Elimination of Resonant Internal Harmonics in Power Electronic Converters

Present electrical power system is polluted bycomplex harmonics generated by power electronic converters.Even though external harmonics are reduced by advancedfiltering techniques, still resonant internal harmonics createcritical behavior of power system. Resonant internal harmonics(RIH) are not identified by the present harmonic reductionmodels. A model is proposed to identify and eliminate resonantinternal harmonics produced by power electronic converters. Theproposed model has been tested through simulation on single andthree phase thyristor valve converters and the results thusobtained are prese
