Ikariso, bizwi kandi nka grid-ihujweinvertercyangwa ibikorwa-bifatikainverter, gira uruhare runini mukworohereza kwinjiza ingufu zishobora kubaho muri gride ihari.Ikoranabuhanga ryabo rishya rihindura neza amashanyarazi (DC) yakozwe na sisitemu yingufu zishobora kongera ingufu nka panneaux solaire cyangwa turbine yumuyaga mukindi gisimburana (AC) gishobora kugarurwa kuri gride.
Ihame ryibanze ryakazi rya gride-ihujweinverterizenguruka muguhuza imbaraga zabyaye hamwe na frequency na voltage ya gride.Uku guhuza ni ingenzi cyane kugirango habeho ingufu zidasubirwaho muri gride, guhindura amazu nubucuruzi mumashanyarazi mato.Reka turebe neza ibyiciro nibigize uruhare muriki gikorwa cyo guhanga udushya.
1. DC kuri AC ihinduka: Icyiciro cya mbere cya gride-ihujweinverterimikorere nuguhindura ingufu za DC zitangwa ningufu zishobora kongera ingufu muri AC power.Ibi bigerwaho hifashishijwe imiyoboro ya elegitoronike ikoresha imirongo myinshi ihinduranya kugirango ihindure imbaraga kandi itange sine imiraba isa na grid frequency.
2. Ikigereranyo ntarengwa cya Power Point (MPPT): Kuri sisitemu yifoto yizuba, tekinoroji ya MPPT ikoreshwa mugutezimbere ingufu zamashanyarazi.MPPT algorithm ikurikirana ingufu ntarengwa zumuriro wizuba, zemeza koinverterikora neza cyane no mubihe bitandukanye byizuba.
3. Guhuza hamwe na grid parameter: Imbaraga za DC zimaze guhinduka imbaraga za AC, gride-ihujweinverterguhuza inshuro na voltage yingufu za AC zabyaye hamwe na grid parameter.Ibi bigerwaho hifashishijwe uburyo bunoze bwo kugenzura algorithms zihora zikurikirana inshuro na voltage ya gride kandi igahindurainverterIbisohoka.
4. Kurinda birwa birwa: Bihujwe na grideinverterzifite ibikoresho byo kwirinda birwa birinda gukumira urushinge rwamashanyarazi mugihe cyamakosa ya gride cyangwa ibikorwa byo kubungabunga.Izi ngamba zitandukanya uinverteruhereye kuri gride, irinde ingaruka zishobora kuba nkibitekerezo, kandi urebe umutekano wabakozi bakora.
5. Ubwiza bwimbaraga nubugenzuzi bwimbaraga: Grid-ihuzainverterIrashobora kandi kugumana ubuziranenge bwimbaraga mugucunga neza imbaraga zidasanzwe, voltage hamwe nubwuzuzanye.Barashobora gutera inshinge cyangwa gukuramo imbaraga zidasanzwe kugirango bishyure ihindagurika rya voltage kandi bongere imbaraga kandi zizewe za gride.
6. Imirire ya gride-in: Iyo gride ihujweinverterni ihujwe na gride kandi ikemeza kubahiriza ibisabwa byose bya tekiniki, imbaraga za AC zahinduwe zisubizwa kuri gride.Izi mbaraga zirashobora gukoreshwa nabaguzi hafi cyangwa zoherezwa ahantu kure binyuze mubikorwa remezo bihari.
Ihame ryakazi rya gride-ihujweinverterihindura uburyo sisitemu yingufu zishobora kwinjizwa muri gride.Ikoranabuhanga rituma izuba, umuyaga hamwe n’andi masoko y’ingufu zishobora kongera ingufu ku rugero, bikagabanya gushingira ku bicanwa biva mu kirere no kugabanya ibyuka bihumanya ikirere.Byongeye kandiinvertertanga banyiri amazu nubucuruzi amahirwe yo kuba abitabira cyane muguhindura ingufu, gutanga umusanzu wigihe kizaza kandi kirambye.
Muri make, grid-ihujweinverterni urufunguzo rwibanze hagati yingufu zishobora kongera ingufu na gride.Gukora neza kwa DC kuri AC, guhuza hamwe nibintu bya gride hamwe no kurinda ibirwa birinda umutekano wizewe kandi wizewe kwingufu zishobora kongera ingufu mubikorwa remezo bihari.Nka grideinverterikoranabuhanga rikomeje gutera imbere, ihinduka ryimiterere yingufu zisukuye, zirambye zabaye impamo.
