Emqhudelwaneni oshubile we "grid parity" embonini ye-photovoltaic, ukuthuthukiswa kwezindleko zawo wonke ama-kilowatt-hora kagesi kuhlobene nokuncintisana okuyinhloko kwamabhizinisi. Njengemishini ebalulekile ekukhiqizeni amamojula weseli yelanga, ukunemba kwesikhulumi esihambayo somshini wokushisela intambo ye-photovoltaic kuthinta ngqo ikhwalithi yokushisela nokusebenza kahle kokukhiqiza. Inkundla yegwadle enyakazayo enikelwe emishinini yokushisela intambo ye-photovoltaic, enokuqina kwayo kobukhulu bokugcina okungu-0.5μm/ngonyaka, ihlinzeka ngosekelo lobuchwepheshe lokunciphisa izindleko nge-kilowatt-hora ukusuka kubukhulu obuningi. .
Ukuzinza okuphezulu kuqinisekisa ukunemba kwe-welding futhi kunciphisa imfucuza yezinto ezibonakalayo
Ngesikhathi senqubo yokushisela izintambo zamaseli e-photovoltaic, ukuphambuka endaweni yokushisela kungaholela ekuxhumekeni okungalungile kwamaseli, ngaleyo ndlela kuthinte ukusebenza kahle kokukhiqizwa kwamandla kwamamojula ngisho nokukhiqiza imikhiqizo enesici. Inkundla yokunyakaza yendabuko ijwayele ukuwohloka kobukhulu ngenxa yezici ezifana noshintsho lokushisa kwemvelo nokudlidliza komshini, okuholela ekuphambukeni endaweni yokushisela. I-coefficient yokunwetshwa okushisayo kwenkundla yezemidlalo ye-granite kuphela (4-8) ×10⁻⁶/℃. Kuhlanganiswe nesakhiwo sayo sangaphakathi esiminyene nesifanayo, ukuzinza kwe-dimensional ka-0.5μm/ngonyaka kungafinyelelwa. .
Ukuthatha umugqa wokukhiqiza wemojula ye-photovoltaic ye-1GW njengesibonelo, uma isiteji sokunyakaza esivamile samukelwa, ukuchezuka kwesikhundla sokushisela okubangelwa ukuguqulwa kwe-dimensional kudlula u-0.1mm, okungabangela izinga lokukhubazeka kokushisela kwamaseli elanga likhuphukele ku-3%. Uma usebenzisa amapulatifomu ezemidlalo egwadle, izinga lesici sokushisela lingalawulwa ngaphakathi kuka-0.5%. Kukho konke ukuncishiswa okungu-1% kwesilinganiso sokukhubazeka, amaseli ebhethri anenani elingaphezu kwesigidi seyuan angalondolozwa unyaka ngamunye, kwehlise ngokuqondile izindleko zokukhiqiza zezingxenye futhi kubekwe isisekelo sokwehla kwezindleko nge-kilowatt-hora ngayinye. .
Yehlisa imvamisa yokugcinwa kwemishini futhi uthuthukise ukusebenza kahle kokukhiqiza
Isiteji esinyakazayo esinokuzinza kwe-dimensional okungesihle sizobangela ukuguga okusheshisiwe kwezingxenye zokudlulisela kanye nokuncipha kokunemba kokuma ngenxa yokuguquguquka ngesikhathi sokusetshenziswa kwesikhathi eside, futhi ngaleyo ndlela kudinga ukulinganisa nokugcinwa kwemishini okuvamile. Amapulatifomu ezemidlalo e-Granite, ngokuzinza kwawo okuvelele, anganciphisa ngempumelelo ukuvela kwezinkinga ezinjalo. .
Ngenxa yokuhluka kwayo okuncanyana okungu-0.5μm ngonyaka, izinga lokuguga lezingxenye ezibalulekile ezifana nendlela yokudlulisela kanye nenzwa yokuma yomshini wokushisela izintambo zehla kakhulu. Ngokusho kwedatha yangempela yokulinganisa yebhizinisi elithile lokukhiqiza i-photovoltaic, ngemva kokwamukela isiteji sokunyakaza se-granite, umjikelezo wokunakekelwa komshini wokushisela wezintambo unwetshiwe kusukela kanye ngenyanga kuya kanye ngekota, futhi isikhathi esisodwa sokulondoloza sifinyeziwe kusukela emahoreni angu-8 kuya emahoreni angu-3. Ukwehliswa kwemvamisa yokugcinwa kwemishini kusho ukusebenza kahle okuphezulu kokukhiqiza kanye nezindleko eziphansi zokusebenza nokugcinwa kwemishini. Ngokusekelwe emgqeni wokukhiqiza onamandla wonyaka we-500MW, ingakhuphula isikhathi sokukhiqiza esisebenzayo cishe ngamahora angu-200 unyaka ngamunye, ikhiqize amamojula amaningi we-photovoltaic abiza ngaphezu kwe-5 million yuan, futhi inciphise kakhulu izindleko nge-kilowatt-hora ngayinye. .
Nweba impilo yesevisi yezisetshenziswa futhi wehlise izindleko zokutshala imali
Izindleko zokutshala izimali zemishini yokukhiqiza i-photovoltaic ziphakeme, futhi impilo yesevisi yemishini ithinta ngokuqondile ukubuyisela ekutshalweni kwezimali kwamabhizinisi. Ngenxa yezinguquko zesikhathi eside zobukhulu kanye nokonakala kwesakhiwo, izinkundla ezijwayelekile ezinyakazayo zivame ukwehluleka ukuhlangabezana nezidingo zokukhiqiza ezinembayo ngaphezulu kweminyaka emihlanu. Ngenxa yalokho, amabhizinisi kufanele ashintshe okokusebenza kusenesikhathi, okwandisa ingcindezi yokutshalwa kwempahla engashintshi. .
Amapulatifomu ezemidlalo e-Granite, anezici zawo ezizinzile zomzimba namakhemikhali, angagcina ukunemba okuphezulu ngesikhathi sokusetshenziswa isikhathi eside futhi andise ngempumelelo impilo yonke yesevisi yomshini wokushisela izintambo. Idatha evela kumkhiqizi wemishini ethile ye-photovoltaic ibonisa ukuthi umshini wokushisela izintambo ofakwe isiteji sokunyakaza se-granite usengagcina ukunemba kokuma kokushisela ngaphakathi kuka-±0.1mm ngemva kokusetshenziswa okuqhubekayo iminyaka engu-8, uhlangabezana nezidingo zokukhiqiza zezingxenye ezisebenza kahle kakhulu. Ngokuphambene, amadivayisi asebenzisa amapulatifomu anyakazayo ajwayelekile adinga ukushintshwa izingxenye zawo eziyinhloko noma wonke umshini uthuthukiswe ngemva kweminyaka emihlanu. Ukwelulwa kwesikhathi senkonzo yezinto zokusebenza kuvumela izindleko zokutshalwa kwezimali zempahla egxilile zamabhizinisi ukuba zabiwe isikhathi eside, kuphinde kunciphise ingxenye yokwehla kwenani lempahla ezindlekweni ngehora le-kilowatt. .
Ukwenza lula ukukhiqizwa kwezingxenye ezisebenzayo futhi kwandiswe imali yokuphehla amandla
Ukuzinza kobukhulu obungu-0.5μm/ngonyaka kunikeza isiqinisekiso somshini wokushisela intambo ye-photovoltaic ukuze uzuze ukushisela okunembayo okuphezulu, okuvumela amabhizinisi ukuthi akhiqize amamojula e-photovoltaic ngokusebenza kahle okuphezulu. Ezicelweni ezisebenzayo zeziteshi zikagesi, izingxenye ezisebenza kahle kakhulu zingafinyelela umthamo ophezulu wokuphehla ugesi kanye nezinga eliphansi lokuncipha, ngaleyo ndlela kuthuthukiswe yonke imali engenayo yokuphehlwa kukagesi esiteshini sikagesi. .
Isibonelo, amamojula anengilazi ekabili anezinhlangothi ezimbili ane-welding enembayo ephezulu angakhuphula ukusebenza kahle kokukhiqizwa kwamandla ngo-3% kuya ku-5% uma kuqhathaniswa namamojula ajwayelekile. Thatha i-100MW photovoltaic power station njengesibonelo. Ngokusebenzisa izingxenye ezisebenza kahle kakhulu, ingakwazi ukukhiqiza ugesi ongeziwe ongama-kilowatt-awa ayizigidi ezi-3 kuya kwezi-5 ngonyaka. Ukwenyuka kwemali etholwayo yokuphehlwa kukagesi kusho ukwehla okulinganiselwe kwezindleko nge-kilowatt-hora, okuqhubeka kuthuthukisa umnotho kanye nokuncintisana kweziteshi zikagesi ze-photovoltaic. .
Isiteji esinyakazayo se-granite esinikezelwe emishinini yokushisela intambo ye-photovoltaic, enokuqina kobukhulu obungu-0.5μm/ngonyaka njengenzuzo yayo eyinhloko, inciphisa ngokuphelele izindleko zokukhiqiza amamojula we-photovoltaic kanye nezindleko zehora ngalinye nge-kilowatt yeziteshi zamandla ngokusebenzisa izindlela eziningi ezinjengokuqinisekisa ukunemba kokushisela, ukunciphisa ukugcinwa kwezinto zokusebenza, ukunweba ukugcinwa kwezinto zokusebenza, ukunweba ukusebenza kwemishini. Inikeza ukwesekwa okuqinile kwezobuchwepheshe embonini ye-photovoltaic ukuze kuzuzwe "ukulingana kwegridi" kanye nentuthuko eqhubekayo.
