摘要
当采用交流同步采样技术进行功率测量时由于频率变化,或电压、电流通道不能完全同步等原因将造成相位偏移,从而引起测量误差。本文提出了对这种相位引起误差的一种补偿算法。通过计算机仿真计算,给出了仿真计算结果,证明能有效地提高功率测量准确度。
The frequency is variety, the and other factors will cause the phase voltage and current path is non-synchronous shifting and the measurement error when using the AC sampling technology to process the power measurement. Present a error compensation algorithm, the error is caused by the phase. The simulation algorithmic results show the method increases the accuracy of the power measurement.
