A monitoring station for monitoring each of the operating stations is provided with a detection device for detecting, and a communication device capable of transmitting and receiving state data regarding the state of the operating station, detection data of the detection device, and drive data for the power distribution equipment. includes a communication device capable of transmitting and receiving each of the data, a calculation device that calculates drive data for each power distribution device based on the detection data and status data, and a storage device that stores the drive data calculated by the calculation device. a determination device that determines the section where the accident occurred according to the detected data; and an output device that reads drive data of the power distribution equipment in the section where the accident occurred from the storage device based on the determination by the determination device and outputs it to the communication device. An operating status monitoring system for a power distribution line, characterized in that: a communication device of each of the operating stations and a communication device of the monitoring station are connected by a communication line. 2. The control device of the operating station transmits the detection data and status data via a communication device at predetermined time intervals, and the storage device of the monitoring station stores power distribution equipment calculated based on each data received from the operating station. The output device of the monitoring station includes two storage devices for alternately storing driving data for the accident, and according to the data stored in either storage device that is not in operation, the output device of the monitoring station outputs the driving data corresponding to the section where the accident occurred. The operating status monitoring system for a power distribution line according to claim 1, wherein the system outputs: 3. When the determination device of the monitoring station detects the occurrence of an accident based on the detection data, the monitoring station determines the driving data corresponding to the next predicted accident occurrence section based on the driving data sent to each operating station. 3. The operating status monitoring system for a power distribution line according to claim 2, further comprising another arithmetic device for storing the information in the other storage device which was previously in operation and is currently inactive.
