SIMULATION OF DYNAMIC ALGORITHMS FOR LOAD DISTRIBUTION TO WIND TURBINE STABILIZATION CHANNELS

This paper considers the functioning of the rotor rotation stabilization system of a vertical-axis wind turbine (WTG) with a Darrieus rotor controlled by joint changes in the length of blades and traverses. In such a stabilization system, significant changes in the length of the traverses lead to changes in the rotor's moment of inertia, which significantly complicates the synthesis of workable stable feedback algorithms. To reduce this, it is proposed to use time-varying algorithms for redistributing the load to the stabilization channels. It is proved that the use of the proposed algorithms significantly improves the dynamics of the stabilization system, which allows to significantly reduce the changes in the deviations of the rotor traverse lengths from their nominal values. The methods used to solve the problem are those of the classical theory of automatic control and mathematical modeling. The novelty of the obtained results lies in the extension of the concept of control by changing the swept area to vertical-axis wind turbines with a Darrieus rotor, which is controlled by joint changes in the length of blades and traverses.
