摘要

华能珞璜电厂二期 2× 36 0MW机组DCS采用法国CEGELEC公司设计制造的ALSPAP32 0系统

其中FSSS系统采用P32 0逻辑程控方式与硬接线逻辑方式共同实现

二者构成相互冗余结构

锅炉保护动作采用二选一动作形式。此外

还对所有重要保护输入信号进行奇偶校验

当校验有误时

锅炉主燃料跳闸保护将动作

Abstract

The DCS of 2×360 MW units in phase 2 of Luohuang Power Plant was using ALSPAP320 system designed and manufactured by CEGELEC Company

France. The FSSS system in the said DCS was jointly realized by using P320 programmed logic controllers and hard-wired logic mode

constructing a mutual redundant structure

enabling the boiler to trip according to an optional mode of the two channels. In addition

each important input signal should be checked for parity

if error appears in the parity check

the main fuel trip protection of the boiler will be promptly actuated.
