Description
Technical field
The relevant a kind of wind energy generating plant of the present invention particularly relates to a kind of floating type wind energy receiving device that utilizes high altitude stream acting generating.
Background technique
Wind energy receiving device is the device of rotating mechanical energy exactly with wind energy transformation.Wind energy receiving device commonly used at present is a fan blade, is contained in the wind top of tower and drives generator for electricity generation.The restriction of wind-engaging tower height degree, this wind energy receiving device can only receive near utilize ground wind energy, and because the wind speed on ground is lower; Energy is less, if want to improve the power of wind-power electricity generation, can only adopt large-sized leaf blade as far as possible; Improve blowing area, this also brings the sharp increase of cost, and the fan blade size is because the restriction of material, technology and wind tower height degree; Can not unconfinedly increase, thereby restricted the further raising of generating capacity.
And well-known, its wind speed of the more past eminence of aerial air-flow is high more, and entrained energy is big more.Like the wind speed in 1000 meters high-altitudes are three times of ground, and then entrained energy is that (according to the wind energy density formula is P=1/2 ρ V near the ground 27 times
3).This shows that if can effectively utilize the high velocity air in high-altitude, with the wind energy receiving device of same kind, same sectional area, generating capacity can improve several times.Therefore, making full use of aerial flowed energy, to carry out wind-power electricity generation be to improve generating capacity, reduces the effective way of cost of electricity-generating.
For this reason, countries in the world have been developed the wind energy receiving device that utilizes the high altitude stream acting in succession at present.Wherein a kind of is Italian high casement kite power generation technology; Its working principle is: as the wind energy receiver, through pulling controlling rope (computer is accomplished automatically), make up against the wind kite distortion with large-scale paraglider (just said kite); Thereby reduction windage; The descending kite of leading side wind is then opened entirely, full blast resistance downwind, both sides windage difference forms the power of mechanism's unitary rotation.After wind energy transformation is mechanical energy, through wire rope the energy that receives is delivered to the ground runner, by runner energy is sent into generator, accomplish the purpose of generating.
This wind energy receiving device is owing to utilize the high speed wind energy in high-altitude, and single-machine capacity can reach gigawatt, and in addition, motor and power transmission and transformation system have improved Security all on ground.Compare with conventional wind generating technology, its construction cost is also relatively low.But its shortcoming is also apparent in view:
1, need complicated steering control system, the increasingly automated control of this Technology Need computer, and accurate wind finding device to be arranged on every side; Because kite is operated in the continuous change, does not have stable state (not only can not work under the stable state, and kite meeting falling down); The stress that needs continuous detection computations kite, the attitude of adjustment kite is so that make the kite of a side be in full blast resistance state; The running of pulling power generating equipment, the opposite side kite is in low windage state, to reduce resistance torque; Be power generating equipment can be all the time rotary electrification in one direction, therefore need complicated calculating control system.This technical stability is very poor simultaneously.
2, as previously mentioned; Kite need constantly switch under full resistance and lower resistance state could drive the power generating equipment rotary electrification; But along with the folding and unfolding of kite, can pulsatile impact constantly occur, the electricity that causes sending is pulsed; Correspondingly increased the investment of power transmission and transformation system, and the complexity of working procedure.
3, the energy density of wind-force is original just very low, also wants consumption of power to draw kiteflying, has further reduced wind energy utilization.
4, aeroelasticity is very poor, almost completely is resistance type, and efficient is low.
5, complicated operation, poor practicability: go up the long rope of km and haul the big kite in field pitch, let the lift-off complicated operation fly away.And 12 kites of whole system, just might twine together fully in the process of putting.In case wind is too little, kite might lose lift and can fall down.
In addition; Adopt high-altitude turbogenerator type, the high-altitude floating type wind energy electricity generating devices such as wheel type and high-altitude helicopter type that go for a drive in addition; The common feature of these devices is that wind energy receiving device and power facility are raised in the air by floating empty device together; Receive high altitude wind energy, and the power delivery that produces is gone back to ground.These electricity generating devices also all have some common shortcomings: 1, owing to wind energy receiving device and power facility are all floated sky be arranged in the air, cause the complex structure of wind electricity generating system, weight big, restricted the further raising of its power; 2, the electricity generating device that volume, weight are all bigger all is arranged in the air, in case crash, will constitute a threat to ground safety, and Security is relatively poor; 3, wind direction there is requirement; Be that the wind energy that receives of the wind of some direction is higher, the wind energy that the wind of other directions is received is lower, and the high altitude stream polytrope has restricted its effectively utilizing 4, need install floating empty device in addition additional wind energy; So that electricity generating device is risen up into the high-altitude, increased manufacture cost.
In order to overcome the problems referred to above; In application number 200910158160.8 Chinese invention patents that the applicant submits to, a kind of floating type wind energy receiving device is provided, it adopts the floating empty work of the spiral air bag with two helicoids; Receive the flowed energy of aerial all directions; And the rotation function of air bag is transferred to the power generating equipment generating acting on ground, and it is simple in structure, safe in utilization, easy to operate, and cost is also lower.This kind wind energy receiving device is owing to be to twine two helical surface that form each other by a column air bag tractive or two column air bags; And utilize many longitudinal traction ropes of helical surface setting to transmit power earthward; Therefore the size of its transmission torque depends on the pulling force and the spirochetal diameter of tow rope; And the diameter of wind energy receiving device need add the size of air vesicle accordingly if do greatlyyer, and the possibility of result that therefore increases transmission torque causes the cost of wind energy receiving device to increase; Thereby this wind energy receiving device relatively is fit to the higher occasion of wind speed usually to be used.
