摘　　要：以某核电厂3、4号机组DCS数字化网络为研究对象,介绍了基于I/A的DCS网络结构以及网络广播风暴的成因,重点分析了几种广播风暴的预防措施,包括生成树协议、VLAN、LDP阻断机制等。为避免任意一台机组的网络缺陷影响到另一台机组,某核电厂对两台机组的网络结构进行了优化,此优化方式对其他的双机组有一定的借鉴意义。Based on the DCS digital network of unit 3 and unit 4 of A nuclear power plant,the structure of DCS network based on I/A and the cause of network broadcast storm are introduced.The prevention measures of broadcast storm are analyzed,including spanning tree protocol,VLAN,LDP blocking mechanism,etc.In order to avoid the network defect of one unit affecting another unit,the network structure of two units in a nuclear power plant was optimized,which can be used for reference for other two units.
