ある。In the power system operation method according to the present invention, the connection state of the current system and the target system is converted into a node indicating a range where facilities having zero impedance are connected and a branch indicating facilities connecting two nodes with impedance. Then, in the current system, an arbitrary bus node is connected by a plurality of line branches, and when the target system has one branch connecting the same node or the node is divided, the branch between the nodes becomes one. For the reclosing relays of the lines that make up the remaining one branch in the case where there is a "single-phase reclosing method", the "3-phase collective reclosing method" is automatically created.
If there is no "single-phase reclosing method" for the switching procedure, a "lock" procedure for the reclosing relay is automatically created.

する手順を作成する。According to the present invention, when two lines are currently operated on the system and one line is stopped on the target system, two branches are connected between the nodes on the current system. In the above, since there is only one branch connecting between the same nodes, the procedure for the reclosing relay of the lines constituting the remaining branches is created, and the two lines currently operating on the system are changed to the target system due to system change. Even in the case of the above-mentioned distribution operation state, two branches are connected between nodes in the current system, whereas on the target system, the nodes are divided and one branch connects the nodes. First, a procedure is created for the reclosing relay of the line that has become one branch.
