Abstract

While variable speed operation of wind turbines has several advantages, it poses difficult challenges in the design of control systems. The purpose of this work is to present a nonlinear variable speed control method for wind turbines. This method is based on the regulation of excitation winding voltage of the generator. Based on both mechanical and electrical dynamics, a nonlinear control algorithm is derived which is able to achieve smooth and asymptotic rotor speed tracking. The effectiveness of the method is verified via computer simulation with varying operating conditions
