摘　　要：现有电力推进船舶电网谐波抑制方法由于应用技术的局限性,存在着电压与电流波形畸变率较高的问题,因此提出OBE-CDIO模式下电力推进船舶电网谐波抑制方法。深入分析电力推进船舶电网谐波特性,以此为基础,选取变频器作为谐波抑制装置,并设计装置主电路,应用上述设计的12脉冲变频器主电路,在电力推进船舶电网谐波抑制中,将变压器设计为2组,2组整流桥产生的谐波可以相互抵消。实验数据显示:与现有方法相比较,提出方法电压与电流波形畸变率均较小,充分表明提出方法的谐波抑制效果更佳。Due to the limitation of application technology,the existing harmonic suppression methods of electric propulsion ship power grid have the problem of high distortion rate of voltage and current waveforms.Therefore,the harmonic suppression method of electric propulsion ship power grid under obe-cdio mode is proposed.Based on the in-depth analysis of the harmonic characteristics of the electric propulsion ship power grid,the inverter is selected as the harmonic suppression device,and the main circuit of the device is designed.Using the main circuit of the 12 pulse inverter designed above,in the harmonic suppression of the electric propulsion ship power grid,the transformer is designed into two groups,and the harmonics generated by the two groups of rectifier bridges can cancel each other.The experimental data show that compared with the existing methods,the voltage and current waveform distortion rate of the proposed method is smaller,which fully shows that the proposed method has better harmonic suppression effect.
