Study on Substation Synchronization System Based on Master Clock Intelligent Decision

With the continuous improvement of automation level,the stability,reliability and accuracy of time synchronization system has become one of the key element in the safe and stable operation of power system.How to guarantee reliable operation of substation and the entire network time synchronization system becomes one of the key technology of power system research.In this paper,on the basis of existing research,according to the expansion upgrade of the master clock function,it proposes a master clock intelligent decision making of substation time synchronization system based on multi-source data to ensure the reliability of substation time synchronization system from the time source.
