This paper presents a control method that reduces the pulsating torque and dc voltage problems of a Doubly Fed Induction Generator (DFIG)-based wind turbine system. To reduce the torque and the power ripple, a current control scheme, consisting of a proportional integral (PI) controller, is presented in a positive synchronously rotating reference frame and is capable of providing a precise current...
This paper presents the implementation of a direct active and reactive power control of a doubly fed induction generator (DFIG) applied to a wind generation system as an alternative to the classical field oriented control (FOC). The FOC is known to have complex control structure, which consists of current controller, power controller and frame transformations, and also depend highly on parameter variation...
The original direct power control (DPC) is known to give a fast response under transient conditions. However, active power, reactive power and current pulsations occur in steady-state operation. A family of variable structure controllers for the doubly fed induction generator (DFIG)-based wind turbine system is presented, using the principles of an active and reactive power controller known as modified...
