More than one wind-driven generator is included, so, which is not only applicable to single wind-driven generator, may be also used in by multiple
The field of wind-force that wind-driven generator is constituted.Since vertical axis aerogenerator belongs to routine techniques, no longer it is carried out in detail here
It introduces, the braking system is described in detail below.
The braking system includes control device and energy storage device.
Wherein, control device is the key control unit of the braking system, can be using the controller being specially arranged come real
It is existing, it can use the control unit of wind generator system itself also to realize.Since controller of fan is not only able to control blower
The electric energy of output complies with the requirement of AC network, and realization is grid-connected, moreover, the controller of fan also has normal controller
Control function can be analyzed and be judged to the parameter of input, so that the function of corresponding control signal is exported, so, this
In embodiment, using the controller of fan in wind generator system as the control device of the braking system, control for brake is realized.
Due to not only playing the role of exporting the conversion of electric energy to motor in the controller of fan, and there is the function of normal controller,
I.e. the controller of fan includes two parts, and a part is electric energy conversion portion, and another part is control section.Due to air-blower control
Device exports routine techniques, no longer illustrates here.
In the present embodiment, energy storage device is mainly in view of super capacitor power density height and energy by taking super capacitor as an example
Enough tolerance instantaneous large-current impacts reduce braking time convenient for the instantaneous feedback of braking energy.But energy storage device is not limited to surpass
Grade capacitor, because large capacity, impact-resistant energy storage device can substitute super capacitor with the progress of energy storage technology, as
Energy storage device in braking system.
The braking system further includes three control switches, and in the present embodiment, these three control switches are contactor.It connects
Tentaculum band auxiliary contact, can be realized by control signal and are closed to contactor, turn off control.Certainly, as other
Embodiment, control switch can also be other electronic control type devices, such as full-controlled switch device IGBT etc..
As shown in Figure 1, three control switches are contactor 2, contactor 3 and contactor 4 respectively.Vertical axis aerogenerator
1 armature lead-out wire 9 is the component part of vertical axis aerogenerator 1, the power output as vertical axis aerogenerator 1
End, electric energy output end connect one end of contactor 2 by transmission line of electricity, and the other end of contactor 2 is connected by controller of fan
AC network connects AC network specifically by the electric energy conversion portion in controller of fan；Generator armature lead-out wire 9 connects
One end of contactor 3 is connect, the other end of contactor 3 connects super capacitor 8 by super capacitor charger 6；Generator armature draws
Outlet 9 is shorted by a short circuit route, and shorting stub road string sets contactor 4 and is shorted piece 7 and (is not drawn into figure.In figure
Armature lead-out wire 9 is shorted piece 7 by the connection of contactor 4, and this connection type when contactor 4 is closed simply to illustrate that be shorted
Piece 7 can play certain braking action, thus this connection relationship in figure be not be shorted piece 7 and armature lead-out wire 9 it
Between line connecting relation, the line connecting relation being shorted between piece 7 and armature lead-out wire 9 are as follows: generator armature lead-out wire 9 is logical
It crosses a short circuit route to be shorted, shorting stub road string sets contactor 4 and is shorted piece 7).
It is shorted the working principle and the course of work of piece are as follows: being shorted piece is essentially the copper bar end for having line short circuit function
Son, when contactor 4 is closed, blower output terminal is shorted.According to Lenz's law, the air-gap flux that PM rotor is formed cannot
Mutation, if rotor rotation at this time can make to change by the magnetic flux of stator closing coil, stator coil can generate electric current
The generation of this variation is hindered, i.e. generation torque hinders rotor rotation.It is used cooperatively with blower electromagnetic brake 10, is used for blower
Control for brake after stopping.
In order to realize that control for brake, controller of fan 5 are separately connected contactor 2,3 and of contactor by signal transmission line
Contactor 4, the signal transmission line not only transmit the control that controller of fan 5 is conveyed to contactor 2, contactor 3 and contactor 4
Signal, but also the status signal that contactor 2, contactor 3 and contactor 4 feed back to controller of fan 5 can be transmitted.
In order to when the revolving speed of vertical axis aerogenerator 1 is 0, i.e., fasten blower when vertical axis aerogenerator 1 stalls
Rotor prevents blower from rotating, which further includes brake locking device, can be traditional braking braked by abrasion
Device, can also as in the present embodiment by taking electromagnetic brake as an example.The electromagnetic brake is arranged in vertical axis wind power generation
The fixed part of machine 1, for rotor to be fixed, as shown in Figure 1.When electromagnetic brake 10 is mainly used for stationary state pair
Fan rotor part is fixed, the design method for being different from conventional brake by abrasion to brake.The control of controller of fan 5 connects
Connect electromagnetic brake 10.In addition, it is anti-that carrier state can be used in the electromagnetic brake in order to further be convenient for automation control
The brake of feedback can pass through delay pattern if without feedback signal and stop to controller of fan output status signal
Vehicle and release operation.And it is used in combination with piece braking is shorted, mutual backup, redundancy protecting.Short circuit piece also can be used conducting wire and replace
In generation, complements one another for increasing braking torque with electromagnetic brake, is shorted piece 7 and is used cooperatively with blower electromagnetic brake 10,
Control for brake after stopping for blower.
In order to cooperate the control to electromagnetic brake 10, which further includes speed detector, for detecting
The revolving speed of vertical axis aerogenerator 1 is arranged in the position for being capable of detecting when revolving speed, is not drawn into Fig. 1.Controller of fan 5 is adopted
Sample connects the speed detector.
In the present embodiment, controller of fan 5 outputs (DO) control contactor 2, contactor 3, contactor 4 using digital quantity
And electromagnetic brake 10, contactor 2, contactor 3, contactor 4 and electromagnetic brake 10 status signal feed back to
Controller of fan 5 is opened as digital quantity into (DI).Controller of fan 5 judges contactor and electromagnetic type braking based on the feedback signal
The state of device, status signal judgement run through entire braking process.
In addition, since control for brake is realized in the control section in controller of fan 5, then, on above-mentioned controller of fan 5
Open and output the corresponding port on the control section held be actually in controller of fan 5.The power supply electricity of the control section
Source can be the power supply being specially arranged, and power supply can also be realized using above-mentioned super capacitor, due to control section power supply not
Belong to inventive point of the invention, so, it just no longer specifically describes here.In addition, since the control section has special power supply to supply
Electricity, so having no effect on the power supply of control section when contactor 2 disconnects.
Based on above-mentioned braking system, the present invention provides a kind of braking method, is illustrated in figure 2 the tool of the brake control method
Body implementation flow chart.Vertical axis aerogenerator 1 enters control for brake under the action of controller of fan 5, so, the braking control
Method processed is the software program being arranged in 5 control section of controller of fan, and the software program is in timing scan or timing
Disconnected mode is implemented in controller of fan 5.
When normal operation between vertical axis aerogenerator 1 and controller of fan 5 contactor 2 be closed, with super capacitor 8 it
Between contactor 3 and be shorted piece 7 between contactor 4 disconnect.Electromagnetic brake 10 is in brake release conditions.
Receive host controller brake command or enter emergency braking condition meet (such as wind speed is excessive, system therefore
Barrier) when, vertical axis aerogenerator 1 enters braking process under the action of controller of fan 5.
When host controller issues brake command or meets emergency braking condition, vertical axis aerogenerator is disconnected first
The contacts status signal (i.e. cut-off signal) of contactor 2 between 1 and controller of fan 5, contactor 2 feeds back to controller of fan
5.In braking, needing to disconnect the contactor 2 between vertical axis aerogenerator 1 and controller of fan 5 first is carried out to system
A kind of protection because once breaking down, controller of fan 5 is likely to have no idea the energy of vertical axis aerogenerator 1
Amount is fed to power grid；Or in the case where wind speed super large, is braked by way of energy feeding by force and be easy to cause super electricity
Hold 8 overload damage.
Controller of fan 5 determines whether contactor 2 is already off according to the return signal of the contact of contactor 2, if disconnecting
The contactor 3 between closure vertical axis aerogenerator 1 and super capacitor charger 6 is then controlled, realizes the storage of braking energy.
Further, super capacitor charger 6 can carry out the energy stores of braking process, current control by constant current charge mode
Amount can be planned in conjunction with blower revolving property, so that blower braking is quickly, steadily.Moreover, the contacts status of contactor 3
Signal feeds back to controller of fan 5.As charging progresses, the revolving speed of vertical axis aerogenerator 1 gradually decreases.
Controller of fan 5 according to the contact return signal of contactor 3 determine contactor 3 it is whether closed, if closure and
When the revolving speed of vertical axis aerogenerator 1 is reduced to 0 after the charging braking of super capacitor 8, control disconnects contactor 3, terminates system
It is dynamic to recover energy storage into super capacitor 8, while controlling closure contactor 4, short circuit braking is carried out using piece is shorted, while to
Electromagnetic brake 10 sends brake command.The contact signal of contactor 4 feeds back to controller of fan 5.It is shorted 7 main function of piece
It is to increase braking torque；Electromagnetic braking main function is that fan rotor is fastened when the revolving speed of fan rotor is zero, prevents blower
Rotation.
Controller of fan 5 according to the contact return signal of contactor 4 determine contactor 4 it is whether closed, if closure and
When electromagnetic brake 10 is in braking state, braking is sent to complete information on controller of fan 5.
So far the braking of vertical axis aerogenerator is completed.
So the braking process is in simple terms, connecing between vertical axis aerogenerator and controller of fan is disconnected first
Tentaculum then puts into super capacitor energy-storage braking, and investment is shorted piece braking and electromagnetic brake after blower is steadily shut down, and uses
Guarantee fan rotor fastening in increasing braking torque.
In addition, start-up course is with braking process operation completely on the contrary, releasing first in vertical axis aerogenerator starting
Discharge magnetic-type brake 10, disconnects contactor 4 and contactor 3, is then closed contactor 2 and carries out air-blower control or grid-connected hair
Electricity.
In this braking system, super capacitor charger main function is to convert power storage for the mechanical energy of blower to exist
In super capacitor.Super capacitor can be the energy storage device for being specifically used to store braking energy, it is, of course, also possible to send out as wind-force
The UPS backup power source of electric system, realizes the recycling of braking energy.The UPS backup power source has two kinds of purposes, normal to transport
When row from AC network obtain it is electric be used as system reserve power supply, blower braking energy is stored when braking.In addition, due in non-brake feelings
Charged by alternating current to super capacitor under condition, then just need to guarantee charging voltage value setting there are certain allowance, because
For convenient for blower braking energy all can be stored in super capacitor in Braking system.
In addition, can be sentenced by the way of delay since contactor and electromagnetic brake depend on Electromagnetic Control
Disconnecting tentaculum and electromagnetic brake whether failure, comprehensive operation instructions, for example letter is returned to using 100ms delay judgement state
Number mode can accurately judge whether failure, i.e., if controller of fan issue control signal after be delayed 100ms when,
Controller of fan is not received by state return signal, then, it indicates faulty；Otherwise, judge the control of controller of fan output
Whether signal processed and contactor state return signal or electromagnetic brake state return signal are consistent, if unanimously, indicated
Otherwise fault-free indicates failure.
When breaking down, the sequence switching system of contactor and electromagnetic brake is carried out by delays time to control mode
It is dynamic, to guarantee fan safe.
Blower braking process should be executed in strict accordance with braking process step, start alternate brake after there is brake fault
Process operation, and report backstage brake fault information.
After contactor failure, it is not known that the time of day of contactor, the probability that three contactors damage simultaneously is almost
Be 0, once but some contactor break down, system will also carry out at emergency braking other than carrying out failure message up sending
Reason.Specific embodiment are as follows: once there is contactor failure, issue the disconnection of contactor 2,3 close commands of contactor first, do not examine
Contact return signal is looked into, delay 20s (experiment test blower is decelerated to for 0 time from rated wind speed by storage brake), which is issued, to be connect
The disconnection of tentaculum 3,4 close commands of contactor, delay 5s issue electromagnetic braking order.Blower end of braking.
In above-described embodiment, in braking process, status information must be returned to wind after disconnection or closure by contactor
Machine controller, wind control device can determine the state of contactor according to return information, carry out subsequent control, this control with this
Mode processed is more accurate.Certainly, as other embodiments, in control, the movement of control contactor, non-return state letter
Breath is also to be fully able to implement although this control mode is accurate without the control mode in above-described embodiment.
In above-described embodiment, the control switch in braking system is electronic control type switch, is realized and is controlled by control device, as
Other embodiments, these control switches, which can also be, manually controls type switch, such in braking directly by manual control
Words, just no setting is required in braking system control device.
In above-described embodiment, which includes further including electromagnetic brake and being shorted piece except energy storage device, when
So, this is a kind of embodiment of optimization, but the present invention is not limited to described embodiment.Basic ideas of the invention
It is to carry out the recycling of braking energy using energy storage device, it is for those of ordinary skill in the art, above-mentioned not departing from
