摘要
A numerical simulation of the inverter surge is carried out using a frequency-dependent model of a cabtyre cable. The frequency-dependent model is based on the Semlyen line model in the EMTP, for which the required parameters are determined from the measured results of the wave propagation characteristic in the cable. A simple model of an induction motor is proposed considering resonances in the motor. The simulated result by the EMTP agrees reasonably well with the measured result. The proposed model can be useful for predicting the peak voltages observed at the motor terminal of inverter-operated motors.
