摘　　要：船舶电力推进变压器次级接有大量的高频开关设备,所产生的高频电磁噪声通过变压器的分布电容传递到初级的电网中,污染船舶电力系统。本文通过对高频电磁噪声传递路径和电力推进变压器分布电容的分析,提出了噪声抑制的方法,并通过有限元仿真和试验验证抑制方法的正确性。Many high frequency switchgears are connected with secondary winding of transformer used in ship electric propulsion. The high frequency electromagnetic noise generated by switchgears are transmitted through the distributed capacitance to power grid on primary side could pollute the marine power system. The article analyzes high frequency electromagnetic noise transmission path and electric propulsion transformer distributed capacitance, puts forward the noise suppression method. The finite element simulation and experiment proves that the suppression method is correct.
