Ngaphambi kokunyuka komzi-mveliso wefotovoltaic, i-inverter okanye itekhnoloji ye-inverter yayisetyenziswa ikakhulu kumashishini anjengokuhamba kukaloliwe kunye nokunikezelwa kwamandla. Emva kokunyuka komzi-mveliso wefotovoltaic, i-Inittervoltaic Inverter iye yaba zizixhobo eziphambili kwinkqubo entsha yokuvelisa amandla, kwaye uqhelene nomntu wonke. Ngakumbi kumazwe aphuhlileyo eYurophu naseMelika, ngenxa yembono ethandwayo yokulondolozwa kwamandla kunye nokukhuselwa kwendalo, imakethi yefotovoltaic iphuhliswe ngaphambili, ingakumbi kuphuculo olukhawulezayo lweenkqubo zefotovoltaic yekhaya. Kumazwe amaninzi, amantshontsho asekhaya asetyenziswa njengezixhobo zekhaya, kwaye izinga lokungena liphezulu.
I-Initvoltaic i-Initter iguqula i-Free Rived eveliswe ziimodyuli zefotovoltaic kwindawo yokutshintsha kwangoku kwaye iyoyike kwigridi. Intsebenzo kunye nokuthembeka kwe-ingenayo ichonge umgangatho wamandla kunye nokusebenza kwamandla ukusebenza kwamandla. Ke ngoko, i-Initvoltaic i-Inverter ikwi-core yayo yonke inkqubo yokuvelisa amandla ePhekimestiki. inqanaba.
Phakathi kwazo, iAged-Cards-Maners isebenzisa isabelo esiphambili sentengiso kuwo onke amanqanaba, kwaye kukwasisiqalo sophuhliso lwazo zonke iitekhnoloji ze-inverter. Xa kuthelekiswa nezinye iintlobo zamantshontsho, iigreyithi zegridi ezixhunyiweyo zilula kwitekhnoloji, egxile kwiPhotvoltaic igalelo kunye nemveliso yeGridi. Ikhuselekile, inokuthenjwa, ngokufanelekileyo, kwaye inamandla ekuphumezeni iphezulu ibe yeyona nto ibalulekileyo kwi-iniverters enjalo. Izikhombisi zobugcisa. Kwiimeko zobugcisa zokugqobhozwa kwe-fotovoltaic-uqhagamshelo lwe-fotovoltaic eqhagamshelwe kumazwe ahlukeneyo, la manqaku angentla abe ngamanqaku aqhelekileyo aqhelekileyo omgangatho, kunjalo, iinkcukacha zeparameter zahlukile. Kwii-Averter-qhos, zonke iimfuno zobugcisa zigxile ekufezekiseni iimfuno zegridi yeenkqubo ezisasaziweyo, kwaye iimfuno ezingakumbi zivela kwiimfuno zegridi yegridi, oko kukuthi, iimfuno eziphambili. Njengombane wevolthi, imigaqo-nkqubo yokuhamba rhoqo, iimfuno zomgangatho wamandla, ukhuseleko, iimfuno zolawulo xa kusenzeka impazamo. Kwaye indlela yokuqhagamshela kwigridi, yeyiphi i-voltage inqanaba lamandla amandla okubandakanywa, njl. Kwaye ukusuka kwimbono yobugcisa, ingongoma ebaluleke kakhulu kukuba i-Inverter-qho exhunyiwe yi "Grid-exhunyiwe i-Grid", oko kukuthi, kuvelisa amandla xa ihlangabezana neemeko ezixhunyiweyo. Kwimicimbi yolawulo lwamandla kwinkqubo yefotovoltaic, ngoko ke ilula. Ilula njengemodeli yeshishini yombane. Ngokutsho kwezibalo zamanye amazwe, zingaphezulu kwe-90% yeenkqubo zefotovoltaic eziye zakhiwa kwaye zisebenza ziinkqubo ezixhunyiweyo zefotovoltaic, kunye ne-interdited exwilwe i-grid.
Iklasi ye-intervers ejongene ne-grid-qho exutywe yi-inir-grid ingaphandle. I-inverter engaphandle ye-Grid ithetha ukuba i-Initverter ye-Inverter ayixhunyiwe kwigridi, kodwa iqhagamshelwe kumthwalo, oqhuba ngqo umthwalo wokubonelela ngamandla. Kukho izicelo ezimbalwa zamantshontsho egridi, ikakhulu kwezinye iindawo ezikude, apho iimeko ezixineneyo zegridi azifumaneki, iimeko ezixineneyo zihluphekile, okanye kukho imfuneko yokuziphambuka, inkqubo yokuzilolonga igxininisa "ukuzibandakanya kunye nokuzisebenzisa". . i-interver. Kumele kutshiwo ukuba inkqubo enamangangayi-gava e-Off-Grid, iiPholethisi, iiBeteries, imithwalo kunye nezinye izixhobo ze-micro-rid. Inqaku kuphela kukuba inkqubo ingaxhunyiwe kwigridi.
Inyaniso,I-evertersisiseko sokuphuhliswa kwe-interters yeBhidirectial. I-Bidirecal Anthers idibanisa iimpawu zobugcisa zamantshontsho amanqam aqhagamshelwe kwigridi kunye ne-ever-rives, kwaye zisetyenziswa kwiinethiwekhi zoncedo lwamandla endawo okanye iinkqubo zokuvelisa amandla. Xa isetyenziswa ngokuhambelana negridi yamandla. Nangona zingabi zininzi izicelo zolu hlobo okwangoku, kuba olu hlobo lwenkqubo luyindlela yokuphuhliswa kwe-microgrid, kuhambelana nendlela yokusebenza kwamandla esasazwe kwixesha elizayo. kunye nezicelo ze-microgrid ezizayo. Ngapha koko, kwamanye amazwe kunye neemarike apho iifotovoltics zikhula ngokukhawuleza kwaye zivuthi, ukusetyenziswa kwee-microgrids kumakhaya kunye neendawo ezincinci sele ziqalile ukukhula kancinci. Kwangelo xesha, urhulumente wengingqi ukhuthaza ukuphuculwa kwamandla endawo, ukugcinwa nokusetyenziswa kwenethiwekhi ngamakhaya, ukubeka kwindawo entsha yokuzivelisa, kunye nenxalenye engonelanga kwigridi yamandla. Ke ngoko, i-bidirectialter ifuna ukuqwalasela imisebenzi yolawulo ngakumbi kunye nemisebenzi yolawulo lwamandla, njengokuhlawuliswa kwetekisi kunye nokulawula iiqhinga, kunye neendlela zokusebenza zegridi, kunye neendlela zokubonelela ngamandla e-Grid. Zonke izinto zangaphakathi, i-bidirectialter idlala imisebenzi ebaluleke ngakumbi yolawulo kunye nolawulo evela kwimbono yonke, endaweni yokuba iqwalasele kuphela iimfuno zegridi okanye umthwalo.
Njengomnye wendlela yophuhliso yegridi yamandla, ukuvelisa amandla endawo, ukuhanjiswa kunye nenethiwekhi yokusetyenziswa kwamandla eyakhiwe kunye neyona ndlela iphambili yophuhliso lwe-microgrid kwixesha elizayo. Kule ndlela, iMicrogrid yasekhaya iya kwenza ubudlelwane obusebenzayo kunye negridi enkulu, kwaye i-microgrid ingasasebenzi ngokusondeleyo kwigridi enkulu, kodwa iya kusebenza ngakumbi ngokuzimeleyo, oko kukwimo yesiqithi. Ukuze uhlangabezane noKhuseleko loMmandla kwaye unike indawo yokuqala yokusebenzisa amandla athembekileyo, imowudi yokusebenza exhunyiweyo ye-grid yenziwa kuphela xa amandla endawo eninzi okanye kufuneka athathwe kwigridi yamandla angaphandle. Okwangoku, ngenxa yeemeko zokuphathwa kweetekhnoloji ezahlukeneyo kunye nemigaqo-nkqubo, i-microgrids ayifakwanga kwinqanaba elikhulu, kwaye kuphela inani elincinci leeprojekthi ezisebenzayo, kwaye uninzi lwezi projekthi ziqhagamshelwe kwigridi. I-Microgrid Antter idibanisa amanqaku obuchwephesha be-bidirectial, idlala umsebenzi obalulekileyo wegridi. Lulawulo oluqhelekileyo kunye nomatshini ohlanganisiweyo ohlanganisiweyo odibanisa i-ineverter, ulawulo kunye nolawulo. Ixhomekeke kulawulo lwamandla asekuhlaleni, ulawulo lomthwalo, ulawulo lwebhetri, i-inger, ukhusela kunye neminye imisebenzi. Iya kuwugqiba umsebenzi wolawulo kuyo yonke i-microgrid kunye nenkqubo yolawulo lwamandla e-Microgiririd (i-MGEMS), kwaye iya kuba zizixhobo eziphambili zokwakha inkqubo ye-microgrid. Xa kuthelekiswa ne-inverter ye-Inverter yokuqala yophuhliso lwetekhnoloji ye-inverter, yahlula-hlula umsebenzi ococekileyo wase-Inverter kwaye yawuphatha umsebenzi wolawulo kunye nolawulo, ukusombulula iingxaki ukusuka kwinqanaba lenkqubo. I-inverter yogcino lwamandla ibonelela nge-bidirectional isikhuselo, ukuguqulwa okwangoku, kunye nokutshaja kwebhetri kunye nokuyeka. Inkqubo yolawulo lwe microgrid ilawula yonke i-microgrid. Abanxibelelanisi A, B, no-C balawulwa yinkqubo yolawulo lwe-Microgrid kwaye banokusebenza kwiziqithi ezikwanti. Sika imithwalo engeyiyo egxekayo ngokokubonelela ngamandla amaxesha ngamaxesha ukugcina uzinzo lwe-microgrid kunye nokusebenza okukhuselekileyo kwemithwalo ebalulekileyo.
