Kuri sisitemu ihuza imirasire y'izuba, igihe nikirere bizatera impinduka mumirasire yizuba, kandi voltage kumashanyarazi izahora ihinduka.Kugirango hongerwe ingufu z'amashanyarazi yatanzwe, harebwa ko imirasire y'izuba ishobora gutangwa hamwe n’umusaruro mwinshi iyo izuba ridakomeye kandi rikomeye.Imbaraga, mubisanzwe imbaraga zo kongera imbaraga zongewe kuri inverter kugirango yagure voltage aho ikorera.
Urukurikirane ruto rukurikira rusobanura impamvu ugomba gukoresha imbaraga zo kongera imbaraga, nuburyo uburyo bwo kongera imbaraga zishobora gufasha ingufu zizuba kugirango zongere ingufu z'amashanyarazi.
Kuki Kuzamura Inzira?
Mbere ya byose, reka turebe sisitemu isanzwe ihindura isoko.Igizwe no kuzamura imbaraga zuzunguruka hamwe na inverter umuzenguruko.Hagati ihujwe na bisi ya DC.
Inzira ya inverter ikeneye gukora neza.Bisi ya DC igomba kuba hejuru ya grid voltage ya sisitemu (sisitemu yibice bitatu iruta agaciro kangana numurongo wumurongo wa voltage), kugirango ingufu zishobore gusohoka kuri gride imbere.Mubisanzwe kugirango bikore neza, bisi ya DC muri rusange ihinduka hamwe na gride ya voltage., kugirango urebe neza ko irenze amashanyarazi.
Niba panne ya voltage irenze hejuru ya voltage isabwa ya busbar, inverter izahita ikora, kandi voltage ya MPPT izakomeza gukurikirana kugeza kurwego ntarengwa.Ariko, nyuma yo kugera kuri bisi ya voltage isabwa, ntishobora kugabanuka ukundi, kandi ingingo ntarengwa ntishobora kugerwaho.Ingano ya MPPT ni mike cyane, igabanya cyane ingufu z'amashanyarazi kandi inyungu z'umukoresha ntizishobora kwizerwa.Hagomba rero kubaho uburyo bwo gukemura iki kibazo, kandi injeniyeri bakoresha Boost kuzamura imirongo kugirango babigereho.
Nigute Boost Yongera urugero rwa MPPT kugirango yongere amashanyarazi?
Iyo voltage yikibaho irenze voltage isabwa na busbar, kuzamura booster umuzenguruko uri mumuruhuko, ingufu zishyikirizwa inverter binyuze muri diode yayo, hanyuma inverter ikarangiza MPPT ikurikirana.Nyuma yo kugera kuri voltage isabwa ya busbar, inverter ntishobora gufata.MPPT yakoze.Muri iki gihe, igice cyo kuzamura imbaraga cyafashe MPPT, gikurikirana MPPT, kandi kizamura bisi kugira ngo umenye ingufu zacyo.
Hamwe nogukurikirana kwinshi kwa MPPT, sisitemu ya inverter irashobora kugira uruhare runini mukwongera ingufu zumuriro wizuba mugitondo, igice cya nijoro, nimvura.Nkuko dushobora kubibona mumashusho hepfo, imbaraga-nyayo iragaragara.Teza imbere.
Ni ukubera iki imbaraga nini inverter isanzwe ikoresha imiyoboro myinshi ya Boost kugirango yongere umubare wa MPPT?
Kurugero, sisitemu ya 6kw, buri kimwe cya 3kw kugeza kubisenge bibiri, inverteri ebyiri za MPPT zigomba gutoranywa muriki gihe, kubera ko hari ibintu bibiri byigenga byigenga bikora, izuba rya mugitondo riva riva iburasirazuba, rikagaragarira mu buso A hejuru yizuba , voltage nimbaraga kumurongo A ni muremure, naho B uruhande ruri hasi cyane, kandi nyuma ya saa sita ni ikinyuranyo.Iyo hari itandukaniro hagati ya voltage ebyiri, voltage ntoya igomba kongerwa kugirango igere ingufu muri bisi kandi urebe ko ikora kumashanyarazi ntarengwa.
Impamvu imwe, ahantu h'imisozi miremire igoye cyane, izuba rizakenera imirasire myinshi, bityo rikeneye MPPT yigenga, bityo ingufu ziciriritse kandi ndende, nka 50Kw-80kw inverters muri rusange ni 3-4 yigenga Boost, bakunze kuvuga 3-4 MPPT yigenga.
