摘　　要：电力系统当前的对时方式有脉冲对时、编码对时以及网络对时3种。主要介绍了大连石化公司目前的同步对时系统网络,利用IRIG-B编码对时、简单网络时间协议(Simple Network Time Protocal,SNTP)网络对时2种方法,解决厂内保测装置时间不同步的问题。以二空压、主控变电所现有保测装置情况为例,选择一种简单、经济、安全的方法,实现站内保测装置时间同步,以此分析全厂类似问题,实现全厂电力系统保测装置时钟同步。At present,there are three synchronization methods in power system:pulse synchronization,coding synchronization and network synchronization.This paper mainly introduces the current synchronous time synchronization system network of Dalian Petrochemical Company,and uses IRIG-B(RS-485)coding time synchronization and Simple Network Time Protocal(SNTP)network time synchronization to solve the problem of time synchronization of in-plant monitoring devices.Taking the existing protection devices in the second air compressor and main control substation as an example,a simple,economical and safe method is selected to realize the time synchronization of the protection devices in the station,so as to analyze similar problems in the whole plant and realize the clock synchronization of the protection devices in the power system of the whole plant.
