Sub-band RMS and power measurement principle and algorithm based on wavelets were introduced firstly, and then Dmeyer wavelet-based RMS and power measurement method was proposed. After that three other wavelet measurement approaches were compared with Dmeyer wavelet measurement method. Analysis results show that Dmeyer wavelet-based approach has high measurement accuracy either in total frequency band or in sub-bands. In addition relations of energy leakage characteristic of wavelet filter banks and measurement errors were deeply researched from the points of amplitude frequency property and energy leakage of wavelet filter banks. Finally,the influence was discussed, which was caused by the phase-frequency characteristic of wavelet filter banks in the practical application of power measurement algorithm.

介绍了小波变换有效值与功率分频带测量的基本原理与算法,提出了Dmeyer小波变换有效值与功率的测量方法,并对该方法与3种已经提出的小波测量方法的测量误差进行了对比分析,结果表明在各频率子带和总频带上,Dmeyer小波测量方法都具有较高的准确度。此外,本文还从小波滤波器组的幅频特性和能量泄漏的角度出发,深入研究了小波滤波器组的能量泄漏特性与测量算法误差之间的关系。最后,本文还讨论了小波滤波器组的相频特性对其在功率测量算法的实际应用中可能带来的影响。
