Pa-grid ndi off-grid operation mode ya solar photovoltaic power generation system

Ndi chidwi cha chitetezo cha chilengedwe ndi mphamvu zowonjezereka, mphamvu ya dzuwa ya photovoltaic monga njira yobiriwira komanso yoyera yamphamvu yachititsa chidwi kwambiri. Mu dongosolo la mphamvu ya dzuwa la photovoltaic, njira yake yogwiritsira ntchito pa-grid ndi off-grid ndiyofunika kwambiri.

Njira yogwiritsira ntchito pa gridi yamagetsi yolumikizidwa ndi gridi ya solar photovoltaic power generation system, magetsi opangira magetsi amalumikizidwa ndi mphamvu zamagetsi, ndipo magetsi opangidwa ndi makina opanga magetsi a photovoltaic amatha kudyetsedwa mu gridi yamagetsi kuti apereke. ogwiritsa.

Njira yogwiritsira ntchito pa gridi ili ndi izi:

1. Njira ziwiri zotumizira mphamvu: mumagetsi ogwiritsira ntchito gridi, makina opanga magetsi a photovoltaic amatha kupeza njira ziwiri zotumizira mphamvu, ndiko kuti, dongosolo likhoza kupeza magetsi kuchokera ku gridi yamagetsi, ndipo lingathenso kuyankha mphamvu zowonjezera mphamvu grid yamagetsi. Chikhalidwe chopatsirana cha njira ziwirizi chimapangitsa kuti photovoltaic mphamvu yopangira mphamvu yamagetsi isamangopatsa ogwiritsa ntchito mphamvu yokhazikika komanso yodalirika, komanso imatumiza mphamvu zowonjezera magetsi ku gridi, kuchepetsa mphamvu zowonongeka.

2. Kusintha kwachidziwitso: Mphamvu yopangira mphamvu ya photovoltaic imatha kusintha mphamvu yake yotulutsa mphamvu molingana ndi mlingo wamakono ndi wamagetsi wamagetsi amagetsi mumagetsi ogwiritsira ntchito grid kuti apitirize kugwira ntchito mokhazikika. Ntchito yosinthira yokhayo imatha kupititsa patsogolo mphamvu zamagetsi zamagetsi zamtundu wa photovoltaic, ndikuwonetsetsa chitetezo ndi kukhazikika kwa netiweki yamagetsi.

3. Kusungirako mphamvu yamagetsi: mphamvu ya photovoltaic yopangira magetsi mu gridi yolumikizidwa ndi njira yogwiritsira ntchito ingagwiritsidwe ntchito ngati mphamvu yowonjezera mphamvu. Mphamvu yamagetsi ikalephera kapena kulephera kwamagetsi, makinawo amatha kusinthana ndi malo opangira magetsi kuti apatse ogwiritsa ntchito mphamvu yokhazikika. Izi zimathandiza kuti magetsi a photovoltaic apangidwe mumagetsi ogwiritsira ntchito grid kuti apereke chitetezo chodalirika cha mphamvu pamene magetsi akulephera.

Njira yogwiritsira ntchito pa gridi yochokera ku gridi ikufanana ndi njira yogwiritsira ntchito gridi, ndipo mphamvu yopangira mphamvu ya dzuwa ya photovoltaic sichimalumikizidwa ndi gridi yamagetsi mumayendedwe opangira magetsi, ndipo dongosololi likhoza kugwira ntchito palokha ndikupereka mphamvu kwa ogwiritsa ntchito.

Makhalidwe a off-grid operation mode ndi awa:

1. Mphamvu yodziyimira payokha: Mphamvu yopangira mphamvu ya photovoltaic mumayendedwe a off-grid sichidalira maukonde aliwonse akunja amagetsi, ndipo imatha kupereka mphamvu kwa ogwiritsa ntchito. Mbali imeneyi ya magetsi odziyimira pawokha imapangitsa kuti makina opanga magetsi a photovoltaic akhale ndi zofunikira zogwiritsira ntchito kumadera akutali kapena malo omwe mulibe mwayi wopita ku gridi yamagetsi.

2. Dongosolo losungiramo mphamvu: Pofuna kuonetsetsa kuti mphamvu ya photovoltaic yopangira mphamvu mu njira yogwiritsira ntchito off-grid ikhoza kupereka mphamvu kwa ogwiritsa ntchito tsiku lonse, dongosololi nthawi zambiri limakhala ndi zida zosungiramo mphamvu, monga mapaketi a batri. Chipangizo chosungira mphamvu chimatha kusunga magetsi opangidwa ndi mphamvu ya photovoltaic masana ndikupereka mphamvu kwa ogwiritsa ntchito usiku kapena pansi pa kuwala kochepa.

3. Kasamalidwe ka mphamvu: makina opangira magetsi a photovoltaic mumayendedwe a off-grid nthawi zambiri amakhala ndi njira yanzeru yoyendetsera mphamvu, yomwe imatha kuyang'anira nthawi yeniyeni momwe makina amapangira mphamvu, kuchuluka kwamagetsi kwa wogwiritsa ntchito komanso momwe amalipira ndi kutulutsa. za zida zosungiramo mphamvu kuti zitheke kugwiritsa ntchito bwino ndikugawa mphamvu.

Mitundu yogwiritsira ntchito gridi yolumikizidwa ndi gridi yamagetsi opangira mphamvu ya solar photovoltaic ili ndi zabwino zawo, ndipo njira zoyenera zogwirira ntchito zitha kusankhidwa pazosankha ndi zosowa zosiyanasiyana. Ku China, ndikukula kosalekeza kwaukadaulo wopangira magetsi a solar photovoltaic ndi thandizo la mfundo, dongosolo lopangira mphamvu za solar photovoltaic lidzakhala ndi chiyembekezo chogwiritsa ntchito mtsogolo.
