Abstract
In time domain the asynchronous sampling is easy realized in hardware, but it leads to measurement error in energy measurement. Modified compound Simpson integral method is proposed to reduce the error. The computing formula is deduced. Ideal signals and distortion signals are simulated. Simulating results show the proposed integral method has the highest precision, compared with previous method, the precision is improved dramatically. The results also show the sampling rate has little influence on the measurement accuracy. So the new algorithm is practical and is easy realized by DSP.
