Abstract
The conventional method of analysis of Asynchronous machine fails to give accurate results especially when the machine is operated under high rotor frequency. At high rotor frequency, skin-effect dominates causing the rotor impedance to be frequency dependant. This paper therefore presents an improved method of modelling skin-effect in asynchronous machine under dynamic condition. The computed results are compared with the conventional model. The differences in the comparison underscore the need for the proposed model.KEY WORDS: Conventional method, Skin-effect, Rotor impedance, Asynchronous machine, Simulation.
