DESIGN OF A 500 KW DOUBLY FED INDUCTION GENERATOR FOR WIND TURBINE APPLICATIONS

Doubly fed induction generators are widely used in wind turbines. In this study, design concepts of doubly fed induction generator with 500 kW power for wind turbine applications is presented in detail. Firstly, the main dimensions and the winding structure of the generator are calculated analytically depending on predefined design criteria and performance values. Then, the improvements are performed on the analytical design by performing magnetic analysis. Structure, design factors and constraints of wind turbine generator; nominal working speed and power are investigated. The analysis results have shown that the designed generator satisfies the desired power specifications and design performance criteria.
