Description
Technical field
The present invention relates to the Oversea wind power generation technical field, especially a kind of whole driftage formula floating marine wind energy turbine set.
Background technique
The sea turn resource is very abundant, and along with the fast development of wind-powered electricity generation industry, the development and use of wind-resources turn to the ocean by land gradually.Wind energy content is about 7.5 hundred million kilowatts on the China sea, is equivalent to 3 times of land wind-powered electricity generation reserves.The offshore wind turbine foundation pattern has gravity fixed, post fixing type and the formula basis of floating usually, and what install on the basis at present still is conventional wind power generating set.
In order to make wind wheel obtain maximum wind energy, wind power generating set need use yaw system to keep wind wheel to be in state down with the wind all the time, yaw system is installed between cabin underframe and the tower tube top usually, use large diameter pivoting support and deviation drive device to make the cabin rotation, for the wind direction of avoiding vibrating changes, cause that the driftage gear teeth produce alternate load, also to or claim yawdamper to absorb small free deflection vibration with off-course brake, prevent that the alternating stress of yaw gear from causing that the gear teeth damage too early.This yaw system complex structure, poor reliability is safeguarded inconvenient.According to statistics, in all faults of wind-powered electricity generation unit, nearly 20% is to be caused by the driftage damage of bearings as pivoting support.If this fault occurs in marine wind electric field, will bring great trouble to user and the guardian of generator set.
