Flicker Reduction of Stall-Controlled Wind Turbine Using Variable Rotor Resistance

• In this paper, a flicker reduction control for stall-controlled wind turbines with induction generators, using variable rotor resistance, is derived. The objective is to reduce torque fluctuations and flicker emission by using a variable rotor resistance. However, the rotor resistance can only be varied within a limited range. This puts a limit to the achievable reduction in flicker emission and torque fluctuation which is investigated in this paper.
