【Abstract】 One of main problems to block the broader application of marine electric propulsion is a lot of harmonic wave generated in marine electric power system. A brief description about the harm of the harmonic wave to marine electric power system is given, then the harmonic generation and the feature of harmonic wave in input current of the marine cyclo-converter are analyzed. Based on this, the methods for compensating the harmonic wave are discussed. At last, when trying to use cyclo-converter marine electric propulsion system, an active power filter has to be used; has to be considered when type selecting. Both of the marine electric propulsion system and the harmonic trap devices.更多还原
