PV DC Zolumikizira Kuti Zisamanyalanyazidwe Mu Solar Photovoltaic Station

Mothandizidwa ndi ndondomeko zosiyanasiyana, kumangidwa kwa magetsi a photovoltaic kuli bwino, ndipo nkhani za chitetezo ndizofunika kwambiri.Lipotilo likuwonetsa kuti pakutayika kwa ndalama zopangira magetsi chifukwa cha kulephera kwaukadaulo wa TOP20 wa malo opangira magetsi, kuwonongeka ndi kuwotcha kwa magetsi.PV DC cholumikiziraadakhala pachiwiri.

Pankhani yokwaniritsa "cholinga chapawiri cha kaboni", akuti m'zaka zisanu zikubwerazi, dziko langa latsopano lapachaka la photovoltaic lidzafika pa 62 mpaka 68 GW, ndipo ku China kowonjezera mphamvu zopangira magetsi a photovoltaic kudzafika 561 GW mu 2025.

Zikuwonekeratu kuti kaya ndi malo opangira magetsi kapena magetsi ogawidwa, mphamvu yoyikidwa ya photovoltaic idzalowa mu siteji ya kukula kwakukulu, koma pali zowonjezereka zokhudzana ndi chitetezo zomwe zimabwera nazo, zomwe zachititsa chidwi. za makampani.

Chitetezo ndiye maziko amagetsi opangira magetsi a photovoltaic, komanso ndiye maziko opezera ndalama.Mosasamala kanthu za zochitika za magetsi a photovoltaic pansi, paphiri, padenga, etc., chitetezo ndi mfundo.

Zowopsa Zitatu Zobisika mu Zomera Zamagetsi za Photovoltaic

Pali zifukwa zitatu zazikuluzikulu za vuto la ngozi ya malo opangira magetsi a photovoltaic:

Choyamba, cholumikizira cha solar PV DC, chomwe chimadziwika kuti cholumikizira cha MC4.Pamene mphamvu za PV modules zimakhala zazikulu ndi zazikulu, zamakono zidzawonjezeka moyenerera.Pankhaniyi, cholumikizira cha solar chimatenthetsa kwambiri, zomwe zimapangitsa kuti pakhale ngozi yamoto.Chifukwa chake, cholumikizira ndi chimodzi mwazinthu zomwe zimayaka moto kwambiri mu ulalo wa mbali ya DC wa module.

Chachiwiri, bokosi lophatikiza la PV DC.M'bokosi lophatikizira la DC, pali mizere yokonzedwa bwino ndi zida zamagetsi, kuphatikiza bokosi lachitsulo lotsekedwa.Mu chilengedwe chosindikizidwa, kutentha kwa zipangizo zamagetsi ndi malo olumikizirana mubokosilo kudzakhala kwakukulu, ndipo sikophweka kutaya kutentha.Pankhani yogwira ntchito kwa nthawi yayitali Muzochitika, mavuto monga kutentha ndi kugwedezeka kwa zipangizo zamagetsi zimakhala zoopsa zobisika zamoto.

Chachitatu, sing'anga ndi mkulu voteji chingwe olowa.M'malo opangira magetsi, ma 35 kV medium voltage aelectric system ndi 110kV/220kV high voltage boost systems ndizofala.Mphamvu yamagetsi yamagetsi apakati ndi apamwamba ndi yokwera kwambiri.Zopangira zida zama chingwe zimakhala zovuta kutulutsa pang'ono komanso kuwonongeka.Choncho, izi ndi photovoltaic Chimodzi mwa zoopsa zobisika za ngozi zapamagetsi.

Mu PV Power Station Top 20 Technical Failure, PV DC Connector Inakhala Yachiwiri

Zitha kuwoneka kuchokera pakuwunika kwazifukwa zitatu zomwe zili pamwambazi kuti zoopsa zomwe zingabweretsedwe ndi cholumikizira cha PV DC sizinganyalanyazidwe!Apo ayi, ngozi monga cholumikizira moto, kutopa,PV mphambano bokosikulephera, kutayikira kwa gawo, ndi kulephera kwamphamvu kwa zigawo za chingwe zidzachitika mtsogolo.

Malinga ndi lipoti lomwe linatulutsidwa ndi gulu la polojekiti ya "Solar Bankability" ya dongosolo la European Union's Horizon 2020, kuwonongeka kwa cholumikizira ndi kupsa mtima kuli pamalo achiwiri pakutayika kwa ndalama zopangira magetsi chifukwa cha chiwopsezo cha kulephera kwaukadaulo kwa TOP 20.

Kutayika kwa ndalama zopangira magetsi chifukwa cha chiopsezo cha photovoltaic power station top 20 technology failure

Chifukwa chiyani ma PV DC Connectors ali Ofunika Kwambiri?

1. Gwiritsani ntchito kuchuluka kwambiri.Mu machitidwe a photovoltaic, zolumikizira zimagwiritsidwa ntchito kuchokera ku solar panel, inverters kupita kumalo a polojekiti.Dongosolo la 1MW photovoltaic mwina lidzagwiritsa ntchito ma seti 2000 mpaka 3000 a zolumikizira za PV DC molingana ndi mphamvu zama module omwe amagwiritsidwa ntchito.

2. Chiwopsezo chomwe chingakhalepo ndi chachikulu.Seti iliyonse ya zolumikizira za PV DC ili ndi malo owopsa a 3 (magawo olumikizira, ma terminals abwino ndi oyipa ndi zida zomangira chingwe), zomwe zikutanthauza kuti mu dongosolo la 1MW, cholumikizira chikhoza kubweretsa 6000 mpaka 9000 malo owopsa.Pankhani ya kutuluka kwaposachedwa, kuwonjezeka kwa kukana kukhudzana kwa cholumikizira kudzatsogolera kuwonjezeka kwa kutentha.Ngati ipitilira kutentha komwe chipolopolo cha pulasitiki ndi zitsulo zimatha kupirira, cholumikizira chimakhala chosavuta kulephera kapena kuyambitsa moto.

3. Kuvuta kugwira ntchito ndi kukonza pa malo.Mapulogalamu ambiri owunikira omwe alipo amatha kungoyang'ana pamlingo wa chingwe.Pazolakwa zinazake mu chingwe, kuthetseratu pa tsamba kumafunikabe.Izi zikutanthauza kuti ngati pali vuto ndi cholumikizira cha MC4, chiyenera kufufuzidwa chimodzi ndi chimodzi.Kwa malo opangira magetsi opangira mafakitale ndi malonda (madenga amtundu wazitsulo zachitsulo), kugwira ntchito ndi kukonza kumakhala kovuta kwambiri.Ogwira ntchito amayenera kukwera padenga ndikutsegula pamanja ma solar panels, zomwe zimawononga nthawi komanso zovuta.

4. Kugwiritsa ntchito mphamvu kwakukulu.Chojambulira cha PV chokha sichimapanga mphamvu, ndi chotumizira mphamvu.M'kati mwa kufalitsa mphamvu, payenera kukhala kutaya.Ngati kuwerengeredwa ndi kukana kwapafupipafupi kwa zolumikizira pamsika, malo opangira magetsi a 50MW adzawononga pafupifupi 2.12 miliyoni kWh yamagetsi chifukwa cha zolumikizira mkati mwazaka 25 zogwira ntchito.

Moyendetsedwa ndi ndondomeko chaka chino, ntchito yomanga magetsi a photovoltaic ikupita patsogolo, ndipo cholinga cha kusalowerera ndale kwa carbon ndi carbon peaking chingayembekezere, koma chofunikira pa zonsezi chiyenera kukhala chitetezo.Makampani opangira ma photovoltaic amayeneranso kupereka njira zothetsera vuto lachitetezo, kuti achepetse kuchitika kwa ngozi zachitetezo panthawi yopangira magetsi a photovoltaic, ndikupanga njira yathu yopita ku ndale ya kaboni kukhala yokhazikika komanso yothandiza.
