Abstract

Considering the present electric energy measurement algorithm with the defect of low accuracy of measurement and unable to separate the fundamental wave and harmonic signal power when measurement the electric energy. This paper devises a fast and accurate electric energy measurement algorithm based on S-transform. Theoretical analysis shows that the S-transform can separate the signals into many components of different frequency, without the need for dividing the frequency band for many times to measure a harmonic component like wavelet packet algorithm, which greatly reduce the complexity of implementation and the subsequent error .In order to demonstrate the superiority of the method, this paper compares the results of the method based on S-transform algorithm with the measuring results of using the method of wavelet packet transform. Based on simulation analysis and experimental verification shows that, whether it is stationary or non-stationary signals signal, the measurement result of the method based on S-transform algorithm is greatly superior to the results which are obtained by wavelet packet transform.
