For a wide areas wind farms,that composed of many connected zones of different wind turbines and different generators, this book aims to study , model , and simulate of a wind farm model that includes a wind turbine and three different types of generators. The proposed generators are , three phase synchronous generator, three phase squirrel-cage induction generator and three phase doubly-fed induction generator, these generators are the main machines that generally used in the field of wind energy generation. All generators are connected in parallel at the point of common coupling (pcc) and connected to the utility grid. Different line faults are simulated, and wind power system stabilization is achieved using pitch controller. Several experimental results were taken and discussed in this book.
