Abstract
This paper presents an analysis of the dynamics of the wind systems that work at variable wind speeds. This analysis is based on numerical simulations that use the motion equation. In this paper, usual mathematical models of both wind turbine and permanent magnet synchronous generator are used. Based on the measurements of both wind speed and generator speed, two basic sizes are defined, namely the equivalent wind speed and the optimum mechanical angular speed. The optimum mechanical angular speed is a function of equivalent wind speed. By analyzing the time variation of the generator rotation speed, the area of optimum functioning can be determined and it is characterized by optimum mechanical angular speed.
