Umgomo weSolar Photovoltaic Power Generation ubuchwepheshe obuguqula ngqo amandla okukhanya abe amandla kagesi ngokusebenzisa umphumela we-photovoltaic wesikhombimsebenzisi se-semiconductor. Ingxenye esemqoka yalobu buchwepheshe yingqamuzana elanga. Amangqamuzana elanga ahlanganisiwe futhi avikelwe ngochungechunge lokwenza imodyuli enkulu ye-solar ye-solar abese ehlanganiswe nesilawuli samandla noma okufanayo ukwakha i-Photovoltaic amandla okuphehla amandla. Yonke inqubo ibizwa ngokuthi uhlelo lokuphehla lwamandla we-Photovoltaic. Uhlelo lwe-Photovoltaic Power Generation System luqukethe ama-solar cell arrays, amaphakethe webhethri, ukushaja kanye nokulawulwa kokukhipha, ama-solar photovoltaic ama-inverters, amabhokisi ahlanganisiwe neminye imishini.
Kungani usebenzise i-inverter ku-solar photovoltaic amandla esizukulwaneni sokwenza amandla?
I-inverter iyithuluzi eliguqula liqonde ngqo ekuguqukeni kwamanje. Amaseli elanga azokhiqiza amandla we-DC elangeni, namandla e-DC agcinwe ebhethri nawo amandla we-DC. Kodwa-ke, uhlelo lwe-DC Power Supply lunokulinganiselwa okukhulu. Imithwalo ye-AC enjengamalambu we-fluorescent, ama-TV, ama-esiqandisi, kanye nabalandeli bakagesi empilweni yansuku zonke abanakuxhaswa ngamandla we-DC. Nge-Photovoltaic Power Generation ukuze isetshenziswe kabanzi empilweni yethu yansuku zonke, ama-inverters angaguqula amanje aqondile ekuguqukekeni kwamanje asemqoka.
Njengengxenye ebalulekile ye-Photovoltaic Power Generation, i-inverter ye-Photovoltaic isetshenziselwa ikakhulukazi ukuguqula amanje ekhiqizwe njengamanje ekhiqizwe amamojula we-Photovoltaic ukushintshana kwamanje. I-Inverter ayigcini nje ngokusebenza kwe-DC-AC ukuguqulwa, kepha futhi inomsebenzi wokukhulisa ukusebenza kweseli yelanga kanye nomsebenzi wokuvikelwa kwamaphutha esistimu. Okulandelayo ukwethulwa okufushane kokusebenza okuzenzakalelayo nemisebenzi ye-shutdown ye-inverter ye-Photovoltaic kanye nomsebenzi wokulawula wamandla wokulandela amandla.
1. Umsebenzi wokulawula amandla aphezulu
Ukukhishwa kwemodyuli ye-solar cell kuyahlukahluka ngokuqina kwemisebe yelanga kanye nokushisa kwemodyuli yelanga uqobo (lokushisa chip). Ngaphezu kwalokho, njengoba imodyuli ye-solar cell inesimo sokuthi ivola lincipha njengokunyuka kwamanje, kunephuzu elisebenzayo lapho amandla aphezulu angatholakala khona. Ukuqina kwemisebe yelanga kuyashintsha, futhi kusobala ukuthi iphuzu lokusebenza kahle liyashintsha. Okuhlobene nalezi zinguquko, indawo yokusebenza yemodyuli yelanga ihlala endaweni ephezulu yamandla, futhi uhlelo luhlala luthola okuphezulu kokukhipha kwamandla kusuka kumodyuli ye-Solar Cell. Lokhu kulawula kungukulawulwa kwamandla okulandela amandla aphezulu. Isici esikhulu kunazo zonke sama-Inverterers for Solar Power Systems ukuthi afaka phakathi umsebenzi wokulandela kwamaphoyinti aphezulu (MPPT).
2. Ukusebenza okuzenzakalelayo nomsebenzi wokumisa
Ngemuva kokuphuma kwelanga ekuseni, ubukhulu bemisebe yelanga bukhuphuka kancane kancane, futhi ukuphuma kweseli lelanga nakho kuyanda. Lapho amandla okukhipha afunwa yi-inverter afinyelelwa, i-inverter iqala ukusebenza ngokuzenzakalelayo. Ngemuva kokungena ekusebenzeni, i-inverter izobheka umphumela wemodyuli yelanga ngaso sonke isikhathi. Uma nje amandla okukhipha emodyuli yelanga elanga likhulu kunamandla okukhishwa adingekayo kwi-inverter ukuthi isebenze, i-inverter izoqhubeka nokugijima; Izoma kuze kube yilapho ilanga, noma linamafu futhi lina. I-inverter nayo ingasebenza. Lapho umphumela wemodyuli ye-solar cell eba mncane futhi umphumela we-inverter useduze no-0, i-inverter izokwakha isimo sokulinda.
Ngaphezu kwemisebenzi emibili echazwe ngenhla, i-Photovoltaic Inverter nayo inomsebenzi wokuvimbela ukusebenza okuzimele (kohlelo oluxhunywe ngegridi), umsebenzi oxhumekile we-grid (ohlelweni oluxhunywe yi-grid) , nomsebenzi wokutholwa kwesisekelo se-DC (ngezinhlelo ezixhunywe yigridi) neminye imisebenzi. Ohlelweni lwamandla e-solar Generation System, ukusebenza kahle kwe-Inverter kuyinto ebalulekile enquma umthamo weseli yelanga kanye nomthamo webhethri.
