Description
Technical field
The present invention relates to a kind of novel wind generator group, the disperse power cumulative that will form on a plurality of less wind wheels by " multi-pressure point paddle wheel formula water turbine " especially realizes concentrating the wind power generating set and the system thereof of high-power generating target.
Background technique
The facing the wind design form of wind energy conversion system of rotary wind power generating set and employing thereof of horizontal axis leaf oar, it is most widely used general, wind energy conversion system type that specifications and models are the most complete in the current global wind-powered electricity generation unit equipment kind, it is the product based on less rotor diameter at first, the microphyll oar facing the wind rotary wind energy conversion system have design, manufacturing, installation, use simple and convenient, the wind wheel rotational speed is very fast, wind wheel is all very strong with wind energy power, wind energy transfer capability, many particular performances advantages such as the wind wheel rotary head is flexible to the wind mode, and rotational structure is simple.
But along with the propelling and the development of the high-power demand of wind-powered electricity generation unit, the facing the wind rotor diameter of rotary wind-powered electricity generation unit of horizontal axis leaf oar is progressively strengthening, and current external relatively large wind wheel swing has reached 126 meters.Yet practical data and application result prove really, be amplified under the situation that exceeds certain region limits scope when the wind wheel rotating diameter, the development trend of decline gradually and even rapid variation just will appear in its performance index, and this trend is along with transfiniting of rotor diameter amplified the situation that presents the geometrical progression aggravation.
In decline rapidly, cause the degree of effectively utilizing of high-quality wind field wind energy resources significantly to reduce as: the ability of exerting oneself that wish to increase and the required ratio that cooperates the wind wheel rotation wind sweeping area that increases; The revolution aggravation of its unit time rotation descends, and the gearbox drive ratio that causes needs to cooperate sharply rises, thereby causes the significantly increase of gear box designs difficulty of processing and equipment volume; It causes cost of material and manufacture cost significantly to improve to the demand fast lifting of the strength of materials; It is regulated and control frequency modulation and the wind difficulty is significantly strengthened, and causes adjusted and controlled complexity, the regulation and control difficulty, and regulating effect is relatively poor, and rate of fault significantly increases; Comprise in addition: tall and big " long-armed " that it constantly shakes very influences scenic spot, city view and people's visual environment, because people's eyes have the habit of " the tall and big movable object of always preferential seizure "; " long-armed " also is difficult to avoid the impact of high strength typhoon to be rocked; The operation noise of its formation increases gradually and even is very serious etc.
Therefore, approach the wind-powered electricity generation unit of MW class and above unit power output ability thereof design, all suggestion adopt 07 year the last word patented technology " combined wind-focusing superpower; combination air collecting galactic power and rotary-type very big power wind power generating set thereof " three be suitable for the unit super large greatly, the exert oneself wind energy conversion system type form of ability design of superpower, it can be realized surpassing 20-50 megawatt and above unit power output ability design thereof like a cork and can form easily that the step mode of exerting oneself designs and mutual conversion and conveniently regulating and controlling between it, can bring cost, serial comprehensive advantage such as efficient can be suitable for various wind-force respectively, wind direction adopts down with weather conditions with geographical.
Yet, aforementioned many comprehensive advantages that small-sized " leaf oar facing the wind rotary wind energy conversion system " has are that " combined wind-focusing three big innovation types " formed advantage is difficult to substitute, especially install flexibly under the situation of application in medium and small dispersion, therefore need transform its Achilles heel that has, make its reinforcement.Analyzing middle-size and small-size " leaf oar facing the wind rotary wind-powered electricity generation unit " maximum application power deficiency is that its unit power output ability is extremely low, it is very difficult thing that the user needs respectively numerous the small generators that disperse to be arranged on the wind-powered electricity generation unit to be carried out effective frequency modulation simultaneously, regulate and control, are incorporated into the power networks to control, therefore causing some electrical network departments to list the electric power of its generation in influence the gentle stable operation of electrical network manufacturer treats, makes it be difficult to positive admittance; In addition, generally have only 60%-70% with the energy transformation efficiency of generator that high-power generator is smaller, and high-power generator can reach more than 93%.
Chinese invention patent [200510120802] has proposed the technical solution of " a kind of wind power generating set and system " and the technological scheme of the present invention's proposition has partial content close, all are the wind-powered electricity generation machine set system designs that adopt " with a plurality of dispersion wind-force power and energy that on little wind wheel, form; be equipped with; make and disperse hydraulic power to compile the concentrated huge ability of exerting oneself of formation, thereby form the high-power wind turbine generating capacity " by hydraulic power conversion equipment and the integrated of Hydraulic Power Transmission System device.That is: be directly to be connected on each " oil hydraulic pump " of cooperation with it behind with being delivered at first respectively at the disperse power that forms on each wind wheel at wind wheel separately, form the disperse power of hydraulic pressure form by its conversion, be pooled to same " oil hydraulic motor " by the Hydraulic Power Transmission System device again and go up the concentrated power output of formation, then by should " oil hydraulic motor " cooperating the bigger generating capacity of formation with a powerful generator.
Yet, rotary hydraulic motor) and existing commonly used its " rolling rotor-type oil hydraulic motor " that adopts (or is called:, the project organization that all hydraulic power fluid conversion equipments of freely selecting can be provided all present with the mode of exerting oneself " exert oneself transfer capability with form efficient lower (this is caused by its fluid way of propelling and global design structure); or complex structure; or bulky; or the unit conveyance capacity that forms is lower; or be difficult to effective regulation and control of the ability of exerting oneself, or the above-mentioned condition while is multinomial and deposit " etc. many-sided problems and shortcomings.
As: " rolling rotor-type oil hydraulic motor " especially exerts oneself in forming big flow set after the conversion demand (because the unit conveyance capacity that its mode of action can form is very low, concentrate big conveyance capacity to need the equipment of large volume to finish), it just needs large-scale " rolling rotor-type oil hydraulic motor " to finish, and its structure also needs to form " labyrinth of multi-cavity integrated design in parallel " could form the stable effect of exerting oneself of rotating operation, even so its transfer capability of exerting oneself also is very low, these all will cause above-mentioned " dividing energy-cumulative " power generation system design route to be difficult to desirable the realization, and therefore the problem of " oil hydraulic motor " just becomes its maximum resistance and crucial deficiency.
But up to the present, existing for other " oil hydraulic motor " of freely selecting, or other " by fluid dynamic to the mechanokinetic conversion equipment " also do not have even more ideal technical solution to be used to provide.
At the beginning of 2004, the patent of invention technological scheme of fluid dynamic machinery conversion equipment of the brand-new type of a kind of " upright, horizontal axis multi-pressure point paddle wheel formula water turbine and power station supporting facility " thereof [Chinese invention patent number: 200410004451.9] has been proposed by patent same Applicant of the present invention, its design object originally is to be applied on various types of water power plants, is particularly suitable for adopting on various types of medium waterpower generator stations.General introduction to its project organization and the mode of action is: it is the maximum moment place of same " paddle wheel runner " that high-pressure water flow is provided with around the center at each setting-out structure with tangent direction, multiple pressure point mode, with the form acting in conjunction of direct repressive impact, thereby makes high-pressure hydraulic be converted into the rotating machinery power energy expeditiously.
The advantage performance of its formation is numerous, comprise: the mode of action that adopts the direct repressive promotion runner of tangent line to exert oneself, can make the transfer capability of exerting oneself of current (or working solution stream) very powerful, its structure is simple and direct especially, the runner volume is little, but the unit conveyance capacity is very powerful, and runner has diameter and high long bi-directional design ability to expand space, and the energy utilization is very abundant with conversion, also is difficult to form the common problems of existing type water turbine such as cavitation corrosion, abrasion, vibration, leakage loss, efficiency area restriction;
Adopt the multiple pressure point mode can make the runner speed governing, transfer the power mode simple and convenient, scope is huge and even become several times, can adopt the control mode of closing several setting-out structures can save the water energy of hydropower reservoir station exponentially in the sub load period; Its vertical integrated water transport pipeline design form makes its structure more compact ...
