Kwa dongosolo lolumikizidwa ndi dzuwa, nthawi ndi nyengo idzayambitsa kusintha kwa dzuwa, ndipo magetsi pamagetsi amasintha nthawi zonse. Pofuna kuwonjezera kuchuluka kwa magetsi, zimatsimikiziridwa kuti dzuwa la dzuwa limatha kuperekedwa ndi zotulutsa zapamwamba pomwe dzuwa limafooka komanso lamphamvu. Mphamvu, nthawi zambiri yolimbitsa thupi limawonjezera njira imawonjezeredwa kwa involiyo kuti ifutukule voliyumu pogwira ntchito.
Mitundu yaying'ono yotsatirayi ikufotokoza chifukwa chake muyenera kugwiritsa ntchito kukulitsa mphamvu, komanso momwe kulimbikitsa kwa dongosolo lingathandizire mphamvu yamagetsi kuti muchulukitse mphamvu.
N'CHIYANI CIMAKONZEKERANI BWINO?
Choyamba, tiyeni tiwone njira wamba wamba pamsika. Imakhala yolimbitsa masikono komanso gawo lozungulira. Pakati imalumikizidwa kudzera pa basi ya DC.
Gawo lolowera lolowera liyenera kugwira ntchito moyenera. Basi ya DC iyenera kukhala yokwera kuposa nsonga yamphamvu kwambiri (kachitidwe katatu katatu ndikokwera kuposa mtengo wa chingwe cha chingwe), kuti mphamvu zitha kutulutsa mtsogolo. Nthawi zambiri pamavuto, bus ya DC nthawi zambiri imasintha ndi volidi ya Grid. , kuti zitsimikizike kuti ndizokwera kuposa mphamvu yamphamvu.
Ngati magetsi am'madzi ndi apamwamba kuposa voliyumu yofunikira ya Busbar, omwe amagwira ntchitoyo adzagwira ntchito mwachindunji, ndipo magetsi a MPT apitilizabe kutsatira malo okwanira. Komabe, atatha kufika ochepera magetsi ofunikira, sangathenso kuchepetsedwa, ndipo kwenikweni siyitheka. Kukula kwa MPPT ndi yotsika kwambiri, yomwe imachepetsa kwambiri kwa zaka zam'magetsi ndipo phindu la wogwiritsa ntchito silingatsimikiziridwe. Chifukwa chake payenera kukhala njira yopangira zotsalazo, ndipo mainjiniya amagwiritsa ntchito madera kuti akwaniritse izi.
Kodi Kulima Kukulitsa bwanji kuchuluka kwa MPPT kuti awonjezere mibadwo?
Pamene mphamvu ya gululi ndiyokwera kuposa voliyumu yofunikira ndi mabasi, mphamvu zimapumula, mphamvu zimafikiridwa kumodzi, ndipo wolowetsa amaliza kutsatira njira ya MPT. Pambuyo pofika magetsi ofunikira a Busbar, wolowetsa sangathe kulanda. MPPT idagwira ntchito. Pakadali pano, kulimbikitsa gawo linalambitsidwa kunawongolera MPT, anatsatila MPPT, ndikukweza busbar kuti iwonetsetse mphamvu yake.
Ndi gawo lalitali la MPT, dongosolo lomwe limatha kugwira ntchito yofunika kwambiri pakuwonjezera mphamvu ya magetsi pamwala, usiku, ndi mvula masiku. Monga tikuwonera m'chiwerengero pansipa, mphamvu zenizeni zikuwonekeratu. Kulimbikitsa.
Kodi ndichifukwa chiyani mgwirizano waukulu wamagetsi umagwiritsa ntchito kangapo kumalimbikitsa madera owonjezera kuchuluka kwa mabwalo a MPT?
Mwachitsanzo, dongosolo la 6kW, motsatana 3kW mpaka padenga awiri, chifukwa pali mfundo ziwiri zogwirira ntchito kuchokera kummawa, dzuwa ndi mphamvu yotsika kwambiri, ndipo masanawa ndi osiyana. Pakakhala kusiyana pakati pa magetsi awiri, mphamvu yotsika kwambiri imayenera kusungidwa kuti ipereke mphamvu m'basi ndikuwonetsetsa kuti imagwira ntchito mokwanira.
Chifukwa chomwechi, mabingu omwewo mtunda wovuta kwambiri, dzuwa lidzafunikira ma irradiation ambiri, motero imafunikira kwambiri martri oyimilira, omwe nthawi zambiri amakhala olimbikitsa 3-4 a MPPT.
