Mathematical modelling and simulation of wind turbine generator

Abstract

This paper studied the mathematical model and calculation of each component of small and medium-sized wind turbine generators to improve its stability and power generation efficiency. The optimal modal gain and maximum power tracking range are obtained based on the traditional torque curve method. A complete maximum power tracking control strategy is developed based on the optimal torque curve method to conduct in-depth study and improvement. Finally, the feasibility and superiority of maximum power tracking control is verified via simulation. The improved maximum power tracking control can effectively accelerate the maximum power tracking process, making better capture of wind energy by the generator.
