Kweli phepha, indlela entsha esekelwe kwingqiqo yomlawuli iphuhliswe kwi-PVWPS. izicelo ezibandakanya iindlela zokunciphisa ilahleko ezisetyenziswa kwiimotor induction motors (IM) .Ulawulo olucetywayo lukhetha ubukhulu obuphezulu be-flux ngokunciphisa ilahleko ye-IM.Ukongezelela, indlela yokujonga ukuguquguquka okuguquguqukayo nayo yaziswa.Ukufaneleka kolawulo olucetywayo kuqatshelwa ngu ukunciphisa i-sink current;ngoko ke, ilahleko yemoto iyancitshiswa kwaye ukusebenza kakuhle kuphuculwe.Isicwangciso solawulo esicetywayo sithelekiswa neendlela ngaphandle kokunciphisa ilahleko.Iziphumo zothelekiso zibonisa ukuphumelela kwendlela ecetywayo, esekelwe ekunciphiseni ilahleko kwisantya sombane, ukufunxa okwangoku, ukuqukuqela. amanzi, kunye nokuphuhlisa i-flux.Uvavanyo lwe-processor-in-the-loop (PIL) lwenziwa njengovavanyo lovavanyo lwendlela ecetywayo.Ibandakanya ukuphunyezwa kwekhowudi ye-C eyenziweyo kwibhodi yokufumanisa i-STM32F4.Iziphumo ezifunyenwe kwi-embedded ibhodi ziyafana neziphumo zokulinganisa amanani.
Amandla ahlaziyekayo, ngakumbiilangaiteknoloji ye-photovoltaic, inokuba yinto ecocekileyo kumafutha e-fossil kwiinkqubo zokumpompa amanzi1,2.Iinkqubo zokumpompa i-Photovoltaic zifumene ingqwalasela enkulu kwiindawo ezikude ngaphandle kombane3,4.
Iinjini ezahlukeneyo zisetyenziswa kwizicelo zokumpompa zePV.Inqanaba eliphambili lePVWPS lisekelwe kwiimoto ze-DC.Ezi motors zilula ukulawula nokuphumeza, kodwa zifuna ukugcinwa rhoqo ngenxa yobukho bee-annotators kunye neebrashi5.Ukoyisa le ntsilelo, i-brushless iinjini zemagnethi ezisisigxina zaziswa, ezibonakaliswe nge-brushless, ukusebenza kakuhle kunye nokuthembeka6.Xa kuthelekiswa nezinye iinjini, i-PVWPS esekelwe kwi-IM inomsebenzi ongcono kuba le moto inokwethenjelwa, inexabiso eliphantsi, ingenakugcinwa, kwaye inikezela ngamathuba amaninzi okulawula amaqhinga7. .Ubuchule boLawulo lweNkatha engathanga ngqo (IFOC) kunye neendlela eziNgqo ngoLawulo lweTorque (DTC) ziqhele ukusetyenziswa8.
I-IFOC yaphuhliswa nguBlaschke kunye neHasse kwaye ivumela ukutshintsha isantya se-IM kuluhlu olubanzi9,10.I-stator yangoku ihlulwe ibe ngamacandelo amabini, enye ivelisa i-magnetic flux kwaye enye ivelisa i-torque ngokuguqula inkqubo yokulungelelanisa i-dq.Oku kuvumela ulawulo oluzimeleyo lwe-flux kunye ne-torque phantsi kweemeko ezizinzileyo kunye neemeko eziguquguqukayo.I-Axis (d) ihambelana ne-rotor flux space vector, ebandakanya icandelo le-q-axis ye-rotor flux space vector isoloko i-zero.FOC ibonelela ngempendulo elungileyo nekhawulezayo11 ,12, nangona kunjalo, le ndlela inzima kwaye ixhomekeke kwiinguqu zeparameter13.Ukoyisa ezi ntsilelo, i-Takashi kunye ne-Noguchi14 yazisa i-DTC, enokusebenza okuphezulu okuguquguqukayo kwaye yomelele kwaye ingaphantsi kwe-parameter utshintsho.Kwi-DTC, i-torque ye-electromagnetic kunye ne-stator flux zilawulwa ngokukhupha i-stator flux kunye ne-torque kuqikelelo oluhambelanayo.Isiphumo sondliwa kwi-hysteresis comparator ukuvelisa i-vector yombane efanelekileyo ukulawula.zombini i-stator flux kunye ne-torque.
Ukuphazamiseka okuphambili kwesi sicwangciso solawulo yi-torque enkulu kunye nokuguquguquka okuguquguqukayo ngenxa yokusetyenziswa kwe-hysteresis regulators kwi-stator flux kunye ne-electromagnetic torque regulation15,42.I-Multilevel converters isetyenziselwa ukunciphisa i-ripple, kodwa ukusebenza kakuhle kuncitshiswa ngenani lokutshintsha kwamandla16. Ababhali abaliqela basebenzise i-space vector modulation (SWM)17, sliding mode control (SMC)18, ezizindlela ezinamandla kodwa zinengxaki ye-jittering engafunekiyo19.Abaphandi abaninzi basebenzise ubuchule bobukrelekrele bokwenza ukuphucula ukusebenza komlawuli, phakathi kwabo, (1) i-neural amanethiwekhi, isicwangciso solawulo esifuna iiprosesa zesantya esiphezulu ukuphumeza20, kunye (2) ne-algorithms yofuzo21.
Ulawulo olungekho ngqiqweni lunamandla, lufanelekile kwiindlela zolawulo olungenamgca, kwaye alufuni ulwazi lwemodeli echanekileyo.Kubandakanya ukusetyenziswa kweebhloko zengqiqo ezingenangqondo endaweni yabalawuli be-hysteretic kunye nokutshintsha iitafile zokukhetha ukunciphisa i-flux kunye ne-torque ripple.Kufanelekile ukubonisa ukuba Ii-DTC ezisekelwe kwi-FLC zibonelela ngentsebenzo engcono22, kodwa akwanelanga ukwandisa ukusebenza kakuhle kwe-injini, ngoko ke iindlela zokulawula i-loop ziyafuneka.
Kuninzi lwezifundo zangaphambili, ababhali bakhetha ukuguquguquka rhoqo njengereferensi yereferensi, kodwa olu khetho lwereferensi alubonisi uqheliselo olufanelekileyo.
Ukusebenza okuphezulu, ukusebenza kakuhle kweemoto zokuqhuba zifuna impendulo ekhawulezayo nechanekileyo.Ngakolunye uhlangothi, kweminye imisebenzi, ulawulo lusenokungabi lulo, ngoko ke ukusebenza kakuhle kwenkqubo yokuqhuba akunakuphuculwa.Ukusebenza ngcono kunokufumaneka ngokusebenzisa. ireferensi eguquguqukayo eguquguqukayo ngexesha lokusebenza kwenkqubo.
Ababhali abaninzi baye bacebisa isilawuli sokukhangela (SC) esinciphisa ilahleko phantsi kweemeko ezahlukeneyo zomthwalo (ezifana ne-in27) ukuphucula ukusebenza kakuhle kwe-injini.Ubuchule bubandakanya ukulinganisa kunye nokunciphisa amandla okufakwayo ngokuphindaphinda i-d-axis ireferensi yangoku okanye i-stator flux. Isalathiso.Nangona kunjalo, le ndlela yazisa i-torque ripple ngenxa ye-oscillations ekhoyo kwi-air-gap flux, kwaye ukuphunyezwa kwale ndlela kudla ixesha kwaye i-computially-intensive resource.I-Particle swarm optimization ikwasetyenziselwa ukuphucula ukusebenza kakuhle28, kodwa obu buchule bungakwazi ubambeke kwiminima yendawo, ekhokelela kukhetho olulambathayo lweparamitha zolawulo29.
Kulo phepha, ubuchule obunxulumene ne-FDTC bucetywayo ukukhetha umbane ohamba kakuhle ngokunciphisa ukulahlekelwa kweemoto.Olu kudibanisa luqinisekisa ukukwazi ukusebenzisa inqanaba eliphezulu le-flux kwindawo nganye yokusebenza, ngaloo ndlela kwandisa ukusebenza kakuhle kwenkqubo yokupompa amanzi e-photovoltaic ecetywayo. Ngoko ke, kubonakala kukulungele kakhulu kwizicelo zokupompa amanzi e-photovoltaic.
Ngaphezu koko, uvavanyo lweprosesa-in-loop yendlela ecetywayo lwenziwa ngokusebenzisa ibhodi ye-STM32F4 njengobungqina bovavanyo.Iinzuzo eziphambili zale ngundoqo zilula zokuphunyezwa, ixabiso eliphantsi kwaye akukho mfuneko yokuphuhlisa iinkqubo ezinzima 30. , ibhodi yokuguqula i-FT232RL USB-UART idibene ne-STM32F4, eqinisekisa unxibelelwano lwangaphandle lonxibelelwano ukwenzela ukuseka i-port ye-serial port (COM port) kwikhompyutheni.Le ndlela ivumela idatha ukuba idluliselwe kumazinga aphezulu e-baud.
Ukusebenza kwe-PVWPS usebenzisa ubuchule obucetywayo kuthelekiswa neenkqubo ze-PV ngaphandle kokunciphisa ilahleko phantsi kweemeko ezahlukeneyo zokusebenza.Iziphumo ezifunyenweyo zibonisa ukuba inkqubo yepompo yamanzi ye-photovoltaic ecetywayo ingcono ekunciphiseni ilahleko ye-stator yangoku kunye nobhedu, ukulungelelanisa ukuguquguquka kunye nokupompa amanzi.
Eminye yephepha iqulunqwe ngolu hlobo lulandelayo: Ukubunjwa kwenkqubo ecetywayo kunikwe kwicandelo elithi "Imodeli ye-Photovoltaic Systems" .Kwicandelo elithi "Isicwangciso sokulawula inkqubo yokufunda", i-FDTC, isicwangciso esicetywayo sokulawula kunye nobuchule be-MPPT. ichazwe ngokweenkcukacha.Iziphumo zixutyushwa kwicandelo elithi "IziPhumo zokulinganisa".Kwicandelo "lovavanyo lwePIL kunye nebhodi yokufumanisa i-STM32F4", uvavanyo lweprosesa-in-loop luchazwe.Izigqibo zeli phepha zichazwe kwi " icandelo lesiphelo.
Umzobo we-1 ubonisa ukucwangciswa kwenkqubo ecetywayo ye-stand-alone ye-PV yokumpompa amanzi. Inkqubo iqulethe impompo ye-centrifugal esekelwe kwi-IM, i-photovoltaic array, ezimbini zokuguqula amandla [i-boost converter kunye ne-voltage source inverter (VSI)].Kweli candelo , imodeli ye-photovoltaic yenkqubo yokumpompa amanzi efundwayo inikezelwa.
Eli phepha lamkela imodeli ye-diode enyeilangaiiseli ze-photovoltaic.Iimpawu ze-PV cell zichazwe ngu-31, 32, kunye no-33.
Ukwenza ulungelelwaniso, i-boost converter isetyenziswa.Ubudlelwane phakathi kwegalelo kunye nombane wemveliso ye-DC-DC converter inikwe yi-Equation 34 ngezantsi:
Imodeli yemathematika ye-IM inokuchazwa kwisakhelo sereferensi (α,β) ngezi zibalo zilandelayo 5,40:
Apho \(l_{s }\),\(l_{r}\): stator kunye ne-rotor inductance, M: inductance mutual, \(R_{s}\), \(I_{s}\): ukuxhathisa stator kunye stator yangoku, \(R_{r}\), \(I_{r }\): ukumelana ne-rotor kunye ne-rotor yangoku, \(\phi_{s}\), \(V_{s}\): stator flux kunye ne-stator amandla ombane , \(\phi_{r}\), \(V_{r}\): i-rotor flux kunye ne-rotor voltage.
I-torque yomthwalo wempompo ye-centrifugal ngokomlinganiselo kwisikwere sesantya se-IM inokumiselwa ngoku:
Ulawulo lwenkqubo yempompo yamanzi ecetywayo yahlulahlulwe yangamacandelo amathathu ahlukeneyo.Icandelo lokuqala lijongene nobuchwepheshe beMPPT.Icandelo lesibini lijongene nokuqhuba i-IM ngokusekwe kulawulo lwetorque ecacileyo yomlawuli wengqiqo.Ngaphezu koko, iCandelo le-III lichaza ubuchule obunxulumene I-FLC-based DTC evumela ukumiselwa kweereferensi zokuguquguquka.
Kulo msebenzi, ubuchule be-P & O obuguquguqukayo busetyenziselwa ukulandelela indawo ephezulu yamandla.Ibonakaliswa ngokukhawuleza kunye ne-oscillation ephantsi (Umfanekiso 2) 37,38,39.
Ingcamango ephambili ye-DTC kukulawula ngokuthe ngqo ukuhamba kunye ne-torque yomatshini, kodwa ukusetyenziswa kwe-hysteresis regulators kwi-torque ye-electromagnetic kunye nokulawulwa kwe-stator flux kubangela i-torque ephezulu kunye ne-flux ripple. Indlela ye-DTC (umzobo 7), kunye ne-FLC inokuphuhlisa i-inverter vector states ezaneleyo.
Kweli nyathelo, igalelo liguqulwa libe liguquguquki elingaqondakaliyo ngokusebenzisa imisebenzi yobulungu (MF) kunye namagama olwimi.
