With improved generator and turbine designs, better control techniques and low environmental impact, wind energy has emerged as a potential source of bulk power across the globe. In this paper, the authors report on the development of a variable speed controller for a doubly-fed induction generator (DFIG) based wind energy conversion system (WECS). DFIG is preferred as the generator because of several...
With increased penetration of wind power into electrical grids, doubly-fed induction generators (DFIGs) are largely deployed as the electric generator for wind energy conversion systems (WECSs) to their robustness and easy controllability. In this paper, the authors report on the development of a model of a grid-connected DFIG-based WECS for studying its dynamic behaviour during grid disturbance....
In recent years, there is a strong trend towards generation of wind power across the globe in geographically suitable areas with a more or less stable wind velocity. The wind farms employ Doubly-fed Induction Generator (DFIG) for energy generation. DFIG allow active and reactive power control through a rotor-side converter, while the stator is directly connected to the grid. Rapid and widespread development...
In recent years, there is a strong trend towards generation of wind power across the globe in geographically suitable areas with a more or less stable wind velocity. However, the erratic nature of wind velocity as a power source is leading to problems of voltage/frequency oscillations and stability in wind energy conversion systems (WECS). Therefore, extensive research is being carried out for efficient...
