Generation of Wind Power using Doubly Fed Induction Generator

Abstract

Due to independent controlling mechanism for the active and reactive power, doubly fed induction generator (DFIG) is still culled by the wind turbine companies. The control strategies are continuously advancing to manage the grid codes (i.e. reactive power compensation, low voltage ride-through operation). This paper focuses on the control strategies using combined reactive power compensation for power converters to maintain the optimized lifetime distribution under normal grid conditions. An advanced demagnetizing control is also discussed which maintains the minimum thermal stress of the rotor-side converter in case of the short-term grid fault. A modularized control strategy of the DFIG system under unbalanced and distorted grid voltage is also presented, which discusses the control targets of the smooth active and reactive power and balanced sinusoidal current of the rotor-side as well as the grid-side converter. In this paper, the limitations of control strategy implementation for wind turbines are also discussed.
