The Rotor Speed Controlling Possibilities of a Promising Wind-Driven Power Plant Using Several Variable Elements of Its Geometry

The stabilization of the rotor speed of a promising vertically axial wind-driven power plant is considered. It is proposed to use the aerodynamic method of stabilizing the rotor rotation angular speed by controlling the positions of two variable structural elements of the installation in the question relative to its stator. The controller synthesis technique by the rotor rotation angular speed is considered. A controller feature is the presence of two control channels with one state variable. Based on the second-order control error equation, the desired control law of the angular rotor speed is obtained. The synthesized control system was simulated with various input data. It is shown that the constructed controller is able to effectively counter the influence of wind disturbances in a wide range of deviations of the current speed from the desired frequency for a given target value.
