ABSTRACT:
The intelligent substation realizes the digitization of
information in the whole substation and thus time synchronization system becomes
more and more important. This paper introduces time synchronization technology
of intelligent substation and puts forward the principles for designing
intelligent substation time synchronization system. According to some relay
protection malfunction examples caused by time synchronization system fault, analyze
the influence of time synchronization system fault to relay protection and correspondingly
put forward some improving measures.
