Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment for obtaining, belongs to protection domain of the present utility model.
The utility model embodiment is described in further detail below in conjunction with accompanying drawing, is as shown in Figure 1 this practicality
New embodiment provides the front view of vertical axis aerogenerator closed-loop control system, is illustrated in figure 2 the vertical view of the system
Figure, with reference to Fig. 1 and 2, the control system includes executing agency, air velocity transducer, speed probe and feedback device, Fig. 1, figure
The part included in 2 is：Lun Grains 1, support bar 2, blade 3, anemobiagraph 4, rotational speed meters 5, servomotor 6, rotating mechanism 7, synchronization
Rotating disk 8, the first crank 9, connecting rod 10, the second crank 11 and corner tester 12, wherein：
The executing agency includes：Servomotor 6, rotating mechanism 7, synchronous rotating disk 8, the first crank 9, connecting rod 10 and second
Crank 11；
The air velocity transducer includes anemobiagraph 4；
The speed probe includes rotational speed meters 5；
The feedback device includes corner tester 12.
The annexation and the course of work of each part be：
The executing agency receives the control parameter that wind-driven generator is determined by design requirement, and is opened according to the control parameter
Dynamic wind-driven generator；
The air velocity transducer detects the actual wind speed at the wind-driven generator operation scene, and the actual wind that will be detected
Fast signal transmission is to executing agency；
The executing agency adjusts the blade angle of the wind-driven generator according to the actual wind speed for detecting, by described anti-
Whether the angle of feedback device detection blade reaches the angle of requirement, and whether the rotating speed detected through the speed probe is advising
The fixed range of speeds, to ensure the stable operation of the wind-driven generator.
In implementing, the executing agency adjusts the blade angle of the wind-driven generator according to the actual wind speed for detecting
The process of degree is specially：
1) when detecting actual wind speed and reaching default threshold wind velocity, the air velocity transducer sends instruction by Lun Grains
In executing agency-electric turntable the blade of the wind-driven generator is rotated to the low wind speed of default using crank connecting link
Start the angle of attack, blower fan starts a cut through operation；
Blade can be gone to a low wind speed and start the angle of attack by the operation in low wind speeds, blade is produced revolving force away from general
Wind wheel is rotated, so as to reduce incision wind speed.
2) when detecting actual wind speed and reaching rated wind speed, the air velocity transducer sends instruction will by executing agency
Blade goes to the angle of attack that can produce stabilized (steady-state) speed of default, and the rotating speed detected by the speed probe is by performing structure
The rotating speed of blower fan is controlled to be operated in the range of speeds of regulation, blower fan (i.e. wind-driven generator) enters full hair-like state；
The operation can make blade realize maximum pneumatic efficiency, more effectively using wind resource.
3) when detecting actual wind speed and reaching cut-out wind speed, the air velocity transducer is sent instruction and is adjusted by executing agency
Completeblade angle reaches maximum resistance angle, produces resistance, wheel speed is declined last stopping, and blower fan cuts out operation；
4) stopped operating when speed probe detects the wind-driven generator, the feedback device sends instruction by holding
It is locked that row mechanism fixes blade angle, to ensure that the wind-driven generator will not be rotated.
Accordingly even when reach capacity wind speed when, it is also possible to the angle of blade is gone into maximum resistance angle, wind wheel forms sky
Gas is braked, so that it is guaranteed that the safety of wind-driven generator.
In addition, when live wind speed increases, speed probe and air velocity transducer can all send signal, and the control system will
Preferential collection precision signal high sends instruction and changes blade angle, makes blower fan excellent all the time with pneumatic control stabilization wind speed round
Matter efficiently generates electricity at full capacity.
In sum, the control system that the utility model embodiment is provided can solve the problem that blower fan threshold wind velocity is high, wind wheel
The fluctuation of speed is big, the unstable, blower fan that generates electricity cannot normally cut out operation, can not ensure security problems in Limit of Wind Speed, from
And the generating for making wind-driven generator stabilization safety under various wind regime that can be full-automatic, high-quality and efficient.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
