摘要
尽管三相不对称下功率因数定义已有多种公式,但在非正弦波形又不对称下的功率因数定义依然存有争议。本文从单相非正弦波形下无功功率的时域分析定义出发,导出三相不对称时视在功率的公式,从而获得非正弦波形又不对称下三相功率因数的计算公式。
Although there are some formulas for power factor in three phase asymmetric conditions,but the definition of power factor both in nonsinusoidal and asymmetric conditions is still questionable.In this paper,with domain analysis method for reactive power in nonsinusoidal,the formulas of apparent power and power factor both in nonsinusoidal and asymmetric conditions are describled.
