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.
