Description

The present invention relates to a reservation right contract system and a reservation right contract method.

Independent power producers (Independent Power Producer operators, hereinafter referred to as "IPP operators") are operators that own power generation facilities for selling electricity. IPP operators are privately owned companies and communities such as small energy producers, and are companies that supply surplus energy to the power system without any concerns in the energy industry.

Consider the case where a fire accident or the like occurs in the main transformer of the power generation facility managed by such an IPP operator. The main transformer is connected to the main engine such as a generator by a main circuit, and in the unlikely event of a failure, the power generation equipment cannot supply electric power. In recent years, efforts to separate power transmission and distribution have been progressing in each country, so in the event of an accident in the main transformer, other systems may not be available. In such a case, it takes time to manufacture a substitute transformer, and a large amount of loss occurs during the period when this power generation facility cannot operate.

In order to avoid such a situation, it is conceivable that each IPP operator maintains and stores the spare equipment of the main transformer. As a result, the IPP operator can significantly reduce the business risk. However, since spare equipment for main transformers is expensive, maintenance and storage of spare equipment by IPP operators may cause financial deterioration such as ROA (return on assets) and cash flow. is there.

Therefore, for example, it is considered that a leasing company or the like maintains and stores the spare equipment of the main transformer and contracts the reservation right of the stored spare equipment with each IPP business operator. As a result, each IPP operator can promptly procure the spare equipment of the transformer in the event of an accident without having to maintain and store the spare equipment of the main transformer by itself.

An example of a business scheme similar to this is described in Patent Document 1. In Patent Document 1, inventory management and delivery so that the supplier bears the execution and responsibility of inventory management to streamline the inventory management of the customer and the supplier, and eliminate waste to secure profits for both parties. The system for providing the advance inventory guarantee service and its method are described.

Japanese Unexamined Patent Publication No. 2004-338926

The invention described in Patent Document 1 cannot know the period until the goods are procured from the viewpoint of the customer to whom the product is delivered.

Therefore, it is an object of the present invention to specify the period until the spare parts are delivered to the customer in the reservation right contract system and the reservation right contract method.

In order to solve the above-mentioned problems, the reservation right contract system of the present invention has a reservation right for spare parts for replacing a device included in a site operated by a business operator with a issuing unit that issues the reservation right to the business operator. When the replacement request of the device is obtained from the business operator having the reservation right, the confirmation unit for confirming the inventory of the spare parts and the manufacturing company set the replenishment delivery date of the new spare parts when the spare parts are not in stock. It is characterized by including an acquisition unit acquired from the above and a delivery date calculation unit for calculating the period until the spare parts are delivered to the site of the business operator.

The reservation right contract method of the present invention has a step of issuing a reservation right for spare parts for replacing a device included in a site operated by the business operator to the business operator, and the reservation right. When the replacement request of the device is obtained from the business operator, the step of checking the inventory of the spare part, the step of obtaining the replenishment delivery date of the new spare part from the manufacturing company, and the delivery of the spare part to the site of the business operator. It is characterized by the step of calculating the period until and execution of.

Hereinafter, a mode for carrying out the present invention will be described in detail with reference to each figure.
FIG. 1 is a diagram showing a business scheme of the present embodiment.
Manufacturing company 6 sells transformers. The leasing company 5 purchases a transformer from the manufacturing company 6 and owns it as inventory (S100). The storage location is preferably a location that is easy to transport to each IPP operator 7.

Then, the IPP business operator 7 and the leasing company 5 conclude a reservation right contract for a plurality of years (S101). Based on this contract, the IPP operator 7 pays the leasing company 5 the retainer fee annually (S102). This retainer cost is set as cheap as the volume zone. The leasing company 5 stores the transformers in stock in a state containing insulating oil, and regularly performs maintenance. Then, the transformer of the IPP company 7 that has concluded the sales reservation right contract is remotely monitored by the system operated by the leasing company 5 in order to grasp the state. Transformer accident rates are very low. Therefore, it is difficult to identify the IPP operator 7 that has many accidents stochastically. Therefore, the sign of failure is diagnosed by remote monitoring of the transformer.

Then, in the event of a transformer accident, the IPP company 7 concludes a short-term delivery sales contract with the leasing company 5 based on this reservation right contract. Based on this quick delivery contract, the leasing company 5 delivers the inventory to the IPP company 7 (S103), and the IPP company 7 pays the equipment price (S104).

FIG. 2 is a diagram showing an example of exchange of information and goods at the time of an accident according to the present embodiment.
First, the IPP company 7 notifies the leasing company 5 of the replacement request (S111).
The leasing company 5 informs the management company of the storage 51 of the target product (S112), and instructs the transportation company 52 to transport the transformer (S113). As a result, the leasing company 5 calculates the delivery deadline information using a computer based on the situation of the carrier 52 and the storage 51. The leasing company 5 notifies the IPP company 7 of the delivery deadline (S114), and further informs the arrival date and time (S115). Information communication such as e-mail is assumed for the communication between the leasing company 5 and the management company of the storage 51.

The transporter 52 informs the manager of the storage 51 to pick up the transformer (S116). After that, the transporter 52 transports the transformer from the storage 51 (S117). Since the leasing company 5 has previously formulated the optimum transportation method for each transformer according to the route, weather, and model, it is not necessary for the transportation company 52 to consider the storage location and the transportation route. The transporter 52 transports and delivers the transformer to the power generation facility of the IPP operator 7 according to a predetermined transport method (S118).

The leasing company 5 contacts the manufacturing company 6 to replenish the transformer (S119). The manufacturing company 6 replenishes the storage 51 with a transformer (S120) and notifies the leasing company 5 that the transformer has been delivered (S121).

The lineup of transformers stored in the storage 51 has already been decided at the stage of concluding a contract with the IPP business operator 7, which is a customer. The number of transformers in stock is determined from the accident rate and failure data of each transformer. In Japan, the frequency of transformer accidents is about once a year. This system manages the number and timing of transformer accidents as asset management for each IPP operator 7. Then, as a method of selecting a transformer from inventory, it is conceivable that the customer selects the transformer, or preferentially selects the transformer having the same voltage and has been maintained most recently.

Although it is important that the transformer stored in the storage 51 can be delivered, if it is unavoidable such as a shortage, it will be treated as an exemption from liability. If the transformer cannot be delivered to the site of the IPP company 7 in a short delivery time due to a shortage or the like, the penalty may be a condition such as refund or double refund of the retainer fee paid up to that point. This can increase the likelihood that the IPP operator 7 will accept this agreement.

Since the transformer specifications differ for each IPP company 7, the transformer inventory is roughly divided into 2 to 3 classes and stored. It is advisable to stock multiple transformers in each class. As a result, even if transformer accidents occur continuously, it is possible to prevent shortages.
For the installation of the transformer on site, the basic part (adjuster) of the transformer and the transformer body are brought to the site and assembled on the spot.

FIG. 3 is a block diagram of the server 1 of the portal site.
The server 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage unit 16, and a communication unit 17. This server 1 operates as a processing unit of the portal site of the reservation right contract system S shown in FIG.

The CPU 11 executes a program stored in the ROM 12, the RAM 13, or the storage unit 16 and processes the data stored in the ROM 12, the RAM 13, or the storage unit 16.
The ROM 12 is composed of a non-volatile memory, and stores, for example, a BIOS (Basic Input / Output System). The RAM 13 is composed of a volatile memory and is used as a variable or the like temporarily stored by the program. The storage unit 16 is composed of a large-capacity storage device such as a hard disk or SSD (Solid State Drive), and internally includes a reservation right contract program 161, a transformer information 162, spare parts information 163, a transportation route 164, and management information. 165, the transportation period adjustment table 166 is stored.

The reservation right contract program 161 is executed by the CPU 11 to embody the processing of the portal site of the reservation right contract system S shown in FIG.
The transformer information 162 is information on the transformer included in the power generation equipment operated by each IPP operator 7. Spare parts information 163 is information on spare parts applicable to the power generation equipment operated by each IPP operator 7. The transportation route 164 is information on the transportation route from the storage 51 to the power generation facility operated by the IPP operator 7.

The management information 165 is information that links the transformer information 162, the spare parts information 163, and the transportation route 164 for each IPP operator 7. The transportation period adjustment table 166 is a table in which transportation periods according to each transportation route and weather conditions are stored.

The server 1 further includes an input unit 14 and a display unit 15.
The input unit 14 is, for example, a keyboard or a mouse, and is used to input various information to the server 1.
The display unit 15 is, for example, a liquid crystal display, and the server 1 is used to display a processing result or the like.
The communication unit 17 is, for example, a NIC (Network Interface Card), and the server 1 is used for transmitting and receiving data to and from an external terminal and an IoT (Internet Of Things) sensor.

FIG. 4 is a system configuration diagram showing a portal site.
The portal site includes a reservation right contract system S, terminals 21 to 23 connected to the reservation right contract system S, and a sensor 31 for detecting the state of the transformer 3. The sensor 31 functions as a measuring unit that measures the state of each transformer 3 included in the site operated by each IPP operator 7.
The terminal 21 is managed by the IPP operator 7 shown in FIGS. 1 and 2. The terminal 22 is managed by the leasing company 5. The terminal 23 is managed by the manufacturing company 6. The management company and the transportation company 52 of the storage 51 do not directly access the portal site, but store and transport the storage and transportation by contact from the leasing company 5.

The reservation right contract system S includes the server 1 of FIG. The reservation right contract system S acquires the state of the transformer 3 by remote monitoring using the sensor 31, and thus detects a sign of failure of the transformer 3. In the transformer 3, a sporadic discharge phenomenon called partial discharge occurs as a pre-stage of dielectric breakdown, which is a failure of equipment. The server 1 of the reservation right contract system S can catch a sign of failure of the transformer 3 by observing and monitoring the partial discharge. The reservation right contract system S actually remotely monitors the transformer 3 managed by a plurality of IPP operators 7, but in FIG. 4, only a single IPP operator 7 is shown for simplification. doing. However, the method of observing and monitoring the partial discharge is an example of the method of catching the failure sign of the transformer. Another way to detect signs of transformer failure is to analyze the oil gas inside the transformer.

The reservation right contract system S is further communicably connected to the weather information site 4 to acquire forecast information of future weather. As a result, the transportation period of the spare parts of the transformer 3 can be adjusted.

FIG. 5 is a flowchart showing the entire processing of the portal site. When the IPP operator 7 accesses the portal site by a terminal or the like, the process of FIG. 5 starts.
The CPU 11 of the server 1 displays a screen asking whether or not the reservation right has been issued on the terminal (S10), and waits for the input of the IPP operator 7 who is the user. If the reservation right has not been issued (No), the CPU 11 of the server 1 performs the reservation right issuance process of the target spare part (S11), and proceeds to the process of step S12. The process of step S11 will be described in detail with reference to FIG. 6 described later. By issuing the reservation right, a reservation right contract is concluded between the IPP company 7 and the leasing company 5.
Here, the CPU 11 functions as a issuing unit that issues a reservation right for spare parts for replacing the device included in the site operated by the IPP business operator 7 to the IPP business operator 7.
If the reservation right has already been issued (Yes), the CPU 11 of the server 1 proceeds to the process of step S12.

In step S12, the CPU 11 determines whether or not the replacement request from the IPP operator 7 has been acquired. If the CPU 11 has not acquired the replacement request from the IPP operator 7 (No), the CPU 11 ends the process of FIG. If the CPU 11 obtains the replacement request from the IPP operator 7 (Yes), the CPU 11 proceeds to step S13.

The CPU 11 collates the management information 165 (S14), identifies the transformer information 162, the spare parts information 163, and the transportation route 164 to be replaced, and determines whether or not the spare parts corresponding to the storage 51 are in stock. Is confirmed (S14).

The CPU 11 determines whether or not the storage 51 has an inventory of spare parts as the target device (S15). Specifically, the CPU 11 displays the inventory information management screen of the storage 51 in response to the request of the terminal 22 of the leasing company 5. The leasing company 5 inputs the inventory information of the storage 51 in advance via the terminal 22. Inventory information of spare parts is stored in the storage unit 16 of the server 1.
If the target device is in stock in the storage 51 (Yes), the CPU 11 proceeds to the process of step S18. If the target device is out of stock in the storage 51 (No), the CPU 11 proceeds to the process of step S16.
Here, when the CPU 11 acquires the device replacement request from the IPP operator 7 having the reservation right, the CPU 11 functions as a confirmation unit for confirming the inventory of spare parts.

In step S16, the CPU 11 inquires the manufacturing company 6 about the delivery date. The CPU 11 obtains a delivery date from the manufacturing company 6 for replenishing the transformer 3 in the storage 51 (S17). After that, the manufacturing company 6 replenishes the storage 51 after the production of the transformer 3 is completed.
When the spare parts are not in stock, the CPU 11 functions as an acquisition unit for acquiring a replenishment delivery date of the new spare parts from the manufacturing company 6.

In step S18, the CPU 11 acquires the transportation route 164 from the storage 51 to the site (power generation facility) of the IPP operator 7. The CPU 11 functions as a transportation period calculation unit that calculates a transportation period until the spare parts in stock are transported to the site of the IPP operator 7.
When the CPU 11 calculates the delivery date (S19) and displays the necessary information on the terminal 21 of the IPP operator 7 (S20), the process of FIG. 5 ends. Here, the necessary information includes the delivery date of spare parts, the current management information, the issuance information and status of the reservation right, and the like, and is displayed on, for example, My Page 8 shown in FIG. 7 described later. The CPU 11 may display necessary information on the terminal 22 or the terminal 23 depending on the situation.
The CPU 11 functions as a delivery date calculation unit that calculates the period until the spare parts are delivered to the site of the IPP operator 7.

By the series of processes described above, the information of the IPP business operator 7 which is a customer and the leasing company 5 which is an administrator can be centrally managed, and the status of the reservation right and the delivery date can be visualized.

FIG. 6 is a flowchart showing the details of the reservation right issuance process.
In step S30, the CPU 11 displays the transformer information acquisition screen on the terminal 21. The IPP operator 7 makes a predetermined input on the input screen. The CPU 11 acquires the input information as transformer information 162.

In step S31, the CPU 11 displays the spare part information acquisition screen on the terminal 21. The IPP operator 7 makes a predetermined input on the spare parts information acquisition screen. The CPU 11 acquires the input information as spare part information 163.

In step S32, the CPU 11 displays the site information acquisition screen on the terminal 21. Here, the site refers to a power generation facility operated by the IPP operator 7. The IPP operator 7 makes a predetermined input on this site information acquisition screen. Based on the input information, the CPU 11 searches for a transportation route from the storage 51 to the site (S33), and identifies the transportation route 164.
The order of acquisition of transformer information 162, acquisition of spare parts information 163, and acquisition of site information is not limited to the above, and may be any order.

In step S34, the CPU 11 associates the transformer information 162, the spare part information 163, and the transportation route 164 to generate the management information 165. After that, the CPU 11 issues a reservation right for the target spare part (S35), and ends the process of FIG.

FIG. 7 is a screen example showing My Page 8 for the IPP business operator 7 of the portal site.
The My Page 8 is, for example, a screen displayed on the terminal 21 of the IPP operator 7. My page 8 includes a login information area 80, a contract information area 81, and a storage information area 83 in this order from the top.

The login information area 80 is located directly below the title bar of My Page 8 and is an area for displaying the name of the logged-in IPP operator 7.
The contract information area 81 is located directly below the login information area 80, and displays transformer information 81 to 813 and replacement request buttons 821 to 823.

In the transformer information 811, the information relating to the transformer A-1 is displayed surrounded by a solid rectangle, and it is indicated that the transformer A-1 is under contract. A replacement request button 821 is displayed directly below the transformer information 811. By clicking the replacement request button 821, the leasing company 5 is notified of the replacement request for the transformer A-1.

In the transformer information 812, the information related to the transformer B-1 is displayed surrounded by a broken line rectangle, indicating that the transformer B-1 is not under contract. Immediately below the transformer information 812, the replacement request button 822 is invalidly displayed, indicating that the replacement request cannot be issued.

In the transformer information 813, the information related to the transformer C-1 is displayed surrounded by a broken line rectangle, indicating that the transformer C-1 is not under contract. Immediately below the transformer information 813, the replacement request button 823 is invalidly displayed, indicating that the replacement request cannot be issued.

When a failure occurs in the transformer 3, the IPP operator 7 has room to decide whether to repair or replace the transformer 3. When the IPP company 7 replaces the failed transformer 3, the leasing company 5 or the like is contacted by the replacement request buttons 821 to 823 displayed on My Page 8 of the IPP company 7 on the portal site.

Spare parts information 831 to 833 is displayed in the storage information area 83.
Spare part information 831 is information on the spare device 1, and its voltage, capacity, and dimensions are displayed. By showing the detailed specifications in this way, it is shown that the spare device 1 is in stock.
Spare part information 832 is information on the spare device 2 and indicates that it is scheduled to be shipped.
Spare part information 833 is information on the spare device 3, and it is displayed that the product has been shipped.

The storage information area 83 of My Page 8 is a place open to each IPP business operator 7, and the status of exercising the reservation right can be grasped. By displaying on My Page 8 in this way, the reservation right contract system S declares the exercise of the contract right fairly and constantly to each IPP business operator 7.
The storage information area 83 does not disclose "who" exercised the reservation right, and is displayed so that it can be seen that someone has exercised the reservation right.
The CPU 11 and the terminal 21 function as a notification unit that notifies each business operator of the status of spare parts in stock.

8A and 8B are flowcharts showing a delivery date calculation process and a penalty calculation process due to out of stock. When the IPP operator 7 accesses the portal site by a terminal or the like, the processes of FIGS. 8A and 8B start.
The CPU 11 of the server 1 displays a screen asking whether or not the reservation right has been issued on the terminal (S40), and waits for the input of the IPP operator 7 who is the user. If the reservation right has not been issued (No), the CPU 11 of the server 1 performs a process of issuing the reservation right of the target spare part (S41). By issuing the reservation right, a reservation right contract is concluded between the IPP company 7 and the leasing company 5.
If the reservation right has already been issued (Yes), the CPU 11 of the server 1 proceeds to the process of step S42.

In step S42, the CPU 11 determines whether or not the replacement request from the IPP operator 7 has been acquired. If the replacement request from the IPP operator 7 has not been obtained (No), the CPU 11 ends the processes of FIGS. 8A and 8B. If the CPU 11 obtains the replacement request from the IPP operator 7 (Yes), the CPU 11 proceeds to step S43.

The CPU 11 collates the management information 165 (S43), identifies the transformer information 162 to be replaced, the spare parts information 163, and the transportation route 164, and determines whether or not the spare parts corresponding to the storage 51 are in stock. Is confirmed (S44).

The CPU 11 determines whether or not the storage 51 has an inventory of spare parts as the target device (S45). If the target device is in stock in the storage 51 (Yes), the CPU 11 proceeds to the process of step S51. If the target device is out of stock in the storage 51 (No), the CPU 11 proceeds to the process of step S46.

In step S46, the CPU 11 inquires the manufacturing company 6 about the delivery date. The CPU 11 obtains a delivery date from the manufacturing company 6 for replenishing the transformer 3 in the storage 51 (S47). When the CPU 11 calculates the penalty (S48), it returns the delivery date and the penalty to the leasing company 5 (S49). The calculation process of the penalty in step S47 will be described in detail with reference to FIG. 10 described later. The CPU 11 functions as a penalty calculation unit for calculating a penalty when spare parts are not in stock.
After the process of step S46, the manufacturing company 6 replenishes the storage 51 after the production of the transformer 3 is completed.

Next, the CPU 11 determines whether or not the IPP operator 7 continuously requests replacement (S50). If the IPP operator 7 does not continuously request replacement (No), the CPU 11 ends the process of FIG. 8B. If the IPP operator 7 continuously requests replacement (Yes), the CPU 11 proceeds to the process of step S51 in FIG. 8B.

In step S51, the CPU 11 acquires the transportation route 164 from the storage 51 to the site (power generation facility) of the IPP operator 7. The CPU 11 functions as a transportation period calculation unit that calculates a transportation period until the spare parts in stock are transported to the site of the business operator.
The CPU 11 acquires weather information from the weather information site 4 (S52), calculates the normal delivery date (S53), and adjusts the delivery date based on the failure information with reference to the transportation period adjustment table 166 (S54).

FIG. 9 is a diagram showing an example of the transportation period adjustment table 166.
The transportation period adjustment table 166 is a table showing the correspondence between each route and the transportation period according to the weather information.
The transportation period from the warehouse to Port X is usually 7 days, but it takes 14 days during precipitation or snowfall. The transportation period from Port X to Power Plant Y is usually 4 days, but it takes 8 days when it rains and 16 days when it snows. The transportation period from the port X to the power plant Z is usually 8 days, but it takes 16 days when it rains and it becomes impossible to transport when it snows. The CPU 11 applies each transportation route to the route of the transportation period adjustment table 166, and calculates the transportation period calculated by the combination of each route and the weather information. As a result, the CPU 11 can adjust the delivery date based on the failure information.

The explanation will be continued by returning to FIG. 8B. When the CPU 11 displays the necessary information on the terminal 21 of the IPP operator 7 (S55), the process of FIG. 8B ends. Here, the necessary information includes the number of days (delivery date) until the spare parts are delivered to the site of the IPP company 7, the current management information, the issuance information and status of the reservation right, and the like. For example, My is shown in FIG. It is displayed on page 8.

FIG. 10 is a flowchart showing an example showing details of the penalty calculation process. The processing for calculating the penalty corresponds to the processing in step S47 of FIG. 8A.
The CPU 11 determines whether or not the number of delivery days (delivery date) until the spare parts are delivered to the site of the IPP operator 7 is the number of days that can be exempted from liability (S60). If the delivery days are the number of days that can be exempted from liability (Yes), the CPU 11 ends the process of FIG.
If the number of delivery days is not the number of days that can be exempted from liability (No), the CPU 11 performs a penalty level determination process (S61), and multiple branches are performed according to the penalty level (S62). The penalty level determination process is, for example, a process of subtracting the number of days that can be exempted from the delivery days and determining the penalty level from the obtained days.

In step S62, if the penalty level is less than 1, the CPU 11 determines the level 1 penalty (S63) and ends the process of FIG. Similarly, if the penalty level is less than n, the CPU 11 determines the penalty for level n (S64) and ends the process of FIG. 10. If the penalty level is n or more, the CPU 11 determines the maximum level penalty (S65) and ends the process of FIG.
The method of determining the penalty level is not limited to the number of days until the spare parts are delivered to the site of the IPP operator 7. When the inventory of spare parts, which are the target devices, is out of stock in the storage 51, the penalty level may be determined by the period (replenishment days) until the inventory is replenished in the storage 51.

FIG. 11 is a flowchart showing storage inventory optimization by predictive diagnosis utilizing transformer monitoring. The CPU 11 constantly performs this process at a predetermined cycle.
The CPU 11 acquires information on the state value of the transformer 3 from the sensor 31 (S70), and analyzes the state value as data (S71).

The CPU 11 determines whether or not the acquired state value exceeds the reference value (S72). If the acquired state value does not exceed the reference value (No), the CPU 11 proceeds to the process of step S78. If the acquired state value exceeds the reference value (Yes), the CPU 11 performs the device failure determination process (S73).

In step S74, the CPU 11 determines whether or not the cause of the acquired state value exceeding the reference value is an accident. If it is not an accident (No), the CPU 11 proceeds to the process of step S78, and if it is an accident (Yes), it collates with the management information 165 (S75) and confirms the inventory of the storage 51 (S76).

In step S77, the CPU 11 determines whether or not the target device is in stock in the storage 51. If the target device is in stock (Yes), the CPU 11 ends the process of FIG. If the target device is out of stock (No), the CPU 11 proceeds to step S82 and inquires the manufacturing company 6 about the delivery date. When the CPU 11 obtains the delivery date for replenishing the transformer 3 in the storage 51 from the manufacturing company 6 (S83), the CPU 11 ends the process of FIG.

In step S78, the CPU 11 performs normal data comparison processing. The CPU 11 determines whether or not the acquired state value is abnormal (S79). This is because the state value may deviate from the range of normal data even if it is within the range of the reference value. If the acquired state value is normal (No), the CPU 11 ends the process of FIG. 11, and if the acquired state value is abnormal (Yes), the CPU 11 calculates the remaining life (S80). That is, the CPU 11 functions as a remaining life calculation unit that calculates the remaining life of the device according to the state measured by the sensor 31 that is the measuring unit.
The CPU 11 monitors not only the life value obtained by monitoring one transformer, but also the transformer 3 related to the issuance of the reservation right for at least each IPP trader, and calculates the remaining life.

In step S81, the CPU 11 determines whether or not the remaining life is shorter than the standard replenishment days. If the remaining life is equal to or longer than the standard replenishment days (No), the CPU 11 calculates the replenishment time to the storage 51 (S84), and ends the process of FIG. If the remaining life is shorter than the standard replenishment days (Yes), the CPU 11 asks the manufacturing company 6 for the delivery date of this transformer (S82). The CPU 11 obtains a delivery date from the manufacturing company 6 for replenishing the transformer 3 to the storage 51 (S83), and ends the process of FIG. After step S82, the manufacturing company 6 replenishes the storage 51 after the production of the transformer 3 is completed.

FIG. 12 is an example of a graph showing a method of calculating the remaining life. The vertical axis of the graph is the state value acquired from the sensor 31. The horizontal axis of the graph is the elapsed time.
On the reference date, the state value exceeds the reference value and deviates from the range of normal data. After that, the determination result in step S72 in FIG. 11 becomes Yes, and the device failure determination process in step S73 is performed. Since the accident determination result in step S74 is No, the normal data comparison process in step S78 is performed. Further, since it is determined in step S79 that the state value is abnormal, the remaining life calculation process is performed.

In the remaining life calculation process, as the first method, the CPU 11 finds an abnormality different from the normal operating state, and predicts when the device will be damaged from the data transfer. Furthermore, as a second method, the CPU 11 calculates the load operation status based on the sensor output (oil temperature, winding temperature), the operating time per day, and the aging, and predicts how many years it should be replaced. To do.

In the second method, Arrhenius's law applies. Specifically, when the winding temperature is 95 ° C. and continuous operation is performed, the expected life is X years. The life is halved when the winding temperature is 6K higher than the winding temperature during the operation, and the life is doubled when the winding temperature is 6K lower than the winding temperature during the operation.
It is preferable that the CPU 11 implements both the first and second methods and selects the one having the shorter remaining life and calculated.

Twenty days after the reference date, the remaining life rate is calculated to be 60%. After 50 days from the reference date, the remaining life rate is calculated to be 90%. At this time, if the calculated remaining life becomes shorter than the standard replenishment days, a delivery date inquiry is made to the manufacturing company 6 (S82), and the manufacturing company 6 starts manufacturing the transformer. As a result, the spare parts of the transformer 3 can be delivered to the storage 51 by the time when the transformer actually breaks down.
When the state value exceeds the failure detection value, it is determined that the transformer 3 has failed. At this time, since the accident determination result in step S74 is Yes, a series of processes from steps S75 to S77 are executed.
