Chapter 2

AC Machine Modeling

Abstract

This chapter focuses on the dynamic modeling of induction machines. Two types of induction machine models are presented: space vector-based model and complex vector-based model. Type-3 wind generator, or doubly-fed induction generator, is an induction generator with rotor side connected to a converter. This chapter focuses on the modeling of the electric machines. Two examples are discussed in the chapter. In the first example, complex vector-based model is used for dynamic simulation of free acceleration of an induction generator. In the second example, space-vector-based model is used to examine the effect of stator voltage dip on rotor voltages.
