Description
Technical field
The utility model belongs to electricity generating device technical field, particularly wind electricity generating system.
Background technique
The energy is the basis of economic development, in order to keep rapid development of economy, and predatory recovery of subterranean resources, its price is doubled and redoubled along with being becoming tight earth resource day.People are seeking alternative energy source in order to solve energy crisis, and wind energy has obtained the great attention of countries in the world as a kind of alternative energy source.In recent years along with the formation and the scale development of wind-powered electricity generation industry, by introducing technology, add speed wind-power unit localization process and strengthen wind energy turbine set construction and operation management, the cost of China's wind energy turbine set construction and operation progressively reduces, and initial outlay is reduced to present about 9000 yuan/kW from about 12000 yuan/kW in 1994.The rate for incorporation into the power network of wind-powered electricity generation also is reduced to about 0.6 yuan/degree from surpassing 1.0 yuan/degree simultaneously.
Wind-power electricity generation has three kinds of methods of operation: the one, and the independent operating mode, normally a small-sized wind power generator provides electric power to a family or a few family, and it uses the storage battery accumulation of energy, to guarantee the electricity consumption when calm; The 2nd, wind-power electricity generation combines with other generation modes (as diesel power generation), to a unit or a village or an island power supply; The 3rd, wind-power electricity generation is incorporated conventional operation of power networks into, provides electric power to big electrical network, usually is that place's wind energy turbine set is installed tens even hundreds of typhoon power generator, and this is the main developing direction of wind-power electricity generation.
Two critical pieces are wind energy conversion system and generator in wind-power generating system.Wind energy conversion system towards become slurry apart from regulation technology, generator towards the variable speed constant frequency generator technology, this is the trend of wind generating technology development, also is the core technology of current wind-power electricity generation.The wind energy conversion system main structure is divided into:
1, the change of wind energy conversion system slurry is apart from regulating
Wind energy conversion system is converted to wind energy the machine torque that acts on the wheel hub by the impeller capturing wind energy.The displacement regulative mode is the angle by change blade windward side and longitudinal rotating shaft, thereby influences the stressed and resistance of blade, and the increase of blower fan output power during the restriction strong wind keeps output power constant.Adopt the displacement regulative mode, the power of fan curve of output is level and smooth.When rated wind speed was following, controller placed attack angle of blade near the zero degree, does not do variation, was similar to be equal to fixed slurry apart from regulating.When rated wind speed is above, become slurry and have an effect apart from control structure, the adjusting vane angle of attack is controlled at output power near the rating value.It is low apart from wind energy conversion system apart from the fixed slurry of the priming speed of wind energy conversion system to become slurry, transmits impact stress during shutdown and relaxes relatively.During proper functioning, mainly be to adopt power control, in actual applications, cube being directly proportional of power and wind speed.Less wind speed variation can cause wind energy greatly to change.
Because it is much smaller than other wind energy conversion system apart from the impact that the adjusting wind energy conversion system is subjected to become slurry, can reduce the material utilization rate, reduces overall weight.And displacement adjustment type wind energy conversion system can make blade keep the good angle of attack when hanging down wind speed, than stall-adjusted type wind energy conversion system better energy output is arranged, and therefore relatively is suitable for the lower area of mean wind velocity and installs.
The another one advantage that displacement is regulated is, when wind speed reached certain value, the Stall Type wind energy conversion system must be shut down, and displacement type wind energy conversion system can progressively change to the non-loaded extreme span on-mode of a blade position, avoids shutting down, and increases the wind energy conversion system generated energy.
The shortcoming that displacement is regulated is that gust response is required sensitivity.Stall-adjusted type blower fan is because the power pulsations that the vibration of wind causes is smaller, displacement adjustment type wind energy conversion system is then bigger, especially for the constant speed wind-driven generator that adopts the displacement mode, this situation is more obvious, the displacement system that does not require blower fan like this wants enough fast to the speed of response of fitful wind, just can alleviate this phenomenon.
2, speed-variable frequency-constant wind-driven generator
The AC excitation double-fed generator of the normal employing of speed-variable frequency-constant wind-driven generator, its similar wound type induction motor, just be added with slip ring and brush on the rotor winding, so, the rotating speed of rotor is relevant with the frequency of excitation, thereby, make the internal electromagnetic relation of double-fed generator not only be different from induction generator but also be different from synchronous generator, but it has some characteristic of asynchronous machine and synchronizer.
AC excitation double-fed speed-variable frequency-constant wind-driven generator not only can be realized variable speed constant frequency by amplitude, phase place, the frequency of control AC excitation, can also realize gaining merit, Reactive Power Control, can also play reactive-load compensation to electrical network.
There is following advantage in AC excitation variable speed constant frequency double-fed generator system:
1, allows prime mover variable-speed operation within the specific limits, simplified regulating device, the mechanical stress when having reduced speed governing.Make unit control more flexibly, conveniently simultaneously, improved unit operation efficient.
2, needing the power of VFC only is the part of motor rated capacity, and the converter plant volume is reduced, and cost reduces, and investment reduces.
3, regulate field current amplitude, the wattless power that can regulate is sent; Regulate the field current phase place, the active power that can regulate is sent.The application vector control can realize, the independent regulation of wattless power.
Vertical axis aerogenerator is a kind of structure (Φ type or be called Da Lie) of circular arc double-leaf, because its blowing area is little, it is higher to start wind speed accordingly, is greatly developed always, some trials are also several years ago being done by China, but effect is undesirable all the time.Because the design of H type vertical axis aerogenerator needs very a large amount of air hole Mechanics Calculation and digital simulation to calculate, adopt artificial method to calculate and once need the time in several years at least, and not just once to calculate to obtain correct result, so at computer also is not the very flourishing age, people can't finish this design concept at all.
Because the needs of particular application, China had begun this research in 2003, and constantly product is improved in the time in 2 years afterwards, at the beginning of 2005, product moves to maturity, and on the island and a large amount of wind-light complementary systems that to adopt with this novel vertical axis wind power generation machine be capital equipment in borderland.
The know-why of H type vertical axis aerogenerator:
This technology adopts air hole mechanics principle, and at the wind tunnel simulation of vertical shaft rotation, blade has been selected the wing shape of aircraft for use, and when wind wheel rotated, it can not be subjected to changing efficient etc. because of distortion; Its is formed with 4-5 blade of vertical line, fixes, connects the wind wheel that the connecting rod of blade is formed by the wheel hub of 4 dihedrals or 5 angular shape, is generated electricity by wind wheel drive rare earth permanent-magnetic generator and is sent to controller and controls the electric energy that the transmission ﹠ distribution load is used.
This know-why is according to the air strip theory, and the tangent plane that Practical Calculation can be chosen vertically-supplying air machine running shaft carries out computation model, presses the blade actual size, and the axis of rotation distance of each blade is a N rice; Simulate pneumatic coefficient calculations with the CFD technology, calculate principle and adopt the discrete digital method to find the solution the aerodynamic force of aerofoil section, with grid method the mobile Vorticity Distribution of reynolds' number is relatively formed under the high reynolds number Navier-Stokes equation is carried out digital simulation calculating principle result.
Adopt the principle of rare earth permanent-magnetic material generating, the wind wheel of supporting and air hole mechanics principle adopts the directly driving type structure to be rotated generating.
According to retrieval, a kind of wind-driven generator (patent No.: ZL200420081310.2) because this kind project organization has adopted special air hole mechanics principle, the Placement of triangle vector method and the principle of directly driving type structure, make the stressed of wind wheel mainly concentrate on the wheel hub, so wind loading rating is stronger; The characteristic of this kind design also is embodied in the influence to surrounding environment, and noise free and electromagnetic interference be little during running etc., and characteristics make that novel vertical axis wind power generation machine superiority is very obvious.
Along with the further developing of wind power technology, the vertical axis permanent magnet wind-driven generator was that the wind power technology industry is added the newcomer again, also progressively was familiar with by people in recent years.But no matter be horizontal axis or vertical axis aerogenerator, all fundamentally do not solve high this difficult problem of cost of investment, universal being subjected to of this clean energy resource limited in various degree.Trace it to its cause the metal stud cost ten of a typhoon power generator times over generator itself, be difficult to more to allow that the people accepts is that a metal stud can only carry a typhoon power generator group.

Embodiment
Shown in accompanying drawing 1-8, the suspended type vertical shaft wind power generator apparatus that the utility model provides comprises two series of modular suspended type vertical shaft wind power generator apparatus, in order to workout cost problem to greatest extent.Thereby this clean energy resource is popularized early.
Two groups of vertical shaft wind power generator apparatus by blade structure divide can be divided into vertical shaft fixedly the shape eddy current wing and vertical shaft from two kinds on the deformation level wing.Divide from the system sus-pension and can be divided into two kinds of classification sus-pension and concentrated sus-pension.
Fixedly the shape eddy current wing is as shown in Figure 1 for classification suspention vertical shaft:
It is made up of suspension hook (15), fixing suspention axle (1), hub bearing (7), hollow shaft permanent magnet generator (8), wheel hub and generator fixed support (9), classification shaft coupling piece (10), blade support (11), fan blade (12), hanging axis fixed tray (17).Fan blade is formed and equidistant intervals vertical vane (claiming the fan blade front) by the semicircle arcuation and by the identical partition in interval.Form eddy current down with the wind and in the fan blade front in the half cycle fan blade front of doing work down with the wind, blast is big.Fan blade is in non-acting half cycle (title transition zone), and this moment, the fan blade arc-shaped surface was facingd the wind, and distinguished and admirablely shunted from the blade perpendicular separation by the arc-shaped surface rectification.Blast is less relatively.Leeway drives the support rotation by fan blade.Supporting band runner hub (7) also passes through the stator rotary electrification that wheel hub fixed support (9) drives permanent magnet generator.Because generator adopts hollow shaft, fixedly hanging axis (1) passes the generator axle center and fixes with the armature of generator.The armature coil cutting magnetic line produces induction electromotive force, and its output is drawn and is connected to next stage by the suspention axis hole from a suspention axle center from armature coil.Because system adopts the mode that is layering, the output of generator can adopt series-parallel system to connect according to load request.
Fixedly the shape eddy current wing is as shown in Figure 2 to concentrate the suspention vertical shaft:
It is rotated hanging axis stationary hub (18), floor model permanent magnet generator (25), blade support (11), fan blade (12), is formed by suspension hook (15), rotation suspention shaft device (20), rotation hanging axis (19).Wind-force acts on the fan blade, and the leeway that is produced at work done half cycle and non-work done half cycle is by blade support (11) rotation hanging axis stationary hub (18) driven rotary hanging axis (19) rotation.Other fan blade that hangs of fixing produces the power acting in conjunction on the suspention axle on the rotation hanging axis simultaneously, makes the rotation of suspention axle drive the armature rotary electrification of floor model generator.
Vertical shaft also can be the classification sus-pension and concentrates the suspention dual mode from the deformation level wing.What the classification sus-pension was different with concentrated sus-pension is that the suspention axle does not rotate with the rotation of fan blade support, and employing hollow shaft permanent magnet generator, suspention axle pass from the generator axle center and with the armature relative fixed of generator, fan blade drives generator permanent-magnet pole stator rotary electrification by fan blade bearing wheel hub support.Because the generator unit stator magnetic pole adopts permanent-magnet material to make, number of magnetic poles can be determined according to mean speed, thereby overcome slow this defective of system's rotating speed.System adopts modularization to be layering, and the output of generator is drawn and passed fixing suspention axis hole from fixing armature coil and is connected with next stage from the hanging axis center.Can require to adopt flexibly series-parallel system output step by step according to output loading like this.
If wind speed high hundred meters up and down the wind-force difference be not that system can adopt concentrated sus-pension under the very big situation.This sus-pension characteristics: the one, suspention axle and the blade support structure that is fixed as one, therefore the suspention axle rotates with the driving of fan blade support; Second characteristic is: the fan blade automatic control system only needs can drive the adjustment of finishing the fan blade posture when all fan blades rotate in system once overlapping.The 3rd characteristics are: can adopt a high-power generator floor model to install centralized power generation.Specifically be that fan blade drives the armature rotary electrification that the suspention axle rotates and drive by universal joint the floor model high-power generator with wind-force.The advantage of this sus-pension is to have reduced suspention weight to greatest extent, maintains easily, and reduces system cost to greatest extent, can reach the effect of getting twice the result with half the effort.
Fixedly the shape eddy current wing its sus-pension of comparing is basic identical from the deformation level wing and vertical shaft for vertical shaft, but the difference of essence is arranged from blade structure and fan blade stressing conditions.When the deformation level wing rotates in the horizontal direction, regulate automatically in vertical direction the fan blade posture finish on work done half cycle blade face vertical, the fan blade work done of facining the wind; Fan blade is a level in non-work done half cycle fan blade stance adjustment, and fan blade is finished horizontal transition under very little resistance situation.From the blade structure of the deformation level wing as shown in Figure 4: there is a horizontal blade shaft that rotates with fan blade at horizontal tail cambered surface center, the fan blade windward side is adopted partition formula arc vortex structure equally, but compare with the fixing shape eddy current wing, horizontal tail adopts arc, fixedly shape employing semicircular arc structure.Horizontal tail horizontally rotates in order to make it.Adopted the work done of facining the wind of windward side half cycle, in addition half cycle fan blade posture adjustment horizontal transition.This process is to turn to the automatic posture adjustment of the fan blade system of shift fork (5) blade shaft steering link (6), fan blade interlock stay cord compositions such as (14) to finish by direction empennage (2), empennage rotating shaft (3), the automatic posture adjustment pallet of fan blade (4) blade shaft.Because it is to be similar to flat-topped cam and to be distributed in drum organization both sides, center by two its shapes of semi-circle isosceles trapezoid and effect that fan blade is adjusted pallet (4) automatically, and downward at fan blade work done half cycle flat-topped cam top, at all flat-topped cams of non-work done half cycle top upwards.Empennage rotating shaft (3) and center drum organization relative fixed, empennage rotating shaft (3) is two ends bearing and hanging axis relative fixed up and down, (concentrating suspention and classification to suspend in midair slightly variant) its effect is that empennage rotating shaft (3) does not exert an influence when each spinning mutually with hanging axis, guarantees its independence separately.Empennage (2) and support thereof and empennage rotating shaft (3) are fixing.Empennage drives the automatic posture adjustment pallet of fan blade together with the empennage rotating shaft and be fixed on an orientation under the effect of wind-force.The fan blade axis crosses vertical support frame (in bearing is housed) near being fixed with blade driving connecting rod (6) with level 45 degree angles on the fan blade axis of vertical support frame one side as figure two (2) FD orientation, and be installed with fan blade interlock stay cord (14) at the connecting rod two ends and see figure two (1), these fan blades of shift fork (A, B) that are fixed with angle on fan blade axis top and are 90 degree are defined as initiatively fan blade temporarily.Because the automatic posture adjustment pallet of fan blade is fixed on an orientation under the effect of wind-force, when the rotation of fan blade and support thereof and by fan blade adjustment district during to the horizontal transition district, (when being rotated counterclockwise) right angle shift fork is subjected to the reaction force on flat-topped cam inclined-plane to make it be rotated counterclockwise 90 degree, (A forwards the B position to, B forwards the C position to) thus drive fan blade by vertically becoming level, finish horizontal posture adjustment and keep.Facing the wind during the work done district to vertical when fan blade rotates to by horizontal transition, the active force that the shift fork that fan blade shift fork reason B forwards the C position to is subjected to the overhead cam inclined-plane is dialled shift fork and is got back to original position, make fan blade become vertical by level and the work done of facining the wind.Blade driving connecting rod (6) top at same orientation angle is all by fan blade interlock stay cord (14) relative fixed on hanging axis, when the posture adjustment of active fan blade other with the orientation fan blade in company with posture adjustment.
Its rotation angle in order to prevent fan blade fan blade far-end generation axial twist when vertically facining the wind, can be installed the limit stoper of 90 degree angles during the fan blade posture adjustment on the support at fan blade two ends in 90 degree scopes.Can be operated in magnetic suspension state when the magnetic force permanent magnet pieces makes its rotation by force at the shift fork stress surface and the flat-top cam face installation opposite sex for the surface friction drag that reduces shift fork and cam face simultaneously.
Vertical sus-pension is applied widely, and anti-high wind is attacked around ability strong, particularly the comparatively concentrated mountain pass of wind-force
Chuan Dao can adopt that wire rope is horizontal to be drawn in the piling of the mountain top faced mutually, and equidistant vertical suspention can maximum saving cost.
