Dynamic modelling and control of doubly fed induction generator variable speed wind turbine

Abstract

Tendency to erect ever more wind turbines can be observed in order to reduce the environmental consequences of conventional power generation. As a result of this, in the near future, wind turbines may start to influence the behavior of the power systems. Therefore, wind turbine models that can be integrated into power system simulation software are needed. Even more the wind farms are today required to participate actively in grid operation by an appropriate generation control scheme. In this paper, the modelling and dynamic behavior of a variable speed wind turbine with pitch control capability is explained in detail and the turbine performance characteristics are simulated in the MATLAB/SIMULINK. The paper also presents a comparative study on the performance of two control strategies for variable speed wind turbines. © 2011 Springer-Verlag.
