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

Improving fault ride through capability of DFIG during RSC flashover fault [PDF]
2013 IEEE International Conference on Smart Energy Grid Engineering (SEGE), 2013 Wind power generation is growing rapidly. However, maintaining the wind turbine connection to grid is a real challenge. Recent grid codes require wind turbines to maintain connected to the grid even during fault conditions which increases concerns about its sensitivity to external faults. So, researchers have given attention to investigating the impact
