Abstract

Grid voltage sag causes typical transients in the generator electromagnetic torque, which result in significant stress on the wind turbine drive-train. In this paper, a combination of different simulation packages, namely FAST (Fatigue, Aerodynamics, Structure, Turbulence) and Simulink, is used to model the mechanical and electrical aspects of a 5-MW doubly-fed induction generator (DFIG) based wind turbine respectively. To reduce the mechanical loads induced by grid faults, a linear-quadratic regulator (LQR) based generator torque controller is presented. Simulation results showed that the active damping controller can effectively suppress the vibration of drive-train during fault ride through (FRT).
