Solutions for Power Quality Issues of Wind Generator Systems

7.1 Introduction

Using wind power to generate electricity is receiving more and more attention every day all over the world. One of the simplest methods of running a wind generation system is to use an induction generator (IG) connected directly to the power grid, because induction generators are the most cost-effective and robust machines for energy conversion. However, induction generators require reactive power for magnetization, particularly during startup. As the reactive power drained by the induction generators is coupled to the active power generated by them, the variability of wind speed results in variations of induction generators’ real and reactive powers. It ...
