Izixhumi ze-PV DC azinakuhoywa kwisikhululo seSolar Photovoltaic

Ngokuxhaswa kwemigaqo-nkqubo eyahlukeneyo, ukwakhiwa kwezityalo zamandla e-photovoltaic zihamba ngokupheleleyo, kwaye imiba yokhuseleko iyona nto iphambili.Ingxelo ibonisa ukuba kwilahleko yengeniso yokuvelisa amandla okubangelwa kumngcipheko wokungaphumeleli kobuchwephesha be-TOP20 besikhululo samandla, umonakalo kunye nokutshiswa kombane.PV DC isidibanisiindawo yesibini.

Kumxholo wokufezekisa "injongo ezimbini zekhabhoni", kuqikelelwa ukuba kule minyaka mihlanu izayo, ilizwe lam unyaka omtsha wonyaka we-photovoltaic umthamo ofakiweyo uya kufikelela kwi-62 ukuya kwi-68 GW, kunye neChina eyongezelelekileyo efakelweyo umthamo wezikhululo zamandla ephotovoltaic ziya kufikelela kwi-561 GW 2025.

Kubonwa kwangaphambili ukuba ingaba isikhululo samandla esiphantsi komhlaba okanye isikhululo samandla esabiweyo, umthamo ofakelweyo we-photovoltaic uya kungena kwinqanaba lokukhula okukhulu, kodwa kukho imiba engakumbi yokhuseleko ehamba nayo, eye yatsala ingqalelo. yoshishino.

Ukhuseleko lubomi bezityalo zamandla e-photovoltaic, kwaye ikwasisiseko sokufumana imbuyekezo kutyalo-mali.Kungakhathaliseki ukuba zeziphi izigcawu zezityalo zamandla e-photovoltaic emhlabeni, entabeni, phezu kophahla, njl., ukhuseleko ngumgaqo-siseko.

Iingozi ezintathu ezifihliweyo kwiZityalo zaMandla ze-Photovoltaic

Kukho izizathu ezithathu eziphambili zengxaki yengozi yesikhululo samandla e-photovoltaic:

Okokuqala, iphaneli yelanga yePV DC isinxibelelanisi, esaziwa ngokuba sisidibanisi seMC4.Xa amandla e-PV modules eba mkhulu kwaye ekhudlwana, okwangoku kuya kwanda ngokufanelekileyo.Kule meko, ikhonkco yepaneli yelanga itshisa ngakumbi nangakumbi, eyenza ingozi yomlilo.Ke ngoko, isidibanisi sesinye sezona ndawo zinomlilo kakhulu kwikhonkco elisecaleni le-DC lemodyuli.

Okwesibini, ibhokisi yokudibanisa i-PV DC.Kwibhokisi yokudibanisa i-DC, kukho iintambo ezicwangcisiweyo ezixineneyo kunye nezixhobo zombane, kunye nebhokisi yentsimbi evaliweyo.Kwindawo yesakhiwo esitywiniweyo, ukushisa kwezixhobo zombane kunye namanqaku okudibanisa kwibhokisi kuya kuba phezulu, kwaye akulula ukutshabalalisa ukushisa.Kwimeko yokusebenza kwexesha elide Ngaphantsi kweemeko, iingxaki ezifana nokufudumeza kunye nokukhubeka kwezixhobo zombane zixhomekeke ekubeni zibe yingozi efihliweyo yomlilo.

Okwesithathu, iintambo zombane ophakathi kunye nophezulu.Kwizikhululo zamandla, iisistim zombane zamandla ombane aphakathi angama-35 kV kunye ne-110kV/220kV iinkqubo zokunyusa amandla ombane aphezulu zixhaphakile.Umgangatho wombane weemveliso zombane ophakathi kunye nophezulu uphezulu noko.Iimveliso ze-cable accessory zivame ukukhutshwa kunye neengxaki zokuqhawula.Ngoko ke, oku kwakhona photovoltaic Enye yeengozi ezifihliweyo zeengozi zesikhululo samandla.

KwiSikhululo saMandla sePV esiPhezulu se-20 yokuFaila koBuchule, i-PV DC Connector ibekwe kwindawo yesibini

Inokubonwa kuhlalutyo lwezi zizathu zintathu zingasentla ukuba iingozi ezinokubakho zokhuseleko eziziswa yi-PV DC isinxibelelanisi asinakuhoywa!Ngaphandle koko, iingozi ezinjengomlilo wekhonkco, ukudinwa,Ibhokisi yokuhlangana yePVukusilela, ukuvuza kwecandelo, kunye nokusilela kwamandla kumacandelo omtya kuya kwenzeka kamva.

Ngokutsho kwengxelo ekhutshwe liqela leprojekthi ye "Solar Bankability" yesicwangciso se-European Union Horizon 2020, umonakalo odityanisiweyo kunye nokutshiswa kwinqanaba lesibini ekulahlekeni kwengeniso yokuvelisa amandla okubangelwa umngcipheko wesikhululo samandla i-TOP 20 ukungaphumeleli kobugcisa.

Ukulahleka kwengeniso yokuvelisa amandla okubangelwa umngcipheko wesikhululo samandla se-photovoltaic esiphezulu se-20 yokusilela kweteknoloji

Kutheni iPV DC Iziqhagamshelo zibaluleke kangaka?

1. Sebenzisa ubuninzi obuninzi.Kwiinkqubo ze-photovoltaic, izixhumi zisetyenziswa kwiipaneli zelanga, ii-inverters ukuya kwindawo yeprojekthi.Inkqubo ye-photovoltaic ye-1MW mhlawumbi iya kusebenzisa iiseti ze-2000 ukuya kwi-3000 ye-PV DC izixhumi ngokwamandla eemodyuli ezisetyenzisiweyo.

2. Umngcipheko onokwenzeka uphezulu.Isethi nganye yezixhumi ze-PV DC iqulethe iindawo ezinobungozi ze-3 (iindawo zokudibanisa, ii-terminals ezintle kunye nezibi kunye neengxenye ze-cable crimping), oku kuthetha ukuba kwinkqubo ye-1MW, umdibanisi unokuzisa i-6000 kwi-9000 yengozi.Kwimeko yokuhamba kwangoku, ukunyuka kokuchasana koqhagamshelwano lwekhonkco kuya kubangela ukunyuka kweqondo lokushisa.Ukuba idlula iqondo lobushushu ukuba iqokobhe zeplastiki kunye neenxalenye zetsimbi ziyakwazi ukumelana, isinxibelelanisi kulula kakhulu ukusilela okanye nokuba kubangele umlilo.

3. Ubunzima ekusebenzeni nasekugcinweni kwendawo.Uninzi lwesoftware ekhoyo yokubeka iliso inokubeka esweni kuphela kwinqanaba lomtya.Ngeziphoso ezithile kumtya, ulungiso lweengxaki kwisiza lusafuneka.Oku kuthetha ukuba ukuba kukho ingxaki ngesidibanisi seMC4, kufuneka sijongwe nganye nganye.Kwizikhululo zamandla zoshishino kunye nezorhwebo (umbala we-tile yentsimbi), ukusebenza kunye nokugcinwa kunzima kakhulu.Abasebenzi kufuneka bakhwele phezu kophahla baze bavule ngesandla iipaneli zelanga, ezithatha ixesha kwaye zinzima.

4. Ukusetyenziswa kwamandla amakhulu.Isidibanisi sePV ngokwaso asivelisi amandla, sisidluliseli samandla.Kwinkqubo yokuhanjiswa kwamandla, kukho ilahleko.Ukuba kubalwa nge-avareji yokumelana noqhagamshelwano lweziqhagamshelo kwimarike, isikhululo sombane esingama-50MW siya kusebenzisa malunga ne-2.12 yezigidi zekWh zombane ngenxa yeziqhagamshelo kwisithuba seminyaka engama-25 yokusebenza.

Ukuqhutyelwa yimigaqo-nkqubo kulo nyaka, ukwakhiwa kwezityalo zamandla e-photovoltaic zihamba ngokupheleleyo, kwaye injongo yokungathathi hlangothi kwekhabhoni kunye ne-carbon peaking inokulindeleka, kodwa imfuno efunekayo kuyo yonke le nto kufuneka ibe ukhuseleko.Iinkampani zokudibanisa i-Photovoltaic nazo kufuneka zicebise izisombululo ezitsha kwingxaki yokhuseleko, ukwenzela ukunciphisa ukwenzeka kweengozi zokhuseleko ngexesha lokusebenza kwezikhululo zamandla e-photovoltaic, kunye nokwenza indlela yethu yokungathathi hlangothi kwekhabhoni izinzile kwaye isebenze.
