高加水位调节改造在华能大连电厂的应用

Application of High Water Level Regulation Reform in Huaneng Dalian Power Plant

高压加热器水位的控制关系到电厂运行的经济性和安全性,因此保持高加水位的稳定有着至关重要的意义。本文根据华能大连电厂高加水位改造的经验,提出了一种高加水位的控制方案,并对该方案的组成、原理、逻辑设计进行了详细的介绍。

The water level control of high-pressure heater is related to the economy and safety of power plant operation,so it is very important to maintain the stability of high-pressure heater water level.Based on the experience of high water level renovation in Huaneng Dalian Power Plant,this paper puts forward a control scheme of high water level,and introduces the composition,principle and logical design of the scheme in detail.
