The Third Edition features end-of-chapter exercises with simulations and new applications with small hydro power plants. It shows how to include magnetizing inductance saturation in an induction generator (IG) transient model, discusses new electronic forms to minimize the self-excitation capacitors for stand-alone IGs, and compares IGs with doubly-fed IGs, permanent magnet synchronous generators, conventional synchronous generators, and others to aid in selecting a generator for a particular application. It also explores maximum power point tracking methods for IGs used with wind, Magnus, and hydro turbines.
