Abstract
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.关键词
