FIELD: power industry.
SUBSTANCE: invention relates to power engineering, to wind power plants. The adjusting device for adjustment of angle of mounting of rotor blades of wind power plants contains a servomotor for movement of rotor blades to change the angle of mounting, the control unit for servomotor control by means of electric current. The control unit is connected to the power supply mains. The emergency power supply device for servomotor power supply and control is used in case of failure of power supply mains. The emergency power supply device has an electric battery for accumulation of electric energy for powering the servomotor control. The control unit is intended for charging with electric energy of the electric battery of the emergency power supply device.
EFFECT: simplification of regulation and improvement of reliability.
