Abstract:
PROBLEM TO BE SOLVED: To provide a high operability/maintainability power system protection control system that allows a plurality of external terminal devices to easily coordinate and to singly operate without interference.SOLUTION: A power system protection control device 1 includes a transmission interface capable of simultaneously connecting to a plurality of external terminal devices via a transmission line 2, and a control section for controlling a circuit breaker on the basis of the status of a power system. When a first one of a plurality of external terminal devices 3A-3C is in a connection state and a screen selection is made on the first external terminal device to display connection states of the others of the plurality of external terminal devices 3A-3C, the control section periodically returns connection status information about external terminal devices simultaneously connected to the power system protection control device 1 to the first external terminal device.
