DCS通信网络故障的分析及防范措施

Analysis on DCS Communication Network Fault and Its Prevention

随着分散控制系统(DCS)在大型火电厂的广泛应用,其通信网络的安全运行变得越来越重要。为此总结了DCS死机及网络通信故障的常见原因,对近年来在安徽电网火电厂中发生的两起DCS通信网络故障实例进行了深入细致地分析,提出了有效防止DCS通信故障的防范措施。

Along with the wide application of DCS,the safe operation of communication network is becoming more and more important. This paper summarizes the common causes for DCS breakdown and network communication troubles. A detailed analysis was made on the two failures of DCS communication network in recent years in a power plant in Anhui power network. And effective measures were put forward to prevent DCS communication failure.
