Wind turbine control design to enhance the fault ride through capability [PDF]
IET Conference on Renewable Power Generation (RPG 2011), 2011 This paper presents a control strategy for wind turbines to enhance their fault ride-through capability. The controller design is based on pitch controlled variable speed wind turbine equipped with doubly-fed induction generator (DFIG). The fault ride-through is realized by injecting a crowbar with variable resistance on the generator rotor circuit. To
