A NEW METHOD FOR ELIMINATING HARMONICS OF ELECTRIFIED RAILWAY WITH HYBRID FILTER BASED ON THE FUZZY OPTIMIZING DESIGN

A new method based on the fuzzy set and fuzzy optimizing theory that solves the problem of optimizing arrangement of hybrid filter scheme composed of type C filter in series with active power filter is presented in this paper. Mathematical model of fuzzy optimizing and the corresponding algorithm are presented for the multi aim optimizing problem of eliminating harmonics and reactive power compensation of electrified railway. The calculation results of one traction station as an example show that this method possesses the superiority of saving investment, raising the power factor and restraining harmonics effectively. It is an ideal method for eliminating harmonics and reactive power compensation of electrified railway with hybrid filter scheme composed of type C filter and active power filter.
