Consideration of Current Displacement in Rotor Bars of Soft Starting Induction Machines

摘要

This paper deals with squirrel cage induction machines and their modeling concerning the appearancernof current displacement in rotor bars. In non-steady-state operation such as direct on-line start this effectrnhas to be considered. Also in the case of sustaining non-steady-state operation, e.g. by using softrnstarters (thyristor controlled AC voltage regulator), an accurate calculation of current and torque is required.rnDifferent calculation methods are pointed out and an appropriate calculation algorithm for implementationrnin MATLAB is described. Simulation results demonstrate the benefit of this model in conjunctionrnwith soft starters.
