船舶电网系统对电流质量有较高的要求,而多脉冲变压整流技术可有效降低输入电流中的谐波含量。在详细分析12,18,24三种多脉冲变压整流器工作原理的基础上,在Matlab/Simulink中分别搭建多脉冲变压整流电路的仿真模型,并对3种多脉冲变压整流电路的仿真波形进行对比分析。仿真波形说明,多脉冲变压整流技术可以有效地降低输入侧的电流谐波含量,很好地抑制特定次数的谐波,进而提高船舶电网的稳定性。
The ship electric propulsion power network has higher requirement for current quality and multi-pulse rectifier can reduce the total harmonics distortion (THD) of the input currents. On the base of analyzing the principle of multi-pulse transformation rectifier in detail, three simulation models of multi-pulse transformation rectifiers are built in matlab/simulink. And the differences of 12-pulse, 18-pulse, 24-pulse transformation rectifiers and the performance of reducing the harmonics distortion of the input currents are compared from the simulation waveforms.
