大功率中压电机的启动分析与校验

Start-up Analysis and Calibration of Medium Voltage Motor with High Power

对电动机进行启动校验,按照不同项目电网条件选择合理的电动机启动方式,是工程电气设计的主要工作之一。文章结合建设在山区的冶炼企业小型电力系统,围绕如何解决大功率中压电动机的启动问题,进行电机启动计算分析,并应用ETAP电气计算分析软件对该电机启动进行仿真分析,提出了应对该小容量电力系统的电动机启动解决方案。

It is one of the main tasks of electrical engineering design to check the starting of motor and select a reasonable starting mode of motor according to the power grid conditions of different projects.Combined with the small power system of smelting enterprises built in mountainous areas,this paper focu-ses on how to solve the starting problem of high-power medium-voltage motor,carries out calculation and analysis of motor starting,and uses ETAP electrical calculation and analysis software to simulate the mo-tor starting,and puts forward a solution to the motor starting of this small-capacity power system.
