摘　　要：循环水泵是火力发电厂最主要的耗电设备,且长期连续运行;机组所需循环水量,不但受机组变工况运行的影响,同时还受昼夜温差和季节的影响;300MW机组的标准设计,均为两台定速循环水泵,循环水量的调整手段极其有限;对循环水泵电机进行改造,能满足寒冷季节和秋、冬季节低负荷的需要,对降低厂用电率有着显著效果,提高机组的经济性。Circulating water pump is a thermal power plant most to consume an electricity equipments,and the long-term circulate in a row ;The circulating amount of water that machine set need,be subjected to the machine set influence which changes work condition movement not only, in the meantime still be subjected to the influence of the difference in temperature and season day and night;The standard design of the 300MW machine set all is two sets to settle soon and circularly water a pump,circulating water quantity of the adjustment means is very and limited;To circulation the water pump electrical engineering carry on a reformation,can satisfy cold season and the demand of autumn,the winter stanza low burden,having to show result towards lowering factory with the electricity rate, raising the economy of machine set.
