LOAD DISTRIBUTION ON THE WIND TURBINE ROTOR’S ROTATION STABILIZATION CHANNELS, CONTROLLED BY CHANGES IN ITS CONFIGURATION AND GENERATOR BRAKING TORQUE

Abstract

The paper considers the functioning of the Darrieus rotor rotation stabilization system of a vertical-axis wind turbine, controlled by simultaneous changes in the length of the blades, traverses, and the braking torque of a permanent magnet synchronous generator. In such a stabilization system, significant changes in the traverse length lead to changes in the rotor moment of inertia, which turns it into a non-stationary one and significantly complicates the synthesis of workable stable algorithms for forming feedback loops. To reduce this, it is proposed to use load distribution algorithms for the channels of changes in the length of the blades and traverses. It is proven that the use of the proposed algorithms significantly improves the dynamics of the stabilization system - it allows to significantly reduce the deviation of the length of the rotor traverses from their nominal values. The methods of solving the problem are mathematical modeling methods. The novelty of the results obtained lies in the extension of the method of load distribution of stabilization channels to a system with an additional control channel for changes in the generator braking torque.
