【摘要】 20世纪80年代中期以来，随着电力电子器件及交流电动机调速技术的进步，舰船电力推进迎来了一个蓬勃发展的新时期。从电力推进技术的国内外现状来看，电力推进将成为今后船舶制造产业的主流发展方向。基于船舶电力推进的各方面优势，我校211工程—船舶电力推进仿真实验室将投入人力、物力建立一个更完善的船舶电力推进系统。电力电子技术在船舶上的大量应用也带来了谐波问题，且日益突出和严重，国内外都发生过因谐波而引发的重大船舶事故。在我国，对有关电力推进船舶电网的谐波问题的研究还处于起步阶段。本文对电力推进船舶电网谐波问题以及已有的谐波抑制方法及相关技术进行分析和总结，并以MATLAB7.0软件包中的SIMULINK仿真环境为平台，进行相应的仿真研究，验证其有效性。并期望能对电力推进船舶电力网以及船舶电力推进仿真实验室的谐波抑制研究具有一定的参考价值。论文的具体工作包括以下几个方面：(1)阐述了谐波对船舶电网产生的影响和危害。(2)总结了船舶电网谐波抑制方法及相关技术，主要从高功率因数变流器、无源滤波器、有源电力滤波器三方面进行讨论，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。(3)结合多相整流器和功率因数校正(PFC)技术，进行了提高功率因数的电力变流电路仿真，其中包括高功率因数无源(PFC)变流器和有源(APFC)变流器。(4)详细说明了无源滤波器(PPF)的构成与分类，以及LC滤波器参数的确定；并通过分析采用三相谐波滤波器的仿真实例，说明了谐波滤波器的设计方法以及和优缺点。(5)讲述了有源电力滤波器(APF)的原理、分类以及研究动向，重点讨论了单位功率因数控制策略(UPF)的基本思想及其相应的控制方法，并建立了基于UPF算法的并联型有源电力滤波器的仿真模型，包括单相并联型APF和三相并联型APF的仿真分析。更多还原

Judging from situation of electric propulsion technology at home and abroad, marine electric propulsion will become the main developing direction in ship building. Owing to advantages of marine electric propulsion, manpower and material resources will be thrown into to build a more perfect marine electric propulsion system in marine electric propulsion simulation lab of project 211 of our university.The massive application of power electronic technology on ship has also caused harmonic problems, and the problems have become more and more serious. Many marine accidents have happened in the world due to harmonic problems. In China, the research on harmonics of marine electrical propulsion is at the start stage. This dissertation summarizes harmonic problems about power system of marine electrical propulsion, as well as the harmonic suppression methods.
