Simulation for Resistance-Capacitance Braking of Induction Motors with Semihex^(TM)-connected

根据SemihexTM接线方式和三相感应发电机的稳态等效电路,利用对称分量法导出SemihexTM联接单相感应电动机最小激磁电压下的阻容元件参数计算式,用最优化算法进行计算;建立了SemihexTM单相感应电动机在α-β坐标系下的瞬态数学模型,编制计算机仿真程序,通过实例对电动机带通风机负载时的阻容制动瞬态过程进行仿真计算.仿真结果表明:SemihexTM单相感应电动机的阻容制动适合于各类性质的负载,特别适合于具有摩擦阻尼性负载和轻恒转矩负载机械的制动停车.

The symmetrical components method was used to obtain the Resistance-Capacitance parameters formula of the SemihexTM-connection single phase motors on the basis of the static equivalent circuit of the three-phase generator,and then the optimization calculation was carried out.The instant mathematic model of the motors under theα-βcoordinate system was established,and the correspondent program was written to simulate the motor'Resistance-Capacitance breaking process with a ventilator load.The result has shown that this breaking method suits various types of load,especially those with a feature of friction damp or light and permanent torque.
