摘　　要：某电厂按照"安全分区、网络专用、横向隔离、纵向认证"的原则,对二次系统采用链式防护结构,在相关部位布置了防护设备。介绍了某电厂二次系统安全防护方案的设计与实现,并详述了该电厂二次系统安全防护设备的配置及对相关系统的改造。According to the secondary system security protection principle ＂security location, network specialization, transverse isolation, longitudinal certification＂, a power plant installs its protection devices on related systems. This paper describes the design and implementation of the scheme which uses chain-structure. Also, configuration scheme of the secondary system security protection and the reformation of the related secondary system are introduced detailedly.
