Description
Technical field
The utility model relates to a kind of one and drags many vertical shaft wind generator systems.
Background technique
Current large-scale vertical wind-driven generator structure is generally wind energy conversion system band electrical power generators, (cut near wind speed) because the wind energy power received is little when low wind speed, at this moment the wind energy conversion system operated far does not reach rated power, and the operational efficiency of thus driven generator is also very low.When namely cutting wind speed, can start generating by drive electrical generators, but generator at this moment does not far reach rated power, thus the working efficiency of generator is very low.If what this time, wind energy conversion system drove is small power generator, this small power generator is almost operated in rated power state, then the efficiency of generator just improves greatly, that is, along with the change of wind-force, if the power of the generator that wind energy conversion system drags can change, then the power of wind energy conversion system and generator can be substantially kept to match state.
Model utility content
The utility model is in order to solve the problem, propose a kind of one and drag many vertical shaft wind generator systems, native system uses a wind energy conversion system driving plurality generator, varying in size according to wind-force, the entirety that conveniently can adjust generator drops into the power of generating, matches all the time in the process that the power of wind energy conversion system and generator is changed at wind speed.
To achieve these goals, the utility model adopts following technological scheme:
A kind of one drags many vertical shaft wind generator systems, comprise vertical axis windmill, generator, controller, wind speed detection device and support platform that multiple rated power is identical, wherein, described vertical axis windmill is fixed in support platform, described generator is uniformly distributed in around vertical axis windmill along the center of vertical axis windmill, described vertical axis windmill controls the incision of each generator by controller and cuts out, and controller connects wind speed detection device, receives the real-time wind speed that it gathers.
The power of described generator is less than the power of wind energy conversion system, and the rated power sum of all generators equals the rated power of wind energy conversion system.
Preferably, described generator number is 2-4.
Based on a controlling method for said system, comprise the following steps:
(1) wind speed detected is transferred to controller by wind speed detection device;
(2) controller judges whether wind speed reaches incision wind speed, if arrive incision wind speed, a generator comes into operation by controller;
(3) controller reads real-time wind speed, according to current wind speed and rated wind speed value, drops into other generators successively.
In described step (1), wind speed detection device obtains wind power P formula according to wind energy conversion system:
ρ is air density, and υ represents wind speed, C
pbe power coefficient, A represents wind energy conversion system wind sweeping area.
The concrete grammar of described step (3) is: the number of units controlling the generator of access according to the size of wind power matches.
In described step (3), when the quantity of generator is 4, control access First generator when wind speed reaches incision wind speed, when wind speed reaches 66% of rated wind speed, power of fan exceedes rated power
this Time Controller accesses second generator; When wind speed is 85% of rated wind speed, power of fan exceedes rated power
this Time Controller accesses the 3rd generator; When wind speed is 92% of rated wind speed, power of fan exceedes rated power
this Time Controller accesses the 4th generator.
Working principle of the present utility model is: the utility model can increase cut-out wind speed, improves the wind-driven generator operating time.During strong wind, even if the structure of one-to-one can work on according to the reliability of wind energy conversion system, but due to generator overburdening generating, have to cut out, waste the wind energy of high wind speed.One drags many vertical axis aerogenerators, namely wind energy conversion system can driving plurality generator, determine according to the difference of wind speed to access the number of units run, reach the power of wind-driven generator and mating of wind energy power, improve the overall performance of wind-driven generator, reach raise the efficiency, the object of energy-conservation, consumption reduction.
The beneficial effects of the utility model are:
(1) can reduce incision wind speed, increase generating dutation: owing to only having a generator operation when starting, load is little, wind energy conversion system can drive electrical generators easily, realizes operating at full capacity of generator;
(2) in the running generated electricity, wind-force acc power and generator overall power match all the time, and every platform generator all groundwork, in rated condition, improves the working efficiency of generator; Instead of when resembling with a generator, during just incision generating, because wind speed is little, generator speed is low, and away from rated condition, efficiency is low;
(3) the utility model can increase excision wind speed, improves the wind-driven generator operating time;
(4) the utility model one drags many structures, according to the generator of wind-force size adjustment access, in tolerance range, can ensure that generator normally works, so the utility model can also expand work wind speed range at wind energy conversion system.Namely add number when generating electricity in year.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is control multiple stage generator of the present utility model incision excision system layout;
Fig. 3 is control system figure of the present utility model.
Wherein, 1, wind energy conversion system; 2, generator; 3, support platform.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Figure 1-Figure 2, the utility model is achieved through the following technical solutions, and comprises a vertical axis windmill, multiple stage generator, incision and excision controller, the control strategy of wind speed detection device and controller.According to wind conditions, can the incision of each generator be carried out and cut out control, with the coupling of the best of the output power and generator set that keep wind energy conversion system, improve generating efficiency.Control block diagram is shown in Fig. 3.
A wind energy conversion system drives 2-4 platform generator the most suitable, drags four to carry out describing below by one.
Wind energy formula is obtained according to wind energy conversion system
the wind speed detected is given controller by wind speed detection device.
When wind speed reaches incision wind speed, First generator starts generating, and this incision wind speed one is lower than the incision wind speed of existing one-to-one, because according to thought of the present utility model, the power of separate unit generator is less than the power of wind energy conversion system.
When wind speed is 63% of rated wind speed, power is full power
this Time Controller accesses second generator;
When wind speed is 80% of rated wind speed, power is full power
this Time Controller accesses the 3rd generator;
When wind speed is 90% of rated wind speed, power is full power
this Time Controller accesses the 4th generator.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
