摘要：柴油机电力推进系统用推进电动机在直接起动时会产生很大的冲击电流，会引起电动机的发热损坏，且受电源系统总功率限制无法完成起动，因此需要对推进电动机进行软起动。本文以某船柴油机电力推进系统为例，在matlab simulink软件中建立仿真模型，研究推进电动机软起动时的性能。

Abstract：If the propulsion motor used in the diesel-engine driven electric propulsion system starts directly, a strong shock current will be produced, causing the electric starter motor being damaged when the motor gets heated. Furthermore, the total power of the electric source system may make it fail to start. Soft start is needed for the propulsion motor. Taking the electric propulsion system as an example, the paper built modeling to do researches on soft start performance of the electric motor with Matlab simulink.
