摘要：
Since the wavelet transform has many different kinds of advantages, it has widely been applied to detect harmonic waves in power system. In this paper, the basic principle of Mallat algorithm and anti-aliasing Mallat algorithm are briefly described, and their advantages and existing problems are analyzed in detecting harmonic waves. The analyzing results demonstrate that computing anti-aliasing Mallat algorithm is time-consuming. In consideration of the weakness, a new method of anti-aliasing Mallat algorithm based on fast Hadamard transform is proposed, and the simulation results demonstrate that the real-time performance improved by the method in power harmonic waves detecting.
