Research on Accuracy and Stability of Smart Substation Clock Synchronization
摘要
Abstract
Aiming at the existence of smart substation clock synchronization problem such as clock switching,time jump,long-term stability,these is developed appropriate research work. Design of the GPS and Beidou source switc-hing strategy,it put forward to punctual time clock source switching,tracking satellite logic thoughts,to ensure the continuity and stability of the system time;The scheme was optimized the pair of abnormal fault tree and the pair de-fect in protection mis-operation fault tree structure,the probability of the whole system for synchronous operation re-duces two orders of magnitude,it obviously improves the reliability and accuracy. The results show that the scheme is feasible,and effectively improves the stability and reliability of synchronous clock system.关键词
