摘　　要：随着电力系统的发展,分布式电力监控系统对时钟同步精度的要求越来越高,已经提出了微秒级的要求。为满足此要求,对IEEE1588精确网络时钟同步协议进行了研究,对该协议实现高精度时钟同步的原理进行了阐述,并针对时钟同步过程中网络延迟不对等的问题,使用移动平均算法对IEEE1588的同步过程进行了改进,并予以验证。With the development of the power system,the distributed power monitoring and control system of clock synchronization precision demand is higher and higher,and have put forward the requirements of microsecond. To satisfy this requirement, IEEE 1588 precise network clock synchronization protocols were studied in this article,and exposited the principle of high precision clock synchronization. In view of the clock synchronization network latency is dis-symmetry in the process of problems,that using moving average algorithm was proposed to improve the synchronization process of IEEE1588,and finally it was verified.
