Description
Technical field
The present invention relates to wind generating technology, more particularly to a kind of side for mitigating wind-driven generator wheel-box rippling
Method.
Background technology
Wind-driven generator is the capital equipment for converting wind energy into electric energy, and crucial machine of the gear-box as wind-driven generator
Tool system, its performance quality play vital effect to the normal operation of wind-driven generator.Due to wind power generating set work
Make varying load bad working environments, in high-altitude set up, maintenance difficult, this just to gear train assembly operation dynamic property and
Reliability proposes very high requirement.
The factors such as wind-driven generator is due to rationing the power supply, failure can cause the disorderly closedown of unit, and at this moment unit can be in sky
Turn state, positive negative direction alternate rotation often occurs under being acted on due to turbulent wind in wind wheel, due to gear train assembly have it is larger
Backlash, cause the fretting wear of box portion tooth that spot corrosion occurs, cause the damage of gearbox drive internal system structure, reduce tooth
Roller box service life.
The content of the invention
In order to solve the above problems, the present invention provides a kind of technical scheme, can mitigate wind power generating set idling conditions
Rippling caused by lower tooth roller box fretting wear.
The technical scheme is that：A kind of method for mitigating wind-driven generator wheel-box rippling, including following skill
Art measure：
- gear-box slow-speed shaft set brake, when compressor emergency shutdown, brake input, wind wheel is stopped operating；
- monitoring high speed rotating speed, when wind speed changes, wind wheel can rotate when wind wheel torque is more than brake torque, work as high speed shaft
Rotating speed increases to V2When, excision slow-speed shaft brake, make wind wheel continue to rotate；When wind speed reduces, high speed rotating speed is reduced to V1When,
Slow-speed shaft brake is put into, and stalls wind wheel；Wherein, V2＞ V1；
- when wind speed exceedes regulation wind speed, slow-speed shaft brake is not put into, blower fan is remained idle state.
Beneficial effects of the present invention：
1st, when high speed shaft rotating speed reaches certain value（V2）When excision brake, make wind wheel continue to dally, when wind speed reduce, rotating speed
Drop to certain value（V1）When input brake, it is ensured that direction of rotation of the wind wheel during rotation speed change be it is consistent, no
Positive and negative direction alternate rotation can occur, so as to avoid the flank of tooth from colliding, mitigate rippling.
2nd, by detecting input, the excision that high speed rotating speed is braked come intelligent control slow-speed shaft, height corresponding to excision brake
Fast rotating speed is higher than high speed rotating speed, i.e. V corresponding to input brake2＞ V1, brake gear frequent operation can be prevented；It can subtract
The abrasion of few slow-speed shaft brake itself.
3rd, the brake size installed on slow-speed shaft is smaller, only need to apply certain brake torque, easy to implement.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the control flow chart of the present invention.
Embodiment
The present invention can mitigate wind-driven generator wheel-box rippling, it realizes structure by a kind of intelligent braking method
As shown in figure 1, the wind-driven generator includes wind wheel 1, slow-speed shaft 2, gear-box 3, high speed shaft 4, generator 5.The spy of the present invention
Point, it is that low speed brake 6 is set on slow-speed shaft 2, rotating speed detector 7 is set on high speed shaft 4.By robot control system(RCS) to brake
6 working condition is controlled.
As shown in Fig. 2 intelligent braking workflow is as follows：
When compressor emergency shutdown, the brake input makes wind wheel stop operating.
When wind speed changes, wind wheel can start to rotate when wind wheel torque is more than brake torque, when high speed rotating speed increases to V2
When, release slow-speed shaft brake, make wind wheel continue to rotate；When wind speed reduces, high speed rotating speed is reduced to V1When, slow-speed shaft brake is thrown
Enter, stall wind wheel.
When wind speed exceedes regulation wind speed, slow-speed shaft brake is not put into, blower fan is remained idle state.
In above process:
When high speed shaft rotating speed reaches certain value（V2）When excision brake, make wind wheel continue to dally, when wind speed reduces, under rotating speed
Drop to certain value（V1）When input brake, it is ensured that direction of rotation of the wind wheel during rotation speed change be it is consistent, will not
Generation positive and negative direction alternate rotation, so as to avoid the flank of tooth from colliding, mitigate rippling.
By detecting input, the excision that high speed rotating speed is braked come intelligent control slow-speed shaft, high speed corresponding to excision brake
Rotating speed is higher than high speed rotating speed, i.e. V corresponding to input brake2＞ V1, brake gear frequent operation can be prevented, reduces low speed
The axle brake abrasion of itself.
The brake size installed on slow-speed shaft is smaller, only need to apply certain brake torque, easy to implement.
