ことを目的としている。The information is taken in by the configuration shown in FIG. 11, for example, the distribution system operation device 1a of the A sales office is connected only to the distribution system under the jurisdiction of the A sales office, Similarly, the distribution system operating device 1b of the B sales office is connected only to the distribution system under the jurisdiction of the B sales office. As can be seen from the above description, the area beyond the normally open switch S4 is not displayed although it is connected to the distribution line under the control of another business office. This is because the storage device 19 of the A sales office does not have the facility data and the distribution system diagram display data of the distribution lines under the jurisdiction of other sales offices beyond the normally open switch S4. Further, even if it is owned, it cannot be displayed because the substation operating status information under the jurisdiction of other business offices and the switch status information of the interconnection destination distribution line are not captured. Therefore, in the past, for example, an accident occurred in the section K2 and the sound power failure section K3
When trying to exchange power from a distribution line under the jurisdiction of another sales office,
After inquiring about the charging / discharging state of the connection destination section of the normally open switch S4 to other business offices by radio or telephone, the closing control of S4 was manually performed. The conventional distribution line automatic control system does not have a distribution line facility or a database for displaying distribution line diagrams in other jurisdictions, so it is not possible to grasp them and the distribution line near the sales office boundary cannot be grasped. It was not possible to automate the monitoring and control of electric wires. In addition, monitoring control may be performed due to incorrect information. In this case, the range of power supply hindrance is further expanded, which may have a great social impact. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power distribution system operation device capable of smoothly monitoring a power system even in a power distribution line with a branch office.

御を行なう。[Operation] According to claim 1, the facility data in the jurisdiction of the self-employed office, the distribution system display data and the facility data of the other sales office and the distribution system display data are provided. The substation operating state information and the distribution system display information in the jurisdiction of the self-employed offices are mutually transmitted via the transmission line 300.
Therefore, the data of both adjacent sales offices can be displayed at the mutual sales office. According to a second aspect of the present invention, the device status input means of the distribution system operation device captures the device status sent from the adjacent distribution system operation device through the network to determine the device status of the adjacent distribution line. The amount of electric power is stored in the adjacent distribution system information storage unit that stores the amount of electric power. The distribution system information monitoring means inputs the device status and the amount of power in the distribution system operating device under the jurisdiction of the distribution system through the remote monitoring and control device master station, and stores the device status and the amount of power of the distribution line in question. Stored in the information storage means. Regarding control, first search for the required control from the distribution system information storage means,
After that, the adjacent distribution system information storage means is searched. If it is detected by the distribution system information storage means, it becomes the same as the conventional control operation in the distribution system operation device. However, if it is not detected by the distribution system information storage means but is detected by the adjacent distribution system storage means, the operation request output means requests the adjacent distribution system operation device to operate via the network coupling device. On the contrary, when the operation request input means is notified of the operation request from the adjacent distribution system operation device via the network coupling device, the control output means controls the corresponding device of the distribution system.

る。7 and 8 will be described with reference to these notification types and notification contents. In the figure, the left distribution line is FA and the right distribution line is FB. In Fig. 7 (1), the interconnecting normally open switch is in the on state and the switch b2 is in the off state, and the distribution line FB is connected to the switch b1.
Electric power is supplied from the distribution line FA to the section delimited by b2, and in the distribution system operation device FA in which the distribution line FA is the distribution line under jurisdiction, the information on the adjacent distribution line FB is off. In Fig. 7 (2), the distribution line FB has lost power, and the interconnecting normally open switch and switch b1 are open without voltage. In this case, the distribution system operation device 1a sends a power failure notification to the distribution system operation device 1b having the distribution line FB as a jurisdiction distribution line, the distribution system operation device 1b turns off the information of the adjacent jurisdiction distribution line FA, and b1 is a non-voltage line. Make it open. After that, when the power failure section is restored as shown in Fig. 7 (3), a charging notification is sent and the adjacent distribution line F
The information of A is entered. In FIG. 7 (4), the connection normally open switch of the distribution line FA is controlled to be closed, and a notice of connection is sent to the distribution line FB, and the information of the connection normally open switch is input to the distribution line FB. In FIG. 7 (5), the switch b2 is controlled to be closed, but since it is not an interconnecting normally open switch, the closing notification is not issued. Also, FIG.
When the switch b1 is turned on as in (6), a loop occurs, so a loop occurrence notification is sent to the distribution line FA. Then, the distribution line FA which has received the notification enters the information of the adjacent distribution line FB.

能となるため、電力供給支障の範囲を最小限にとどめ、
より完全な配電自動化を推進することができる。FIG. 8 (1) is an example of the loop cancellation notification. When the switch a1 is turned off and the loop cancellation notification is sent to the distribution line FB,
The distribution line FB that received the notification turns off the information of the distribution line FA that is under jurisdiction. Further, FIG. 8 (2) shows the case where the distribution line FB has a power failure, and the processing is the same as that of FIG. 7 (2). Subsequent charge notification The processing of FIG. 8 (3) is also similar to that of FIG. 7 (3). At this point in time, the distribution line FA is out of power, so that the interconnecting normally open switch is closed and controlled in the distribution line FA, power is supplied from the distribution line FB, and a closing notice is sent to the distribution line FB. Also, FIG. 8 (5)
When the switch a1 is controlled to be closed as described above, a loop is generated, and therefore a loop occurrence notification is sent to the distribution line FB. According to the embodiment as described above, the information of the adjacent distribution line can be input online from another distribution system operating device, and thus accurate remote monitoring control can be performed even in the adjacent distribution line. , Minimize the range of power supply interruption,
More complete distribution automation can be promoted.
