摘　　要：本文通过研究油田中大功率异步电动机起动方式分析,不同起动方式对电动机本身、相邻设备、以及不同电压等级母线所造成的压降不同,利用EDSA仿真模拟电动机直接起动、软起动、变频起动三种起动方式,从理论和实际结果验证了选择软起动方式的必要性。Base on the study of large asynchronous motor start, this paper mainly talks about the different voltage drop caused by different start-up mode of MV motor to the motor itself, adjacent equipment, and different voltage grade busbar. Through the EDSA simulation of three start-up ways such as direct start-up, soft start-up and VFD start-up, analyzing the results, it draw conclusion that the importance of the soft start-up mode.
