Failure point locating system |
摘要 |
An accident point locating system locates an accident point on a power transmission line. A digital protective control system has a plurality of digital protective controllers that receive state data representing a state of an electric power system and convert the same into corresponding digital state data. An absolute time acquiring means acquires an absolute time when the state data is sampled. A state data processing decides whether any malfunction occurred in the power transmission system on the basis of the digital state and executes a protective operation when it is decided that an accident occurred in the power transmission system. A recording device adds an absolute sampling time to the digital state data and records the digital state data with the absolute time. A digital data sending device provides the digital state data with the absolute time on a communication network. A display operating system connected to the communication network executes displaying operations to monitor the operation and condition of the digital protective controllers. The display operating system has a distance calculating device for calculating a distance between a control station and an accident point by using the plurality of digital state data with the absolute time received from the digital protective controllers and a display for displaying the output of the distance calculating device. <IMAGE> |
