Modeling and Simulation of Doubly Fed Induction Generator Driven by Wind Turbine

Environmental pollution and shortage of conventional fossil fuel are the two major concerns which have led to the global emergence of wind energy as an effective means of power production. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to the fixed speed wind turbines. These wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed wind generation system based on Doubly Fed Induction Generator (DFIG). This paper deals with mathematical modelling of doubly fed induction generator driven by wind turbine. The modelling procedure is briefly explained, mathematical descriptions and Simulink models of the wind power plant basic parts are shown and the model of the whole system is presented.
