Further, in the above embodiment, the interchange of the load of the electric power between the plurality of business offices has been described as an example, but it is clear that it can be applied to the operation of accommodating the electric power from the adjacent business office to the power failure section at the time of the distribution line accident. .

FIG. 3 is a block diagram of another embodiment. In FIG. 3, the same parts as in FIG. In this embodiment, in the flexible calculation in the event of an accident, the distribution line information in the other sales office jurisdiction which is the target of the spare feeder (the feeder that can be flexible to the healthy power failure section),
It is possible to exchange between distribution line automatic control devices installed in the adjacent business offices, and it is possible to smoothly carry out the accommodation by the accommodation calculation of the central processing unit of the own business office.
Furthermore, by establishing a flexible calculation processing method in the case where the distribution line under the jurisdiction of the self-employed office spans other sales offices, the flexible processing can be performed regardless of the switch type at the sales office boundary.

In FIG. 3, the boundary 17 between the A sales office and the B sales office is shown.
Is the position of the normally closed section switch S3. Therefore, the distribution line 12 drawn from the distribution line drawing breaker 11 of the distribution substation 10 under the jurisdiction of the A sales office is divided by the normally closed switchgear S1, S2, S3, and is a normally open interconnection switch. Electric power is supplied to the sections K1, K2 and K3 up to S4, S8 and S10. And each of these sections is a normally open interconnection switch S4, S8,
It is connected to the other distribution lines 22, 100, 101 by S10.

Further, normally closed section switches S1, S2, S3 and normally open interconnection switches S8, S10 are slave stations L1, L2, respectively.
L3, L16 and L5 are attached, and are connected to the central processing unit 15 by relaying the master station L6 through the transmission line 13. Further, the central processing unit 15 is configured to allow remote monitoring control. Further, the operation information of the distribution substation 10 is configured to be fetched into the central processing unit 15 from the substation monitoring slave station L8 through the transmission line 14 to the substation monitoring master station L7.

Next, the distribution line 22 drawn from the distribution line drawing breaker 21 of the distribution substation 20 under the jurisdiction of the B sales office is divided by the normally closed switchgear S5, S6, S7, and is normally open. Sections K4, K5, K6 to interconnection switches S4, S11, S9
Powering K7. Sections K5, K6, K7
Other distribution lines 201, 2 by normally open interconnection switches S9, S11
It is connected to 03 and 202.

Further, normally closed section switches S5, S6, S7 and normally open interconnection switches S4, S11, S9 are provided with slave stations L10,
L11, L12, L4, L17, L9 are attached, and the transmission line
The central processing unit 23 is connected to the central processing unit 23 by relaying the master station L13 by means of 18, and the central processing unit 23 enables remote monitoring control. Further, the operation information of the distribution substation 20 is configured to be fetched by the central processing unit 23 from the substation monitoring slave station L15 via the transmission line 19 to the substation monitoring master station L14. Further, the central processing units 15 and 23 of both business offices are connected via the transmission line 25 as described above.

For example, when an accident occurs in the section K1, the section K0, which is the power-supply side normal power failure section, is automatically restored by the time-sequential forwarding function of the slave station and the reclosing function of the distribution line drawing breaker 11. Sections K2 and K3 remain as a load-side healthy blackout section. Here, since the section K2 is under the jurisdiction of the A sales office, the accommodation processing is performed by the central processing unit 15 of the A sales office, and the section K3 is under the jurisdiction of the B sales office.
The central processing unit 23 of the sales office performs the accommodation processing.

At this time, if the accommodation processing is performed from the A sales office side, the distribution line is extended to the section K2, which is the section to be accommodated, through S8.
It will be accommodated from 101, but by charging the section K2, S3 is turned on by the timed progressive function of the slave station L3,
Power will be transmitted to the section K3 that is under the jurisdiction of the B business office, which causes a problem of arbitrarily transmitting power to the system under the jurisdiction of other business offices. Further, if the B office has been carrying out accommodation processing at the same time, the B office will create a procedure for accommodating the section K3, which is the section to be accommodated, from the distribution line 22 via S4. Then, there is a contradiction that it is already charged.

First, by establishing that the load side sales office will carry out the accommodation processing in the distribution line extending over the jurisdiction of other sales offices, the central processing unit of the B sales office will be processed first.
In accordance with 23, the section K3 is set as a section for accommodation and the accommodation processing is performed. After completion of this accommodation process, the accommodation result is calculated by the central processing unit.
23 to the central processing unit 15 via the transmission line 25,
The central processing unit 15 of the A sales office performs the accommodation process with the section K2 as the accommodation target section.

The central processing unit 15 of the A sales office receives the accommodation result from the B sales office (charging / outage information of the section under the jurisdiction of the B sales office that is connected to the system under the jurisdiction of the A sales office), and thus the section K
It can be seen that 3 is charged, and the distribution line information (current current, always allowable current, etc.) of distribution line 22 that is required when carrying out the accommodation calculation at the A sales office, and the substation of distribution substation 20 Since information (sending current, always-permitted current, etc.) can be received via the transmission line 25, the distribution lines 101 and 22 can be used as backup feeders.

As a result, in the accommodation calculation on the A sales office side, it is possible to accommodate the load from the B sales office, and it is possible to perform the accommodation processing in which the case where the accommodation becomes impossible is suppressed as much as possible. Further, it is possible to prevent the automatic introduction into the jurisdiction of other business offices which occurs when carrying out the accommodation processing from the A sales office and the contradiction which occurs when the accommodation processing is carried out at the A and B sales offices simultaneously.

FIG. 4 is a block diagram of still another embodiment. In this embodiment, the adjacent systems are connected by a wide area network, and the flexible calculation is performed including the distribution lines belonging to the adjacent systems.

When the accommodation calculation needs to be performed, the accommodation procedure creating means 102 is provided. to start. 102 is a flexible procedure creating means, which is a distribution line device status input means for the adjacent jurisdiction,
A flexible procedure is created based on the information obtained by the electric power amount input means of the adjacent jurisdiction distribution line, the managed distribution line system information monitoring means, and the facility information storage means. The operation execution means 103 executes the procedure created by the accommodation calculation creation means.

The operation execution means 103 issues an output request to the control output means 109 if the operation procedure is for the relevant distribution line, and issues an output request to the operation request means 110 if it is for the adjacent distribution line. The control means 109 outputs a signal to the remote monitoring control device master station 100d, and the remote monitoring control device slave station 100c controls the opening and closing of the switch. Further, the control request for the adjacent jurisdiction distribution line is sent to the network coupling device together with the power information of the jurisdiction distribution line, and transmitted to the distribution system operation device of the adjacent sales office via the network. The operation of the adjacent distribution line is performed by the distribution system operation device of the adjacent sales office.

Next, the operation will be described. The distribution system operation devices 100, 200 receive information (current state of each switch, bank voltage, bank current, distribution line current) regarding the relevant distribution line obtained from the remote monitoring control devices 100c, 100d from the distribution system information monitoring means 108. Take in through. Next, the fetched information is stored in the online information storage means 105, and the allowable currents of the banks and distribution lines stored in the equipment information storage means 104 are taken out, and then the surplus current, which is the difference between the currents, is calculated and online. It is stored in the information storage means 105.
Also, the section belonging to each distribution line and the standard section load of that section are taken out from the facility information storage means 104, the current section load current is proportionally divided by the standard section load, the current section load current is calculated, and the online information is stored. It is stored in the means 105.

When a power outage occurs due to an accident in the power distribution system, or when it is necessary to power out only in a specific area, the accommodation calculation is made when the accommodation calculation becomes necessary.

A device 7 and a man-machine interface device 8 for connecting each processing part and exchanging information with an operator.
Composed from.

It is assumed that the distribution system operating device is installed and operated in each of the A sales office and the B sales office. The monitoring control unit 4 takes in the status of the monitored control equipment of the distribution system under the jurisdiction of the self-employed office from the remote monitoring control apparatus 2, refers to the distribution system equipment data stored in the storage device 6, and responds to the change in the distribution system status according to the change. Control supervisory control equipment. The data management unit 5 distinguishes and stores the data of the power distribution system equipment under the jurisdiction of the self-employed office and other sales offices in the storage device 6 by inputting / outputting data to / from the man-machine interface device 8. Update this with the distribution system equipment data sent by other sales offices.

The storage device 6 stores the distribution system equipment data under the jurisdiction of the self-employed office and other offices. Information exchange device 7
Is connected to a distribution line monitoring and control device installed in another business office by a communication line and exchanges the stored distribution system equipment data. The man-machine interface device 8 is connected to the arithmetic processing device 3 and outputs the processing result of the arithmetic processing device 3 and inputs data according to a request from an operator.

FIG. 6 shows distribution system configuration data in the storage device 6. The power distribution system configuration data is divided into a power distribution system A file and a power distribution system B file for each supervisory control jurisdiction, and the equipment capacity, the equipment capacity, and the equipment connection information are stored in advance for each of the above equipment and equipment. Further, there is an area for storing measured values such as the open / closed state of equipment and devices, and voltage and current.

The outline of the operation is as follows. First, at the time of standard operation, the interconnection switch is open, the distribution line 12 is forwardly transmitted from the distribution substation 10, and the distribution line 22 is forwardly transmitted from the distribution substation 20. If an accident occurs between the division switch S1 and the division switch S2 in this state, the interconnection switch will be closed to recover from the distribution substation 20 in order to restore the power failure between the division switch S2 and the interconnection switch. Reverse power transmission will be performed in the section. In this case, the monitoring controller 4 in the distribution line operation device creates a switch operating procedure for this reverse power transmission by referring to the data of the distribution system A file and the distribution system B file. Then, according to the procedure, the remote monitoring control device controls the opening / closing of the corresponding switch.

On the other hand, when there is a change in the distribution system A and the distribution system B, the data management unit 5 needs to change the data of the distribution system A file and the distribution system B file in the storage device 6. For example, when the sorting switch S3 is temporarily removed for replacement, the S3 device data and S3 monitoring measurement data of the distribution system B file are deleted accordingly. The distribution system B is under the jurisdiction of the B sales office, and this data change is carried out by the operator of the B sales office to the distribution line operating device installed in the B sales office. This content is transmitted to the other distribution line operating device by the data management unit 5 and the information exchanging device 7 of the distribution line operating device.

Upon receipt of this, the data management unit 5 inputs this information via the information exchange device 7 and deletes the corresponding device data and the monitoring measurement data of the distribution system B file of the storage device 6. As a result, the distribution system B file of the distribution line operating device has the same contents as the other distribution system B files. These data changes are synchronized with each other by the data management unit 5, and exclusion is made so that the reference control is not updated by the monitoring control unit 4 during the data changes.

As described above, the distribution system equipment data commonly stored in the distribution line monitoring and control devices installed in the respective sales offices can be efficiently and always kept the same, and the sales offices are interconnected in a wide area. The power distribution system can be operated reliably.

It is customary for the operator of the sales office to change the distribution system equipment data of the distribution line monitoring and control device accompanying the construction of the distribution system. However, when business is busy, a situation arises in which the change cannot be made in a timely manner. As a result, not only the operation of the distribution line monitoring and control device at the self-employed office will be hindered, but also the operation of the distribution line monitoring and control device at other sales offices that commonly stores and refers to the distribution system equipment data will be hindered. It will be. Therefore, the data management unit 5 has a function of requesting the distribution line monitoring and control device of another sales office to change the distribution system equipment data stored in the storage device 6, and receiving and updating the contents of the execution. With this function, it is possible to change the distribution system equipment data that should be originally carried out at the other business office at another business office, and it is possible to improve the efficiency of the distribution system operation work.

In FIG. 5, the man-machine interface device 8 of the distribution line monitoring and control device allows the operator to see the operating status of the distribution system. Displaying the power distribution system on the CRT device and knowing the power distribution system of other sales offices is especially necessary for wide-area power distribution system operation. However, when the distribution system equipment data is being changed due to the construction of the distribution system B, if this state is not displayed on the CRT device of the distribution line monitoring control device that monitors and controls the distribution system A, the operator will make an error. It will be decided.

In the configuration of FIG. 5, the start and end of the change of the distribution system equipment data stored in the storage device 6 is transmitted to the distribution line monitoring and control device of another sales office, and the information is updated to the data. The data management unit 5 has a function of adding information inside. Man-machine interface device 8
Has a function of identifying the information being updated and outputting it in a form that can be judged by the operator. For example, the distribution line whose data is being changed is displayed on the CRT device in a predetermined color. With this function, the operator can appropriately know the change of the distribution system equipment data being executed at the other sales office, and the efficiency of the distribution system operation work can be realized.
