Description
Technical field
The present invention relates to wind electric converter fields, and in particular to a kind of to use switched reluctance machines as variable speed wind generating
Machine, based on become the lower biswitch magnetic resistance wind-driven generator unit of generating voltage control integrate unsteady flow and high voltage direct current exports it is low at
Originally, the converter system of high reliability and its regulation and control method.
Background technology
Switched reluctance machines are simple in structure firm, and manufacturing cost is cheap, and without winding, without permanent magnet on rotor, reliability is high,
It has broad application prospects.
Direct current transportation in recent years is increasingly subject to the attention of power department, and just tool is young in some areas for the DC grid of local
Thus shape, high pressure, super-pressure, extra-high voltage direct-current transmission and grid-connected also in development, has also derived more and more load equipments
Directly DC power supply is used to power.
Switch reluctance generator is generally placed in by 2-5 phase winding on stator, according to salient pole between rotor and groove
Relative position determines the phase winding being powered, and is generally divided into excitation and two big stages of power generation when work per phase winding, the excitation stage is
Motor phase windings absorb the electric energy storage magnetic energy of external field power supply, subsequently terminate the excitation stage according to rotor relative stator position
Into power generating stage, the magnetic energy stored in phase winding is converted into electric energy output.
The excitation of switch reluctance generator, power generation will surround the operation control realization for the convertor circuit for connecting its winding,
There is no winding convertor circuit, switch reluctance generator is naturally without in all senses.
It is preferably reliability height, simple structure, convenient control, otherwise winding convertor circuit event in the design of winding convertor circuit
Barrier means that this generating set will stop power generation operation completely, very crucial；It considers simultaneously under most occasions to outlet side
The demand of high voltage, if it is possible to realize the function of boosting in winding convertor circuit, then certainly will have very much practical significance.
Conventional switch reluctance generator converter system is usually that every generator individually corresponds to a set of converter system, if
Two or more switch reluctance generator units share a set of converter system, not yet occur at present, also unrealistic.
The unrealistic reason of a set of converter system is shared based on above-indicated more switch reluctance generator units, one
Then under wind-powered electricity generation operating mode, wind speed, rotating speed that different units face etc. can be variant, to which the parameters such as respective output power, voltage are deposited
In the possibility of difference；In addition, according to the electromagnetic theory of switch reluctance generator, generally require to carry out maximum work under wind-powered electricity generation operating mode
Rate point tracks (MPPT) control, and to obtain maximum power output, and a kind of control strategy is exactly to control output voltage to generate electricity electricity
Pressure dynamically with Based Motional Electromotive Force keep balance (or individually reduce generating voltage so that power generating stage winding current downward trend
Slow down or rise, to enhance electric energy fan-out capability), to which winding current is flat-topped wave, the ability for exporting electric energy is maximum,
Be conducive to the improvement to torque pulsation, and Based Motional Electromotive Force random groups rotating speed and change, in different unit allocations naturally so that
Respective generating voltage follows adjustment in response to the needs of maximum power output according to Based Motional Electromotive Force that may be different, this
It causes the generating voltage of the respective output end of different units different, obstacle is brought to share a set of converter system.
The stability of the field power supply of switch reluctance generator, separate excitation type is good, the voltage and current fluctuation of traditional self-excitation type
Larger, this is also the third factor for causing different unit generation voltage differences；In order to reduce interference, often field power supply end applies
Isolation link；In general, in power generation outlet side, no matter it is directly output to DC load or is incorporated to DC grid, reliability
Under it is required that, it is also desirable to electromagnetic isolation link；Electrical between two units if if two unit converter systems capable of being combined
Wiring is necessarily also required to be isolated；Based on the above as it can be seen that excessive transformer uses, cost and loss certainly will be increased.
In the MPPT and Energy optimization control of switch reluctance generator, the generating voltage or hair to output end are generally required
Electric current is controlled, and switching tube quantity and the complexity of control are increased, if can establish on the basis of other Functional Designs
It kills two birds with one stone simultaneously and completes multifunction control, then must have development prospect, including unsteady flow system under the premise of meeting reliability
Electromagnetic isolation link of system etc..

Description of the drawings
Fig. 1 show the present invention and becomes generating voltage lower switch magnetic resistance wind-driven generator high pressure converter system structure chart.
Specific implementation mode
Two switch reluctance generators of the present embodiment are four phase windings, are respectively A/ by the sequence being distributed on stator
Tetra- phase winding of B/C/D and M/N/P/Q, as shown in Fig. 1.
Attached drawing 1 show the present embodiment and becomes generating voltage lower switch magnetic resistance wind-driven generator high pressure converter system circuit structure
Figure, the first unsteady flow main circuit 101 is identical with 102 internal structure of the second unsteady flow main circuit, and selected component is identical,
Operation principle is identical, opposite according to the switch reluctance generator rotor detected by taking the first unsteady flow main circuit 101 as an example
The location information of stator, it is assumed that the first phase winding A needs are devoted oneself to work, then first switch pipe V1 and second switch pipe V2 closures are led
Logical, it (is to be stored by first when the switch reluctance generator is dynamic that the electric energy of the first field circuit output is provided to the first phase winding A
Battery X1 is provided via the first diode D1) electric energy needed for excitation waits for into the excitation stage according to rotor-position and winding current
Information needs to turn off the magnetic energy stored in first switch pipe V1 and second switch pipe V2, the first phase winding A via the second diode
D2 and third diode D3 provides afterflow power generation access and exports outward, this is power generating stage, and output end voltage is the electricity that generates electricity
Pressure waits reaching certain rotor-position (rotor with salient pole center line and stator where the phase winding according to switch reluctance generator model
Groove center line overlapping positions) when, since rotor air gap is maximum at this time, magnetic resistance is maximum, and winding inductance is minimum, according to switch magnetic
Generator mathematical model is hindered, then winding current will drastically decline until to zero to terminate the work of the first phase winding A；Other phases
The operating mode of winding is similar, and the second phase winding B excitation stages were the 4th switching tube V4 and the 5th switching tube V5 is closed conducting, hair
The electric stage is that the 5th diode D5 and the 6th diode D6 generate electricity for its afterflow；The third phase winding C excitation stages are first switch
Pipe V1 and third switching tube V3 is closed conducting, and power generating stage is that third diode D3 and the 4th diode D4 generate electricity for its afterflow；
4th phase winding D excitation stages were the 4th switching tube V4 and the 6th switching tube V6 is closed conducting, and power generating stage is the 6th diode
D6 and the 7th diode D7 generates electricity for its afterflow；First capacitor C1 plays the role of filtering and voltage support, energy storage, capacitance
Value can neither it is excessive can not be too small, since it is considered that by the 8th diode D8, the first inductance L1, the 7th switching tube V7, absorb
The normal work for change generating voltage circuit, that is, bleed-off circuit that device 1 forms, the first capacitor C1 both end voltages are generating voltage,
In the controls such as the MPPT of switch reluctance generator or maximal efficiency, according to switch reluctance generator mathematical model, when movement electricity
When kinetic potential is equal to generating voltage, the electric energy fan-out capability of switch reluctance generator is most strong at this time, and Based Motional Electromotive Force is wind turbine
The function of group rotating speed, and wind speed is variation often, so for variable-speed wind-power system, generating unit speed must also follow tune
It is whole, to cause the dynamic change characterization of Based Motional Electromotive Force, in order to improve base speed system generating capacity below, latest model at present
Controling parameter be exactly to regulate and control to generating voltage, the embodiment of the present invention just devises the change that several components as shown above are constituted
Generating voltage circuit, when the 7th switching tube V7 is closed conducting, the energy storage of the first capacitor C1 to the first inductance L1 transfers to
Its both ends generating voltage reduces, to be checked to measure after generating voltage reaches satisfied value or balance each other with Based Motional Electromotive Force, shutdown the
Seven switching tube V7, the at this time energy storage of the first inductance L1 are released via the 8th diode to absorber 1, and absorber 1 can be simple
Resistive load, can also be that energy storage equipment is such as used to help the first dynamic accumulator X1 of switch reluctance generator, may be used also
To be that other energy storage equipments are used for power supply needed for illumination etc.；In addition, bleed-off circuit is not merely for keeping Based Motional Electromotive Force and hair
The balance of piezoelectric voltage is in fact also unable to reach balance in certain extreme cases, still, according to switch reluctance generator mathematics
Model, although winding current will be flat-topped wave when generating voltage and Based Motional Electromotive Force balance, correspondingly, the tune of generating voltage
The trend that winding current can be changed in nature is saved, according to switch reluctance generator mathematical principle, when generating voltage is electronic less than moving
When gesture, power generating stage winding current will be in rising trend, otherwise is downward trend, naturally, in order to improve electric energy fan-out capability, especially
It is when the base speed of Wind turbines is following, it is undesirable to which winding current is on a declining curve in power generating stage, so passing through this reality
Apply the bleed-off circuit of example, reduce generating voltage value, reduce its difference between Based Motional Electromotive Force naturally, so as to improve around
Group current waveform trend, can at least reduce winding current downward trend, improve power generation fan-out capability and pulsation of current rate, from
And it is also helpful to the reduction of torque pulsation；Note that being always separated by stator in this 101 structure of the first unsteady flow main circuit (is not
It is adjacent) winding constitute one group and share a upper switch pipe, i.e. the first phase winding A and third phase winding C share first switch pipe
V1, the second phase winding B and the 4th phase winding D share the 4th switching tube V4；As for where second switch reluctance generator
