自适应形态学滤波器在HAPF中的应用研究
Study on application of adaptive morphological filter in HAPF
摘要
Abstract
To improve the performance of HAPF, it is very important to detect the harmonic currents fast and accurately.Based on the comparison of various methods of harmonic detection, this paper puts forward an adaptive morphological filter based on instantaneous reactive power theory, which uses adaptive morphological filter instead of LPF based on the traditional αβ and dq transformation.The new method uses adaptive algorithm to adjust the size of structure element of morphological filter dynamically.It not only preserves the merits of instantaneous reactive power theory, but also has advantages of easy and fast morphology operation and accurate adaptive algorithm.Matlab/Simulink is employed for the simulation study of this method.The results of simulation prove that the method is rapid, accurate and practical.关键词
