Fast Methods for Speeding up the Induction Machine Simulation

Abstract

In induction machine simulation, it usually takes quite a long time to reach the steady state due to the large time constant. In this paper, two methods are proposed to speed up the transient process to reach the steady state. In both methods, the initial condition of the simulation is estimated from the solution of FEA model with locked rotor and equivalent conductivity/resistance. The effectiveness of the methods is validated by two examples with the comparison of the performance between two methods.
