Anthu ena amanena kuti mtengo wa photovoltaic inverter ndi wapamwamba kwambiri kuposa gawoli, ngati osagwiritsa ntchito mokwanira mphamvu zambiri, zidzasokoneza chuma.Choncho, akuganiza kuti mphamvu zonse zopangira magetsi zikhoza kuwonjezeka powonjezera ma modules a photovoltaic pogwiritsa ntchito mphamvu yowonjezera yowonjezera ya inverter.Koma kodi zilidi choncho?

Ndipotu zimenezi si zimene mnzawoyo ananena.Photovoltaic inverter ndi photovoltaic module ratio kwenikweni ndi gawo la sayansi.Kuphatikizika koyenera kokha, kuyika kwasayansi kungapereke kusewera kwathunthu ku magwiridwe antchito a gawo lililonse, kuti akwaniritse bwino kwambiri mphamvu zamagetsi zamagetsi.Zinthu zambiri ziyenera kuganiziridwa pakati pa inverter ya photovoltaic ndi gawo la photovoltaic, monga kukwezeka kwa kuwala, njira yoyika, malo, chinthu, module ndi inverter yokha ndi zina zotero.

Choyamba, light elevation factor

Madera dzuwa mphamvu gwero akhoza kugawidwa m'magulu asanu, woyamba, wachiwiri ndi wachitatu mitundu ya madera kuwala gwero ndi wolemera, ambiri a dziko lathu ndi m'makalasi amenewa, choncho ndi abwino kwambiri unsembe photovoltaic mphamvu m'badwo dongosolo.Komabe, mphamvu ya radiation imasiyanasiyana kwambiri m'madera osiyanasiyana.Nthawi zambiri, kuchuluka kwa kutalika kwa dzuwa kumakhala kokulirapo, mphamvu ya ma radiation yadzuwa, komanso kutalika kwake, kumapangitsanso mphamvu ya dzuwa.M'madera omwe ali ndi mphamvu zambiri za dzuwa, kutentha kwa kutentha kwa photovoltaic inverter kumakhala kovutirapo, kotero inverter iyenera kuchepetsedwa kuti igwire ntchito, ndipo chiwerengero cha zigawozo chidzakhala chochepa.

Awiri, unsembe zinthu

Chiŵerengero cha inverter ndi chigawo cha siteshoni yamagetsi ya photovoltaic chimasiyana ndi malo oyika ndi njira.

1.Dc mbali dongosolo mphamvu

Chifukwa mtunda pakati pa inverter ndi module ndi yochepa kwambiri, chingwe cha DC ndi chachifupi kwambiri, ndipo kutayika kumakhala kochepa, mphamvu ya mbali ya DC imatha kufika 98%.Chifukwa chingwe cha DC ndi chachitali, mphamvu yochokera ku kuwala kwa dzuwa kupita ku gawo la photovoltaic iyenera kudutsa chingwe cha DC, bokosi la confluence, kabati yogawa DC ndi zipangizo zina, komanso mphamvu ya mbali ya DC nthawi zambiri imakhala pansi pa 90% .

2. Kusintha kwamagetsi amagetsi amagetsi

Mphamvu yapamwamba yotulutsa mphamvu ya inverter sinthawi zonse.Ngati gridi yolumikizidwa ndi gridi ikugwa, ndiye kuti inverter siyingafikire zomwe zidavotera.Tiyerekeze kuti tatengera 33kW inverter, pazipita linanena bungwe panopa ndi 48A ndi oveteredwa linanena bungwe voteji ndi 400V.Malinga ndi njira yowerengera mphamvu ya magawo atatu, mphamvu yotulutsa ndi 1.732 * 48 * 400 = 33kW.Ngati magetsi a gridi agwera ku 360, mphamvu yotulutsa idzakhala 1.732 * 48 * 360 = 30kW, yomwe siingafikire mphamvu yovomerezeka.Kupangitsa kupanga magetsi kukhala kosavuta.

3.inverter kutentha kutentha

Kutentha kwa inverter kumakhudzanso mphamvu yotulutsa inverter.Ngati inverter kutentha dissipation zotsatira ndi osauka, ndiye linanena bungwe mphamvu adzachepa.Chifukwa chake, inverter iyenera kukhazikitsidwa popanda kuwala kwa dzuwa, mpweya wabwino.Ngati malo oyikapo sali bwino, ndiye kuti kuchotsera koyenera kuyenera kuganiziridwa kuti muteteze inverter kuti isatenthedwe.

Atatu.Zigawo zokha

Ma module a Photovoltaic nthawi zambiri amakhala ndi moyo wautumiki wa zaka 25-30.Pofuna kuonetsetsa kuti gawoli likhoza kukhalabe bwino kuposa 80% pambuyo pa moyo wautumiki wabwinobwino, fakitale yayikulu ya module imakhala ndi malire okwanira 0-5% popanga.Kuonjezera apo, timakhulupirira kuti machitidwe ogwiritsira ntchito module ndi 25 °, ndipo kutentha kwa photovoltaic kumachepa, mphamvu ya module idzawonjezeka.

Zinayi, ma inverter eni ake

1.inverter ntchito bwino ndi moyo

Ngati tipanga inverter kugwira ntchito mwamphamvu kwambiri kwa nthawi yayitali, moyo wa inverter udzachepetsedwa.Kafukufuku akuwonetsa kuti moyo wa inverter ukugwira ntchito pa 80% ~ 100% mphamvu imachepetsedwa ndi 20% kuposa 40% ~ 60% kwa nthawi yayitali.Chifukwa chakuti dongosololi lidzawotchera kwambiri pamene likugwira ntchito pa mphamvu zambiri kwa nthawi yaitali, kutentha kwa kayendetsedwe ka kayendetsedwe kake kumakhala kokwera kwambiri, komwe kumakhudza moyo wautumiki.

2,njira yabwino kwambiri yogwiritsira ntchito magetsi a inverter

Inverter yogwira ntchito pamagetsi ovotera, mphamvu yapamwamba kwambiri, gawo limodzi 220V inverter, inverter input ovotera voteji 360V, magawo atatu 380V inverter, input oveteredwa voteji 650V.Monga 3 kw photovoltaic inverter, ndi mphamvu ya 260W, mphamvu yogwira ntchito ya 30.5V 12 midadada ndiyo yoyenera kwambiri;Ndipo 30 kW inverter, kugawa mphamvu kwa zigawo za 260W zidutswa 126, ndiyeno njira iliyonse 21 zingwe ndizoyenera kwambiri.

3. Kuchulukirachulukira kwa inverter

Ma inverter abwino nthawi zambiri amakhala ndi mphamvu zambiri, ndipo mabizinesi ena alibe mphamvu zambiri.Inverter yokhala ndi mphamvu zambiri zodzaza imatha kudzaza mphamvu zochulukirapo 1.1 ~ 1.2, imatha kukhala ndi zigawo 20% kuposa inverter popanda kuchulukitsidwa.

Photovoltaic inverter ndi module sizongochitika mwachisawawa komanso, kuti zikhale zomveka bwino, kuti mupewe kutayika.Mukayika malo opangira magetsi a photovoltaic, tiyenera kuganizira mozama zinthu zosiyanasiyana, ndikusankha mabizinesi a photovoltaic omwe ali ndi ziyeneretso zabwino kwambiri zoyikira.
