摘要
将小波变换方法应用于电力系统谐波检测中,用仿真算例说明该方法具有一定的有效性和可行性;用不同的小波函数进行了基频分量提取,给出了误差比较结果,初步分析了小波变换用于谐波检测时产生误差的主要原因.
Based on the wavelet decomposition, ways and means of detecting fundamental component and harmonics are explored. The simulation results show that the method is valid to a certain extent. In addition, simulation examples are cited in illustration of the error when the fundamental component is extracted by use of the wavelet decomposition. After the analysis of the frequency domain characteristics of several wavelet functions, the main causes of yielding error in harmonics measurement based on the wavelet transform are pointed out.
