Photovoltaic inverter ntchito mfundo

Mfundo Yogwirira Ntchito
Pakatikati pa chipangizo cha inverter, ndi gawo losinthira ma inverter, lomwe limatchedwa gawo la inverter.Derali limakwaniritsa ntchito ya inverter kudzera pakuwongolera ndi kutseka kwa ma switch amagetsi amagetsi.

Mawonekedwe
(1) Zimafunika kuchita bwino kwambiri.Chifukwa cha mtengo wapamwamba wamakono wa maselo a dzuwa, m'pofunika kuyesa kuwongolera bwino kwa inverter kuti muwonjezere kugwiritsa ntchito ma cell a dzuwa ndikuwongolera magwiridwe antchito.

(2) Kufunika kodalirika kwambiri.Pakali pano, machitidwe opangira magetsi a PV amagwiritsidwa ntchito makamaka kumadera akutali, malo ambiri opangira magetsi sakhala osayendetsedwa ndi kukonzedwa, zomwe zimafuna kuti inverter ikhale ndi dongosolo loyendera dera, kuyang'anitsitsa chigawo chokhwima, ndipo kumafuna kuti inverter ikhale ndi ntchito zosiyanasiyana zotetezera, monga monga: athandizira DC polarity reversal chitetezo, AC linanena bungwe yochepa dera chitetezo, kutenthedwa, chitetezo mochulukira ndi zina zotero.

(3) Pamafunika kusintha osiyanasiyana voteji athandizira.Pamene voteji yotsiriza ya selo ya dzuwa imasintha ndi katundu ndi kuwala kwa dzuwa.Makamaka pamene batire kukalamba voteji ake terminal voteji kusintha osiyanasiyana, monga 12V batire, voteji ake ochiritsira akhoza kusiyana pakati pa 10V ~ 16V, amene amafuna inverter mu osiyanasiyana DC athandizira voteji kuonetsetsa ntchito bwinobwino.

Gulu la Inverter

Centralized, String, Distributed ndi Micro.

Malinga ndi miyeso yosiyanasiyana monga njira yaukadaulo, kuchuluka kwa magawo otulutsa voteji ya AC, kusungirako mphamvu kapena ayi, ndi madera ogwiritsira ntchito kunsi kwa mtsinje, ma inverters anu adzakhala m'magulu.
1. Malingana ndi kusungirako mphamvu kapena ayi, imagawidwaPV grid-yolumikizidwa inverterndi inverter yosungirako mphamvu;
2. Malinga ndi kuchuluka kwa magawo amagetsi a AC, amagawidwa kukhala ma inverters agawo limodzi ndimagawo atatu inverters;
3. Malinga ndi momwe imagwiritsidwira ntchito mumagetsi olumikizidwa ndi gridi kapena opanda gridi, imagawidwa kukhala inverter yolumikizidwa ndi gridi ndioff-grid inverter;
5. malinga ndi mtundu wa PV mphamvu m'badwo ntchito, iwo anawagawa chapakati PV mphamvu inverter ndi kugawira PV mphamvu inverter;
6. molingana ndi njira yaukadaulo, imatha kugawidwa pakati, chingwe, masango ndima micro inverters, ndipo njira yogawa iyi imagwiritsidwa ntchito kwambiri.
