摘　　要：以大功率高压异步电机的启动方式为研究对象,结合某煤化工项目的实际工程数据,探讨了大功率高压异步电机启动方式的选择原则和步骤,通过对变压器-电机组全压直接启动和晶闸管串联式高压软启动两种启动方式的综合比选,确定了推荐方案,总结出了适用于工程设计的大功率高压异步电机启动方案选择的工作流程。Taking the starting method of high-power high-voltage asynchronous motor as the research object,combined with the actual engineering data of a coal chemical project,the principles and steps of selecting the starting method of high-power high-voltage asynchronous motor are studied.The comprehensive comparison of the two starting methods of starting and thyristor series high-voltage soft starter has determined the recommended scheme,and summarized a set of workflows for the selection of the starting scheme of high-power high-voltage asynchronous motor suitable for engineering design.
