日本三菱350MW火电机组DEH系统“负荷限制”回路的动作机理及改进

The Action Theory and The Problems in The “loadlimit” loop of Mitsubishi 350MW Unit DEH System

分析了日本三菱350MW火电机组DEH系统“负荷限制”回路的动作机理,指出其中存在的“半死锁”问题,提出了对负荷限制控制策略进行修改的初步解决方案。

The action theory of the ＂load limit＂ loop of Mitsubish 350 MW unit DEH system is analysed,its＂half dead lock＂ problem is pointed out, and the measure to modify the control scheme of load limit is put foreward.
