Stability enhancement of DFIG wind turbine using LQR pitch control over rated wind speed
conference contribution
posted on 2016-06-01, 00:00 authored by K Islam, W Shen, Apel MahmudApel Mahmud, A Chowdhury, J ZhangA novel pitch control design method is proposed for the doubly fed induction generator (DFIG) wind turbine (WT) using linear quadratic regulator (LQR). A seven-order model represents the DFIG WT which is linearized by truncated Taylor series expansion. A systematic approach is adopted to determine the weighting matrices in LQR design for the optimal solution. Simulations have been carried out to compare the performance of the proposed LQR pitch control method against a PI pitch control for small and large disturbances. It is shown that the proposed control method enhances low-voltage ride-through capability and improves system damping under large disturbances.
