摘要
利用准确的功率测量公式推导出一种不含不对称误差的三相无功功率计算方法,并采用单片机交流采样技术实现,通过对3种测量计算方法比较,证明这种计算方法是正确的,具有一定的实用价值.
This paper describes a new method to measure and calculate three phase reactive power,which derived from accurate formula and does not contain asymmetry error(caused by the asymmetrical voltages and/or currents).It has a certain application value,and the result is compared and manifested by alternative sampling experiment.
