Mfundo yogwirira ntchito ya inverter ya photovoltaic

Mfundo Yogwirira Ntchito
Pakati pa chipangizo cha inverter, ndi dera losinthira la inverter, lotchedwa dera losinthira. Dera ili limakwaniritsa ntchito ya inverter kudzera mu conduction ndi kutseka ma switch amagetsi amphamvu.

Mawonekedwe
(1) Imafuna mphamvu zambiri. Chifukwa cha mtengo wapamwamba wa ma solar cells omwe alipo panopa, ndikofunikira kuyesa kukonza mphamvu ya inverter kuti igwiritse ntchito bwino ma solar cells ndikukweza mphamvu ya makinawo.

(2) Kufunika kodalirika kwambiri. Pakadali pano, makina amagetsi a PV amagwiritsidwa ntchito kwambiri m'madera akutali, malo ambiri opangira magetsi ndi opanda anthu komanso osamalidwa, zomwe zimafuna kuti inverter ikhale ndi dongosolo loyenera la dera, kuyang'anira bwino zigawo zake, ndipo imafuna kuti inverter ikhale ndi ntchito zosiyanasiyana zoteteza, monga: chitetezo cha DC polarity reversal, chitetezo cha AC output short-circuit, kutentha kwambiri, chitetezo cha overload ndi zina zotero.

(3) Amafuna mphamvu zambiri zosinthira mphamvu yamagetsi yolowera. Pamene mphamvu yamagetsi ya selo la dzuwa imasintha malinga ndi mphamvu ya mphamvu ya dzuwa ndi katundu wake. Makamaka pamene batire ikukalamba mphamvu yake yamagetsi imasintha pamlingo waukulu, monga batire ya 12V, mphamvu yake yamagetsi imatha kusiyana pakati pa 10V ~ 16V, zomwe zimafuna kuti inverter ikhale ndi mphamvu zambiri zolowera mphamvu yamagetsi ya DC kuti iwonetsetse kuti ikugwira ntchito bwino.

Gulu la Inverter

Yokhazikika, Yachingwe, Yogawidwa ndi Yaing'ono.

Malinga ndi miyeso yosiyanasiyana monga njira yaukadaulo, kuchuluka kwa magawo a mphamvu ya AC yotuluka, kusungirako mphamvu kapena ayi, ndi madera ogwiritsira ntchito pansi, ma inverter anu adzagawidwa m'magulu.
1. Malinga ndi kusungirako mphamvu kapena ayi, imagawidwa m'magulu awiri:Inverter yolumikizidwa ndi gridi ya PVndi inverter yosungira mphamvu;
2. Malinga ndi kuchuluka kwa magawo a voteji ya AC yotulutsa, amagawidwa m'ma inverters a gawo limodzi ndima inverter a magawo atatu;
3. Malinga ndi ngati ikugwiritsidwa ntchito mu makina opangira magetsi olumikizidwa ndi gridi kapena kunja kwa gridi, imagawidwa m'magulu a inverter olumikizidwa ndi gridi ndichosinthira magetsi chomwe sichili pa gridi;
5. Malinga ndi mtundu wa mphamvu ya PV yomwe imagwiritsidwa ntchito, imagawidwa m'magulu awiri: inverter yamagetsi ya PV yapakati ndi inverter yamagetsi ya PV yogawidwa;
6. Malinga ndi njira yaukadaulo, ikhoza kugawidwa m'magulu apakati, zingwe, gulu ndima inverter ang'onoang'ono, ndipo njira iyi yogawa magulu imagwiritsidwa ntchito kwambiri.
