On the Dynamics of Small Wind Power Generators

Resumo

Based on the previously developed closed mathematical model, the dynamics of a small horizontal axis wind turbine are studied. The procedure for identifying the aerodynamic torque is proposed for the case when the electromechanical interaction is nonlinear in a current. Elements of the system for the comparative analysis of different wind turbines are developed. The results of simulating the behavior of the device are compared with the available experimental data. It is shown that good agreement takes place. The behavior of the system under a changing wind is studied.
