Abstract :
In this paper, a method of estimating the voltage distribution among the windings of an inverter fed random wound induction motor supplied through feeder cable is presented. The inverter-cable-motor model is developed, and the transient analysis is performed using ATP (Alternative Transient Program) package to estimate the voltage distribution among the motor windings. The high frequency parameters of the induction motor are calculated using field analysis and the parameters of the cable are computed using the Cable Constants routine in the ATP package. Using these parameters, a high frequency equivalent circuit of the inverter-cable-motor model is formed in ATP which is then used to estimate the voltage stresses at the motor terminals and the motor windings. Using this model, the effects of cable length on the voltage distribution among the motor winding is analyzed and discussed. In order to check the validity of the model, simulation results are compared with the experimental results. The proposed model is a general purpose model and hence can be used for detailed transient analysis with different configurations of the cable and terminal filters
