Development of a Control Unit for the Angle of Attack of a Vertically Axial Wind Turbine

Abstract

This article presents the possibility of increasing the efficiency of a vertical-axis wind generator through the introduction of an automatic control system for the angle of attack of the blades. The calculation of the optimal position of the wind turbine blades for the maximum generation of electrical energy is given, and a developed scheme for controlling the blades using the sensors of the angular speed of rotation of the wind wheel by the anemometer and the current position of the blades is presented. The automatic control system implies the use of a PD controller. A comparison is made of two laboratory experimental models of vertical-axis wind turbines with and without the developed control system. This article focuses on optimizing the angle of attack and developing an automatic control system for vertical-axis wind turbines to increase their efficiency in generating electrical energy.

A Dynamic Control Model of the Blades Position for the Vertical-Axis Wind Generator by a Program Method

“…Combined, wind and solar energy provided a record fifth of the EUs electricity (22.3%)-a contribution larger for the first time than either nuclear (21.9%) or gas (19.9%) generation [6]. According to the Union of the Electricity Industry, Eurelectric, two-thirds of the electricity generated in Europe in the first half of 2023 is carbon-free [7]. The share of renewable energy sources is 40% of the total production, while electricity generation based on fossil fuels has fallen by 18% [8].…”

“…A review of the vertical-axis wind generator configurations can be found in [69], where the main problems of the available technologies are highlighted. As concerns the active control of wind generator performance by shaping the blades of the turbine, it starts from accurate simulations [70], which allows for strategies based on intelligent control aimed at fixing specific angles of attack [71] or blade pitching [72].…”
