Further, 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 that end is all actually on the control section in controller of fan 5.The power supply electricity of this control section
Source can be the power supply of special setting, it would however also be possible to employ above-mentioned super capacitor realizing powering, due to control section power supply not
Belong to utility model point of the present utility model, so, just no longer specifically describe here.Further, since this control section has specially
Power supply power, so when catalyst 2 disconnects, having no effect on the power supply of control section.
Based on above-mentioned brakes, this utility model provides a kind of braking method, is illustrated in figure 2 this brake control method
Be embodied as flow chart.Vertical axis aerogenerator 1 enters control for brake in the presence of controller of fan 5, so, this system
Flowing control method is the software program being arranged in controller of fan 5 control section, and this software program with timing scan or is determined
When the mode interrupted implement in controller of fan 5.
Normal when running between vertical axis aerogenerator 1 and controller of fan 5 catalyst 2 close, with super capacitor 8 it

Catalyst 2 between 1 and controller of fan 5, the contacts status signal (i.e. cut-off signal) of catalyst 2 feeds back to controller of fan
5.In braking, the catalyst 2 disconnecting between vertical axis aerogenerator 1 and controller of fan 5 is needed to be that system is carried out first
A kind of protection because once breaking down, controller of fan 5 is likely to have no idea by the energy of vertical axis aerogenerator 1
Amount is fed to electrical network;Or in the case of wind speed super large, braked by way of energy feeding by force and easily cause super electricity
The overload holding 8 is damaged.
The return signal of the contact according to catalyst 2 for the controller of fan 5 judges whether catalyst 2 is already off, if disconnecting
Then control the catalyst 3 between closure vertical axis aerogenerator 1 and super capacitor charger 6, realize the storage of braking energy.
Further, super capacitor charger 6 can be braked the energy stores of process, current control by constant current charge mode
Amount can be planned in conjunction with blower fan revolving property, so that blower fan braking is quick, steadily.And, the contacts status of catalyst 3
Signal feeds back to controller of fan 5.With the carrying out charged, the rotating speed of vertical axis aerogenerator 1 is gradually lowered.
According to the contact return signal of catalyst 3, controller of fan 5 judges whether catalyst 3 closed, if closure and
When the rotating speed of vertical axis aerogenerator 1 is reduced to 0 after super capacitor 8 charging braking, controls and disconnect catalyst 3, terminate to make
Dynamic recover energy storage in super capacitor 8, control closure catalyst 4 simultaneously, carry out short circuit braking using short circuit piece, simultaneously to
Electromagnetic brake 10 sends brake command.The contact signal of catalyst 4 feeds back to controller of fan 5.Short circuit piece 7 Main Function
It is to increase braking torque;Electromagnetic braking Main Function is the fastening fan rotor when the rotating speed of fan rotor is zero, prevents blower fan

In addition, when vertical axis aerogenerator starts, start-up course is completely contrary with braking procedure operation, releases first
Electric discharge magnetic-type brake 10, disconnects catalyst 4 and catalyst 3, and then closure catalyst 2 carries out air-blower control or grid-connected
Electricity.
In this brakes, super capacitor charger Main Function is the mechanical energy of blower fan to be converted into power storage exist
In super capacitor.Super capacitor can be for being specifically used to store the energy storage device of braking energy, it is, of course, also possible to send out as wind-force
The UPS stand-by power supply of electric system is it is achieved that the recycling of braking energy.This UPS stand-by power supply possesses two kinds of purposes, normal fortune
During row from AC network obtain electric as system reserve power supply, during braking store blower fan braking energy.Further, since in non-brake feelings
By alternating current, super capacitor is charged under condition, then be accomplished by ensureing that charging voltage value setting leaves certain allowance, because
For ease of blower fan braking energy being all stored in super capacitor in Braking system.
Further, since catalyst and electromagnetic brake depend on Electromagnetic Control, therefore can sentence in the way of using time delay
Disconnecting tentaculum and electromagnetic brake whether fault, comprehensive operation instructions, such as adopt 100ms delay judgement state to return letter
Number mode accurately can judge whether fault, if that is, controller of fan is after sending control signal during time delay 100ms,
Controller of fan is not received by state return signal, then, represent faulty;Otherwise, judge the control of controller of fan output
Whether signal processed is consistent with catalyst state return signal or electromagnetic brake state return signal, if unanimously, represents
Fault-free, otherwise, represents fault.
When breaking down, carry out the order switching system of catalyst and electromagnetic brake by delays time to control mode
Dynamic, to ensure fan safe.
Blower fan braking procedure should execute in strict accordance with braking process step, starts alternate brake after brake fault
Process operation, and report backstage brake fault information.
Due to after catalyst fault, it is not known that the time of day of catalyst, the probability that three catalysts damage simultaneously is almost
For 0, once but certain catalyst break down, system is also performed at brake hard in addition to carrying out fault message up sending
Reason.Specific embodiment is:Once catalyst fault occurs, issue first catalyst 2 disconnect, catalyst 3 close commands, do not examine
Look into contact return signal, time delay 20s (experiment test blower fan is decelerated to for 0 time from rated wind speed through storage brake) issues and connects
Tentaculum 3 disconnects, catalyst 4 close commands, and time delay 5s issues electromagnetic braking order.Blower fan end of braking.
In above-described embodiment, in braking procedure, status information must be returned to wind after disconnection or closure by catalyst
Machine controller, wind control device can determine the state of catalyst according to return information, carries out follow-up control, this control with this
Mode processed is more accurate.Certainly, as other embodiments, when controlling, the action of a control contactor, non-return state is believed
Breath, although this control mode does not have the control mode in above-described embodiment accurate, is also to be fully able to implement.
In above-described embodiment, the controlling switch in brakes switchs for electronic control type, realizes controlling by control device, as
Other embodiments, these controlling switches can also be that Non-follow control type switchs, in braking directly by manually controlling, such
Words, are no need in this brakes arranging control device.
