摘　　要：对船舶电力推进用同步发电机-推进变流器系统的电压畸变进行了量化分析,建立了该系统的Matlab/Simulink仿真模型,对负载为线性和非线性的两种工况进行了仿真分析,从而确定同步发电机-推进变流器系统中的谐波特性,并针对系统中存在的谐波提出了抑制总谐波及单次谐波畸变的方法.最后,对比分析了仿真谐波畸变值和IEEE标准中规定的畸变值.Voltage distortion of the synchronous generator - propulsion converter system in electric propulsion is analyzed. Based on the software Matlab/Simulink, a simulation model of the system is founded, which simulates the two working conditions of linear load and nonlinear load. Then the harmonic characteristics can be confirmed. For the harmonic wave in the system, it finds out the method to suppress the THD and the single harmonic distortion. The simulating harmonic distortion result is compared with the standard in IEEE.
