STABILITY ANALYSIS OF FIELD ORIENTED DOUBLY-FED INDUCTION MACHINE DRIVE BASED ON COMPUTER SIMULATION

ABSTRACT

This paper presents computer simulation of a field oriented controlled doubly-–ed induction machine (DFIM) drive system. Functions and simulation model of this system are given. Necessity of the gap flux open loop control is discussed. The damping characteristics of flux during variations of both power mains and machine load is simulated. Compensation method for increasing damping speed of flux oscillation is proposed. Both simulation and test operation show that the DFIM drive has a good performance which fulfill requirements of some high dynamic, low cost applications.
