Umgaqo wokuvelisa amandla elanga e-photovoltaic yiteknoloji eguqula ngokuthe ngqo amandla okukhanya kumandla ombane ngokusebenzisa umphumo we-photovoltaic we-interface ye-semiconductor.Inxalenye ephambili yale teknoloji yiseli yelanga.Iiseli zelanga zipakishwe kwaye zikhuselwe kwichungechunge ukuze zenze imodyuli yendawo enkulu yeseli yelanga kwaye emva koko idibaniswe nomlawuli wamandla okanye ezifana nokwenza isixhobo sokuvelisa amandla e-photovoltaic.Yonke le nkqubo ibizwa ngokuba yinkqubo yokuvelisa amandla e-photovoltaic.Inkqubo yokuvelisa amandla e-photovoltaic iqulethe iiseli zelanga, iipakethi zebhetri, izilawuli zokuhlawulisa kunye nokukhupha, i-solar photovoltaic inverters, iibhokisi zokudibanisa kunye nezinye izixhobo.
Kutheni usebenzisa i-inverter kwinkqubo yokuvelisa amandla elanga photovoltaic?
I-inverter sisixhobo esiguqula umsinga othe ngqo ube ngumsinga otshintshayo.Iiseli zeSolar ziya kuvelisa amandla eDC ekukhanyeni kwelanga, kwaye amandla eDC agcinwe ebhetrini nawo amandla eDC.Nangona kunjalo, inkqubo yonikezelo lwamandla yeDC inemida enkulu.Imithwalo ye-AC efana nezibane ze-fluorescent, iiTV, iifriji, kunye neefeni zombane kubomi bemihla ngemihla ayinakunikwa amandla amandla e-DC.Ukuze ukuveliswa kwamandla e-photovoltaic kusetyenziswe ngokubanzi kubomi bethu bemihla ngemihla, ii-inverters ezinokuguqula ngoku ngokuthe ngqo kwi-alternating current ziyimfuneko.
Njengenxalenye ebalulekileyo yokuvelisa amandla e-photovoltaic, i-photovoltaic inverter isetyenziselwa ukuguqula i-current ngqo eyenziwa yimodyuli ye-photovoltaic kwi-alternating current.I-inverter ayinayo kuphela umsebenzi wokuguqulwa kwe-DC-AC, kodwa inomsebenzi wokwandisa ukusebenza kweseli yelanga kunye nomsebenzi wokukhusela impazamo yenkqubo.Oku kulandelayo sisingeniso esifutshane ekusebenzeni ngokuzenzekelayo kunye nemisebenzi yokuvala i-photovoltaic inverter kunye nomsebenzi ophezulu wokulawula ukulandelela umbane.
1. Ubuninzi bomsebenzi wokulawula ukulandelwa kwamandla
Imveliso yemodyuli yeseli yelanga iyahluka kunye nobukhulu bemitha yelanga kunye nobushushu bemodyuli yeseli yelanga ngokwayo (ubushushu be-chip).Ukongezelela, ekubeni imodyuli yeseli yelanga inempawu yokuba i-voltage iyancipha njengoko inyuka ngoku, kukho indawo efanelekileyo yokusebenza apho amandla amaninzi angafumaneka.Ubunzulu bemitha yelanga buyatshintsha, kwaye ngokucacileyo eyona ndawo ilungileyo yokusebenza iyatshintsha.Ngokumalunga nolu tshintsho, indawo yokusebenza yemodyuli yeseli yelanga ihlala ikwindawo ephezulu yamandla, kwaye inkqubo ihlala ifumana amandla aphezulu aphuma kwimodyuli yeseli yelanga.Olu lawulo lolona lawulo lokulandelela amandla aphezulu.Olona phawu lukhulu lwee-inverters kwiinkqubo zamandla elanga kukuba lubandakanya umsebenzi wokulandelela ubungakanani bamandla obuninzi (MPPT).
2. Ukusebenza ngokuzenzekelayo kunye nomsebenzi wokuyeka
Emva kokuphuma kwelanga ekuseni, ubukhulu bemitha yelanga bukhula ngokuthe ngcembe, kwaye ukuveliswa kweseli yelanga kuyanda.Xa amandla aphumayo afunwa yi-inverter efikelelwe, i-inverter iqala ukusebenza ngokuzenzekelayo.Emva kokungena ekusebenzeni, i-inverter iya kubeka iliso kwimveliso yemodyuli yeseli yelanga lonke ixesha.Ngethuba nje amandla okuvelisa imodyuli yeseli yelanga inkulu kunamandla okuvelisa afunekayo ukuze i-inverter isebenze, i-inverter iya kuqhubeka isebenza;liya kuyeka de litshone ilanga, nokuba kukho amafu nemvula.I-inverter nayo inokusebenza.Xa imveliso yemodyuli yeseli yelanga iba yincinci kwaye imveliso ye-inverter isondele kwi-0, i-inverter iya kwenza i-standby state.
Ukongeza kwimisebenzi emibini echazwe ngasentla, i-photovoltaic inverter nayo inomsebenzi wokuthintela ukusebenza ngokuzimeleyo (kwi-grid-ixhunyiwe inkqubo), umsebenzi wokuhlengahlengiswa kwe-voltage ngokuzenzekelayo (kwinkqubo edibeneyo yegridi), umsebenzi wokufumanisa i-DC (kwinkqubo edibeneyo yegridi) , kunye nomsebenzi wokufumanisa i-DC (yeendlela ezidityanisiweyo zegridi) kunye neminye imisebenzi.Kwinkqubo yokuvelisa amandla elanga, ukusebenza kakuhle kwe-inverter yinto ebalulekileyo emisela umthamo weseli yelanga kunye nomthamo webhetri.
