A novel structure for maximum power extraction from a variable speed wind turbine driving an DFIG

In this paper, a novel structure for controlling speed and power of Double Fed Inductive Generators (DFIG) was studied and simulated, in order to maximum power extraction from a variable speed wind turbine. In this structure, direct current link of all convertors in rotor of inductive generators was connected and it is also coupled to the grid through a three-phase pulse width modulated convertor and transformers. Moreover, the number of convertors will be increased concerning to the typical DFIG wind turbines.
