Harmonic characteristic simulation of the synchronous generator-propulsion converter system in electric propulsion

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2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。

In this paper,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.Simulate the work station under the load condition of different proportion of linear load and nonlinear load.Ascertain the main contents of the harmonic;find out the method to suppress the THD and the single harmonic.While compare the results with standard of IEEE.
