泵站机组功率因数提高方法探讨

Research on raising power factor of electric equipment in pumping station

针对中、小型泵站安装异步电动机拖动水泵运行中功率因数低，给电力系统带来无功损耗较大的缺陷。结合宝鸡峡南上座泵站装设机组的实际资料，采用配装同步电动机组进行无功补偿分析计算，对其配装同步机组容量作了探讨。指出在中、小型泵站选型设计时，采用配装同步电动机组容量与异步电动机组容量比小于０．３是比较经济合理的．

The instalation of pumps towed by asynchronous motors in middle and small size pumping stations causes great reactive-food consumption to the electric power pool with lower power factors. In this article,based on analysis of data collected from the pumping stations in Bac n Gorge irrigation District,the author put forward the ideal of compensating reactive--load consumption by installing some synchronous motors in the same pumping station. And make a further calculation on the installed capacity. Draw a conclusion,it is more economical to make the ratio of synchronous motor installed capacity to asynchronous motor installed capacity less than 0. 3 in the pumping station designing.
