PROBLEM TO BE SOLVED: To provide a maintenance assistance system for power system installations capable of preventing electrification accidents that can occur during maintenance of power system installations or when energizing the power system installations.SOLUTION: A maintenance assistance system 10 for power system installations includes maintenance assistance means 3 for assisting maintenance of a power system installation 1, and a control unit 4 for controlling the power system installation 1 with control commands from the maintenance assistance means 3 which is connectable with the control unit 4 via a LAN 5. The maintenance assistance means 3 also has an interlock information generating unit which generates interlock information when a distance from an operator to the power system installation 1 is more than a predetermined threshold value. Furthermore, the control unit 4 has an interlock determination unit which allows the control unit 4 to start controlling the power system installation 1 and determines that the power system installation 1 can be energized, when the power system installation 1 is in a power cut-off state, according to the interlock information generated by the interlock information generating unit. |
