Izixhumi ze-PV DC Akufanele Zinganakwa Esiteshini Solar Photovoltaic

Ngokusekelwa kwezinqubomgomo ezihlukahlukene, ukwakhiwa kwezitshalo zamandla e-photovoltaic sekuhamba phambili, futhi izindaba zokuphepha zihamba phambili.Umbiko ukhombisa ukuthi ekulahlekeni kwemali yokuphehla ugesi okudalwe ingozi yokwehluleka kobuchwepheshe be-TOP20 besiteshi sikagesi, ukulimala kanye nokushiswa kwemishini kagesi.Isixhumi se-PV DCikleliswe endaweni yesibili.

Esimweni sokufeza "injongo ye-carbon dual", kulinganiselwa ukuthi eminyakeni emihlanu ezayo, umthamo omusha wonyaka wezwe lami we-photovoltaic ofakiwe uzofinyelela ku-62 kuya ku-68 GW, futhi umthamo ofakiwe waseChina ofakiwe weziteshi zamandla we-photovoltaic uzofinyelela ku-561 GW 2025.

Kuyaqapheleka ukuthi kungakhathaliseki ukuthi isiteshi samandla esingaphansi komhlaba noma isiteshi samandla esabalalisiwe, umthamo ofakiwe we-photovoltaic uzongena esigabeni sokukhula okukhulu, kodwa kunezinkinga eziningi zokuphepha eziza nayo, eziye zadonsa ukunaka. wemboni.

Ukuphepha kuwumgogodla wezitshalo zamandla e-photovoltaic, futhi kuyisisekelo sokuthola imbuyiselo ekutshalweni kwezimali.Kungakhathaliseki ukuthi yiziphi izigcawu zezitshalo zamandla e-photovoltaic emhlabathini, entabeni, ophahleni, njll., ukuphepha kuyindaba yesimiso.

Izingozi Ezintathu Ezifihliwe Ezitshalweni Zamandla E-Photovoltaic

Kunezizathu ezintathu eziyinhloko zenkinga yengozi yesiteshi sikagesi se-photovoltaic:

Okokuqala, isixhumi sephaneli yelanga ye-PV DC, evame ukubizwa ngokuthi isixhumi se-MC4.Lapho amandla ama-module e-PV eba mkhulu futhi ekhudlwana, amanje azokhula ngokufanele.Kulesi simo, isixhumi sephaneli yelanga sishisa kakhulu, okudala ingozi yomlilo.Ngakho-ke, isixhumi singelinye lamaphuzu avame ukuvutha kusixhumanisi esiseceleni se-DC semojula.

Okwesibili, ibhokisi lokuhlanganisa le-PV DC.Ebhokisini lokuhlanganisa le-DC, kunemigqa ehlelekile eminyene nezinto zikagesi, kanye nebhokisi lensimbi elivaliwe.Endaweni yesakhiwo esivaliwe, ukushisa kwezinto zikagesi kanye nezindawo zokuxhuma ebhokisini kuzoba phezulu, futhi akulula ukukhipha ukushisa.Endabeni yokusebenza isikhathi eside Ngaphansi kwezimo, izinkinga ezinjengokushisa nokukhubeka kwemishini kagesi zivame ukuba yingozi efihliwe yomlilo.

Okwesithathu, amakhebula aphakathi nendawo naphezulu.Eziteshini zikagesi, amasistimu kagesi kagesi aphakathi kuka-35 kV kanye namasistimu okukhulisa amandla kagesi aphezulu angu-110kV/220kV avamile.Izinga likagesi lemikhiqizo yamandla kagesi aphakathi nendawo naphezulu liphezulu uma kuqhathaniswa.Imikhiqizo yezisekeli zekhebula ijwayele ukukhishwa ingxenye kanye nezinkinga zokuwohloka.Ngakho-ke, lokhu futhi kuyi-photovoltaic Enye yezingozi ezifihliwe zezingozi zesiteshi samandla kagesi.

Ku-PV Power Station Top 20 Failure Technical, Isixhumi se-PV DC Sikleliswe Kwesibili

Kungabonakala ekuhlaziyweni kwezizathu ezintathu ezingenhla ukuthi izingozi zokuphepha ezingaba khona ezilethwa isixhumi se-PV DC azikwazi ukushaywa indiva!Uma kungenjalo, izingozi ezifana nomlilo wesixhumi, ukutubeka,Ibhokisi lokuhlangana le-PVukwehluleka, ukuvuza kwengxenye, nokwehluleka kwamandla kwezingxenye zeyunithi yezinhlamvu kuzokwenzeka kamuva.

Ngokombiko okhishwe ithimba lephrojekthi ye-“Solar Bankability” yohlelo lwe-European Union’s Horizon 2020, ukulimala kwesixhumi kanye nokutubeka kukleliswe endaweni yesibili ekulahlekelweni kwemali yokuphehla ugesi okubangelwa ubungozi bokwehluleka kwezobuchwepheshe kwesiteshi sikagesi TOP 20.

Ukulahlekelwa yimali engenayo yokuphehla amandla okubangelwa ingozi yokuhluleka kwesiteshi samandla e-photovoltaic esiphezulu se-20

Kungani Izixhumi ze-PV DC Zibaluleke Kangaka?

1. Sebenzisa ubuningi obuningi.Ezinhlelweni ze-photovoltaic, izixhumi zisetshenziswa kusuka kumaphaneli elanga, ama-inverters kusayithi lephrojekthi.Isistimu ye-photovoltaic engu-1MW cishe izosebenzisa amasethi angu-2000 kuya kwangu-3000 ezixhumi ze-PV DC ngokuya ngamandla amamojula asetshenzisiwe.

2. Ingozi engaba khona iphezulu.Isethi ngayinye yezixhumi ze-PV DC iqukethe izindawo eziyingozi ezingu-3 (izingxenye zokuxhuma, amatheminali amahle nezibi kanye nezingxenye zokuxhuma amakhebula), okusho ukuthi ohlelweni lwe-1MW, isixhumi singaletha amaphuzu engozi angu-6000 kuya kwangu-9000.Endabeni yokugeleza kwamanje, ukwanda kokumelana nokuxhumana kwesixhumi kuzoholela ekwandeni kokukhuphuka kwezinga lokushisa.Uma idlula izinga lokushisa elingamelana negobolondo lepulasitiki nezingxenye zensimbi, isixhumi kulula kakhulu ukuhluleka noma sibangele umlilo.

3. Ubunzima ekusebenzeni nasekulungisweni kwendawo.Iningi lesofthiwe yokuqapha ekhona ingaqapha kuphela izinga leyunithi yezinhlamvu.Kumaphutha athile kuyunithi yezinhlamvu, ukuxazulula inkinga kusayithi kusadingeka.Lokhu kusho ukuthi uma kunenkinga ngesixhumi se-MC4, kufanele sihlolwe ngamunye ngamunye.Eziteshini zamandla ezimboni nezentengiselwano (amapulangwe ensimbi yombala wensimbi), ukusebenza nokugcinwa kunzima kakhulu.Izisebenzi kudingeka zigibele ophahleni bese zivula mathupha ama-solar panel, adla isikhathi futhi akhathazayo.

4. Ukusetshenziswa kwamandla okukhulu.Isixhumi se-PV ngokwaso asikhiqizi amandla, singumthumeli wamandla.Enqubweni yokudluliselwa kwamandla, nakanjani kuzoba nokulahlekelwa.Uma kubalwa ngesilinganiso sokumelana nokuthintana kwezixhumi emakethe, isiteshi sikagesi esingu-50MW sizosebenzisa cishe izigidi ezi-2.12 kWh zikagesi ngenxa yezixhumi phakathi nesikhathi sokusebenza seminyaka engama-25.

Eqhutshwa izinqubomgomo kulo nyaka, ukwakhiwa kwezitshalo zamandla e-photovoltaic sekuhamba phambili, futhi umgomo wokungathathi hlangothi kwekhabhoni kanye ne-carbon peaking ingalindelwa, kodwa imfuneko yakho konke lokhu kufanele kube ukuphepha.Izinkampani zokuxhuma i-Photovoltaic nazo zidinga ukuphakamisa izixazululo ezintsha zenkinga yokuphepha, ukuze kuncishiswe ukuvela kwezingozi zokuphepha ngesikhathi sokusebenza kweziteshi zamandla e-photovoltaic, nokwenza umgwaqo wethu oya ekungathathi hlangothi kwekhabhoni uzinze futhi usebenze.
