摘要
讨论了非正弦电流电网功率因数的定义和测量方法,指出在具有非正弦电流电网中,用传统有功电能表和无功电能表读数来计算平均功率因数的误差已不可忽视。
The paper deals with the definition and measurement method of power factor in a non-sinusoidal AC electric network.Under this condition,the error of average pow-er factor,calculated by using conventional active and reactive power meters,cannot be neglected.
