Abstract. The article presents the general concept of developing a system for automatically lowering the rotor of a wind turbine to protect against strong wind loads. Modern research in the field of automation and optimization of wind turbines shows significant progress. The article provides an overview of the work of a number of scientists on the importance and implementation of adaptive and predictive control methods to improve turbine efficiency and stability. These achievements emphasize the importance of introducing advanced technologies to improve the efficiency and reliability of wind turbines, despite the fact that significant theoretical and practical efforts are required to implement them. Various components were also investigated and analyzed for the development of a linear actuator control system for unloading wind turbines under heavy wind loads. The main focus is on describing the key components of the system, such as an anemometer, a PID controller, a frequency converter, and a linear actuator, as well as their interaction within a mathematical model. The scheme of an automatic control system using a PID controller to lower the rotor of a wind turbine in high wind conditions is analyzed. To bring the control system to optimal parameters, the critical value of the wind speed is calculated using the energy method. The calculation of the critical wind speed is given, at which the protection system is activated. Combining all components of the control system into a single closed-loop control system ensures stable and reliable operation of the wind turbine, reduces the risk of damage and optimizes performance. The proposed concept serves as the basis for further research and development of full-fledged solutions aimed at improving the reliability and efficiency of wind turbines.
