Description

Damping device of wind driven generator

Technical Field

The utility model relates to a wind power generation equipment technical field, in particular to aerogenerator's damping device.

Background

The wind power generator is an electric power device which converts wind energy into mechanical work, and the mechanical work drives a rotor to rotate so as to finally output alternating current. The wind-driven generator generally comprises wind wheels, a generator (including a device), a direction regulator (empennage), a tower, a speed-limiting safety mechanism, an energy storage device and other components. The wind driven generator has simple working principle, the wind wheel rotates under the action of wind force, the kinetic energy of the wind is converted into mechanical energy of a wind wheel shaft, and the generator rotates under the drive of the wind wheel shaft to generate electricity.

The existing wind driven generator is easy to be subjected to lateral wind force during operation due to the high installation position, so that the wind driven generator generates vibration. In the past, the operation of the wind driven generator is abnormal, the normal working performance of the generator is influenced, and meanwhile potential safety hazards are brought.
