In the presented work, a dynamic model is provided for the wound-rotor induction machines with short-circuited stator winding. Both inter-turn phase-to-ground and inter-turn phase-to-phase short circuit faults are considered in the provided model. The self- and mutual-inductances of the windings of the faulty machine are the parameters of the provided state-space equations. As well as the machine electromagnetic torque and its stator and rotor currents, the waveform of the unbalanced magnetic force (UMF) in the faulty induction machine is predicted in the provided model. The UMF of the faulty machine is expressed by a static function of the machine currents. The parameters of the UMF function are obtained by using the Maxwell definition. The machine inductances and the air gap flux density distribution are obtained by means of winding function method. Since the exact waveforms of the machine turn functions are considered in computation of the air gap flux density, the special harmonics are taken into account inherently in the provided model. Finally, the developed model is verified by means of the time-stepping finite element model.

匝间短路定子双馈感应电机不平衡磁力的动态仿真

在目前的工作中，为具有短路定子绕组的绕线转子感应电机提供了动态模型。提供的模型中考虑了匝间相对地和匝间相间短路故障。故障机器绕组的自感和互感是提供的状态空间方程的参数。除了电机电磁转矩及其定子和转子电流外，还可以在提供的模型中预测故障感应电机中的不平衡磁力 (UMF) 波形。故障机器的 UMF 由机器电流的静态函数表示。UMF 函数的参数是使用 Maxwell 定义获得的。电机电感和气隙磁通密度分布是通过绕组函数法获得的。由于在计算气隙磁通密度时考虑了电机匝函数的精确波形，因此在提供的模型中固有地考虑了特殊谐波。最后，通过时间步长有限元模型对开发的模型进行验证。
