This deals with the separation of the insulation model from the coil ladder network model in order to obtain the insulation losses of the coil in fast transients. Ladder network model or RLC Ladder Network (RLC) is introduced as a coil fast transient model for studying fast transient phenomena at high frequencies. In this study, the coil insulation model is separated from the RLC model and all circuit relationships related to this model are rewritten. The electrical parameters of the insulation are calculated by the substitution method in the resonant circuit. The single-phase windings of the 6KV induction machine are modeled with the help of the proposed model and by simulation in the Ansys Maxwell software; the voltage distribution waveform, the insulation loss coefficient, and the insulation loss at different points of the wire are shown. In the following, the voltage distribution waveform of the nodes, the current passing through the coils, the voltage on the coils and the power losses in the coils are compared by two classical RLC models and the proposed model. In this study, according to the separation of insulation losses from winding losses in fast transients and at high frequencies, the proposed model can be used as a suitable tool to achieve more accurate responses of fast transient phenomena. |
