FIELD: energy.
SUBSTANCE: rotation frequency and power limitation system of wind-driven unit comprises installed horizontally in bearing housing with shaft passed through rod one end of system of links connected with fixed on shaft to turn about axes perpendicular to shaft, blades, and other with a control element made in form of a screw with screwed on it and fixed from longitudinal movement of disk with a drive for rotation of first actuator control device other end of rod is connected to screw actuator via thrust bearing screw slipping control element and is mechanically connected to blade angle sensor, control device is equipped with a second actuating element installed between electric circuit and windings of generator and to corresponding inputs of control device connected to outputs of sensors: blade angle, wind velocity, rotation frequency, instantaneous values of current and voltage generator.
EFFECT: higher accuracy of limitation of power and frequency of rotation of wind-driven unit.
