Specific embodiment
The feature and exemplary embodiment of various aspects of the invention is described more fully below.In following detailed description
In, many details are proposed, in order to provide complete understanding of the present invention.But to those skilled in the art
It will be apparent that the present invention can be implemented in the case where not needing some details in these details.Below to implementation
The description of example is used for the purpose of providing by showing example of the invention and better understanding of the invention.The present invention never limits
In any concrete configuration set forth below and algorithm, but cover under the premise of without departing from the spirit of the present invention element,
Any modification, replacement and the improvement of component and algorithm.In the the accompanying drawings and the following description, well known structure and skill is not shown
Art is unnecessary fuzzy to avoid causing the present invention.
The invention proposes a kind of wind generator system suitable for low wind speed, which passes through to the reasonable of power generation wind speed
The optimization of the specific aim of selection and wind energy transformation technical solution, realizes the wind-power electricity generation under low clearance, low wind speed condition, significantly
The addressing range of wind-power electricity generation is expanded, can further power generation and electricity consumption link to the maximum extent, and can send out with other new energy
Electric scheme organically combines, and improves the generation of electricity by new energy total amount on unit area.
Firstly, briefly explaining the fan part in wind generator system according to an embodiment of the present invention.
The selection of blower type
Blower can be divided into lift-type blower and resistance-type blower two major classes.Under the conditions of wind speed is lower, resistance-type is vertical
Axis blower has better self-starting and torque characteristics, preferably to be used under such working condition.Resistance force type vertical shaft wind machine has
A variety of blade constructions, such as Sa Woniusi (Savonius) type blade construction, Scroll-type blade construction, Senegal's type blade knot
Structure etc..Wherein, the power coefficient (CP) of the blower of Senegal's type blade construction is up to 0.3 (about this type leaf of Saab knob
Twice or so of the blower of chip architecture), and Senegal's type blade construction it is simple, it is light-weight, with material is few, manufacture and installation are difficult
Spend low, therefore wind generator system according to an embodiment of the present invention can choose the vertical shaft fan of Senegal's type blade construction
As fan part (it will be appreciated by persons skilled in the art that wind generator system according to an embodiment of the present invention can also be with
Select the blower of other blade constructions as fan part).
Fig. 5 is the structural schematic diagram of the blower of Senegal's type blade construction.As shown in figure 5, Senegal's type blade knot
The blower of structure includes three groups of semicircle fan blades and straight panel fan blade, wherein three groups of fan blades are uniformly distributed around axis.Blower diameter D=3 × semicircle
The diameter d=3 of fan blade × straight panel fan blade length, straight panel fan blade are located in the normal direction of semicircle fan blade opening, one end and semicircle
Fan blade opening flushes.
Through hydrodynamics numerical simulation it is found that when wind blows to the blower of Senegal's type blade construction from left side, just
To very high wind pressure is generated on the inside of the semicircle fan blade of wind direction, which is transferred to the machine that fan shaft is converted to fan blade rotation through blade
Tool energy.White space in the middle part of blower quickly flows out for the air-flow after acting provides good low pressure and negative pressure channel, this
It is that the power coefficient of the blower of Senegal's type blade construction is higher than the mechanism place of S type blower.
The arrangement of blower
Vertical shaft fan is usually vertical placement, and this mounting means is not necessarily to wind, but fan shaft is in cantilever position, by
Power is in poor shape, and this cantilever design also limits the increase of blower height, is unfavorable for that blower swept area is adjusted flexibly.
Fan part in wind generator system according to an embodiment of the present invention uses horizontal installation, and the rotation axis of blower and ground are flat
Row.The cantilever beam of vertical installation is become the simply supported beam that there is support at both ends by horizontal installation, and stress is significantly better than vertical
Formula installation, the selection such as size, material of axis difficulty substantially reduce.It is horizontal that the expansion for being also convenient for blower length is installed, it can basis
It needs to be adjusted flexibly the swept area of blower, realizes the design of different size installed capacity.In addition, when horizontal installation, identical bits
The blade set is in identical height, and received wind speed is also almost the same, and the torque of blower along its length is consistent, stress equalization；
And the received wind speed of blade institute of vertical installation changes and (closes between wind speed and height at power exponential function with height change
System), blower entirety stress is in imbalance, is unfavorable for the stabilization of wind generator system.
When the horizontal installation of blower, need to carry out to make character and conduct.Wind generator system according to an embodiment of the present invention is by blower
It is placed on the rotary type load bearing equipment that can be horizontally rotated, adjustable strategies is drafted according to wind-force information and driving motor is acted wind
Machine is adjusted to upwind position.Electric energy for driving rotary type load bearing equipment to rotate can be provided by outside.
The selection of height and wind speed range
Air is the sticking fluid of tool, and in the region close to boundary layer due to the influence of frictional force, air velocity can subtract
Slowly, can also because of barrier presence and generate turbulent flow.
Wind generator system according to an embodiment of the present invention generates electricity suitable for low wind speed range.Comprehensively consider wind-power electricity generation system
System is ensuring blower height to factors such as the applicability of the different geographicals such as field, city, transportation, installation, maintenance and cost control
Under the premise of air flow boundary layer height, blower is highly preferred in wind generator system according to an embodiment of the present invention
No more than 6 meters, and the total height of the wind generator system is preferably more than 10 meters.
Relationship between wind speed and wind power can be indicated with following formula:
Wherein, p is wind power；V is wind speed；S is the area perpendicular to wind direction；ρ is atmospheric density.
Following table gives under different wind speed, the vertical shaft wind of 2.25 meters of diameter, long 7.2 meters of Senegal's type blade construction
The shaft power of machine.
1 wind speed of table and shaft power
| Wind speed m/s | 3 | 6 | 9.5 | 11.2 |
| Power W | 82 | 656 | 2604 | 4267 |
From table 1 it follows that the shaft power of blower output has had can benefit after wind speed reaches 6 meter per seconds (m/s)
With value.Simultaneously, it is contemplated that the availability of wind speed, selecting completely hair wind speed is 9.5m/s, i.e. effective use wind speed range is 6-
The geographic area of 9.5m/s, the wind speed range are extensive, be conducive to wind generator system according to an embodiment of the present invention addressing and
It promotes.
In the following, being described with reference to the accompanying drawings wind generator system according to an embodiment of the present invention.
It is between the diameter and revolving speed of blower inversely, proportional between torque under given wind speed.It is identical
Under wind speed, for different blower diameters, blower can take straight drive mode according to the height of revolving speed, to the mode that turns and speedup
Any one in mode is connect with the generator in wind generator system.
When blower takes straight drive mode to connect with generator, the torque of blower can not be direct by gear-box speedup
It is transmitted to the shaft of generator, the shaft of generator drives rotor rotation and cutting magnetic line produces electricl energy.Blower takes straight drive
The structure for the wind generator system that mode is connect with generator is the most succinct, reduces probability of failure, but is only suitable for using revolving speed
Higher blower.
When blower is used and is connect to the mode that turns with generator (generator is birotor generator at this time), birotor power generation
The two sides of machine are respectively arranged with a Fans, and the coil and exciting part of birotor generator are driven by the blower of its two sides respectively
It is dynamic, and the direction of rotation of this two Fans is on the contrary, form the effect of 2 times of speedups.It is taken in blower and the mode that turns and generator is connected
In the wind generator system connect, the speedup gearless driving link of blower, efficiency, life and reliability, which are higher than, uses speedup mode
The blower being connect with generator, but speedup limited extent, the slightly aobvious complexity of installation and debugging, and it is suitable for the wind medium using revolving speed
Machine.
When blower is connect using speedup mode with generator, the revolving speed of blower is improved by gear increaser, speed increasing ratio
Maximum, suitable for the blower using major diameter, the slow-speed of revolution.
Use is illustrated the embodiment for turning scheme and speedup scheme below.
Compact Layout is to turning scheme
