB2, where the coal storage operation processing unit 4 performs step SA shown in FIG.
The operation record recorded on the disk 5 in 5 is taken into the input information holding buffer BFR.

After that, the process proceeds to step SB3, and the coal storage operation processing unit 4 reads out the operation record taken in the input information holding buffer BFR. Then, in step SB4, it is determined whether the data recorded in the read operation record is “payment” or “payout”. If the result of this determination is that the product is "packing", the process proceeds to step SB5.
Then, in step SB5, with respect to the coal storage map as of May 21, the specified amount of coal of the brand name recorded in the operation record is specified, and the specified position of the specified pile is specified. "Ship" to. If the read operation record data is “payout”, the process proceeds to step SB6, and the coal of the brand name is specified by the specified amount in the coal storage map as of May 21.
"Payout" is performed from the specified position of the specified pile.

When step SB5 or step SB6 is completed, the process proceeds to step SB7, and it is determined whether or not there is a quantitative contradiction when setting the stowage / payment. Here, the quantitative contradiction is, for example, in the case of stowage, where it cannot be stowed in the stowage place recorded in the operation record, and in the case of withdrawal, it is recorded in the operation record. This is the case when the amount of coal in use does not exist. If the above contradiction occurs, the determination result in step SB7 is "Y
ES ”, and the process proceeds to step SB8. Then, in step SB8, the operator is asked to confirm the contradictory point and the operation record is corrected. If it is impossible for the operator to load the amount of coal recorded in the loading place recorded in the operation record as described above, reduce the amount of coal to be loaded, and Modify the operation record according to. When it is impossible to deliver the amount of coal recorded from the delivery place recorded as described above, the amount of coal to be delivered is reduced and the operation record is similarly corrected.

After the above correction, or when the result of the determination in step SB7 is "NO" because there is no quantitative contradiction, the process proceeds to step SB9. Then, in step SB9, the coal storage operation processing unit 4 determines whether all the operation information in the input information holding buffer BFR has been executed, that is, whether the processing for two weeks until June 2 has been completed. If the result of this determination is "NO", the flow proceeds to step SB3, and the processes of steps SB4 to SB8 are repeated. Then, when all the operation records up to June 2 are executed, the determination result in step SB9 becomes “YES”, and the allocation correction process ends.

When the above-mentioned allocation correction is completed, the operator inputs the loading / delivery plan for one day only on June 3, and
The allocation plan for June 3 will be made based on the coal storage map plan for June 2. The above-mentioned allocation correction process is automatically executed every day. Further, by performing the correction as described above and performing the additional work for one day, the operation for one year becomes possible.

Here, in FIG. 4 (a), the coal storage map MP on May 19 when the allocation is not corrected,
The coal storage map MP of May 20 and 21 planned based on it is shown. Further, FIG. 4B shows the coal storage yard map MP on May 19 and the coal yard status after actual work on May 20 when the allocation correction method according to the present embodiment is used for correction. Map MP showing the above, and the coal map MP planned on May 21 based on the map
And indicates. In these figures, the area AR _A shows the coal arranging situation in the pile A, the area AR _B shows the coal arranging situation in the pile B, and the area AR _C shows the coal arranging situation in the pile C. Further, inventory data DT, DT ... Are displayed in each area.

Comparing the situation of the coal stockyard on May 20 shown in FIG. 4 (b) and the plan of the same day shown in FIG. 4 (a),
The inventory data DT of the area AR _A in FIG.
The amount of coal is large by the amount GP. Therefore, 2 shown in FIG.
The zero day coal yard map MP is quantitatively different from the actual coal yard situation. The 21st-day coalyard map MP shown in FIG. 4 (b) is planned based on the situation of the coalyard after the end of the work on the 20th, and thus the quantitative deviation from the actual situation of the coalyard is corrected. Has been done. Therefore, there is no quantitative conflict between the allocation plan of the coal storage yard and the actual allocation.

§2. Second Example In the first example, an allocation operation is performed every day when a coal loading / delivery plan and a coal allocation plan for two weeks are performed. The coal placement planning method according to the second embodiment shows a method of automatically planning when the allocation operation is a repetition of almost the same operation.

FIG. 5 is a flow chart showing the processing of the coal stowage / delivery plan and the coal allocation plan according to the second embodiment. Hereinafter, the day when the plan is carried out will be described as May 20.

First, in step SC1, the CPU
6 retrieves the state of the coal yard as of May 20 (coal yard map information), that is, the final state of the day before (May 19th) from the coal yard not shown by communication through the input port 2 and stores it in the RAM 3. Next, proceeding to step SC2, the CPU 6 displays a stowage plan value input screen or a payout plan value input screen on the CRT 7. According to this display screen, the operator inputs the stowage plan value and the payout plan value of May 20 from the keyboard 1. Input data is RAM
It is taken in by the CPU 3 through the display 3 and displayed on the CRT 7.

Then, the process proceeds to step SC3, where the CPU 6
Displays the allocation input screen based on the coal storage map on May 19 on CRT7. According to this display screen, the operator operates the keyboard 1 to plan the coal allocation on May 20 based on the above-mentioned stowage / payout plan. As a result, the coal storage map plan for May 20 is created and stored in the RAM 3. Then, the CPU 6 records the operation procedure for one day thus performed in the RAM 3 as an operation record.

Next, in step SC4, the allocation input screen for the next day, that is, May 21 is displayed. Then, the process proceeds to step SC5, and it is determined whether the same operation as the operation procedure of the previous day is performed. Here, the operator uses the keyboard 1
If the user specifies that an operation different from the operation procedure of the previous day is performed by operating, the judgment result in step SC5 becomes “NO”, the flow returns to step SC2, and the CRT again.
7 displays the stowed plan value input screen or the payout plan input screen. Then, the operator newly inputs the stowage plan value and the payout plan value on May 21.

On the other hand, when the operator operates the keyboard 1 to instruct to perform the same operation as the operation procedure of the previous day, the judgment result in step SC5 becomes "YES", the process proceeds to step SC6, and is recorded in the RAM 3. Read the operation record of the previous day. Then, in step SC6, the CPU 6 executes coal allocation on the coal storage map on the previous day, that is, on May 20, based on the operation procedure recorded in the operation record. Next, in step SC7, it is determined whether or not a contradiction has occurred as a result of the coal allocation in step SC6. If a contradiction occurs, the determination result in step SC6 is "NO", and the process returns to step SC2 to plan again.

On the other hand, if there is no contradiction as a result of executing the coal allocation in step SC6, step S6
The determination result in C7 is "YES", and step S
Return to C4. Then, on the next day, that is, on May 22, the stowage / delivery plan is started.

As described above, in this embodiment, the operation procedure after that is automatically created based on the record of the operation procedure of the coal allocation plan of the previous day, and the coal allocation plan is performed in a short time. I was able to do it. As a result, not only two weeks, but also a long-term plan can be easily performed, and the invention can be applied to drafting a coal yard operation plan and verifying an entry plan.

§3. Third Example In the above-mentioned coal storage yard, there are "horizontal stacking" and "stacking" as methods for stacking coal by a stacker.
“Horizontal stacking” is a method of stacking coal piles CL having a specified height h in the horizontal direction, as shown in FIG.
"Stacking" is a method of stacking low coal piles CL until they reach a prescribed height h, as shown in FIG. 6 (b). These methods are selected by the operator who operates the stacker in the coal storage yard according to the type of coal, and the work is performed accordingly.

By the way, in the above-described coal allocation plan, when the brand of coal and the height of the coal to be loaded are equal, the coal mine already loaded may be continuously loaded with the coal hill (hereinafter referred to as " Continued loading "). However, when the operator tries to carry out continuous loading, when the coal pile already loaded is the coal pile in the middle of the above-mentioned “stacking” in the situation of the coal stockyard where the CPU 6 takes in from the coal stockyard,
There is a case where the stacking height is different from the coal pile to be newly loaded and an error occurs and the processing is interrupted. Therefore, in this embodiment, the coal allocation plan is adapted to both the "horizontal loading" and the "stacking" methods.

First, FIG. 7 shows an example of a stowed plan value input screen. As shown in this figure, the operator plans, as a loading plan, a loading date DT, a coal brand NM, and a loading amount M.
S, stowage H, and continuation division CC are input. Here, the loading amount MS indicates the amount of coal to be loaded, and the loading height H indicates the height of coal to be loaded. Further, the continuation category CC indicates whether or not the continuous loading is possible, and when it is possible, “continuation” is set as the continuation category CC. In addition, at the bottom of this stowed plan value input screen,
The coal brand names NM, NM, ... And the corresponding coal brand codes CD, CD, ... Are displayed.

Next, FIG. 8 shows an example of an allocation input screen for making a coal allocation plan. In this figure, the area AR _A
Shows the arrangement of coal mountains in pile A, area A
R _B represents a location state of the coal pile in pile B, area AR _C shows the disposition of an coal pile in pile C.
Inventory data DT _A , DT _B , and DT _C are displayed in the areas AR _A , AR _B , and AR _C , respectively. The length L of the inventory data DT _A , DT _B , and DT _C is determined according to the bottom area of the coal pile to be actually loaded. Also, inventory data D
T _A, DT _B, and the inside DT _C, coal brand code C
D, loading date DAT, and inventory ST are displayed.
Further, in the lower part of the screen, an area AR _D in which the coal brand code CD registered in the loading plan value input is displayed and an area AR _E in which the coal brand code CD registered in the payout planned value input is displayed. It is provided.

Here, the operation of the CPU 6 in this embodiment will be described with reference to the flowchart of FIG.
First, in step SD1 of FIG.
If the area AR _D is clicked with the mouse, as shown in,
CPU6 is, coal stocks NM, date DA with the product of the coal mountain corresponding to the coal stock code CD that was displayed in the area AR _D
T, stowage amount MS, stowage height H, continuation section CC, and the like are displayed in the area AR _F , and the cursor CR is displayed.

Here, the operator designates that the coal pile designated as described above is continuously loaded on the coal pile already loaded on the pile B. That is, the operator moves the cursor CR with the mouse and clicks at the position of the inventory data DT _B of the pile B.

Next, in step SD2, the CPU 6
Compares the height of coal piles already loaded on pile B with the loading height H of coal piles to be continuously loaded, and if they are equal,
It is judged that the existing coal mine is loaded by “horizontal loading”, and if different, it is judged that the existing coal mine is loaded by “tiered loading”.

Next, in step SD3, the stock amount ST of the coal pile represented by the stock data DT _B and the loading amount MS of the coal pile to be continuously loaded are added to obtain the total loading amount. .
Then, the process proceeds to step SD4, and the total loading amount obtained in step SD3 and the loading amount H of the coal pile to be continuously loaded.
And the angle of repose, the bottom area with pile of coal piles in pile B is calculated. After that, it advances to step SD5, CPU
6 displays the data DT _B having the length L corresponding to the above-mentioned bottom area with stowage as shown in FIG. 11. Further, the total stowed amount described above is displayed in this data DT _B.

As described above, according to the present embodiment, it is possible to carry out continuous loading even if the already loaded coal piles are in the middle of "stacking".

[0043]

As described above, according to the invention described in claim 1, based on the coal loading plan for the entire coal stockyard and the coal payout plan from the entire coal stockyard for a certain period, the time In addition to creating a coal allocation plan of the coal storage for the fixed period by performing the allocation operation of the coal in the fixed period for the coal allocation situation of the coal storage in, and record the operation procedure in the allocation operation, Each time the date is updated, with respect to the actual coal placement situation of the day before the coal yard, by performing the allocation operation in the fixed period according to the recorded operation procedure, the actual coal placement situation and the coal placement Since the deviation from the plan is detected and the coal allocation plan is corrected based on the detection result, the allocation operation is re-performed after waiting for the input of the stowage plan and the withdrawal plan. It is not required, it is possible to significantly reduce the time required for correction. This has the effect of preventing divergence of the plan and improving the effectiveness of allocation of the coal yard. Further, according to the invention of claim 2, based on the coal loading plan for the entire coal storage yard and the coal delivery plan from the coal storage yard, the allocation of coal to the coal allocation situation of the coal storage yard at that time is allocated. Along with performing the operation, the operation procedure in the allocation operation is recorded, and according to the recorded operation procedure, the allocation operation is performed for the coal allocation situation on and after the next day, so that the coal allocation plan is created. This has the effect of shortening the time required for the coal placement plan, facilitating long-term planning, and being applicable to the drafting of a coal yard operation plan and the verification of an entry plan. Further, according to the invention of claim 3, when the allocation operation is performed with respect to the coal arrangement state of the coal storage yard, the mountain of coal is continuously added to the coal hill arranged at the coal storage yard at that time. When loading, compare the height of the pile of coal arranged in the coal storage yard with the height of the pile of coal continuously loaded, and if the height of the pile of coal is equal, stipulate Select a stacking method that stacks piles of coal in the horizontal direction in the horizontal direction, and if the heights of the coal piles are different, stack the low piles of coal up to the specified height. Select a stowage method, calculate the total stowed amount by summing the stowed amount of coal piles arranged in the coal storage yard and the stowed amount of coal piles to be continuously loaded, The bottom area for loading is calculated from the total loading amount and the height of the pile of coal that is continuously loaded, and the loading method and the bottom area for loading are stored. Since it is displayed on the yard, it is possible to continue to load the coal pile regardless of which of the above-mentioned loading methods is used for the pile of coal placed in the coal storage yard. It will be possible. Therefore, it becomes easy to change the stowage method, and it is possible to cope with the change in the type of coal.
