摘　　要：对配电网传统无功功率测量中,由于电压、电流不对称引起的不对称误差进行分析,推导了无功功率在电压、电流不对称时的准确表达式,介绍了一种基于单片机交流采样技术消除不对称误差的准确的无功功率测量方法。This paper deduces the accurate expression of reactive power by analyzing the error resulting from the unsymmetry of voltage and current in reactive power measurement of power distribution network,and introduces an accurate reactive power measuring method removing unsymmetrical error based on single chip processor AC sampling technology.
