摘要

大型电站由于电网负荷的需求变化

机组在不同负荷下运行的主要辅机和系统也不尽相同。华能珞璜电厂4台360MW机组平均厂用电率在9.5%左右

在机组低负荷下通过改变给水和循环水系统的运行方式

平均厂用电率比改造前下降一个多百分点

降低了发电成本。

Abstract

Along with demand variation of loads in the power gride

the main auxiliary equipments and systems of units in largescale power plant under different loads aren't fully the same. The average plant service power consumption rate of four 360 MW units in Huaneng Luohuang Power Plant is about 9.5%. Through changing operation mode of feedwater system and circulatingwater system under low load condition of the units

the average plant service power consumption rate of said power plant has been reduced more than one point of percentage after retrofit

the powerproduction cost of said power plant being lowered.
