Taking Two from Three Protections Logic Optimizes Research of Drum Water Level

根据《防止电力生产重大事故的二十五项重点要求》中有关汽包水位保护的要求,结合东华热电2台机组汽包水位测量系统的实际运行情况和存在的问题,对其进行了三取二保护逻辑优化,简要的介绍了汽包水位三取二保护逻辑优化实现方法以及优化后的试验方法。

This paper optimizes taking two from three protections logic of drum water level for Donghua Thermoelectric Plant＇s two units,according to ＂25 key requirements to prevent major accidents of the electricity production＂,and Introduce optimization methods of taking two from three protections logic and test methods after optimization.
