Description

  The present invention is a power receiving / transforming equipment system that supports the design of an in-house power receiving / transforming equipment system at the initial stage while taking in the requests of customers (individuals, company-owned buildings, power supply equipment installation companies or designers of factories, etc.). The present invention relates to a design evaluation support system and a design evaluation support method thereof.

  2. Description of the Related Art In recent years, demand for high-quality substation equipment systems has increased with the rapid increase in business processing using the Internet and network computers. The reason for this is that if a failure occurs in the power receiving / transforming equipment system, the operations of all the organizations in the enterprise may stagnate and stop, resulting in immeasurable damage.

  As a measure to improve the quality of substation equipment systems, due to recent technological advances, UPS (uninterruptible power supply equipment) is the first, and many quality compensation such as instantaneous voltage drop compensator, power generation equipment, harmonic filter, active filter, etc. Equipment equipment has been developed. However, it is not possible to maintain a high-quality power supply facility simply by combining such power receiving / transforming equipment, and it is necessary to consider many other factors (life cycle cost, local power outage situation, etc.).

  For installation companies of substation equipment systems, maintenance of power supply quality = sound operation of load equipment = stable continuation of corporate activities is essential, and if the quality of power supply equipment cannot be maintained, it is a stable company Activities cannot be carried out, and losses such as opportunity loss and yield must be recorded.

  Therefore, when building a power receiving / transforming equipment system, visualize the relationship between initial investment and risk (loss due to power failure, momentary power failure, frequency abnormality, equipment failure, etc.), and select an appropriate power receiving / transforming equipment. Is desirable.

  By the way, in recent years, a plurality of distributed power plans that take into consideration the heat demand and power demand in the power system target area (for example, in units of cities and towns and villages) have been created, and a power supply arrangement plan suitable for the target area is selected from among them. There has been proposed a design evaluation method for obtaining a power system configuration plan and a power quality plan in accordance with an arrangement plan, and comparing and evaluating the environmental performance and economic efficiency of each plan (Patent Document 1).

Next, the operation of the design evaluation support system as described above will be described.
In summary, the present invention has the following four basic concepts of the operation of the design evaluation support system.
The first is to virtually construct a system model consisting of a combination of architecture (system configuration, system) selected for the power receiving / transforming equipment system and applicable equipment selected according to the specifications of the equipment constituting the architecture. At the same time, the model is displayed as a visualized image so that it can be understood by a specific hardware image.

The second is to obtain initial costs such as equipment and construction costs for the model.
The third is to simulate the reliability of the model and determine the operating costs including fault repair.

  The fourth is to obtain cost-effectiveness for the model in consideration of the life cycle including the operation period and income.

  Based on the above situation, prepare multiple models with different basic architecture for the model to be built, or change the architecture of the model that was prepared first and the specifications of the equipment, so that multiple models and modifications The purpose is to examine the cost effectiveness of each model by comparison.

(1) Operation of the design unit 4A of the power receiving / transforming equipment system (see the flowchart in FIG. 7).

  In the power receiving / transforming equipment system design unit 4A, necessary items for the system configuration and the applied device are selected, and a model of the power receiving / transforming equipment system to be examined is created, in other words, virtually constructed.

  First, when a design support person inputs a power receiving / transforming equipment system design instruction through the input unit 1, the design evaluation support system is activated to determine that the design instruction of the power receiving / transforming equipment system (S1). The utility program pa is read, and the power receiving / transforming facility system design unit 4A starts executing a predetermined procedure.

  That is, when the power receiving / transforming facility system design unit 4A determines that the design instruction of the power receiving / transforming facility system is in accordance with a predetermined order from the power receiving / transforming facility system design area 2a of the database 2, first, a selection item image file related to the system configuration is selected. 2 is displayed on the display unit 5 (S2), and selection of one item from the plurality of selection items is prompted (S3).

  Here, when the received voltage 66KV indicated by the dotted frame in the figure is clicked from among a plurality of selection items, “66kV” is registered in association with the received voltage item in the management table 2ac of FIG. 5 (S4). Thereafter, unless an instruction for completion of system configuration item selection such as an “END” command is input from the input unit 1, it is determined that the item selection is not completed (S5), and the process returns to step S2 to automatically set the next rating. The short-time current selection item image file is read, and the rated short-time current selection item image G2 shown in FIG. 2 is displayed on the display unit 5 (S2), and the user is prompted to select one item from the plurality of selection items. (S3). Here, when 31.5 kVA of the rated short-time current indicated by the dotted frame in the figure is clicked from among a plurality of selection items, “31.5 kVA” is registered in association with the rated short-time current item of the management table 2ac in FIG. (S4).

  Thereafter, the selection item images G3 to G12 are similarly displayed on the display unit 5 in the order (S2), and 11 selection items are selected. However, in the selection item images G6, G9, and G10, the designer inputs a predetermined value according to the message of the corresponding image. For example, for the impedance which is one item of the selection item image G6, the message “Generally about 4 to 15%” is displayed. Therefore, in consideration of past experience, knowledge, etc., “15%” is set in the message range. Input and register in the management table 2ac.

  Then, in step S4, all the selection item images G1 to G12 of the system configuration are displayed, and one item is selected or a predetermined value is input, and when the system configuration item selection from the input unit 1 is completed. Under the input instruction, it is determined that the selection of the system configuration item is completed (S5), and the selection item images G21 to G25 relating to the next system application device are sequentially displayed to select one item (S6 to S9).

  The selection item image related to the system-applied device is selected based on the input instruction for completion of the selection of the system configuration item from the input unit 1. For example, the number of system configuration selection items is set in advance in the memory counter. Every time an image is displayed, it counts down. When the memory counter reaches “0” without receiving an input instruction for completion of system configuration item selection from the input unit 1, the process automatically proceeds to the next step S6 to apply the system. The selection item images G21 to G25 related to the devices may be sequentially displayed so that one item is selected.

  At this time, when a model image file address exists in the management table 2ac of the database 2 continuously with one selection item among the selection item images G1 to G12 and G21 to G25, it is associated with the corresponding selection item of the management table 2ac. Corresponding model image file addresses ADa to ADg21 to ADg25 are registered.

  When it is determined that the applicable device item selection is completed by inputting the “END” command from the input unit 1 (S9), the substation equipment system design area 2a of the database 2 based on the model image file address of the management table ac. The system configuration related to the power receiving method, power distribution method, and model image files 2aa,... (Only a part shown in FIG. 4) of a plurality of types of system applied devices are sequentially read out and image editing including CAD design software is performed. Using the software pd, the editing process is executed on the display image data storage unit 6 to virtually construct the power receiving / transforming equipment system and display it on the display unit 5 (S10).

  FIG. 8 is an image of the system diagram of the power receiving / transforming equipment system. FIG. 8 shows a system configuration such as a power receiving method (A), a transformer (B), a circuit breaker (C), a transformer (D), a power distribution method (E), (F), and a generator facility (G). 1 represents a system diagram of a power receiving / transforming equipment system that is a combination of a system application device.

  8 is associated with FIG. 2 and FIG. 3, and the portion corresponding to (A) in FIG. 8 corresponds to the portion (A) in FIG. 2, and the portion corresponding to (A) in FIG. This corresponds to part (a) of 3.

  That is, when one item is selected from each of the selection item images G1 to G5, the model images stored in the model image file address ADa connected to the items are combined, and the power receiving method corresponding to (A) in FIG. A model image (A) of the system diagram of the system configuration is created.

  Subsequently, by inputting a necessary value in the selection item image G6, the model image file 2ab of the transformer corresponding to the number of banks is read, and a system diagram of the system configuration around the transformer corresponding to FIG. Model image (B) is created.

  Similarly, one item is selected from the selection item images G7 (corresponding to (C) here) to G12 (here corresponding to (G)) in FIG. The model image file address of each successive system configuration, for example, ADc for the selection item image creation G7 is registered in the management table 2ac. Then, the corresponding model image files 2aa to 2ag are read based on the model image file addresses ADa to ADg of the management table 2ac, and the model images (A) to (G) of (A) to (G) are read as shown in FIG. Virtually build a substation equipment system that combines

  Then, as described above, the entire system diagram for visualizing the virtually constructed power receiving / transforming equipment system can be displayed on the display unit 5.

  In addition, when one item is selected from the selection item images G21 to G25, it represents that the application device of the item selected in the model images (A), (B), and (E) is used. In addition, a substation equipment system model (here, system model # 1) in which a model image (d) of a phase advance capacitor is inserted for each branch line, for example, from a model image file address connected to an applicable device is assumed to be virtual. Can be built.

  For example, when “STORE: M # 1” is input from the input unit 1 as a recording command, various data related to the building elements (configuration and applicable devices, specifications, etc.) of the virtually built system model # 1 It is named as M # 1 "and is written and stored in the management table 2ac.

  Further, when an instruction to calculate the initial cost is input from the input unit 1 while the image image of the power receiving / transforming equipment system is being displayed on the display unit 5 (S11), it is linked to the applicable device and stored in the management table 2ac. An initial cost calculation process is executed based on the cost data.

  This initial cost calculation process is stored in the crossover area of the initial cost table 2ad shown in FIG. 6 based on the selection items of the system configuration registered in the management table 2ac and the system application device by the both cost programs pca and pcb. Each cost such as equipment cost and construction cost is sequentially read out, for example, sequentially written in the necessary areas of the cost items of the management table 2ac, and these costs are accumulated to obtain the initial cost of the power receiving / transforming equipment system. The data is additionally written and stored in the data of M # 1, and displayed on the display unit 5 (S13).

  After displaying the image and initial cost of the power receiving / transforming equipment system on the display unit 5 as described above, it is determined whether or not a change instruction is input from the input unit 1 by, for example, “REV” command input (S14). For example, when “COST” is input after “REV” and it is determined that a change instruction is input from the relationship with the customer's budget, it is determined whether the system configuration or the system application device (S15). .

  For example, when the system configuration change is designated by inputting “CONFIG” after “COST”, the process proceeds to step S 2, the necessary selection item images are read, the selection is sequentially changed, Perform cost calculation.

  As a result, for example, when the change scale is large and stored as another system model # 2, it is additionally stored in the management table 2ac as “M # 2” by the storage command.

  On the other hand, when “MODEL” is input after “COST”, when a change in the selection of the system-applied device is instructed, the process proceeds to step S6, where necessary selection item images are read, and selection is sequentially performed. Calculate the cost again. As a result, if the change is small and stored as a change or correction of the system model # 1, it is additionally stored in the management table 2ac as “M # 1-a” by the storage command.

  In the embodiment, a plurality of selection item images G1 to G12 related to the system configuration of the system model (# 2) of the power receiving / transforming equipment system and a plurality of selection item images G21 to G25 related to the system application device are predetermined. Each item is displayed individually according to the order, and the user is prompted to select or input the required item from each selection item image. However, multiple selection item images are grouped for each system configuration and each system application device. The items may be displayed in a lump, and required items may be sequentially selected from the selection item images, or input may be prompted.

  Further, the plurality of selection item images G1 to G12 and G21 to G25 are not limited to those shown in FIGS. 2 and 3, and images of necessary selection items are arbitrarily created in advance and sequentially displayed in a predetermined order. Alternatively, any configuration may be used as long as it is a collective display.

(2) Operation of Risk Evaluation Unit 4B An example of processing by the risk evaluation unit 4B of the facility design evaluation processing unit 4 will be described with reference to the flowchart of FIG.
Based on the risk evaluation program pb (risk evaluation simulation tool), for example, the risk evaluation unit 4B calculates a failure probability that becomes an assumed risk for each unit output trunk of the power receiving / transforming facility system for the system model # 2 described above, Executes the visualization process. Here, the failure probability is, for example, an approximate system unit period (for example, an average period of power failure including instantaneous interruption of the power receiving system and an average life period of each applicable device (equipment equipment) of the power receiving / transforming equipment system) This is expressed as the probability (ratio) of failure during the expected operation period (for example, 30 years) of the power receiving / transforming facility system every 5 years.

  The risk evaluation unit 4B is based on the failure probability instruction by the design supporter from the input unit 1 (S21), and in accordance with the risk evaluation program, the substation facility system design unit 4A selected and determined by the substation facility system design unit 4A. The image is read out and displayed on the display unit 5 (S22).

  Thereafter, for each unit output trunk line (for example, a power receiving line), the past power failure occurrence frequency including the instantaneous interruption of each system application device and the commercial system in the installation area, that is, failure probability data is extracted from the risk evaluation area 2b of the database 2. For example, since the commercial system catches it as one failure occurrence element (hereinafter also including the power receiving / transforming equipment system), the failure probability is obtained (S23). Since this failure probability is one of the failure rate calculations for the entire system, it is stored in an appropriate area of the database 2.

  At this time, if necessary, the horizontal axis represents the period (number of years), the vertical axis represents the failure probability (0.0 to 1.0 (100%)), and every 5 years, which is the unit period of the power receiving / transforming equipment system, The failure probability of the commercial system is displayed in a window as a line or bar graph.

  Subsequently, it is determined whether a private generator is added in the image of the power receiving / transforming equipment system (S24). If it is determined that the private generator is not added, the failure probability of the private generator is not calculated (S25). The average failure time and the average recovery time stored in the risk evaluation area 2b of the database 2 over the approximate system operation period with respect to the average lifetime of the applied equipment (each receiving / transforming equipment) of the receiving / transforming equipment system # 2 The failure probability is obtained for each system application device (S26), and stored in an appropriate area of the database 2 as a sequential function. At this time, if necessary, the obtained failure probability may be displayed in a window using a line or bar graph.

  Further, it is determined whether or not another system application device is used in the image of the selected power receiving / transforming equipment system (S27), and if it is used, the failure probability of the application device is obtained in the same manner. To go.

  Then, after determining the failure probabilities of all necessary commercial systems, private generators, and each system application device, commercial systems stored in advance for the failure probabilities of each commercial system, generator, and each system application device Then, the self-generator and the weight function for each applied device are multiplied to obtain the total failure probability and the cumulative failure rate for each predetermined period in the power receiving / transforming equipment system, which are visualized and displayed on the display unit 5 (S28).

  The total failure probability data is additionally written and stored in, for example, “M # 2” stored in the management table 2ac.

  For visual display, assign a weight function to each failure system, the importance of the device, and each commercial system, generator, and applicable device, and set the total failure probability in the range of 0.0 to 1.0, or The failure probability × weighting function for each commercial system, generator, and applicable device may be added sequentially in a stacked manner and visualized on the display unit 5.

  In the total failure probability calculation, the portion with the highest failure probability becomes a bottleneck in the entire system in the system application device or the system component portion combining them. Therefore, in general, the replacement timing and the maintenance inspection period are set as standard values for these system-applied devices based on empirical rules and maintenance data. These values are stored in the management table 2ac together with the failure probability data.

  During the visualization process, the color of the model image that becomes the most bottleneck in the failure rate calculation unit on the system configuration corresponding to the above replacement timing etc. is changed from the other part, or a warning is displayed such as blinking For reliability, it may be possible to promote examination of applicable devices and configurations.

  Further, when the margin for the standard maintenance / inspection period is less than the standard maintenance / inspection period, a similar warning may be displayed to encourage the examination of the configuration.

  Note that the risk assessment area 2b of the database 2 stores the power failure continuation time of the commercial system, etc., and the average recovery time at the time of failure of each power receiving / transforming device (including the transformer). If the amount of damage to the time and the average recovery time of each power receiving / transforming device (including transformer) is linked, the approximate amount of damage is accumulated, and the failure probability and the amount of damage are visualized on the display unit 5. (S29).

(3) Operation of Cost Effectiveness Evaluation Unit 4C The cost effectiveness evaluation unit 4C of the facility design system evaluation processing unit 4 will be described.

  The cost-effectiveness evaluation unit 4C evaluates the cost-effectiveness of each system application device including the power receiving / transforming equipment system # 2 in accordance with the cost-effectiveness evaluation program pca, in other words, in the power receiving / transforming equipment system. A process of calculating the life cycle cost of expenditure (negative cost) and income is performed.

  As shown in FIG. 10, the cost-effectiveness evaluation unit 4C includes an initial cost processing unit 4C1, an operation cost processing unit 4C2, a damage cost processing unit 4C3, an income processing unit 4C4, and an overall processing unit 4C5.

  The initial cost processing unit 4C1 is a processing unit that calculates a newly expected initial cost in addition to the above-described initial cost obtained from the virtually constructed power receiving / transforming equipment system.

  The operation cost processing means 4C2 is a process for calculating various operation costs such as consumables, repair charges for failures based on the above-described failure probabilities, labor costs, and the like that are required in the operation stage of the power receiving / transforming equipment system. . The damage cost processing means 4C3 is a processing means for calculating damage costs related to accidents and effects. The income processing unit 4C4 is a processing unit that calculates the total cost in consideration of power sales related to the use of a private power generator or the like, or reduction of the cost that should be paid. The total processing unit 4C5 is a processing unit that compares the costs of a plurality of power receiving / transforming equipment systems that are virtually constructed by changing the system configuration, applied devices, and operating conditions.

  Next, an example of processing by the cost effectiveness evaluation unit 4C of the facility design system evaluation processing unit 4 will be described with reference to FIGS.

  For example, when a cost evaluation instruction such as “EST: M # 2” is input from the input unit 1 to the power receiving / transforming facility system # 2 (S31), according to the cost-effectiveness evaluation program pca, The initial cost processing means 4C1 is executed.

  The initial cost processing means 4C1 determines whether or not to display the cost list image by reading the designation from the input unit 1 (S32), and when determining that the cost list image is displayed based on the setting of the flag or the like in advance, 11 is displayed on the display unit 5 (S33). In this case, it is executed by a predetermined cost calculation procedure from the input unit 1. For example, there is a method in which a cost calculation factor item that is not displayed in the model image or system diagram is displayed on the display unit 5 (not shown), and an operator selects and designates it or inputs required parameters.

  On the contrary, when it is determined not to display or after displaying the cost list image in step S33, initial cost processing is performed.

  In this initial cost processing, for example, all costs shown in FIG. 5 calculated at the time of design of the selected power receiving / transforming equipment system are extracted from the management table 2ac and integrated, or when the initial cost has already been calculated. The total initial cost is extracted (S34).

  Furthermore, items such as system configuration requested by the customer, applicable equipment, construction, etc. are input from the input unit 1 by, for example, inputting data into necessary items on the input screen that is displayed on the display unit 5 and scheduled. To do. Then, the initial cost processing unit 4C1 compares the input request item with the extracted data. It is checked whether there is a new event that is not included in the budget at the time of receiving / transforming equipment design, for example, items such as seismic reinforcement (S35). If there is, a new cost is input from the input unit 1 (S36), and the cost At the same time as writing to the cost area of the list image data, integration is performed in step S34, and after obtaining the total initial cost aaa including the newly added portion, the initial cost = aaa is displayed on the display unit 5 (S37).

  Subsequently, the operation cost processing means 4C2 is executed by the cost integration program pcb. The operation cost processing means 4C2 is based on the data related to the operation cost stored in the cost-effectiveness evaluation area 2c of the database 2 and the data inputted from the input unit 1 by the design supporter as necessary, etc. Costs related to regular maintenance and maintenance, fuel costs for system operation, property tax, etc. are sequentially determined over the operation period.

  These operating costs also include consumables, labor costs, routine maintenance, and repair replacement estimates based on risk assessment. Naturally, it is a factor that is greatly influenced by the system configuration, selection and combination of system-applied equipment, regular maintenance standards, etc.

  And it writes in the expense area of cost list image data, integrates these individual costs, and calculates total operation cost bbb (S38, S39). Then, the total operating cost = bbb and the like are displayed on the display unit 5 (S40). If a display item such as a cost associated with a specific system configuration and the number of periodic inspections corresponding thereto is designated in advance by a command from the input unit 1, for example, the operation cost for the designated item is displayed on the display unit 5 To display. Information corresponding to this designation may be named, for example, M # 1r and stored in the management table 2ac.

  Furthermore, similarly, cost estimation in the damage expense processing means 4C3 and the income processing means 4C4 is executed by the cost integration program pcb.

  The damage expense processing means 4C3 converts the negative factor of the absence of work accidents and social negative factors for the accident into costs, writes them in the cost area of the cost list image data, adds these individual costs, and calculates the total damage cost ccc. The total damage cost = ccc is displayed on the display unit 5 (S43).

  Furthermore, as mentioned above, when the target power receiving / transforming equipment system has power generation by solar power generation, heat cycle processing, etc., or is connected to energy supply means, it is not an expenditure item but an income item for cost calculation. Will be included.

  Therefore, the income processing means 4C4 calculates the income for each detailed item in FIG. 7, writes it in the expense area of the cost list image data, adds these individual costs and calculates the total income ddd (S44, S45), Total revenue = ddd is displayed on the display unit 5 (S46).

  Thereafter, the life cycle cost is calculated from the negative cost and income (S47), and after writing in the cost list image data, the life cycle cost is displayed on the display unit 5 or the cost list image data is displayed. If not, cost list image data is displayed (S48).

  In calculating the life cycle cost, for example, in addition to using the statutory depreciation period of the equipment, a period setting related to the calculation such as a shorter period or a longer period may be input from the input unit 1.

  The final result of integrating these cost factors is additionally written and stored as total cost data “M # 2c” of the power receiving / transforming equipment system # 2 in the management table 2ac.

  The above procedure can be executed, for example, for the above-described power receiving / transforming equipment system # 2 or the modified power receiving / transforming equipment system M # 1-a. By making necessary parameters, data, and selection specifications for system configuration factors such as system configuration and applicable equipment specifications from the input unit 1, virtual construction is performed while changing models while cutting and trying against costs. On the other hand, the data of the above various simulation results are named and stored as “M # 1s”, “M # 1-as”,..., “M # 2s”, “M # 2-ns”.

  Then, by inputting a predetermined command from the input unit 1 and comparing them again, it is possible to present the best solution to the customer request and to proceed with the integrated examination while cooperating with the customer. .

(4) Complex multiple cost evaluation
Next, the design evaluation support system executes the comprehensive processing means 4C5.
Hereinafter, a method for ranking and evaluating the models according to some cost comparison reference distinction by the comprehensive processing means 4C5 will be described.

  The comprehensive processing means 4C5 extracts, compares, and further edits the data of the plurality of simulation results described above. For example, when a command “COST: LANK: T” is input, the total cost data M # 1s to M # 2-ns are arranged on the display unit 5 in the order of low cost.

  Further, when extracting a model with a low initial cost, for example, it operates with a command such as “COST: LANK: T”.

  Similarly, the total processing means 4C5 is a means for processing a function of displaying and outputting in accordance with the order of cost in accordance with various types of cost comparison criteria such as operation costs and repair costs.

For example, in the set operation period,
A: The trial calculation models are arranged in order of models with the lowest total cost.
B: Arrange in order of models with low initial cost.
C: Arrange in order of model with the lowest operating cost.
D: Arrange in the order of models with a low failure probability in a predetermined number of models, further compare the total cost, and rearrange in the order of the lowest total cost.
E: Arrange in the order of the models with the lowest total cost among the predetermined number of models in the trial calculation model, and further rearrange in the order of the models with the lower probability of failure.

  The total processing means 4C5 performs cost comparison in a multidimensional manner using various composite combinations, outputs model ranks, and displays them on the display unit 5.

(5) Modeling support
Furthermore, in the above embodiment, the system configuration is virtually constructed by accumulating individual factors (elements), in other words, a model of the power receiving / transforming equipment system is created, but the comprehensive processing means 4C5 is as follows. Provide an advisable review process.

  In an actual power receiving / transforming equipment system, there is a certain common model for each business scale and application. Therefore, for example, a base model image that serves as a starting point is prepared, such as a business center with about 100 employees, or a plant facility with a 24-hour operation with a scale of 500 people, and these model images are read out and displayed. 5 is displayed. Then, change data may be input to the displayed model image while changing the input portion 1 while appropriately indicating the change location.

  For example, in the initial stage, a business form selection screen prepared in advance is displayed, and a list of business office models as described above is displayed. Then, it is assumed that a 500-person plant is selected and input from the operator as a model. Upon receiving this input, the facility design system evaluation processing unit 4 displays a system diagram based on a base model corresponding to FIG. 8 corresponding to a plant model of 500 persons from the management table 2ac.

  As a matter of course, model data up to the total cost is stored in the management table 2ac as in the system diagram for the base model, and the change correction process is executed based on this model data.

  Corresponding to FIG. 8, the system configuration selection and application device selection item images in FIG. 2 are prepared in association with each other. In this selection item image, for example, a configuration or application device selected as a default or recommendation candidate from several candidates prepared for general use is highlighted. This display may be a method in which an alternative candidate such as the next point is changed depending on whether the color is changed or displayed smaller.

  Then, for example, when the mouse pointer is moved to the transformer marked with No. 1 TR in (B) (A) of FIG. 8, the screen of FIG. 3 is switched, and the gas-insulated transformer in the (A) part of FIG. It is displayed in reverse video. If you want to change to an oil-filled transformer that is cheaper than a gas-insulated transformer, place the pointer on the oil-filled transformer and click the mouse.

  Here, a change click is notified to the integrated processing means 4C5 from the input unit 1 which is a mouse. The comprehensive processing means 4C5 transfers the new applied equipment “oil-filled transformer” to the power receiving / transforming facility system design unit 4A and the risk evaluation unit 4B, and instructs recalculation relating to the failure rate and various costs.

  Similarly, it repeats similarly about another system application apparatus and a structure if necessary. When the total cost is obtained, for example, it is written and stored in the management table 2ac as model X # 1.

  Further, if it is desired to make further changes to the model X # 1, the work and processing procedure for the changed model similar to the above may be advanced. As a result, since the selection work is prepared in advance, the time and labor required for model creation can be greatly reduced.

  Furthermore, since changes are made according to the application site based on the standard system configuration, both the customer and the design supporter can effectively utilize the existing knowledge and have a concrete image of the examination result system. There is an effect that is easy to do.

  Although the embodiment described above is described as a design evaluation support system for a power receiving / transforming equipment system, a series of processing procedures of the system can be regarded as a design evaluation support method and applied to the power receiving / transformation equipment system. Needless to say.

  According to the embodiment as described above, while sequentially selecting according to the customer's request from the system configuration equipment such as a plurality of types of power receiving systems, power distribution systems, etc. and power receiving / transforming equipment including transformers, Corresponding model image data is connected and the image of the power receiving / transforming equipment system is virtually constructed and visualized on the display unit 5, so that not only the outline of the power receiving / transforming equipment system can be immediately presented to the customer, but also the initial request of the customer It is possible to provide a substation equipment system that can be convinced while considering costs.

  In addition, for the virtually constructed power receiving / transforming equipment system, the failure probability for each predetermined period in the future is obtained and the total failure probability of the power receiving / transforming equipment system is visualized and displayed. At the same time, customers can be assured that they can operate the power receiving / transforming equipment system stably.

  In addition, the initial cost, operational cost, damage cost and revenue life cycle cost of the virtually constructed substation equipment system, the total cost processing of the model by ranking and comparing and evaluating the model by distinguishing several cost comparison criteria, visualization display Therefore, the cost-effective relationship can be easily presented to the customer.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, a database 2 is installed on the network, and a system configuration and each selection item image of the system application device, a plurality of types of power receiving methods, a system configuration related to a distribution method, and model images of a plurality of types of system application devices are extracted from the database 2 Or necessary data may be sequentially stored in the management table 2ac.
