摘　　要：DCS系统是电厂重要的控制系统,而网络更是整个DCS系统的核心。网络故障产生的危害较大,可能造成设备失去监控、连锁失效、机组跳闸等严重后果。针对DCS系统发生环路网络风暴,出现大量控制器通信故障的问题,详细分析了分布式控制系统冗余网络广播环路产生的原因,提出分布式控制系统网络日常维护应注意的事项,对分布式控制系统环路网络风暴问题的处理提供了参考和借鉴。The DCS is an important control system of power plants, and the network is the core of DCS. The network failure could generate great harm, and it may cause serious consequences such as losing monitoring of equipment, chain failure, unit trip and so on. Focusing on the communication failure problems of controllers caused by turmoil loop network storm in DCS, this paper analyzes the reasons of the redundancy network broadcasting loop of the DCS, and proposes the daily maintenance of the DCS network, which provide a reference for dealing with loop network storm problems in DCS.
