Ubwoko bwo kubika ingufu zo murugo
Inverteri yo kubika ingufu zo guturamo zirashobora gushyirwa mubice bibiri bya tekiniki: guhuza DC no guhuza AC.Muri sisitemu yo kubika amafoto, ibice bitandukanye nka panneaux solaire nikirahure cya PV, kugenzura, guhinduranya izuba, bateri, imizigo (ibikoresho byamashanyarazi), nibindi bikoresho bikorana.Guhuza AC cyangwa DC bivuga uburyo imirasire y'izuba ihujwe no kubika ingufu cyangwa sisitemu ya batiri.Isano iri hagati yizuba na bateri ya ESS irashobora kuba AC cyangwa DC.Mugihe imiyoboro myinshi ya elegitoronike ikoresha amashanyarazi ataziguye (DC), modules yizuba itanga amashanyarazi ataziguye, kandi bateri yizuba murugo ibika amashanyarazi ataziguye, ibikoresho byinshi bisaba guhinduranya amashanyarazi (AC) kugirango ikore.
Muri sisitemu yo kubika ingufu zikomoka ku mirasire y'izuba, imashanyarazi itaziguye ikomoka ku mirasire y'izuba ibikwa mu ipaki ya batiri ikoresheje umugenzuzi.Byongeye kandi, gride irashobora kandi kwishyuza bateri ikoresheje icyerekezo cya DC-AC.Ingingo yo guhuza ingufu iri kuri bateri ya DC BESS.Ku manywa, amashanyarazi yerekana amashanyarazi abanza gutanga umutwaro (ibikomoka kumashanyarazi yo murugo) hanyuma akishyuza bateri binyuze mumashanyarazi ya MPPT.Sisitemu yo kubika ingufu ihujwe na gride ya leta, ituma ingufu zirenze zigaburirwa muri gride.Mwijoro, bateri isohora kugirango itange ingufu mumitwaro, hamwe nibitagenda neza byuzuzwa na gride.Birakwiye ko tumenya ko bateri ya lithium itanga gusa imbaraga kumitwaro ya gride kandi ntishobora gukoreshwa mumitwaro ihujwe na gride mugihe gride yamashanyarazi.Mubihe aho imbaraga zumutwaro zirenze ingufu za PV, sisitemu yo kubika amashanyarazi hamwe nizuba birashobora gutanga ingufu mumitwaro icyarimwe.Batare igira uruhare runini mu kuringaniza ingufu za sisitemu bitewe n’imihindagurikire y’amashanyarazi y’amashanyarazi no gukoresha amashanyarazi.Byongeye kandi, sisitemu yemerera abakoresha gushiraho igihe cyo kwishyuza no gusohora kugirango babone ibyo bakeneye amashanyarazi.
Uburyo DC Ifatanije Ingufu Zibika Ingufu zikora
Hybrid Photovoltaic + sisitemu yo kubika ingufu
Imirasire y'izuba ivanga hamwe na gride ikora kugirango yongere imikorere yumuriro.Bitandukanye na gride inverter, ihita ihagarika imirasire yizuba mugihe cyumuriro wamashanyarazi kubwimpamvu z'umutekano, inverteri ya Hybrid iha abakoresha ubushobozi bwo gukoresha ingufu ndetse no mugihe cyumwijima, kuko zishobora gukora kuri gride kandi zihujwe na gride.Ibyiza bya Hybrid inverters nuburyo bworoshye bwo gukurikirana ingufu batanga.Abakoresha barashobora kubona byoroshye amakuru yingenzi nkimikorere nimbaraga zitanga ingufu binyuze mumwanya wa inverter cyangwa ibikoresho byubwenge bihujwe.Mugihe aho sisitemu irimo inverter ebyiri, buri imwe igomba gukurikiranwa ukwayo.Ihuriro rya DC rikoreshwa muri Hybrid inverters kugirango igabanye igihombo muguhindura AC-DC.Gukoresha bateri neza hamwe na DC guhuza bishobora kugera kuri 95-99%, ugereranije na 90% hamwe na AC.
Byongeye kandi, imvange ya Hybrid nubukungu, iroroshye, kandi byoroshye kuyishyiraho.Gushyira inverter nshya ya Hybrid hamwe na bateri ya DC ihujwe birashobora kubahenze kuruta guhindura bateri zahujwe na AC muri sisitemu iriho.Imirasire y'izuba ikoreshwa muri inverteri ya Hybrid ntabwo ihenze kuruta imashini ihujwe na gride, mugihe ihererekanyabubasha ridahenze kuruta akabati yo gukwirakwiza amashanyarazi.DC ihuza imirasire y'izuba irashobora kandi guhuza imikorere yo kugenzura no guhinduranya imashini imwe, bikavamo kuzigama byiyongera mubikoresho no gukoresha amafaranga.Uburyo bwiza bwibiciro bya sisitemu ya DC igaragara cyane cyane muri sisitemu yo kubika ingufu za gride na ntoya.Igishushanyo mbonera cya Hybrid inverters itanga uburyo bworoshye bwo kongeramo ibice hamwe nubugenzuzi, hamwe noguhitamo ibice byinyongera ukoresheje DC izuba rihendutse cyane.Hybrid inverters nayo yashizweho kugirango yorohereze guhuza ububiko umwanya uwariwo wose, byoroshe inzira yo kongeramo paki.Sisitemu ya Hybrid inverter irangwa nubunini bwayo bworoshye, gukoresha bateri yumuriro mwinshi, no kugabanya ingano ya kabili, bigatuma igihombo kigabanuka muri rusange.
