| Abstract: | This paper analyzes the principle of four kinds of harmonic wave filter technologies with the Linearity neural networks,LMS,RLS and Wavelet transform in electric power frequency communication system and figures out the range of using four filter methods.Through four methods to filter the three times harmonic wave by 500 Hz voltage distorted wave form,the paper emulates the filter result with MATLAB software,and at last,it is considered that linearity neural networks is the best method after comparison. |
