Wind Turbine’s Aerodynamic Multiplication Parameters for Different Types of Generators

Energy transition is impossible without wind power development. The need for a mechanical multiplier to match the speeds of a wind turbine and generator leads to deterioration of the tech-nical system's indicators. Refusal of a mechanical multiplier is possible with the help of aerody-namic multiplication. Despite the presence of work in this direction, there is still no coverage of the influence of aerodynamic multiplication parameters on the choice of a generator. Main objectives of the study – analyze the requirements that a generator makes to wind turbine’s aero-dynamic multiplication parameters. How these objectives were achieved: construction of regression models for existing wind turbines describing the dependence of the rotor diameter and the angular velocity of the wind turbine on the power; optimization of secondary wind velocity by the power of the wind turbine; proof of maximum of the secondary wind does not depend on the fixing radius of the secondary wind turbine; obtaining the dependence of the fixing radius of the secondary wind turbine on the angular velocity of the generator. The most important results are the calculation of the upper power limit, at which the use of aerodynamic multiplication is appropriate; obtaining recommendations for the selection of the secondary wind turbine fixing radius for different types of generators. The significance of the obtained results is in the systematization of experience foundations for selection of aerodynamic multiplication parameters; the formation of tasks for the optimization of wind power plant parameters according to strength parameters and the development of special generators.
