Active power regulation in wind turbines

Purpose. To develop a methodology and determine rational parameters of wind energy installations with doubly fed induction generator to ensure maximum efficiency, taking into account changes in wind flow speed and power regulation to maintain stable and efficient operation of the installation. Methodology. This study used a combination of theoretical analysis and mathematical modeling. Analytical models for estimating wind turbine power were developed through regression analysis, incorporating key parameters such as wind speed, blade pitch angle, and the generator’s synchronous rotation speed. Findings. Parameters and conditions ensuring maximum power of a wind turbine with a doubly fed induction generator were established and analyzed. It was determined that the efficiency of the wind turbine installation with a doubly fed induction generator depends on the nature of the wind flow. Active power regulation allows for an increase or stabilization of output power with changes in wind speed. The established dependencies allowed for determining the optimal conditions for ensuring maximum power. Mathematical modeling confirmed the theoretical conclusion regarding the increase in electricity generation efficiency with the rational selection of the specified parameters of the wind turbine. Originality. The influence of key wind turbine parameters on the conditions for realizing the maximum power mode as well as the possibilities of using the speed regulation range of the wind turbine to limit excessive mechanical loads during wind gusts were determined. The study enhances the understanding of how synchronous torque affects the stability of wind generator operations, emphasizing the need for its control to maximize output power under various wind load levels. Practical value. The established dependencies between key parameters of the wind turbine and their impact on operational efficiency allow for more allow for more precise tuning of wind turbines to achieve maximum productivity during wind gusts. This is crucial during the design and operational phases. The developed methodology for regulating the rotor speed can help reduce operational costs by ensuring stable operation of wind turbines over a wide range of wind speed. The data obtained may also facilitate the development of control systems that automatically adapt wind turbine parameters to changing conditions. This will contribute to increased efficiency of wind energy use and reduced impact of wind turbines on the stability of the power grid.
