Abstract

The communication network of wide-area stable control in power system requires high precision of time synchronization. At present, substations are all configured with satellite receivers to realize time synchronization, and ground network has not been realized yet, which has a large potential safety hazard. In order to achieve high-precision clock synchronization on the network in power system, this paper proposes to build the main standby time synchronization system in the station with GPS and Beidou, and implement the time synchronization between stations by IEEE-1588 protocol, so that a three redundant time synchronization system is formed with GPS, Beidou and network. A high precision time synchronization scheme based on network is implemented to meet the high accuracy and reliability requirements of wide area measurement in power system.
