Icyuma gikoresha izuba ni iki?

Imirasire y'izuba yemeza ko amashanyarazi akomoka ku mirasire y'izuba yimurirwa mu bwenge muri bateri mu buryo bukwiranye na chimie ya batiri ndetse n'urwego rwo kwishyuza.Umugenzuzi mwiza azagira ibyiciro byinshi byo kwishyuza algorithm (mubisanzwe ibyiciro 5 cyangwa 6) kandi bitange gahunda zitandukanye kubwoko butandukanye bwa bateri.Ibigezweho, byujuje ubuziranenge bizashyiramo gahunda zihariye za bateri ya Lithium, mugihe moderi nyinshi zishaje cyangwa zihendutse zizagarukira kuri bateri ya AGM, Gel na Wet.Ni ngombwa ko ukoresha progaramu ikwiye kubwoko bwa bateri.

Igenzura ryiza ryizuba rizaba ririmo imiyoboro myinshi yo gukingira ibyuma bya elegitoroniki kugirango irinde bateri, harimo kurinda polarite ihindagurika, kurinda imiyoboro ngufi, kurinda imiyoboro ihindagurika, kurinda ibicuruzwa birenze urugero, kurinda amashanyarazi arenze urugero, no kurinda ubushyuhe bukabije.

Ubwoko bw'imirasire y'izuba

Hariho ubwoko bubiri bwingenzi butanga imirasire yizuba iboneka kumirasire yizuba.Impinduka z'ubugari bwa pulse (PWM) hamwe na Power point Tracking (MPPT).Bose bafite ibyiza byabo nibibi byabo, bivuze ko buri kimwe kibereye mubihe bitandukanye byo gukambika.

Impanuka y'ubugari bwa pulse (PWM)

Pulse Width Modulation (PWM), umugenzuzi afite isano itaziguye hagati yizuba na batiri, kandi ikoresha uburyo bwa "bwihuta bwihuse" kugirango igenzure amafaranga yinjira muri bateri.Ihindura ikomeza gufungura byuzuye kugeza igihe bateri igeze kuri voltage ya sink, icyo gihe icyerekezo gitangira gukingura no gufunga inshuro amagana kumasegonda kugirango ugabanye umuyaga mugihe ugumya voltage ihoraho.

Mubyigisho, ubu bwoko bwihuza bugabanya imikorere yizuba ryumuriro kuko voltage yumurongo wamanutse kugirango ihuze na voltage ya bateri.Nubwo bimeze bityo ariko, kubijyanye nimirasire yizuba yikurikiranya, ingaruka zifatika ni ntoya, kuko mubihe byinshi ingufu za panne nini zingana na 18V gusa (kandi bikagabanuka uko akanama gashyuha), mugihe ingufu za batiri ziba ziri hagati ya 12-13V (AGM) cyangwa 13-14.5V (Litiyumu).

Nubwo igihombo gito mu mikorere, abagenzuzi ba PWM muri rusange bafatwa nkuburyo bwiza bwo guhuza imirasire yizuba.Inyungu z'abashinzwe kugenzura PWM ugereranije na MPPT bagenzi babo ni uburemere buke kandi bwizewe, ibyo bikaba ari ibintu byingenzi bitekerezwaho mugihe ukambitse igihe kinini cyangwa ahantu hitaruye aho serivisi idashobora kuboneka byoroshye kandi birashobora kugorana kubona ubundi buryo bwo kugenzura ibintu.

Ikurikiranwa ry'ingufu ntarengwa (MPPT)

Imbaraga ntarengwa zikurikirana MPPT, umugenzuzi afite ubushobozi bwo guhindura voltage irenze iyindi mashanyarazi mugihe gikwiye.

Umugenzuzi wa MPPT azahora akurikirana voltage yumurongo, uhora uhinduka ukurikije ibintu nkubushyuhe bwibihe, ikirere nikirere cyizuba.Ikoresha voltage yuzuye yikibaho kugirango ibare (ikurikirana) ihuza ryiza rya voltage nubu, hanyuma igabanye voltage kugirango ihuze na voltage yumuriro wa bateri kugirango ishobore gutanga amashanyarazi yinyongera kuri bateri (ibuka power = voltage x current) .

Ariko hariho ubuvumo bwingenzi bugabanya ingaruka zifatika za MPPT kububiko bwizuba.Kugirango ubone inyungu nyazo zitangwa na MPPT mugenzuzi, voltage kumurongo igomba kuba byibura volt 4-5 kurenza voltage yumuriro wa bateri.Urebye ko imirasire y'izuba myinshi ishobora gutwara ifite ingufu zingana na 18-20V, zishobora kugabanuka kugera kuri 15-17V mugihe zishyushye, mugihe bateri nyinshi za AGM ziri hagati ya 12-13V na bateri nyinshi za lithium hagati ya 13-14.5V Muri iki gihe, itandukaniro rya voltage ntabwo rihagije kugirango imikorere ya MPPT igire ingaruka nyayo kumashanyarazi.

Ugereranije nabagenzuzi ba PWM, abagenzuzi ba MPPT bafite ibibi byo kuba baremereye muburemere kandi muri rusange ntibizewe.Kubwiyi mpamvu, hamwe ningaruka zazo nkeya mumashanyarazi, ntuzigera ubona akoreshwa mumifuka yizuba.
