摘要
采用三相异步电动机在αβo坐标系下的数学模型,根据具体定子绕组接线的不对称情况,推导出电机定子端电压的约束条件。编写了一个适合于异步电动机对称和定子不对称运行情况的实用仿真计算程序,通过实例对定子Y形接法三相异步电动机的两相短接制动、倒拉反接制动和能耗制动运行过程进行仿真计算,并对仿真结果进行比较分析,得出了一些有用的结论。
According to the mathematical models of 3-phase asynchronous motor in αβo coordinates, considering stator terminal voltage constrains of stator symmetrical and asymmetrical conditions, the practical simulation program is written which applies to 3-phase induction motor symmetrical and stator asymmetrical operating cases. The program is applied to simulate stator two phase short connected braking, plugging braking and dynamic braking operation process of 3-phase asynchronous motor with Y-connected stator winding through a real calculation example and simulated results are also comparativly studied here.
