Abstract: Dynamic modelling approach is the easiest method used to describe an induction machine. Dynamic model gives information about transient behaviour of the system. In this paper, the dynamic model of the induction motor is represented in state space using Krause modelling equations. Synchronous reference frame is used to develop a model and flux equations are expressed in terms of reactance. The equations are grouped and for each group a subsystem is developed. Initially d-q modelling method is used for modelling of healthy induction machine. The result is simulated using MATLAB/SIMULINK.
