TRANSIENT ANALYSIS OF THREE PHASE INDUCTION MACHINES USING THE D,Q TWO-AXIS THEORY AT TWO DIFFERENT REFERENCE FRAME SPEEDS (STATIONARY AND SYNCHRONOUS)

Electrical

Abstract

Induction machines modeling has continuously attracted the attentions of researchers not only because such machines are made and used in larger numbers i.e. (80% of all the electrical loads), but also due to their varied modes of operation both under steady state and dynamic state. The theory of reference frames has been effectively used as an efficient approach to analyze the performance of the induction electrical machines.
In this paper a generalized model of a three phase induction motor is implemented (arbitrary reference frame), two speeds reference frames were used (synchronous and stationary), it uses case studies to demonstrate that the choice of the reference frame speed depends on the problem to be solved.
