This paper investigates modeling improvement of cage induction machines (CIMs) in fast transients. In this method, RLC ladder network model associated with each turn of the coil is employed as the interface between voltage sources and finite element region. All circuit and field equations are rewritten to obtain final matrix of the system. The developed model opens a way to improve electrical machine simulators, on the basis of finite element method (FEM), to obtain a more accurate voltage distribution waveform at each turn of the coil in fast transients and to increase frequency validity of the modeled machine by RLC method using the FEM.

用于快速瞬态研究的笼型感应电机的改进模型

本文研究了快速瞬态中笼式感应电机（CIM）的建模改进。在这种方法中，与线圈每匝相关的RLC梯形网络模型被用作电压源和有限元区域之间的接口。所有电路和场方程都被重写以获得系统的最终矩阵。所开发的模型为基于有限元方法（FEM）的电机模拟器的改进开辟了一条途径，以便在快速瞬态中获得线圈每一匝的更准确的电压分布波形，并通过以下方法提高建模电机的频率有效性：使用FEM的RLC方法。
