1E级异步电动机非常情况下起动特性研究

A Study for Starting Performance of 1E Induction Motors Driving Pump & Fan

缩短起动时间、限制起动电流对核电站配泵、风机异步电动机来说非常重要．本文对处于非常情况下的泵、风机用１Ｅ级散嵌绕组异步电动机的起动特性进行了仿真研究．采用本文介绍的数字仿真不仅可对核电站配泵、风机异步电动机的起动特性进行精确的验证计算与分析，还可预测其行为特性，并可通过计算机自动修改设计参数而使其具有所需的理想特性．

Starting performances, especially starting period and starting current, are veryimportant characteristics for an induction motor driving pump or fan in nuclear electrical station. The paper presents a method for calculating the starting performance of 1E inductionmotors driving pump and fan under an unusual situation. The digital simulation introducedin this paper can be used to analyse and calculate starting characteristics exactly.
