The building up of Beidou navigation satellite system developed by China offers a new option of the time service for synchronization phasor measurement. The feasibility of applying Beidou navigation satellite system to wide area synchronous phasor measurement for domestic power system is analyzed in respects of covered area of satellite signal, permissible amount of users, synchronous performance of time service pulse, etc. By means of comparative test of the synchronous phasor measurement using the time service from Beidou navigation satellite system and global positioning system (GPS) respectively, the availability of time service from Beidou navigation satellite system is verified. On this basis the distributed phasor measurement unit (PMU) using the mutually backup time service by both Beidou navigation satellite system and GPS is developed, and it is also the first time of applying the time service of Beidou navigation satellite system to power system.
