摘　　要：电力推进船舶电网的谐波问题日益突出和严重,简述了抑制谐波的思路和主要途径,探讨了船舶电网谐波抑制方案及相关技术,主要从高功率因数变流器、无源滤波器、有源电力滤波器3个方面进行讨论,其中包括多相整流技术、脉宽调制(PWM)整流技术和功率因数校正(PFC)技术,并给出了它们在船舶电力推进系统中的应用案例.The massive application of power electronic technology on electric propulsive ship has also caused harmonic problems, and the problems have become more and more serious. This paper introduces the harmonic suppression ideas and methods and discusses the harmonic suppression project and related technology, focusing on the power factor converter and the passive filter and the active electric power filter, which includes the heterogeneity rectification technology and the rectification technology of the Pulse Width Modulation （PWM） and Power Factor Correction （PFC） technology. And the cases of applying these harmonic suppression methods in marine electric propulsion system are also provided.
