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 。
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.
