Kwa dongosolo lolumikizidwa ndi gridi ya solar, nthawi ndi nyengo zidzasintha ma radiation adzuwa, ndipo mphamvu yamagetsi pamagetsi imasintha nthawi zonse. Pofuna kuonjezera kuchuluka kwa magetsi omwe amapangidwa, zimatsimikiziridwa kuti magetsi a dzuwa amatha kuperekedwa ndipamwamba kwambiri pamene dzuŵa liri lofooka komanso lamphamvu. Mphamvu, nthawi zambiri njira yolimbikitsira imawonjezedwa ku inverter kuti ikulitse voteji pamalo ake ogwirira ntchito.
Zotsatirazi zing'onozing'ono zikufotokozera chifukwa chake muyenera kugwiritsa ntchito mphamvu zowonjezera, komanso momwe mphamvu zowonjezera zimathandizira dongosolo la mphamvu ya dzuwa kuti liwonjezere mphamvu zamagetsi.
N'chifukwa Chiyani Muyenera Kulimbikitsa Circuit?
Choyamba, tiyeni tione wamba inverter dongosolo msika. Imakhala ndi gawo lowonjezera lothandizira komanso gawo la inverter. Pakatikati amalumikizidwa kudzera pa basi ya DC.
Dera la inverter liyenera kugwira ntchito moyenera. Mabasi a DC ayenera kukhala apamwamba kuposa grid voltage peak (magawo atatu ndi apamwamba kuposa mtengo wapamwamba wamagetsi amagetsi), kuti mphamvuyo ikhale yotuluka ku gridi kutsogolo. Nthawi zambiri kuti igwire bwino ntchito, basi ya DC nthawi zambiri imasintha ndi grid voltage. , kuonetsetsa kuti ndipamwamba kuposa gridi yamagetsi.
Ngati voteji yamagulu ndi apamwamba kuposa voteji yofunikira ya busbar, inverter idzagwira ntchito mwachindunji, ndipo voteji ya MPPT idzapitirizabe kutsata mpaka kufika pamtunda waukulu. Komabe, mutatha kukwaniritsa zofunikira zochepa zamabasi, sizingachepetsenso, ndipo malo abwino kwambiri sangathe kukwaniritsidwa. Kukula kwa MPPT ndikotsika kwambiri, komwe kumachepetsa kwambiri mphamvu zamagetsi ndipo phindu la wogwiritsa ntchito silingatsimikizidwe. Chifukwa chake payenera kukhala njira yothetsera vutoli, ndipo mainjiniya amagwiritsa ntchito mabwalo a Boost boost kuti akwaniritse izi.
Kodi Boost Boost kuchuluka kwa MPPT kuonjezera kupanga magetsi?
Pamene magetsi a gululo ali apamwamba kuposa magetsi omwe amafunidwa ndi mabasi, chigawo cha boost booster chili mu mpumulo, mphamvu imaperekedwa ku inverter kudzera mu diode yake, ndipo inverter imamaliza kufufuza kwa MPPT. Pambuyo pofika pamagetsi ofunikira a busbar, inverter sangathe kutenga. MPPT inagwira ntchito. Panthawiyi, gawo la boost boost lidatenga ulamuliro wa MPPT, kutsatira MPPT, ndikukweza basi kuti iwonetsetse kuti magetsi ake.
Ndi kutsata kochulukira kwa MPPT, inverter system imatha kukhala ndi gawo lofunikira pakuwonjezera mphamvu yamagetsi a solar m'mawa, theka lausiku, ndi masiku amvula. Monga tikuonera pachithunzichi pansipa, mphamvu zenizeni zenizeni ndizodziwikiratu. Limbikitsani.
Chifukwa chiyani inverter yayikulu nthawi zambiri imagwiritsa ntchito mabwalo angapo a Boost kuti awonjezere kuchuluka kwa ma MPPT?
Mwachitsanzo, dongosolo la 6kw, motsatira 3kw mpaka madenga awiri, ma inverters awiri a MPPT ayenera kusankhidwa panthawiyi, chifukwa pali zigawo ziwiri zodziimira pawokha, dzuwa la m'mawa limatuluka kummawa, kukhudzana mwachindunji ndi A pamwamba pa solar panel. , magetsi ndi mphamvu kumbali ya A ndizokwera, ndipo mbali ya B ndi yotsika kwambiri, ndipo masana ndi osiyana. Pakakhala kusiyana pakati pa ma voltages awiri, magetsi otsika ayenera kulimbikitsidwa kuti apereke mphamvu ku basi ndikuwonetsetsa kuti imagwira ntchito pamtunda waukulu kwambiri.
Chifukwa chomwechi, mtunda wamapiri m'madera ovuta kwambiri, dzuwa lidzafunika kuwala kowonjezereka, kotero kumafunikira MPPT yodziimira payekha, kotero mphamvu yapakati ndi yapamwamba, monga 50Kw-80kw inverters nthawi zambiri imakhala 3-4 yodziimira pawokha, nthawi zambiri amati. 3-4 yodziyimira payokha MPPT.
