摘　　要：农网中交流异步电动机应用广泛,但不少异步电动机负荷率低,常处于轻载或空载状态,无功功率消耗比有功功率大,电能浪费严重。因此,提高功率因数是节约电能、减少运行费用的有效措施。对合理选择和使用异步电动机提高自然功率因数、就地补偿提高总功率因数等进行了论述。In the agricultural grid the asynchronous motors are widely applied,but many asynchronous motors load factor is low,often at idling or the light condition,reactivepower consumption is bigger than activepower,the power energy waste is serious.Therefore,the effective action of saving the power energy and reducing the operating cost is enhancing the power factor.This article elaborated the reasonable choice and the useful asynchronous motor to enhance the natural power factor,the compensation to enhance the total-output factor and so on.

关 键 词：自然功率因数 无功功率 就地补偿 补偿容量
