大型船舶动力系统中，使用电力推进优势明显，但其工作时产生的大量谐波危害巨大。对于谐波问题，解决方法根据不同方向，可分为在电网中加入谐波滤波器和使用多相整流技术两类办法。其中，试图从谐波产生源头直接抑制谐波的多相整流技术已证明是最根本最有效的解决途径。本文重点介绍12相与24相整流技术原理，说明脉波数对抑制效果的影响。之后为了进一步验证，本文利用Simulink平台对搭载变频器的电动机进行仿真，分析12脉波变频器与24脉波变频器对谐波产生源的影响。最后获得使用脉波值越高的整流器谐波畸变率越低的结论。

In a large ship power system, the use of electric propulsion has obvious advantages, but the harmonic waveit produced dose great harm. For harmonic problem, solutions according to the different directions can be divided into two kinds of methods which are including the frequency harmonic filter and multiphase rectification technology. Among them, tried to suppress harmonic harmonic source from directly multiphase rectification technology has been proved to be the most fundamental and effective solution. This paper mainly introduces the principle of 12 and 24 facies rectification technology, the inhibition effect of the influence of pulse number. To further after verification, by using Simulink simulation platform for carrying inverter motor, respectively analysis a 12-pulse frequency converter and a 24-pulse wave transducer for the influence of harmonic source. Finally, it got the conclusion that the more pulse value of frequency converter is more effectivet in harmonic suppression.
