Based on the theory of fuzzy sets and fuzzy optimization, a new method is proposed to optimize the configuration of a hybrid filter by using a C-type filter and an active filter in series. The fuzzy optimization mathematical model is established and the corresponding algorithms are proposed. In order to comprehensively solve the multi-objective optimization problem of harmonic and reactive power compensation of electrified railway. Taking a traction station as an example, the fuzzy optimization calculation is carried out. The results show that the proposed method has the advantages of saving investment, improving power factor and suppressing harmonics effectively. Is to use C-filter and active filter composed of hybrid filtering solution is to solve the electrified railway harmonics and reactive power compensation integrated approach an ideal method.
