| 摘 要： | 针对船舶电力推进系统严重的电磁干扰问题,对系统传导电磁干扰进行了预测分析。通过分析传导EMI传播途径,建立整流器差模干扰等效电路和共模干扰等效电路,并以此为例建立了系统电网侧差模干扰模型、电网侧共模干扰模型、电机侧差模干扰模型和电机侧共模干扰模型。提出了基于双重傅里叶积分法的空间矢量脉宽调制波形解析建模方法,提高了电磁干扰预测分析精度,并考虑了电机高频模型的影响。最后,通过对一功率为10MW船舶电力推进系统传导电磁干扰仿真,对系统传导电磁干扰进行了预测分析,具有重要的工程应用价值。

| Abstract: | Aiming at the serious electromagnetic interference of the electric propulsion system,the conducted electromagnetic interference of the system was predicted and analyzed.The electromagnetic interference models of the system were built,which included the differential mode interference on the wire side;the common mode interference on the wire side,the differential mode interference on the motor side and the common mode interference on the motor side,respectively.The analytic method based on double fourier integral method was proposed to analyze the space vector modulation wave to increase the analysis precision.Besides,the influence of the high frequency model of the motor was also considered.Finally,the conducted electromagnetic interference of a 10MW electric propulsion system was simulated.And the conducted electromagnetic interference was predicted and analyzed based on the simulation results. |
