چکیده
This paper presents system stability analysis of DFIG based wind energy conversion system. Presently for variable wind speed DFIG is considered as efficient machine to generate the power. In addition to this advanced AC/DC/AC converters with closed loop control system has been presented. For stability analysis 1.5MW wind turbine has been considered. As the speed of the wind varies by ± 18% to 20% the voltage generated will also varies by ± 18 to 20%. With the aid of precise converter design it is possible to achieve stable output at the grid. From the simulation results it has been found that the method of achieving stable output at the grid is best suitable for wind energy conversion system.

Analysis and simulation of dynamic performance for DFIG-based wind farm connected to a distrubition system
Local renewable resources such as wind and solar are often available in remote locations. Wind farms consist of many individual wind turbines which are connected to the electric power transmission network. A wind farm can use the wind resources from a certain area efficiently. Double-fed induction generator (DFIG) is a generating principle widely used in wind turbine (WT). DFIG are ab...
