Principle is introduced
Wind energy power partly is to utilize wind energy conversion system that wind energy transformation is mechanical energy, is converted to electric energy by wind-driven generator then, again by controller to charge in batteries, through inverter to electric.
Existing wind power plant mostly adopts mechanical speed limit and hydraulic control technology on the motor speed-limiting protection; but in practice; because wind speed and direction changes too complicated; and physical environment is abominable; the dynamic support parts of small-sized wind power generator inevitably can cause vibration and parts damages, thereby bring disaster to unit.This device is at design luck electromagnetism speed-limiting protection; when being in " overpower " state, wind energy conversion system adds a reverse magnetic resistance moment to generator; the power that significantly increases generator and consumed; make it power greater than wind wheel output; wind speed round descends, and the tip speed ratio of wind wheel reduces, thereby reduces the wind energy utilization of fixed pitch wind wheel; reduce the wind energy that wind wheel absorbs, lower wind speed round then.
Referring to Fig. 2, Fig. 3, installing one speed probe SP on the main shaft of wind-driven generator, the signal output part of this speed probe SP meets the input end in of tachometer U1, signal output part D/A+, the D/A-of tachometer U1 connects CON+, the CON-end of single-chip microcomputer U2 respectively, and the output terminal OUT of single-chip microcomputer U2 meets the control coil LH of magnetic clutch through drive circuit QD.Deceleration dish 5 is fixed on the wind driven generator principal shaft 2, with 2 rotations of wind-driven generator main shaft.Several armature drift bolt 7 one ends are fixed on the electromagnetism speed-limiting protection device case 1, and the other end penetrates in the armature 6, and they are parallel with wind driven generator principal shaft 2.Armature 6 is coaxial with wind driven generator principal shaft 2, and it can slide along wind driven generator principal shaft 2 and armature drift bolt 7, but owing to the restriction that is subjected to armature drift bolt 7 can not rotate with respect to electromagnetism speed-limiting protection device case 1.Friction plate 4 is fixed on the armature 6, can slide along wind driven generator principal shaft 2 with armature 6.Under the normal condition, single-chip microcomputer output clutch adhesive signal, this signal is added to the two ends of Clutch Control coil LH after drive circuit QD amplifies, make armature 6 under magnetic force, the thrust that overcomes spring 3 is slided along armature drift bolt 7, drive friction plate 4 and separate with deceleration dish 5, wind driven generator principal shaft 2 can freely rotate.When wind energy conversion system is in the strong wind state, tachometer spindle speed that U1 gathers is greater than the default rotating speed, this signal input single-chip microcomputer U2, the system analysis of single-chip microcomputer U2 process, output clutch cut-off signal, Clutch Control coil LH outage, armature 6 slides at the thrust lower edge of spring 3 armature drift bolt 7, promote friction plate 4 and contact with the deceleration dish, friction plate 4 applies a resisting moment for the main shaft of wind-driven generator by deceleration dish 5, thereby makes the rotating speed of wind wheel begin to descend.Because the continuous action of resisting moment, wind speed round is limited in some speed range, has prevented the wind wheel driving and damages wind power generating set.The speed-limiting protection control system of wind-driven generator; be to control the resisting moment of generator, can control the wind speed round of wind-driven generator in good time according to the different situations of different wind regime and battery pack by the spindle speed of wind-driven generator being carried out timing monitoring.Because the speed of response of Electromagnetic Control is fast, the reliability height has guaranteed the high reliability of The whole control system.
The advantage of this speed-limiting protection theory is to have given up mechanical speed-limitation structure; two necessary moving elements of wind-driven generator have only been kept; the mechanical failure hidden danger of having got rid of mechanical speed limiting mechanism has fundamentally solved the problem of small-sized wind power generator long-term safety reliable operation.And, not being subjected to the speed limit of mechanical speed-limitation structure, the moulding of wind power generating set can be done more attractive in appearancely, and is more diversified.
The wind-power electricity generation drive end unit is equipped with wind-force speed probe SP, can respond to the size of all directions wind-force, by analytical calculation, utilizes the Single-chip Controlling rotating machinery, makes wind wheel be in the direction of wind-force maximum all the time.The design of wind wheel is adopted adjustable, can suitably regulate the blade tip angle according to the difference of wind direction.
Wind-driven generator is generally horizontal axis, upwind, three vane collocation.The wind-driven generator output power:
P＝0.5ρπR 2V 3C p
In the formula: ρ is an air density; R is the wind wheel radius; V is a wind speed; C pBe power coefficient, maximum value is 0.593.
Photovoltaic generation partly utilizes the photovoltaic effect of solar panel that luminous energy is converted into electric energy, then to charge in batteries, by inverter direct current is converted into Ac load is powered.Desirable PN junction solar cells I-V equation:
I S = I SC - I O ( e q v S / KT - 1 )
In the formula: I S, V SOutput current and output voltage for photovoltaic cell; I SC, I OShort circuit current and PN junction reverse saturation current for photovoltaic cell; K is a Boltzmann constant, K=1.38*10 23I/R, T are temperature; Q is an electronic charge, q=1.6*10 -19C
The solar electrical energy generation of this electricity generating device partly adopts solar energy biobattery plate, utilizes biological photosynthesis generating, by controller low-voltage DC filtering is boosted, and stores in the battery pack then.
Find in the experimental research, in photosynthesizer, energy in the fluctuation mode simultaneously along all path movement.This quantum effect guarantees that energy will transmit by most effective path, can instantaneously reach the destination.This process is included in the design of solar facilities, improved the conversion efficiency of solar cell greatly.
The surface design of biologic solar cell plate becomes the Organizational Structure of pyramid, adds reflection-resistent layer to reduce reflection of light.When illumination was mapped on the solar cell surface, light reached dye layer by the electrolyte generation scattering based on iodine, and dye layer is caught photon, and photon pushes basecoat to the electronics in the dye layer---the titanium dioxide semiconductor film.This thickness has only 10 microns and clear films can catch electric charge, and electronics is sent into the tin ash conductor layer.This one deck is positioned on the light reflecting board.Tin ash layer commander electronic working produces electric current.
In the design of solar electrical energy generation part-structure, consider that sun east rises the characteristics that the west falls, on battery plate, adorned the light intensity inductor, control the rotating mechanism rotation by inductor, make the biologic solar cell plate vertical with the sunlight radiation direction all the time, thereby make the illuminating area maximum.
Utilize the technology of biomass power generation direct burning, materialization conversion, biochemical conversion to be arranged, refine plant wet goods technology at present.By analyzing the pluses and minuses of each technology, adopted biochemical transformation approach when designing this device, mainly based on anaerobic digestion and extraordinary zymotechnic.Biogas fermentation is that organic substance (for carbohydrate, fat, protein etc.) under uniform temperature, humidity, pH value and anaerobic condition, through biogas flora fermentation (digestion), forms methane.The biogas that produces is sent in the biogas pressure controlling device, produced Ac, and become the current conversion that produces direct current to be stored in the battery pack through controller by biogas generator.
Storage battery plays energy adjustment in system simultaneously and balanced load two acts on greatly.It is converted into chemical energy with the electric energy of wind-driven generator and solar cell and the output of biomass power generation machine and stores, and uses when not enough for electric energy.In storage battery commonly used, mainly contain lead-acid battery, alkaline nickel storage battery and iron-nickel storage battery.Selected for use energy storage storage battery dedicated when design, battery plate adopts low antimony anticorrosion alloy, strict control alloying element proportioning, and adopt super thick pole plate (electrode thickness is 3.5mm), and improve the pole plate anti-corrosion capacity, prolonged the working life of storage battery.Owing to adopt special multicomponent alloy, improve the negative pole overpotential of hydrogen evolution, control negative pole liberation of hydrogen speed, the damage by water consumption is little, normally uses more than half a year and just need add distilled water.Adopt super thick pole plate and special pole plate prescription, improved the overcharging resisting electric energy power of storage battery, can reach 5 years working life.
We adopt advanced two mark three stage charging principle, the two accumulator structures of employing, the life-span of having improved storage battery greatly in this link in that storage battery is discharged and recharged.
Phase I: big electric current filling stage.Obtain the voltage condition of storage battery by voltage sampling circuit, when voltage during less than standard off load voltage (Voc), (maximum current is to system's value difference of different capacity to charge in batteries with its maximum current that can provide for sun-generated electric power, wind-driven generator, can be by C/5 charge rate value, C is a capacity of battery), because the electric current of solar cell and wind-driven generator is relevant with weather conditions, so the value of big electric current will be within limits.Keep large current charge to Voc, enter second stage.The level of charge of phase I can reach 70%～90%.
Second stage: the overvoltage perseverance is filled the stage.With constant mistake normal voltage (Voc) charging, reduce to Ioct up to charging current and enter the phase III.The level of charge of second stage nearly 100%.
Phase III: floating charge stage.Carry out floating charge with constant accurate float charge voltage Vf.After storage battery is full of, keep voltage in the floating charge mode.The selection of float charge voltage is particularly important to the life-span of storage battery, though 5% error also will make storage battery the lost of life half.
Referring to Fig. 4, the working procedure of the charging voltage matching controller of biogas generator:
Biogas generator will be stored in the battery pack by the Ac that biogas sends, and battery pack requires the input constant DC to press.In multi-energy resource combined electric generating apparatus, biomass power generation voltage matches controller utilizes bridge rectifier to convert the Ac that generator sends to direct current, adopt present most popular recloser constant voltage/constant current controller TSM108 monolithic IC then, the unstable direct current that is converted to is carried out voltage stabilizing.This controller can carry out voltage measurement to outlet line, and can regulate locking of switching frequency, overvoltage and undervoltage locking, therefore can will be through stable being input in the battery pack of Ac after the conversion in biomass power generation.
The concrete working principle of charging voltage matching controller is: the unstable VDC that biogas generator is exported behind bridge rectifier, after the resitstance voltage divider dividing potential drop by R1 and R2 composition, be added to the VCTRL pin of TSM108, and compare with the accurate voltage reference of the inner 2.52V of IC; Be added to ICTRL pin and the VS pin of IC after the output current of transducer then detects by current sense resistor R3 respectively, compare with the low value reference voltage of the inner 200mV of IC with voltage drop by R3.Two error signals in the inner amplification of IC can be PWM producer (built-in) after device inside carries out inclusive-OR operation provide a reference signal, to set the switch duty factor of the outside field effect transistor of IC.The PWM producer is made up of saw-toothed oscillator and comparator, and the excursion of PWM dutycycle is 0～95%.Oscillator frequency can be set by the timing capacitor between OSC pin and the ground, and this electric capacity can be got 220pF, thereby makes oscillator frequency about 100kHz.Pwm signal can directly be controlled IC output, with the field effect transistor of drive IC pin GD outside.Two of TSM108 inside operational amplifiers have just been realized the fine adjustment to commutating voltage like this, thereby have stablized output voltage.
Inverter function among the present invention mainly is that the constant voltage direct current in the battery pack is converted to Ac, uses for load; In addition; can also in circuit, increase the control function; as control photoelectric controller, wind-powered electricity generation controller, give birth to the conversion efficiency of electric controller; pass through reasonable disposition; carry out the optimal design of battery charging and prevent overcharge of a battery and overdischarge, short circuit, overload, drain charge and the automatic protective function that recovers, or the like.Control circuit can be controlled its excess-three sub-controller, according to the Natural resources condition of locality and user's demand wind energy, solar energy, biomass power generation is mediated, and to optimize allocation of resources, reduces user cost.SC system controller utilizes dsp chip to control.
Circuit design and device that the design of multi-energy resource combined electric generating apparatus is adopted make the protection speed of inverter bring up to the microsecond level, have improved the reliability of protective function.
By DC-AC high frequency chopper (frequency 20-30KHZ), with the uncontrollable DC low-voltage unsteady flow of input inverter is controlled dc high voltage, and then, realize the output of 50HZ square wave or sine wave AC by DC-AC conversion bridge circuit, cancelled the power frequency output transformer.Because the change of unsteady flow mode makes inverter realize miniaturization, high frequencyization, has improved technical order, has reduced cost.Adopt 1GBT, the magnetic core of VDMOS device and amorphous-microcrystallizing alloy material copped wave step-up coil.
Owing to adopted two step inversion methods, thus input voltage Applicable scope by broadening significantly, the superpressure of inverter all can be at rating value more than 100%.The inverter of being furnished with the drain charge device can bear the suspension voltage of wind energy conversion system and the off load voltage of photovoltaic cell, when electric energy is enough, can break away from battery pack, directly realize the unsteady flow conversion, and, solved the requirement of wind-driven generator inverter to the normal stable power-supplying of electric consumer.This inverter has improved the startup and the service requirement of inductive load, has improved the running state of inductive load, makes the safe operating life of inverter reach 10 years.
