摘要
由于缺少细化的工程技术导则,目前厂级监控信息系统(SIS)在安全性设计方面存在隐患。根据《电力二次系统安全防护规定》的要求,从发电厂的实际情况出发,对监控信息系统的安全防护进行分析和探讨,并对监控信息系统的安全等级合理定位,在保障电力监控系统安全的前提下,对各系统间安全隔离方式进行灵活组合设计,并详述监控信息系统的安全防护设计方案及相关系统的改造。
Owing to lack detailed engineering and technical guidelines,the power plant Supervisor Information System（SIS）exists hidden dangers in the security design.According to the requests of ＂Rules of power secondary system security protection＂,combine with the actual situation of the power plant,analyzes and discusses the security protection of SIS,and reasonably orients a security level for SIS,under the premise of ensuring the security of power monitoring system,makes flexible combined design for secure isolation mode of each subsystem,and expatiates the design schemes of SIS safety protection and the improvement of the related systems.
