【 摘 要 】

The present paper analyses two control methods for wind power systems to achieve optimum performance in terms of energy. The load control methods at wind turbines (WT) to achieve optimal operation, is based on the fact that the energy captured by the wind energy depends significantly on the mechanical angular velocity (MAV). In order to perform a function in the maximum power point (MPP) area, the load on the electric generator (EG) is changed and the power given by the wind turbine estimated. The first method, known as the small perturbation method, is widely used, becoming classic. The second original method consists in determining the optimal angular mechanical velocity ω OPTIM, using a low power auxiliary wind turbine that operates without load, at maximum mechanical angular velocity ω MAX. This value of MAV takes into account the wind speed evolution in time. The method bases on the particularity of the ω OPTIM/ω MAX report that does not depend on the time variation of wind speed values and has a constant value for a given WT.
