摘　　要：节能环保是国内外船舶的绿色发展道路.特别体现在海洋工程船的大型施工设备和施工设备的变频电力驱动技术上.简述了海洋工程船舶电网的谐波抑制思路,介绍一种谐波抑制的具体方案——3次谐波注入的高功率因数变流器,探讨了高功率因数无源变流器的设计电路,包括桥前采用3次谐波注入的高功率因数三相无源变流器的电路拓扑结构,并利用MATLAB 7.0/SIMULINK 6.0搭建了其仿真模型.仿真结果表明,使用3次谐波注入的高功率因数变流器既能对输入电流具有一定的谐波抑制效果又能提高功率因数.For the purpose of energy saving and environmental protection,there is the more advanced development on the green roads of ships at home and abroad. Especially this is embodied in large-scale construction equipment of ocean engineering ships and the drive system to construction equipment. The ideas about harmonic suppression in electric propulsive shipping system are summarized. The paper analyses the harmonic suppression methods and related technology,specially emphasizes high power factor rectifiers based on triple harmonics injection. Also,the paper discusses the rectification circuits of high power factor rectifiers,including the three-phase high power factor rectifiers based on triple harmonics injection. And the simulated models are given by using MATLAB 7. 0/SIMULINK 6 . 0 . The results of simulation show that application of the three-phase high power factor rectifiers based on 3 rd harmonics injection in electric propulsive shipping system can suppress current harmonics and enhance the power factor.
