摘要
En 中文
This paper proposes a novel model for the starting simulation of induction machines (IMs) where its dynamics are computed directly from the impulse response produced by finite element analysis (FEA). This model realizes an accurate starting simulation owing to considering the skin effect of the cage rotor winding, which cannot be entirely represented by the conventional equivalent circuit model even if several auxiliary branches are added on its rotor side to reduce the modeling error in the high-frequency region. Furthermore, the dynamics can be computed by simply executing the convolution integral for the impulse response and input voltage. In other words, the model requires no fitting or approximation to determine the equivalent circuit parameters, which has been studied extensively in many kinds of literature. For the starting characteristics as an example, the accuracy of simulations using the model was investigated thorough comparing its result with that of measurement and FEA. These researches demonstrated that the proposed model provided a remarkable improvement for the starting simulation.
