The use of the Doubly-fed Induction Generator (DFIG) in large wind turbines is growing rapidly, the wind farms are today required to participate actively in grid operation by an appropriate generation control. The study focuses on the direct power control (DPC) of the DFIG active and reactive powers (DPC) using the so-called sliding mode control (SMC). A model has been developed, including the mechanical,...
A novel direct power control of three-phase PWM rectifiers with constant switching frequency using fuzzy logic controller for space-vector modulation (fuzzy DPC-SVM) is proposed in this paper. The errors of active and reactive powers are the inputs of fuzzy controller and switching times are the outputs of controller. Line voltage sensors are replaced by a virtual flux estimator. Fuzzy DPC-SVM has...
