FIG. 2 is a diagram showing a configuration example of the power generation cost calculation server 100. As shown in FIG. The power generation cost calculation server 100 includes a storage unit 10, an operating personnel actual result calculation unit 20, an apportionment cost calculation unit 30, a power plant total cost calculation unit 40, and a power generation cost calculation unit 50. ing.

The storage unit 10 stores a work order table 11 , an operating personnel record table 12 , an integrated cost table 13 , a power plant cost record table 14 , a power generation record table 15 and a power generation cost record table 16 . FIG. 3 is a diagram showing a configuration example of the work order table 11. As shown in FIG. FIG. 4 is a diagram showing a configuration example of the operating personnel track record table 12. As shown in FIG. FIG. 5 is a diagram showing a configuration example of the integrated cost table 13. As shown in FIG. FIG. 6 is a diagram showing a configuration example of the power plant cost record table 14. As shown in FIG. FIG. 7 is a diagram showing a configuration example of the power generation record table 15. As shown in FIG. FIG. 8 is a diagram showing a configuration example of the actual power generation cost table 16. As shown in FIG. It should be noted that the tables in FIGS. 3 and 4 are examples configured as tables divided for each month. These tables may be constructed so that the contents of the tables can be tabulated on a monthly basis. 3 and 4 should be configured as one table and each table should have an item of "month", which is the aggregate unit, instead of being configured as a table divided by month as in FIGS. 3 and 4. The contents of the table may be aggregated by month.

The work order table 11 can store the contents of work orders generated based on the information input by the operating work input server 200 . For example, as shown in FIG. 3, the work order table 11 stores the contents of each work order as a record associated with the work order number (No). Specifically, in the record associated with the work order number (No), as shown in FIG. Items such as "Item", "Account Belonging", "Subcontractor", and "Account Item" can be included.

A work order is a unit for managing operation work that is necessary for operating a power plant. , are generated and managed in the work order table 11 . Each work order contains multiple items. For example, items representing power plant name, work name, and cost type are included. In the case of the work order table 11 shown in FIG. 3, "subcontracting/direct management", "budget item", "account affiliation", "consignee", and "account item" are included as items representing types of expenses.

Here, the operating work includes maintenance work, construction work, and patrol work. Maintenance work is work other than patrols scheduled in advance on an annual schedule such as periodic repairs and periodic inspections for maintaining the operation of the power plant. Unlike maintenance work, construction work is work that is required due to an unexpected cause such as equipment failure. A patrol work is a patrol work for checking the operation status of equipment.

In the work order table 11, "function" indicates the type of power plant, and for example, values such as water power, wind power, and solar power are entered. The work order table 11 can be managed on a head office basis, and can set work for a plurality of types of power generation facilities under the head office management. With this item of "function", it is possible to extract the work for the hydroelectric power plant among the work for the plurality of types of power generation facilities.

In the work order table 11, the "work name" indicates the type of operation work, and specific "work name" values include, for example, "drainage pump inspection" and "GoV board replacement". is entered.

In the work order table 11, "outsourcing/direct management" indicates whether the work is outsourced or performed by workers from directly managed offices. A value is entered. This item of "outsourced/directly managed" can be used to extract a record when a work order that is "directly managed" is used to calculate the performance of operating personnel.

In the work order table 11, the "budget item" indicates what kind of expense item the work order is included in the budget. is entered.

In the work order table 11, the "account affiliation" indicates to which office the account generated when a work order is generated belongs. For example, a value such as "A office b group" is entered. be done.

In the work order table 11, the "contractor" indicates the consignee when the work is outsourced. .

In the work order table 11, the "account item" indicates the bookkeeping name of the account generated when a work order is generated. be done.

When the completion of the work for the work order is input to the operating personnel record table 12, the operation record, which is the record of the work for each work order, is used to calculate the actual record of the operating personnel for each predetermined period at each power plant. stored as data. The performance of operating personnel indicates the performance of operating personnel determined according to the number of workers actually seconded to each power plant and their working hours in units of a predetermined period at each power plant.

The operation record has items including, for example, "power station name", "function", "work name", "outsourcing/direct management", "account affiliation", "operating personnel", "operating hours", and "remarks". For example, as shown in the operating personnel performance table 12 of FIG. 4, these items can be stored for each work order.

In the operating staff record table 12, "operating staff" indicates the number of workers who perform work for each work order, and for example, the value of the number of workers is input. In the operating personnel record table 12, "operating time" indicates the time required for the work for each work order, and for example, the value of the working time is input.

The operating personnel performance table 12 is referred to when calculating the operating personnel performance for each predetermined period at each power plant. In the operating personnel record table 12 shown in FIG. 4, for the records in which "outsourced/directly managed" is "directly managed", the operation record of each power plant is extracted from the item of "power plant name", and the extracted operation record is aggregated. can do.

The actual number of operating personnel can be aggregated from the "number of operating personnel" and "operating hours" of records extracted for a given power plant. For example, in the case of showing the performance of operating personnel on a monthly basis, if one worker is seconded for the number of days corresponding to half a month, it can be converted to 0.5 workers/month. Although not shown in FIG. 4, the operating personnel performance table 12 may store the number of workers actually seconded to each power plant for each aggregated month as the aggregated operating personnel performance.

The integrated cost table 13 stores the aggregated results of the integrated cost, which is the cost required to collectively manage a plurality of hydroelectric power plants, for each predetermined period. For example, as shown in FIG. 5, in the integrated cost table 13, for the aggregated month, the “general administrative expenses (business office general administrative expenses)” and “taxes and public charges (business expenses)” of the office to which the power plant belongs tax and dues)", the month's "general administrative expenses (head office general administrative expenses)" and "taxes and dues (head office tax and dues)" of the head office are stored in association with each other.

The power plant cost record table 14 stores the cost for each predetermined period required to operate each power plant. These costs include costs that can be accounted for by the power plant alone and costs that cannot be accounted for by the power plant alone. The costs that can be accounted for by the power plant are the costs linked to the power plant, and the costs that cannot be accounted for by the power plant are the costs obtained by proportionally dividing the costs in the integrated cost table of FIG. For example, in the power plant cost performance table 14, the cost performance is stored in association with the aggregation month and the power plant. As shown in FIG. 6, the actual expense can include "account" and "amount".

In the "account items" of the power plant expense record table 14, for example, values such as "repair expenses", "business office general administrative expenses", and "head office taxes and duties" are recorded.

The power generation record table 15 stores the power generation record of each power plant. The actual power generation record indicates the amount of power actually generated at the power plant. For example, as shown in FIG. 7, the power generation record table 15 stores the power generation record in association with the total month and the power plant.

The actual power generation cost table 16 stores the actual power generation cost at each power plant. The actual power generation cost shows how much electricity was actually generated per unit at the power plant. For example, as shown in FIG. 8, the actual power generation cost table 16 stores the actual power generation cost in association with the aggregation month and the power plant.

Returning to FIG. 2, the operating personnel performance calculation unit 20 processes input related to work orders, and indicates the number of workers involved in the operation work of each hydroelectric power plant in units of a predetermined period. Calculate the actual number of operating personnel.

When a new work order is input from the operating work input server 200, the operating personnel performance calculation unit 20 creates a work order by creating a new record in the work order table 11 (see FIG. 3). Further, when the operation work input server 200 inputs the result of executing work at each power plant based on the work order, the operation personnel performance calculation unit 20 selects the target from the records recorded in the work order table 11. The work order record is specified, the work order correction is accepted, and the content is registered as the operation result. The registered operation record is recorded as a new record in the operating personnel record table 12 (see FIG. 4).

The operating staff performance calculation unit 20 can calculate the operating staff performance for each predetermined period based on the operating performance recorded in the operating staff performance table 12 . The calculation of the operating personnel record for each predetermined period may be performed each time the operating personnel record is registered, or may be calculated based on the operating personnel record registered for each predetermined period. The operating staff performance calculation unit 20 may store the calculated operating staff performance in the operating staff performance table 12 .

The operating personnel performance calculation unit 20 can refer to the operating personnel performance table 12 when calculating the operating personnel performance for each predetermined period at each power plant. In the case of the operating personnel record table 12 shown in FIG. 4, for records where "outsourced/directly managed" is "directly managed", the operation record of each power plant is extracted from the item of "power plant name", and the extracted operation record is can be aggregated. What is important here is that among the records recorded in the operating personnel record table 12, all the records whose "power plant name" item is the power plant to be aggregated calculate the operating personnel record for each predetermined period at each power plant. It is not used to Among the records of power plants to be aggregated, only records with "directly managed" in the "outsourced/directly managed" item are used to calculate the operating personnel results.

The operating personnel performance calculation unit 20 can aggregate the operating personnel performance in units of 0.5 hours from the "number of operating personnel" and "operating time" of the records extracted for the power plant to be aggregated. For example, in the case of showing the performance of operating personnel on a monthly basis, if one worker is seconded for 30 minutes, it can be totaled as 0.5 hours/month.

The apportioned cost calculation unit 30 apportions the results of integration costs, which are the costs required when collectively managing a plurality of hydroelectric power plants, based on the results of operating personnel, and calculates the apportioned costs for each hydroelectric power plant. calculate. The cost required to collectively manage multiple hydroelectric power plants is a cost that cannot be calculated for each power plant. Integration costs include, for example, general administrative expenses and taxes and public charges for offices that manage multiple power plants, general administrative expenses and taxes and public charges for headquarters, and the like.

The apportioned cost calculation unit 30 extracts the integrated cost results for the target period from the integrated cost table 13, and obtains the operating personnel track record for the same target period calculated by the operating staff track record calculation unit 20. FIG. The apportionment cost calculation unit 30 apportions the acquired integrated cost result by the operating personnel result for each power plant. In other words, the operating personnel performance of multiple target power plants is totaled, and the ratio of the operating personnel performance of that power plant to the total operating personnel performance (also referred to as the operating personnel performance ratio) is the extracted integration cost performance. By multiplying by For example, from the integrated cost table shown in FIG. 5 , the apportioned cost calculation unit 30 selects “business office general administrative expenses”, “incident office tax and public charges”, and “head office general administrative expenses” of the record of the target period as the integrated costs of the target period. , “head office taxes and dues” are extracted, and these are divided proportionally according to the actual ratio of operating personnel at each power plant, and for each power plant, It is possible to calculate the proportionally divided expenses of

The power plant-by-power plant total cost calculation unit 40 calculates the total cost (power plant cost) of each hydroelectric power plant by adding the apportioned cost of each hydroelectric power plant to the actual cost of the hydroelectric power plant. The cost performance of the hydroelectric power plant is the direct cost required to operate the power plant, and can be recorded for the power plant alone. The total cost of a hydroelectric power plant (power plant cost) is the cost required to operate each power plant, and includes costs that can be recorded for a single power plant and costs that cannot be recorded for a single power plant. The power plant-by-power total cost calculation unit 40 adds up the apportioned cost calculated by the apportioned cost calculation unit 30 and the cost accounted for each power plant, and obtains the actual power plant cost as the actual total cost for each power plant. Store in table 14.

The power generation cost calculation unit 50 calculates the power generation cost at each hydroelectric power station based on the total cost at each hydroelectric power station and the power generation record at each hydroelectric power station. The power generation cost calculator 50 extracts the total cost for each power plant stored in the power plant cost performance table 14 and extracts the power generation performance for each power plant stored in the power generation performance table 15 . The power generation cost calculator 50 can further calculate the actual power generation cost by dividing the extracted total cost for each power plant by the actual power generation performance of the same extracted power plant. The power generation cost calculator 50 can store the calculated power generation cost performance in the power generation cost performance table 16 .

The operating work input server 200 is communicably connected to the power generation cost calculation server 100 of the hydroelectric power plant and performs input regarding work orders. FIG. 9 is a diagram showing a display example of work orders. The work order is for managing the work assigned by the overall manager in the system in order to allocate the work to the workers. A work order includes items such as “power plant name”, “function”, “work name”, “subcontractor/direct management”, “budget item”, “account affiliation”, “consignee”, and “account item”. ing. The work order items can be set according to the contents of the items stored in the work order table 11 of FIG. As shown in FIG. 9, the contents are entered in fields corresponding to each item included in the work order.

The work order input server 200 displays the work order input form shown in FIG. 9 and prompts the user to input, thereby completing the input regarding the work order.

In addition, in the working work input server 200, similar to the work order of FIG. 9, items corresponding to the items of the working staff record table 12 shown in FIG. 4 are displayed, and when the work set in the work order is completed, The user may be prompted to enter the performance of the work.

The management index management server 300 can acquire the actual power generation cost calculated by the power generation cost calculator 50 and stored in the actual power generation cost table 16 and display it as a management index. When displaying, the efficiency of the power plant can be compared more clearly by comparing with the power generation unit price at which the power is actually traded.

Next, the operation of the power generation cost calculation system for hydroelectric power plants described above will be described. First, the operation from work order generation to registration will be described. FIG. 10 is a diagram showing processing from work order generation to registration. First, when a new work is input to the operating work input server 200, the operating personnel performance calculation unit 20 of the power generation cost calculation server 100 generates a work order (step S11).

After that, when the worker completes the work in accordance with the generated work order, the operation work input server 200 receives the input of the work results for the generated work order (step S12). The input of the actual results can be accepted by inputting the contents of the work actually performed based on the generated work order as the actual operational results in the operation work input server 200 . The contents of the work actually performed can be input according to the items of the operating personnel record table 12 .

When the operating work input server 200 receives the input of the actual results corresponding to the work order, the operating personnel actual result calculation unit 20 adds the contents input in step S12 to the work order generated and stored in the work order table 11. It is linked and registered in the operating personnel record table 12 as the operation record (step S13). When registering the operation results, the operating personnel performance calculation unit 20 may calculate the operation personnel results and update the operation personnel performance table 12 as necessary.

Next, the power generation cost calculation operation that is executed at a predetermined timing after the operating personnel performance is calculated based on the operating performance registered by the operation shown in FIG. 10 and the operating personnel performance table 12 is updated will be described. . FIG. 11 is a flowchart illustrating an example of a power generation cost calculation process.

First, the apportionment cost calculation unit 30 acquires the actual operating personnel performance of the power plant that is the target of the power generation cost calculation process from the operating personnel performance table 12 (step S21), and apportions the integrated cost for the target period from the integrated cost table 13. It is acquired as the target expense (step S22). The apportioned cost calculation unit 30 apportions the acquired cost to be apportioned based on the performance of the operating personnel to calculate the apportioned cost (step S23). Note that the order of the processes in steps S21 and S22 may be reversed.

After the apportioned costs are calculated in step S23, the total cost calculation unit by power plant 40 adds up the costs recorded as the actual costs of the power plants to be calculated and the apportioned costs calculated in step S23. Then, the total cost for each power plant in the target period for the target power plant is calculated (step S24).

After the total cost for each power plant is calculated in step S24, the power generation cost calculation unit 50 acquires the power generation performance of the target power plant for the target period from the power generation performance table 15 (step S25).

The power generation cost calculator 50 can calculate the power generation cost of the target power plant by dividing the total cost calculated in step S24 by the actual power generation record acquired in step S25.

As described above, according to the hydroelectric power plant power generation cost calculation system including the hydroelectric power plant power generation cost calculation server of the present embodiment, the power generation cost in the hydroelectric power plant can be calculated.
