西气东输二线、三线SCADA系统时钟同步方法研究

摘要

针对目前西气东输二、三线SCADA系统时钟同步功能不完善的现状，本文通过对系统各个设备的时钟同步方法进行研究，通过编程方式实现VEIWSTAR上位机软件与AB 、BB PLC的时钟同步方法，提出整个系统时钟同步架构，为实现西二、三线站场SCADA系统时钟同步提出清晰的思路及可行的方法。%This paper researched the clock synchronization methods for the different equipments, according to the current status of the second and third west-to-east gas pipeline SCADA system .Realized the clock synchronization method for VEIWSTAR HMI software with AB PLC and BB PLC, presented the whole clock synchronization architecture for the system, presented the clear thinking and viable methods to realize clock synchronization for the second and third west-to-east gas pipeline SCADA system.
