Method of Harmonic Reduction for Large Electrolyzer Facility using 6-Pulse Converter

6펄스 컨버터를 사용한 대용량 전해조 설비의 고조파 저감기법

To improve the power factor and reduce the harmonic contents of the system, the design of tunned filters for six-pulse thyrister converter which is used by electrolyzer system is discussed in this paper. Tunned filters are added to high-power rectifiers to keep the line current distortion within allowable limits and to improve the rectifier power factor. For electrolyzer system, the design procedure of tunned filters of AC 14.4kV power system are proposed by dynamic simulation. It is shown that these harmonic filters can meet most operational requirments. The the proposed design procedure is verified with the simulation and experimental results.
