Electric Machines and Power Systems

3.1 Introduction

Electric machines are necessary for electric power generation. Wind energy is captured by the wind turbine, which acts as the prime mover of the wind generator. Although induction machines are mostly used as wind generators, synchronous machines are also used as wind generators, especially for variable speed operation. Therefore, to understand the wind generator systems, the study of electric machines is necessary. Again, power generated by the wind energy system is connected to the power grid through transformers. Circuit breakers are located on the lines to respond to the fault situations. As a whole, it is essential when studying wind energy systems to have a basic understanding ...
