Mapangidwe Ndi Magulu A Grid-Connected Photovoltaic Power Generation Systems

Gulu lawolumikizidwa ndi gridmakina opanga magetsi a photovoltaic

Makina opangira magetsi olumikizidwa ndi gridi amatha kugawidwa m'makina olumikizana ndi gridi, osalumikizana ndi gridi, makina olumikizidwa ndi gridi, makina olumikizidwa ndi gridi, DC ndi AC makina olumikizidwa ndi gridi, ndi makina olumikizidwa ndi gridi malinga ndi magetsi. mphamvu imatumizidwa ku dongosolo la mphamvu.

1. Njira yopangira magetsi yolumikizana ndi gridcurrent

Pamene mphamvu yopangidwa ndi mphamvu ya dzuwa photovoltaic mphamvu yowonjezera mphamvu, mphamvu yotsalira ikhoza kutumizidwa ku gridi ya anthu;pamene mphamvu yoperekedwa ndi solar photovoltaic power generation system ndi yosakwanira, gridi yamagetsi imapereka mphamvu ku katundu.Popeza mphamvu imaperekedwa ku gridi kumbali yotsutsana ndi gridi, imatchedwa countercurrent photovoltaic power generation system.

2. Njira yopangira magetsi yolumikizidwa ndi gridi popanda kutsutsana

Ngakhale mphamvu yopangira magetsi ya photovoltaic imapanga mphamvu zokwanira, sizipereka mphamvu ku gridi ya anthu.Komabe, pamene mphamvu yopangira mphamvu ya photovoltaic ya dzuwa imapereka mphamvu yosakwanira, idzagwiritsidwa ntchito ndi gridi ya anthu.

3. Kusintha makina opangira magetsi opangidwa ndi grid

Njira yopangira magetsi yolumikizidwa ndi gridi imakhala ndi ntchito yosinthira njira ziwiri zokha.Choyamba, pamene photovoltaic mphamvu yopangira mphamvu imapanga mphamvu zosakwanira chifukwa cha nyengo, kulephera kwa whiteout, etc., kusinthana kungasinthire ku mbali ya magetsi a gridi, ndipo gululi lamagetsi limapereka mphamvu ku katundu;chachiwiri, pamene gululi mphamvu mwadzidzidzi kutaya mphamvu pazifukwa zina, photovoltaic mphamvu mphamvu dongosolo Ikhoza kusintha basi kulekanitsa gululi mphamvu mphamvu photovoltaic dongosolo kupanga ndi kukhala odziimira photovoltaic mphamvu mphamvu dongosolo.Nthawi zambiri, makina opangira magetsi a gridi olumikizidwa ndi photovoltaic amakhala ndi zida zosungira mphamvu.

4. Njira yopangira mphamvu zamagetsi yolumikizidwa ndi gridi yosungiramo mphamvu

Magetsi opangidwa ndi magetsi a photovoltaic opangidwa ndi grid ndi chipangizo chosungira mphamvu ndikukonzekera chipangizo chosungirako mphamvu molingana ndi zofunikira mu mitundu yomwe yatchulidwa pamwambayi yamagetsi opangidwa ndi magetsi a photovoltaic.Mawonekedwe a Photovoltaic okhala ndi zida zosungiramo mphamvu amakhala okhazikika kwambiri ndipo amatha kugwira ntchito modziyimira pawokha ndikupereka mphamvu ku katundu nthawi zambiri pakakhala kutha kwa mphamvu, mphamvu yamagetsi kapena kulephera mu gridi yamagetsi.Choncho, makina opangira magetsi opangidwa ndi gridi opangidwa ndi magetsi omwe ali ndi mphamvu yosungiramo mphamvu angagwiritsidwe ntchito ngati njira yopangira magetsi kumalo ofunikira kapena katundu wadzidzidzi monga magetsi olankhulana mwadzidzidzi, zipangizo zamankhwala, malo opangira mafuta, malo otulutsirako komanso kuyatsa.

5. Njira yopangira magetsi yolumikizidwa ndi gridi yayikulu

Makina opangira magetsi opangira magetsi opangidwa ndi gridi yayikulu amapangidwa ndi magulu angapo opangira mphamvu zamagetsi amtundu wa photovoltaic.Chigawo chilichonse chopangira magetsi cha photovoltaic chimasintha mphamvu ya DC yopangidwa ndi ma solar array kukhala mphamvu ya 380V AC kudzera mu inverter yolumikizidwa ndi gridi ya photovoltaic, kenako ndikuisintha kukhala mphamvu yamagetsi ya 10KV AC kudzera pamagetsi owonjezera.Kenako imatumizidwa ku 35KV transformer system ndikuphatikizidwa mu mphamvu ya 35KV AC.Mu gridi yamagetsi okwera kwambiri, mphamvu ya 35KV AC yothamanga kwambiri imasinthidwa kukhala mphamvu ya 380 ~ 400V AC kudzera munjira yotsikira pansi ngati njira yosungira magetsi pamalo opangira magetsi.

6. Njira yopangira mphamvu zogawa

Kugawidwa kwa magetsi a photovoltaic, omwe amadziwikanso kuti magetsi ogawidwa kapena kugawidwa kwa magetsi, amatanthauza kasinthidwe kamagetsi ang'onoang'ono a photovoltaic pa malo ogwiritsira ntchito kapena pafupi ndi malo ogwiritsira ntchito mphamvu kuti akwaniritse zosowa za ogwiritsa ntchito enieni ndikuthandizira chuma cha network yogawa yomwe ilipo.opaleshoni, kapena zonse ziwiri.

7. Wanzeru microgrid dongosolo

Microgrid imatanthawuza njira yaying'ono yopangira mphamvu ndi kugawa yomwe imapangidwa ndi magwero amagetsi ogawidwa, zida zosungiramo mphamvu, zida zosinthira mphamvu, katundu wokhudzana, kuyang'anira ndi kuteteza zida.Ndi dongosolo lomwe limatha kuzindikira kudziletsa, chitetezo ndi chitetezo.Dongosolo lodziyimira loyang'anira limatha kugwira ntchito limodzi ndi gridi yamagetsi yakunja kapena kudzipatula.Microgrid imalumikizidwa ndi gawo la ogwiritsa ntchito ndipo imakhala ndi mawonekedwe otsika mtengo, magetsi otsika komanso kuipitsidwa kochepa.Microgrid imatha kulumikizidwa ku gridi yayikulu yamagetsi, kapena imatha kulumikizidwa ku gridi yayikulu ndikuyendetsa paokha pomwe gululi lamagetsi likulephera kapena likufunika.

Kupangidwa kwa grid-yolumikizidwa ndi photovoltaic power generation system

Mtundu wa photovoltaic umasintha mphamvu ya dzuwa kukhala mphamvu ya DC, ndikuiphatikiza kudzera mu bokosi lophatikiza, kenako ndikusintha mphamvu ya DC kukhala mphamvu ya AC kudzera mu inverter.Mphamvu yamagetsi yamagetsi yamagetsi ya photovoltaic yolumikizidwa ku gridi yamagetsi imatsimikiziridwa molingana ndi mphamvu ya malo opangira magetsi a photovoltaic otchulidwa ndi teknoloji yolumikizira malo opangira magetsi a photovoltaic ku gridi yamagetsi., pambuyo poti voliyumu ikuwonjezeredwa ndi transformer, imagwirizanitsidwa ndi gridi yamagetsi ya anthu.
