The possibilities of stabilizing the rotor speed of a vertical-axial wind power installation are considered, which can be included as an element in a complex power energy installation for additional and emergency power supply of surface robotic complexes. For this purpose, it is proposed to use the method of stabilizing the angular velocity by controlling the position of the moving structural element of the installation in question. Received the corresponding law of regulation of the angular velocity of rotation of the rotor. The equations of the system for stabilizing the rotor rotation frequency with aperiodic wind disturbance are simulated. It is shown that the constructed regulator is able to effectively counter the influence of wind disturbances. A regulator has been synthesized that allows the stabilization of the rotor speed of a wind turbine of a vortex type using variable elements of the wind turbine geometry. The regulator is able to maintain the value of the angular velocity of the rotor with wind disturbances with an amplitude of the aperiodic component of no more than 2.5 m / s with a transient duration of no more than 6 seconds. This is achieved with a significant dynamic range of control value. Using this method of regulating the speed of the rotor of the wind turbine will significantly improve the adaptability of the control system with respect to its output characteristics; significantly expand the dynamic range of torque control on the rotor of a wind power installation, as well as increase the robustness of these characteristics to external wind and internal structural parametric perturbations.
