Photovoltaic ndi chiyani, kusungirako mphamvu ndi chiyani, chosinthira, inverter ndi chiyani, PCS ndi mawu ena osakira
01, Kusungirako mphamvu ndi photovoltaic ndi mafakitale awiri
Ubale pakati pawo ndi wakuti photovoltaic system imasintha mphamvu ya dzuwa kukhala mphamvu yamagetsi, ndipo mphamvu yosungiramo mphamvu imasunga mphamvu yamagetsi yopangidwa ndi zipangizo za photovoltaic. Gawo ili la mphamvu yamagetsi likafunika, limasinthidwa kukhala magetsi osinthika kudzera mu chosinthira chosungira mphamvu kuti chizigwiritsidwa ntchito ponyamula kapena kugwiritsa ntchito grid.
02, Kufotokozera mawu ofunikira
Malinga ndi kufotokozera kwa Baidu: m'moyo, nthawi zina zimafunika kusintha magetsi a AC kukhala magetsi a DC, omwe ndi dera lowongolera, ndipo nthawi zina, ndikofunikira kusintha magetsi a DC kukhala magetsi a AC. Njira yosinthirayi yofananira ndi kukonzanso imatanthauzidwa ngati inverter circuit. Pazifukwa zina, seti ya mabwalo a thyristor angagwiritsidwe ntchito ngati ma rectifier circuit komanso inverter circuit. Chipangizochi chimatchedwa chosinthira, chomwe chimaphatikizapo zosinthira, zosinthira, zosintha za AC, ndi zosinthira DC.
Timvetsetsenso:
Chingerezi cha converter ndi chosinthira, chomwe chimazindikirika ndi zida zamagetsi zamagetsi, ndipo ntchito yake ndikuzindikira kufalikira kwa mphamvu. Malingana ndi mitundu yosiyanasiyana ya magetsi asanayambe komanso atatha kutembenuka, amagawidwa m'magulu awa:
DC / DC converter, kutsogolo ndi kumbuyo ndi DC, magetsi ndi osiyana, ntchito ya DC transformer
AC/DC converter, AC to DC, udindo wa rectifier
DC / AC converter, DC kuti AC, udindo wa inverter
AC/AC converter, ma frequency akutsogolo ndi kumbuyo ndi osiyana, ntchito ya frequency converter
Kuphatikiza pa dera lalikulu (motengera rectifier circuit, inverter circuit, AC conversion circuit ndi DC conversion circuit), chosinthiracho chiyeneranso kukhala ndi chozungulira (kapena kuyendetsa galimoto) kuti chiwongolere kuyatsa kwa chinthu chosinthira mphamvu ndi kuzindikira kuwongolera mphamvu yamagetsi, kuwongolera dera.
Dzina lachingerezi la converter yosungirako mphamvu ndi Power Conversion System, yotchedwa PCS, yomwe imayang'anira kuyendetsa ndi kutulutsa batri ndikuchita kutembenuka kwa AC-DC. Amapangidwa ndi DC/AC bidirectional converter ndi unit control unit.
03, PCS gulu lonse
Ikhoza kugawidwa m'mafakitale awiri osiyana, photovoltaic ndi yosungirako mphamvu, chifukwa ntchito zofananira ndizosiyana kwambiri:
M'makampani a photovoltaic, pali: mtundu wapakati, mtundu wa chingwe, inverter yaying'ono
Inverter-DC kupita ku AC: Ntchito yayikulu ndikutembenuza mphamvu yachindunji yotembenuzidwa ndi mphamvu ya dzuwa kuti ikhale yosinthika kudzera pazida za photovoltaic, zomwe zingagwiritsidwe ntchito ndi katundu kapena kuphatikizidwa mu gridi kapena kusungidwa.
Chapakati: kuchuluka kwa ntchito ndi malo opangira magetsi akuluakulu, ma photovoltais ogawidwa m'mafakitale ndi amalonda, ndipo mphamvu yotulutsa ndi yayikulu kuposa 250KW.
Mtundu wa zingwe: kuchuluka kwa ntchito ndi malo opangira magetsi akuluakulu, ma photovoltaics omwe amagawidwa m'mafakitale ndi malonda (mphamvu zonse zotulutsa zosakwana 250KW, magawo atatu), ma photovoltaics apanyumba (mphamvu zotulutsa mphamvu zosakwana kapena zofanana ndi 10KW, gawo limodzi) ,
Micro-inverter: kukula kwa ntchito kumagawidwa ndi photovoltaic (mphamvu yotulutsa mphamvu ndi yocheperapo kapena yofanana ndi 5KW, magawo atatu), photovoltaic yapakhomo (mphamvu zotulutsa mphamvu ndizochepera kapena zofanana ndi 2KW, gawo limodzi)
Machitidwe osungira mphamvu akuphatikiza: kusungirako kwakukulu, kusungirako mafakitale ndi malonda,zosungiramo nyumba, ndipo akhoza kugawidwa m'magulu osungira mphamvu (otembenuza magetsi achikhalidwe, Hybrid) ndi makina ophatikizika
Kutembenuka kwa Converter-AC-DC: Ntchito yayikulu ndikuwongolera kuthamanga ndi kutulutsa kwa batri. Mphamvu ya DC yopangidwa ndi mphamvu ya photovoltaic imasinthidwa kukhala mphamvu ya AC kudzera mu inverter. Mphamvu yosinthira imasinthidwa kukhala yachindunji polipira. Gawo ili la mphamvu yamagetsi likafunika, mphamvu yachindunji mu batire iyenera kusinthidwa kukhala yosinthira (nthawi zambiri 220V, 50HZ) ndi chosinthira chosungira mphamvu kuti chigwiritsidwe ntchito ndi katundu kapena kulumikizidwa ku gridi. Uku ndikutulutsa. ndondomeko.
Kusungirako kwakukulu: malo opangira magetsi, malo osungira magetsi odziyimira pawokha, mphamvu zambiri zotulutsa ndizokulirapo kuposa 250KW
Kusungirako mafakitale ndi malonda: mphamvu zambiri zotulutsa ndizochepera kapena zofanana ndi 250KW
Kusungirako m'nyumba: mphamvu zotulutsa zonse ndizochepera kapena zofanana ndi 10KW
Zosintha zachikhalidwe zosungira mphamvu: makamaka amagwiritsa ntchito chiwembu cholumikizira cha AC, ndipo mawonekedwe ogwiritsira ntchito amakhala malo osungira ambiri.
Hybrid inverter: makamaka amatengera chiwembu chophatikizana cha DC, ndipo mawonekedwe ogwiritsira ntchito amakhala makamaka kusungira kunyumba
Inverter zonse mu chimodzi: chosinthira chosungira mphamvu + batire paketi, zinthuzo ndi Tesla ndi Ephase
