依据铭牌数据估测出电动机单笼模型仿真参数的方法,未考虑磁饱和、温升等影响,参数精度不高,造成电力系统稳定分析误差偏大。基于 PSCAD/EMTDC、EMTP、BPA 等不同感应电动机模型,仿真分析比较电力系统特性参数,结果表明：PSCAD 提供的 EMTP 模型能够比较精确地模拟电动机的运行特性,BPA 能够正确反映暂态过程中负荷的功率变化趋势,但对于负荷动态的模拟精度有一定误差。

The estimation method of simulation parameters for single-cage motors based on the nameplate parameters does not consider the influences of magnetic saturation,temperature rise and so on.The accuracy of parameters estimation is not high enough,and the stability analysis for power system has large errors.This paper compared the power system dynamic characteristics with difference load models of induction motor,such as PSCAD/EMTDC、EMTP、BPA.Results showed that the EMTP model of PSCAD/EMTDC platform can simulate the motor operation characteristics with high accuracy,and the BPA can simulate the load power changing direction with some error.
