WIND-DRIVEN UNIT WITH POWER LIMITATION SYSTEM AND ROTATION FREQUENCY Russian patent published in 2016 - IPC F03D1/06 F03D7/04 

FIELD: energy.

SUBSTANCE: invention relates to wind power engineering. Wind-driven unit with power limitation system and rotation frequency, in which rod is passed via a shaft with possibility of movement in axial direction, connection rod with blades is performed through the system of links, the opposite end of the rod has a thread with screwed conical gear fitted on the shaft end to turn about its axial line and connected via gearing with drive gear fitted on mounted on the shaft axis perpendicular to axial line of the shaft, on the same axis fitted rigidly and coupled with drive gear friction disk, forming a pair of friction engagement with two located on both sides in vertical axial line shaft planes brake rings secured coaxially with the shaft on bearing housing with possibility of axial displacement in direction of the friction disk under the action of actuators of automatic control system, the input of control device is supplied with signals from two limit switches recording the extreme position of rod in axial direction.

EFFECT: higher accuracy of control of power and rotation frequency of wind-driven unit generator.
