Ha. Toliyat et al., Estimation of voltage distribution on the inverter fed random wound induction motor windings supplied through feeder cable, IEEE EN CON, 14(4), 1999, pp. 976-981
In this paper, a method of estimating the voltage distribution among the wi
ndings of an inverter fed random wound induction motor supplied through fee
der cable is presented. The inverter-cable-motor model is developed, and th
e 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 fiel
d analysis and the parameters of the cable are computed using Cable Constan
ts routine in the ATP package. Using these parameters, high frequency equiv
alent circuit of the inverter-cable-motor model is formed in ATP which is t
hen used to estimate the voltage stresses at the motor terminals and the mo
tor 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 hen
ce can be used for detailed transient analysis with different configuration
s of the cable and terminal filters.
