南上座泵站最优补偿功率因数分析

Analysis of optimum compensation power factor about Nanshangzuo pump station

从提高泵站运行效率的观点 ,结合宝鸡峡南上座泵站机组的实际资料 ,对该泵站异步电动机组进行补偿分析 ,找出了功率因数与无功补偿容量、投资变化率及投资回收年限之间的关系。结果表明 ,在南上座泵站 ,异步电动机组功率因数补偿到 0 .94时最为经济。

In view of raising the operational efficiency of the pump station and combined with the actual data of the units of Nanshangzuo pump station in Baojixia irrigated area,the compensating analysis is completed to the asynchronous motors of the pump station.The relations between power factor and reactive compensating capacity,investment change rate as well as investment payback period have been established,the result illustrates that the operation cost is the cheapest when power factor of the asynchronous motors is compensated and increased to 0.94.
