Okwangoku, inkqubo yokuvelisa amandla e-China ye-China ye-Photovlic System ikakhulu yinkqubo ye-DC, ekufuneka ihlawule amandla ombane aveliswe yibhetri yelanga, kwaye ibhetri ibonelela ngokubhekele ngqo amandla kumthwalo. Umzekelo, inkqubo yokukhala kwelanga elasekhaya emantla ntshona kunye nenkqubo yesikhululo saseMandla ye-microwave kude ne-Grid yonke inkqubo ye-DC. Olu hlobo lwenkqubo lunobume obulula kunye neendleko eziphantsi. Nangona kunjalo, ngenxa ye-DC yoMthwalo we-DC Kunzima ukuba kwenziwe umbane we-fotovoltaic ukubonelela ngombane ukuze ungene kwintengiso njengezinto zorhwebo. Ukongeza, isizukulwana sombane siya kuthi ekugqibeleni sifezekise umsebenzi wegridi oqhagamshelwe, ekufuneka wamkele imodeli yemarike evuthiweyo. Kwixa elizayo, iinkqubo zokuveliswa kwamandla e-AC ye-Ac Potone iya kuba yeyona nto iphambili yefotovoltaic amandla.
Iimfuneko zeFotovoltaic Systemba yeNkqubo yokuNikeza
Inkqubo yokuvelisa amandla eFotovlic esebenzisa ukuphuma kwamandla e-Ac equka iinxalenye ezine: I-Photovoltaic Uluhlu, inkqubo yokuvelisa amandla e-grid inokugcina ibhetri), kwaye i-inverter licandelo eliphambili. Ifotovoltaic ineemfuno eziphezulu ze-inever:
1. Ukusebenza okuphezulu kuyafuneka. Ngenxa yexabiso eliphezulu leeseli zelanga ngoku, ukuze kwandise ukusetyenziswa kweeseli zelanga kunye nokuphucula ukusebenza kwenkqubo, kuyafuneka ukuzama ukuphucula ukusebenza kwe-inverter.
2. Ukuthembeka okuphezulu kuyafuneka. Okwangoku, iinkqubo zokuveliswa kwefotovoltaic amandla enziwa ikakhulu kwiindawo ezikude, kwaye izikhululo ezininzi zamandla azikhathalelwanga kwaye zigcinwe. Oku kufuna ukuba i-inverter ibe nesobume sesekethe, ukhetho lwecandelo elingqongqo, kwaye lifune i-Iningter ukuba isebenze imisebenzi yoKhuselo, njengokuthintela ukhuseleko lwesekethe, i-AC
I-3. I-DC ye-DC ye-DC iyafuneka ukuba ube noluhlu olubanzi lohlengahlengiso. Ukususela kwi-terminal voltage yotshintsho lwebhetri kunye nomthwalo kunye nobunzulu belanga, nangona ibhetri inefuthe elibalulekileyo kwi-voltage yebhetri, i-voltage yebhetri iguqukayo kunye notshintsho lwangaphakathi. Ingakumbi xa ibhetri iyaluphala, i-voltage yayo yaso ihluka kakhulu. Umzekelo, i-windows ye-termal yebhetri ye-12 v ukuya kwi-10 v ukuya kwi-16 v.
I-4. Kwindlela ephakathi nenkulu ye-photolvoltaic ye-photoltaic ye-photoltaic, ukukhutshwa kwamandla e-Inverter kufanele ukuba ibe liza i-sene ye-sine engatyanga kancinci. Oku kungenxa yokuba kwiinkqubo eziphakathi nekhulu, ukuba kusetyenziswa amandla esikwere, ukukhutshwa kuya kuba nezinto ezilinganayo, kwaye i-harmonics ephezulu iya kuvelisa ilahleko eyongezelelweyo. Iinkqubo zokuveliswa kwamandla ePhotvoltaic zilayishwa ngonxibelelwano okanye izixhobo zesixhobo. Izixhobo zineemfuno eziphezulu kumgangatho wegridi yamandla. Xa iinkqubo zokuveliswa kwe-phyvoltaic kunye ne-Prevvoltaic ye-Prevvoltaic ye-Prevloltaic ixhunyiwe kwigridi, ukwenzela ukuthintela ukungcoliseka kwamandla kwigridi yoluntu, i-inverter nayo iyacelwa nokuba ikhuphe i-sne yangoku i-sne yangoku.
I-Inverter iguqula ikhoyo yangoku kwi-ternating okwangoku. Ukuba i-voltage ekhoyo ngoku iphantsi, ikhutshelwe yinguqu yangoku iguquli ukufumana i-voltage eqhelekileyo kunye nefreyimu. I-Abverter enkulu, ngenxa yevolthi ye-DC ephezulu ye-DC, iziphumo ze-AC ngokubanzi azidingi iguquli ukukhulisa i-voltage ukuya kwi-220v. Kwiphepha elingaphakathi kunye namancinci, i-DC Voltage iphantsi, njenge-12v, kwi-24v, isiphaluka esikhulayo kufuneka siyilwe. I-Andver-Any-Assers encinci iquka ngokubanzi ibandakanya imijikelezi ye-Inverter ye-Inverter, i-Inver-egcwele i-Inverter egcwele i-Inverter kunye nesangqa esiphezulu se-Invest. I-push-tsala iskengi etsala iplagi yokungathathi hlangothi kwi-sporramer yokunyusa amandla, kwaye iityhubhu zangaphantsi zinokuqhakamshelana nesekethe, ngenxa yokuba i-Destimer iqhagamshele kwisekethe, inokuthi inciphise ukuthembeka kwesekethe. Ukungancedi kakuhle kukuba ukusetyenziswa kwe-translormer kuphantsi kwaye amandla okuqhuba imithwalo engasebenziyo ihlwempu.
Itekethe ye-Inidge egcweleyo iphela iyongeza iintsika zesekethe yokutsala. I-trivement yamandla ilungelelanisa i-pulse yobubanzi, kunye nexabiso elisebenzayo lemigaqo yevolthi yemveliso etshintsha ngokufanelekileyo. Kungenxa yokuba isekethe inelogo yokukhululeka, nkqu nemithwalo engaphelelanga, i-voltage ye-voltage yemveliso ayiyi kugwetywa. Ukungancedisi kwesi siphaluka kukuba amandla eenqobo ezizomileyo kunye nezingaphantsi akabelani emhlabeni, ngoko ke isiphaluka esinikezelweyo okanye ubonelelo lwamandla oluninzi kufuneka lusetyenziswe. Ukongeza, ukwenzela ukuthintela ukubaluleka kwebhulorho ephezulu nezantsi, kufuneka kwenziwe ukuba kucinywe, oko kukuthi, ixesha elifileyo limele libekwe, kwaye isakhiwo sesekethe sinzima.
Iziphumo zesekethe yokutyhala i-type-tsuss kunye nesekethe egcweleyo kufuneka yongeze i-spireformer yenyathelo. Ngenxa yokuba i-shriformer yenyathelo inkulu kakhulu ibukhulu, iphantsi ngokusebenza kakuhle, kwaye ibiza kakhulu, ngokuphuhliswa kwamandla e-Electronics kunye neTekhnoloji ye-Microelectinics, i-Microelectinics, i-Free-Right-up an Andverter ephezulu yamandla. Inqanaba langaphambili lesekethe yale sekethe ye-inverter yamkela isakhiwo se-ping-super, kodwa isantya esisebenzayo singaphezulu kwe-20khz. Inguqulelo yokuphucula i-andtic yamkela i-gore-free right ye-rightic ye-rightic ye-high ye-goretic, ngoko incinci ngokobukhulu kunye nokukhanya kubunzima. Emva kokungaphaya kwesikhuselo esiphakamileyo, iguqulwa ibe yi-depriency ephezulu ngokuhambahamba rhoqo, kwaye emva koko i-Wightied Right ePhakamileyo yeFostitied Right, kwaye ihlawulwe kwisekethe ye-inverter ye-inverter ye-inverter ejikelezayo.
Ngalo sakhiwo sesekethe, amandla e-Inverters aphuculwe kakhulu, ukuphulukana ne-inir ye-inverter kuyancitshiswa ngokulandelelana, kwaye ukusebenza kakuhle kuphuculwe. Ukungancedisi kwisekethe kukuba isekethe inzima kwaye ukuthembeka kungaphantsi kweziphaluka ezimbini ezingasentla.
Ukulawulwa kwesekethe ye-inverter
Ezona zisekethe ziphambili zala manzi akhankanywe apha ngasentla zonke kufuneka zifikelele kwisekethe yokulawula. Ngokubanzi, zimbini iindlela zokulawula: amaza asisikwene kunye namaza athembekileyo kwaye abuthathaka. Isekethe ye-Inverter Screen Screen kunye nemveliso yesikwere ilula, iphantsi ngexabiso, kodwa iphantsi ngokusebenza kakuhle kunye nezinto ezinkulu kwizinto ezilinganayo. . Imveliso ye-SIne Wave yinto yophuhliso ye-ineverters. Ngokuphuhliswa kwetekhnoloji ye-microhelectronics, i-microprocessor enemisebenzi ye-PWM sele iphume. Ke ngoko, itekhnoloji ye-inverter yemveliso ye-Sine Wave iye yakhula.
I-1. I-Inverters kunye nemveliso ye-Square WaveS ezisebenzisa iisekethe ezihlanganisiweyo ze-pulse-bority, ezinje nge-SG 3 525, tl 494 njalo njalo. Ukuziqhelanisa kungqineke ukuba ukusetyenziswa kweesekethe ezihlanganisiweyo ze-SG3525 nokusetyenziswa kwamandla e-FET njengokutshintsha kwamandla amandla anokufumana ukusebenza kakuhle kunye namaxabiso amaxabiso. Kuba i-SG3525 inamandla okuqhuba ngokuthe ngqo amandla e-DET i-FETS i-FET kwaye inomthombo wangaphakathi kunye nokusebenza kwe-Amplimier kunye noMsebenzi wokukhusela i-Ampsgoltime kunye nesekethe yokukhusela i-Devergoltic, ke i-PAIPHORT ilula kakhulu.
2. I-Inverter I-Inverter Copporting Imveliso ye-Sine Wave, i-Inverter ye-Inverter enemveliso ye-SIne Wave inokulawulwa ngumnxibelelanisi we-Intel, kwaye iveliswe yinkampani ye-Inter. I-MP 16 kunye ne-PI C 16 C iveliswe yinkampani ye-MIP ye-MIP, njl. Njl. Ngexesha elifileyo, sebenzisa iNkampani ye-Intel 80 c 196 MC ukuze uqonde isiphaluka se-SIne Wave, 80 c 196 MC ukugqiba isizukulwana se-Sine Wave, kwaye ufumane i-Ac Retiege Flomge yokufezekisa ukulungiswa kweevolthi.
Ukukhetha izixhobo zamandla kwisekethe ephambili ye-inverter
Ukukhetha amacandelo ombane aphambilii-inverteribaluleke kakhulu. Okwangoku, ezona zinto zisetyenziswayo zisebenzisa i-Darlington Sundston Arpastors (BJT), uMoyeni weNdawo yokuSebenzisa (I-MOS-F Et), abaThengisi beSango (IGB). T) kunye ne-quidrikyuli (GTO), njl.njl. Oku kungenxa yokuba ukuxhathiswa kwe-Mos-State ye-FET ngokunyuka kwe-voltage, kunye ne-IG BT ikwiinkqubo eziphakathi ze-PREAMSE, ngaphezulu kwe-100 ye-100 ye-KVAER, i-GTOS isetyenziswa njengamacandelo amandla.
IXESHA LOKUQALA: I-OCT-21 ukuya kwi-2121
