【摘要】 以泵站节能的观点 ,对宝鸡峡北昌泵站异步电动机组的无功补偿容量进行了分析计算 ,找出了该站无功补偿容量与功率因数、投资变化率及年电费回收率之间的关系。结果认为 ,在北昌泵站采用单机补偿方式运行时 ,无功补偿容量定为 70 k V最为合理更多还原

【Abstract】 In view of energy saving in the pumping station,the reactive compensating capacity of asynchronous motors in Beichang station of Baojixia is analysed and calculated in the paper,the relation between reactive compensating capacity and power factor,rate of investment adjustment and recovery ratio of annual power expenses is found out.The result shows that the reactive compensating capacity is very reasonable with operation mode of single machine compensating.Its capacity is 70 KVar.更多还原
