Imirasire y'izuba

Inverteri ya Photovoltaque (PV inverter cyangwa izuba riva) irashobora guhindura imbaraga za voltage ya DC itangwa na panneaux solaire ya Photovoltaque (PV) ihinduka inverter hamwe nubundi buryo bwo guhinduranya amashanyarazi (AC) inshuro nyinshi, zishobora kugarurwa muri sisitemu yohereza amashanyarazi mubucuruzi, cyangwa itangwa kuri gride ikoreshwa rya gride.Inverteri ya Photovoltaque nimwe mubintu byingenzi bingana na sisitemu (BOS) muri sisitemu ya Photovoltaque array, ishobora gukoreshwa hamwe nibikoresho rusange bitanga amashanyarazi.Imirasire y'izuba ifite imikorere yihariye ya fotokoltaque, nka power point ikurikirana no kurinda ikirwa.

Imirasire y'izuba irashobora kugabanywamo ibyiciro bitatu bikurikira:
Guhindura wenyine wenyine:Ikoreshwa muri sisitemu yigenga, umurongo wa Photovoltaque wishyuza bateri, naho inverter ikoresha voltage ya DC ya batiri nkisoko yingufu.Inverters nyinshi yihagararaho nayo irimo charger za batiri zishobora kwaka bateri kumashanyarazi ya AC.Mubisanzwe, inverter ntizikora kuri gride bityo ntizisaba kurinda ikirwa.

Imashini ihuza imashini:Umuvuduko w'amashanyarazi wa inverter urashobora gusubizwa mumashanyarazi ya AC yubucuruzi, bityo sine wave isohoka igomba kuba imwe nicyiciro, inshuro na voltage yumuriro w'amashanyarazi.Imiyoboro ihujwe na gride ifite igishushanyo mbonera cyumutekano, kandi niba idahujwe n’amashanyarazi, ibisohoka bizahita bizimya.Niba ingufu za gride zananiranye, inverter ihuza gride ntabwo ifite umurimo wo gusubiza inyuma amashanyarazi.

Inverteri yinyuma ya bateri (Inverteri yububiko)ni inverter idasanzwe ikoresha bateri nkisoko yimbaraga zayo kandi igafatanya na charger ya bateri kugirango yishyure bateri.Niba hari imbaraga nyinshi, izishyuza amashanyarazi ya AC.Ubu bwoko bwa inverter burashobora gutanga ingufu za AC kumutwaro wagenwe mugihe ingufu za gride zananiranye, bityo rero igomba kugira ibikorwa byo kurinda ikirwa.
Ingingo nyamukuru: Gukurikirana imbaraga ntarengwa
Inverters ya Photovoltaic ikoresha tekinoroji ya Power Point Tracking (MPPT) kugirango ikure ingufu zishoboka zose zituruka kumirasire y'izuba.Hariho isano itoroshye hagati yimirasire yizuba, ubushyuhe hamwe nuburwanya bwuzuye bwingirabuzimafatizo zuba, bityo umusaruro usohoka uzahinduka utari umurongo, ibyo bita umurongo wa voltage umurongo (IV umurongo).Intego yumuriro ntarengwa wo gukurikirana ni ukubyara umutwaro (wa module yizuba) kugirango ubone imbaraga nini ukurikije ibisohoka mumasoko yizuba muri buri bidukikije.
Imiterere yibintu (FF) ya selile yizuba ifatanije numuyoboro wacyo ufunguye (VOC) hamwe numuyoboro mugufi (ISC) bizagena ingufu ntarengwa zingirabuzimafatizo.Imiterere yimiterere isobanurwa nkigipimo cyingufu ntarengwa zingirabuzimafatizo zuba zigabanijwe nibicuruzwa bya VOC na ISC.

Hano hari algorithms eshatu zitandukanye kumpamvu ntarengwa zikurikirana:guhagarika-no-kwitegereza, imyitwarire yiyongera, hamwe na voltage ihoraho.Babiri ba mbere bakunze kwitwa "kuzamuka umusozi".Uburyo nugukurikiza umurongo wa voltage nimbaraga.Niba iguye ibumoso bwumuriro ntarengwa, ongera voltage, kandi niba iguye iburyo bwumuriro ntarengwa, gabanya voltage.

Igenzura ryishyurwa rirashobora gukoreshwa hamwe nimirasire yizuba kimwe nibikoresho bikoreshwa na DC.Umugenzuzi wubwishyu arashobora gutanga ingufu za DC zihamye, akabika ingufu zirenze muri bateri, kandi agakurikirana amafaranga ya bateri kugirango yirinde kwishyuza cyane cyangwa kurenza urugero.Niba hari modules zihenze zishobora kandi gushyigikira MPPT.Inverter irashobora guhuzwa nibisohoka mugucunga izuba, hanyuma inverter irashobora gutwara umutwaro wa AC.
