非正弦交流电功率计量误差的估算

Estimation of measuring error of electrical power for nonsinusoidal AC

介绍了估算智能瓦特表测量非正弦交流电功率误差的方法，它适用于各类晶闸管控制的非正弦交流电路．采用这一方法并用计算机计算，可较准确的算出电功率、电压和电流的误差．

A method to estimate error of measureing electrical power for nonsinusoidal AC with intelligent instrument is presented in this paper.It is useful to AC circuit controlled by SCR.Using this method and calculating by computer,the errors of power and voltage and current can be estimated accurately.
