第四十六讲:功能安全型控制系统在1000MW机组ETS系统的应用

摘要

本文介绍了功能安全型控制系统在1000MW汽轮机危急遮断系统(ETS)中的实践应用,并针对汽轮机ETS项目进行危险与可操作性(HAZOP)分析和安全完整性等级(SIL)评估,同时首次将功能安全概念运用到发电厂汽轮机控制系统.%Functional safety control system in 1000 mw steam turbine emergency trip system (ETS) practice application, and in view of the steam turbine ETS project hazard and operability (HAZOP) analysis and assessment of safety integrity level (SIL), at the same time for the ifrst time to apply functional safety power plant steam turbine control system.
