计及机械损耗与饱和影响的感应电动机仿真

SIMULATION OF INDUCTION MOTOR INCLUDING MECHANICAL LOSSES AND SATURATION

本文分析感应电动机的四种动态模型，即１．理想电机模型；２．计及励磁电抗Ｘ＿ｍ饱和影响的电机模型；３．计及机械损耗的电机模型；４．同时计及Ｘ＿ｍ饱和与机械损耗的电机模型。借助于时变的非线性方程组，通过一定简化、假设，得出电机的动态特性的仿真结果。对仿真结果与实验结果的比较，证实了动态分析是正确的。

Dynamic analysis of induction motor in four cases is presented in thispaper,These four cases are 1. ideal motor;2.taking into account the satura-tion of magnetisation reaction 3.considering the mechanical losses; and 4.tak-ing into account both saturation of X_m and mechanical losses.The machinedynamics are presented by a set of non-linear time-varying differential equa-tions and solved by some simplifying assumptions.To validate the approach,simulation results are compared with experimental study conducted in labo-ratory.
