Utilize the turbine electricity generation system of driving wind of train

Technical field

The present invention relates to a kind of turbine electricity generation system that utilizes driving wind of train.

Background technique

Along with China's expanding economy, coming into operation of large quantities of electric railways such as Beijing-Shanghai express railway indicates that the railway of China begins to enter the high ferro epoch.The development that the construction of railway is swift and violent, incident is that the electric energy that consumes on the railway auxiliary facility also gets more and more.The driving wind collecting generating that utilizes specially designed vertical axis windmill that bullet train is travelled and produces later.Show that according to the study train advances needing to overcome aerodynamical resistance in motion.The headstock of train can tie up the position of original air, air is pushed around vehicle body, and exist the space that is close to vacuum at last vehicle of train.Huge air density missionary society forms strong wind [seeing Li Li for details, the research of vehicle transient state air dynamic behaviour under the specific motion state, Shandong University, thesis for the doctorate] so that strong flowing occurs air.

Train wind the head of train and afterbody by the time the highest, and vehicle body by the time more steady.Show that according to the study be more than 0.5 meter the time at distance compartment outer wall apart from d, wind speed and the d of train wind are linear, slow decreasing.When train passed through with 200m/s, the wind speed at d=2 rice was about 11m/s.By wind-driven generator is installed at the safe distance place, can gather the train wind energy and generate electricity.The electric energy that sends is stored in the storage battery through over commutation, utilizes controller that the battery pack networking is integrated, and finally powers to electric power facility along the line.[see Zhang Xiaogang for details, Liu Yingqing, Zhao Haiheng, the unstable turbulence during bullet train process roadside buildings thing streams numerical simulation study, railway society, 19982002].Utilize the train wind energy power, the train wind that studies show that at present common bullet train is at distance train sidewall slow decreasing during apart from 0.5-3.5 rice, and wind speed is in the 18m/s-7m/s scope.Wherein the wind speed at 2.5 meters is about 9m/s.And train wind can produce strong turning effort power at headstock and the tailstock through out-of-date, [see Li Renxian for details, Zhao Jing, an administration, Peng Yuming, High-Speed Trains be near the startup function influence of human body, Chinese railway science, 1001-4632 (2007) 05-0098-07].Train is consuming huge energy simultaneously, the wind energy that train vibration influence produces is but ignored by people always, according to document [Chinese Research Institute for Building Sciences, He Lianhua, Fu Longbiao, Chen Kai, Deng, " Wuhan Station High-Speed Trains numerical simulation study "], show, when train moved with 200km/h, the wind speed at 0.5 meter of distance train can reach 72km/h; This just means that the train travel wind speed reaches 12 grades.Consume aerial energy and remain huge.

Because train is way traffic at railway, the direction of train wind also is two-way, and this just needs wind-driven generator real-time tracking wind direction.In the hope of utilizing to greatest extent wind energy, the wind energy of train is liftoff nearer in addition, and wind speed is lower at ordinary times, easily causes the wind-driven generator difficulty in starting, and the other limited space of railway, and is very large to the diameter restrictions of horizontal axial type blower fan.The perpendicular axis type blower fan then possesses the characteristics that satisfy above-mentioned condition.Yet the wind wheel of each pattern of perpendicular axis type has different performance, and merits and demerits is all arranged.Can not reach in actual applications the best applications effect.See following table 1

	H type wind wheel	φ type wind wheel	S type wind wheel
				The blade complexity	Simply	Complicated	Simply
Detent torque	Little	Little	Greatly
				The pneumatic shear effect	Little	Greatly	Little
Whether need vang	Can select	Be	No
				The aerodynamic noise size	Little	Medium	Little
Blade area	Greatly	Little	In
				Moment of flexure	Greatly	Little	Little

Table 1

In addition, after train crosses, because the driving disturbance is moving larger, cause wind power generator impeller and rotating speed that violent impact is arranged, not only cause the fluctuation of the magnitude of voltage of sending out, cause the damage of wind generator device when serious.Generally, often take simple and easy engaging and disengaging gear to disconnect being connected of impeller and generator, though this method avoids motor to damage because of hypervelocity, but the same fluctuation of output voltage is larger, simultaneously, wind power generator impeller since underloading often after running up working life greatly reduce, and then whole system is impacted.

What the present invention adopted is the scheme of S type wind wheel and the combination of H type wind wheel, wishes to realize having complementary advantages by two kinds of different wind wheels.But two kinds of wind wheels also can produce other problem when having complementary advantages: (1) determines that according to a conventional method the physical dimension of H wheel is not suitable because the S wheel exerts an influence to the aeroperformance that H takes turns; (2) be difficult for determining the physical dimension of S wheel is got when how to be worth actually, could both start smoothly whole wind wheel has the effect of aerodynamic performance of couple H wheel less [sees He Zongjing for details, the research of Darrieus-Savounius combination wind wheel aeroperformance, solar energy journal, 1992,13 (3): 239-244].Below we carry out designing and calculating according to the Proper Match condition of S wheel and H wheel and the aeroperformance requirement after the combination to the concrete physical dimension of combination wheel.

The physical dimension of S type wind wheel is calculated: S type wind wheel mainly is comprised of two semi-circular blades that central axis staggers mutually, with the wind and the blade that moving concave-blade and convex surface facing the wind forms the passage of workmanship air-flow, under the guiding of two blades, air-flow is transferred, the turnover air-flow produces and wind direction opposite effect power the blade that convex surface facings the wind, thereby has reduced the merit that this contrary wind blade consumes.The eccentric distance e of two semi-circular blades has determined the size in this inner air flow cross section, passageway.According to the study [see Wang Xin for details, Tong Zhengming, Wang Qikun, the numerical value research of guide-type vertical-axis wind turbine aeroperformance characteristic, Shanghai University of Science and Technology)] show: when e/d=1/6, the performance of wind wheel is best.Its power coefficient Cp is the highest, can reach 0.3.The optimum tip-speed ratio λ value is 0.9-1.The present invention need to determine height h and the curved surface diameter d of S type wind wheel.Make the S wheel start starting torque and rotational resistance distance that the H wheel need to overcome generator,

M _S≥M _C

(1) that is $\frac{1}{2}\·\mathrm{\ρ}\·S_S\·C_m\·{\mathrm{\υ}}^2=\mathrm{\μ}\·M_c$

And $r=d-\frac{1}{2}$

$e=\frac{1}{6}d$

(2) formula

In: ρ--come current density; V--starts wind speed; The detent torque coefficient of Cm--S wind wheel; , the tip radlus of r--S type wind wheel; The starting torque of MS--S type wind wheel; The starting torque of Me--generator and rotational resistance distance and; μ--reliability coefficient; The sweeping area of Ss--S type wind wheel.And

$S_s=h(2d-e)=\frac{11}{6}\mathrm{dh}=\mathrm{hD}---\left(3\right)$

(2) physical dimension of H type wind wheel: the physical dimension of H type wind wheel has: tip radlus R, height 2H and chord length C.After the height of tip radlus and wind wheel was determined, the sweeping area SD of H type wind wheel was tried to achieve by following relationship:

S _D＝i·HR (4)

Wherein: i=2.Extreme breadth on the wind sweeping area of wind wheel becomes blade diameter length ratio j with the ratio of height:

$j=\frac{H}{R}---\left(5\right)$

When the rated power of generator is P, then have

$p=\frac{1}{2}\&CenterDot;{\mathrm{\&rho;}}_o\&CenterDot;S_H\&CenterDot;{\mathrm{<figure-callout\; id="3"\; label="V\; o"\; filenames="HDA0000067976590000011.png"\; state="\{\{state\}\}">V</figure-callout>}}_o^{}\&CenterDot;{\mathrm{\&eta;}}_1\&CenterDot;{\mathrm{\&eta;}}_2\&CenterDot;C_P^{H+S}---\left(6\right)$

So

$S_H=\frac{2P}{{\mathrm{\&rho;}}_{\mathrm{<figure-callout\; id="3"\; label="o\; V\; o"\; filenames="HDA0000067976590000011.png"\; state="\{\{state\}\}">o</figure-callout>}}{V}_o^{}{}_3^{}\&CenterDot;{\mathrm{\&eta;}}_1\&CenterDot;{\mathrm{\&eta;}}_2}\&CenterDot;\frac{1}{C_P^{H+S}}---\left(7\right)$

In the formula: ρ 0---come current density; η 1---generator efficiency; η 2---transmission efficiency; CS+H---the power factor of combination wind wheel; The design wind speed of V0---wind wheel; The power factor of combination wind wheel can be got by document [19]:

$C_P^{H+S}=C_P^H-K_0(C_P^H-C_P^S)---\left(8\right)$

The condition that following formula is set up is:

$\frac{r}{R}=\frac{{\mathrm{\&lambda;}}_S}{{\mathrm{\&lambda;}}_H}---\left(9\right)$

In the formula: λ _H---the best tip-speed ratio of H type wind wheel; λ _S---the best tip-speed ratio of S type wind wheel;

---the best power coefficient of H type wind wheel;

---the best power coefficient of S type wind wheel; Wherein

$K_o=\frac{S_S}{S_H}---\left(10\right)$

Order

$K=\frac{2P}{{\mathrm{\&rho;}}_{\mathrm{<figure-callout\; id="3"\; label="o\; V\; o"\; filenames="HDA0000067976590000011.png"\; state="\{\{state\}\}">o</figure-callout>}}{V}_o^{}{}_3^{}\&CenterDot;{\mathrm{\&eta;}}_1\&CenterDot;{\mathrm{\&eta;}}_2}---\left(11\right)$

$N=\frac{2\mathrm{\&mu;}{M}_c}{\mathrm{\&rho;}{V}^2{C}_m}---\left(12\right)$

The above set of equation of simultaneous can get:

$R^3-\frac{K}{C_P^H\mathrm{ij}}R-\frac{{\mathrm{N\&lambda;}}_H}{C_P^H\mathrm{ij}{\mathrm{\&lambda;}}_S}(C_P^H-C_P^S)=0---\left(13\right)$

Can be rewritten as:

R ³+aR+b＝0 (14)

Wherein:

$\left\{\begin{array}{c}a=-\frac{K}{C_P^H\mathrm{ij}}\\ b=-\frac{N{\mathrm{\&lambda;}}_H}{C_P^S\mathrm{ij}{\mathrm{\&lambda;}}_S}(C_P^H-C_P^S)\end{array}\right.---\left(15\right)$

According to document [20] [seeing Desire LE Gourieres.Wind Power Plants.PergamonPress.1982 for details]

, have

${\mathrm{\&lambda;}}_H=\sqrt{\frac{5R}{\mathrm{nC}}}---\left(16\right)$

So chord length C is

$C=\frac{5R}{n{{\mathrm{\&lambda;}}_H}^2}---\left(17\right)$

In the formula, n is the number of blade of wind wheel.

The physical dimension of S type wind wheel is

$\left\{\begin{array}{c}d=\frac{12{\mathrm{\&lambda;}}_{\mathrm{<figure-callout\; id="11"\; label="S"\; filenames="HDA0000067976590000031.png"\; state="\{\{state\}\}">S</figure-callout>}}}{11{\mathrm{\&lambda;}}_D}\&CenterDot;R\\ h=\frac{N{\mathrm{\&lambda;}}_{\mathrm{<figure-callout\; id="2"\; label="D"\; filenames="HDA0000067976590000011.png"\; state="\{\{state\}\}">D</figure-callout>}}}{2{\mathrm{\&lambda;}}_s}\&CenterDot;\frac{1}{R}\end{array}\right.---\left(18\right)$

Require every physical dimension of blower fan is carried out designing and calculating according to wind speed.[see Wang Nianxian for details by document, Zhang Jin's light, Hu Yefa, Wuhan University of Technology's journal, 1007-144X (2010) 896-04] as can be known, the detent torque of the generator of rated power P=300W is about 0.3Nm, and the frictional force of the generator behind the employing magnetic levitation system is almost nil, considers extra friction factor, getting the starting torque of generator and rotational resistance distance and Me is 0.4Nm, the starting torque coefficient Cm of S wind wheel is 0.35, and starting wind speed V is 2m/s, and rated wind speed V0 is 7m/s, safe demeanour is 45m/s, the incoming flow density p is 1.25kg/m3, and reliability coefficient μ is 1.5, and generator efficiency η 1 is 0.85; Transmission efficiency η 2 is that the best tip-speed ratio λ H of 0.9, H type wind wheel is 5; The best power coefficient CPH that the best tip-speed ratio λ S of S type wind wheel is 1.0, H type wind wheel is 0.4; The best power coefficient CPS of S type wind wheel is that 0.3, H wind wheel blade diameter length ratio j is 1.25, and the number of blade is 3, but the above equation of substitution can obtain: table 2:
