Abstract

The rapid growth of wind energy need requires more efficiency in the produced energy. For fixed speed wind turbines, the connection of its squirrel cage induction generator to the grid leads to inrush current which can reach 1.5 p.u. up to 2.5 p.u. in higher wind speed. We propose in this paper a new soft-starting of squirrel cage induction generator based wind turbine connected to the grid. Our strategy overcomes such transient instability problems and pinpoints rapidly synchronous speed for each wind speed acting on pitch angle.
