Umgomo wokukhiqiza amandla elanga le-photovoltaic ubuchwepheshe obuguqula ngokuqondile amandla okukhanya abe amandla kagesi ngokusebenzisa umphumela we-photovoltaic we-interface ye-semiconductor.Ingxenye eyinhloko yalobu buchwepheshe yi-solar cell.Amaseli elanga ahlanganiswe futhi avikelwe ochungechungeni ukuze enze imojuli yeseli yelanga enkulu yendawo bese ehlanganiswa nesilawuli samandla noma okufanayo ukuze enze idivayisi yokukhiqiza amandla e-photovoltaic.Yonke inqubo ibizwa ngokuthi i-photovoltaic power generation system.Uhlelo lokukhiqiza amandla e-photovoltaic luqukethe ama-solar cell arrays, amaphakethe ebhethri, izilawuli zokushaja nokukhipha, ama-inverters e-solar photovoltaic, amabhokisi okuhlanganisa nezinye izinto zokusebenza.
Kungani usebenzise i-inverter ohlelweni lokukhiqiza amandla elanga le-photovoltaic?
I-inverter iyisisetshenziswa esiguqula isimanje esiqondile sibe samanje esishintshayo.Amaseli elanga azokhiqiza amandla e-DC ekukhanyeni kwelanga, futhi amandla e-DC agcinwe ebhethrini nawo angamandla e-DC.Kodwa-ke, uhlelo lokuhlinzeka ngogesi lwe-DC lunemikhawulo emikhulu.Imithwalo ye-AC efana namalambu e-fluorescent, ama-TV, iziqandisi, namafeni kagesi empilweni yansuku zonke ayikwazi ukunikwa amandla amandla e-DC.Ukuze ukukhiqizwa kwamandla e-photovoltaic kusetshenziswe kabanzi ekuphileni kwethu kwansuku zonke, ama-inverter angaguqula i-current eqondile abe ama-alternating current abalulekile.
Njengengxenye ebalulekile yokukhiqiza amandla e-photovoltaic, i-inverter ye-photovoltaic isetshenziselwa ikakhulukazi ukuguqula okwamanje okuqondile okukhiqizwa amamojula we-photovoltaic ku-alternating current.I-inverter ayinayo kuphela umsebenzi wokuguqulwa kwe-DC-AC, kodwa futhi inomsebenzi wokwandisa ukusebenza kweseli yelanga kanye nomsebenzi wokuvikela iphutha lesistimu.Okulandelayo isingeniso esifushane sokusebenza okuzenzakalelayo kanye nemisebenzi yokuvala i-photovoltaic inverter kanye nomsebenzi wokulawula ukulandelela amandla aphezulu.
1. Umsebenzi wokulawula ukulandelela amandla amakhulu
Ukukhishwa kwe-module ye-solar cell kuyahlukahluka ngokushuba kwemisebe yelanga kanye nokushisa kwe-module ye-solar cell ngokwayo (izinga lokushisa le-chip).Ngaphezu kwalokho, njengoba i-module ye-solar cell inesici sokuthi i-voltage iyancipha njengoba ukwanda kwamanje, kunephuzu lokusebenza elilungile lapho amandla aphezulu angatholakala khona.Ukuqina kwemisebe yelanga buyashintsha, futhi ngokusobala indawo yokusebenza efanelekile nayo iyashintsha.Ngokuphathelene nalezi zinguquko, indawo yokusebenza yemodyuli yeseli yelanga ihlale isendaweni yamandla aphezulu, futhi uhlelo luhlala luthola ukukhishwa kwamandla aphezulu kusuka kumojula yeseli yelanga.Lesi silawuli siwumkhawulo wokulawula ukulandelela amandla.Isici esikhulu kunazo zonke sama-inverters wezinhlelo zamandla elanga ukuthi afaka umsebenzi we-maximum power point tracking (MPPT).
2. Ukusebenza okuzenzakalelayo nomsebenzi wokumisa
Ngemva kokuphuma kwelanga ekuseni, ukuqina kwemisebe yelanga kukhula kancane kancane, futhi ukukhishwa kweseli yelanga nakho kuyanda.Lapho amandla okukhiphayo adingwa i-inverter efinyelelwa, i-inverter iqala ukusebenza ngokuzenzakalelayo.Ngemuva kokungena ekusebenzeni, i-inverter izoqapha ukuphuma kwemodyuli yeseli yelanga ngaso sonke isikhathi.Uma nje amandla okukhipha imojula yeseli yelanga makhulu kunamandla okukhipha adingekayo ukuze inverter isebenze, i-inverter izoqhubeka nokusebenza;iyoma kuze kushone ilanga, ngisho noma liguqubele futhi lina.I-inverter ingasebenza futhi.Lapho ukukhishwa kwemodyuli yeseli yelanga kuba kuncane futhi ukukhishwa kwe-inverter kusondele ku-0, i-inverter izokwakha isimo sokulinda.
Ngaphezu kwemisebenzi emibili echazwe ngenhla, isiguquli se-photovoltaic sinomsebenzi wokuvimbela ukusebenza okuzimele (kuhlelo oluxhunywe kugridi), umsebenzi wokulungisa ugesi ozenzakalelayo (owohlelo oluxhunywe kugridi), umsebenzi wokuthola i-DC (owohlelo oluxhunywe kugridi) , kanye nomsebenzi wokutholwa kwe-DC (kumasistimu axhunywe kugridi) neminye imisebenzi.Kuhlelo lokukhiqiza amandla elanga, ukusebenza kahle kwe-inverter kuyisici esibalulekile esinquma umthamo weseli yelanga kanye nomthamo webhethri.
