Description
Technical field
The present invention relates to technical field of wind power generating equipment, in particular to a kind of wind power generating set system.
Background technique
Wind energy is as a kind of clean renewable energy, the increasingly attention by countries in the world.Its amount of accumulateing is huge, the whole world
Wind energy be about 2.74 × 109MW, wherein available wind energy is 2 × 107MW, than the water energy total amount that can be developed and used on the earth
Also want 10 times big.Fan yaw system is the distinctive control system of wind power generating set, and the yaw system of wind energy conversion system is also referred to as pair
Wind apparatus, its role is to can quick smoothly be directed at wind direction when the direction change of wind vector, so that wind wheel obtains most
Big wind energy.Yaw control system is mainly by yaw measurement, yaw driving running part, knob cable protection device three parts group
At.Mainly realize two functions: first is that cabin tracking is made to change stable wind direction；Second is that the effect due to yaw causes in cabin
Portion's cable occurs winding and automatically terminates winding.Since wind energy has the characteristics that low energy density, randomness and unstability, because
The yaw bearing of this yaw system will bear shock loading caused by not specific wind-force, have discontinuous operation, and start and stop are frequent, pass
Torque delivery is larger, the high feature of transmission ratio.
Wind turbine control system is an amount Nonlinear Uncertain Systems complicated and changeable, when external environmental factor not
When determining, when as too big such as wind speed, inappropriate yaw angle can reduce the service life of blade or even entire unit, will cause larger
Influence, therefore, in time to yaw carry out diagnosis be the key that unit safety efficient operation.Traditional detection means is to rely on instrument
Device detection, with the raising that wind power plant lean operation requires, to the inline diagnosis of yaw system and grinding for correction yaw system
Study carefully and is increasingly becoming research hotspot.How in real time effective diagnosis and adjustment yaw system, can take into account wind-driven generator
The problems such as group service life and safe operation and wind energy utilization.
Summary of the invention

Position device；The support frame of the generating set and the yaw bearing inner ring are engaged by clamping by the positioner；It is described inclined
Avionics machine is fixed in the pylon；The lateral instrument of wind speed and the unit position detecting device distinguish the yaw control
Device electrical connection processed；The yawer is electrically connected with the yaw motor；The worm screw and the yaw motor are rotatablely connected；
The yaw bearing includes drive mechanism, and the worm screw engages with the drive mechanism.
Based on the above technical solution, the present invention can also be improved as follows.
Optionally, the yaw motor includes: asynchronous machine or servo motor.
Optionally, the yaw motor is at least arranged three, and each yaw motor is sequentially connected a worm screw respectively.
Optionally, the drive mechanism is envelope turbine；The worm screw is enveloping worm.
Optionally, the outer rim of the positioner is equipped with arc groove corresponding with the land, which has upper and lower
Wall surface and side wall surface, lower wall surface are equipped with the friction plate with land frictional fit, and the curved side wall surface of the positioner is same
On one circumference, the radially limit cooperation of the corresponding side surface of the curved side wall surface and land.
The beneficial effects of the present invention are: detecting wind direction and generating set by wind speed direction finder and unit position detecting device
Position, whether be sent to data processor for analysis generating set to wind, and generate control instruction pass through yawer control
Yaw motor and positioner realize generating set to wind, and after finally to wind.
