Inverter ya Microgrid eya 30kW–500kW
30kW–500kW Microgrid Hybrid Inverter ye nkola ekwatagana n’ekintu ekiyambako mu pulojekiti z’okutereka amaanyi ga bbaatule za Polinovel, ekoleddwa okutereka amasannyalaze g’enjuba-plus-, amasannyalaze agatali ga -grid, dizero hybrid, n’okukozesa emikutu enafu-grid. Ewagira emirimu egy’okukwasaganya okuyita mu PV input, okutereka bbaatule, okuyunga grid, okukola dizero generator, n’okugabira amasannyalaze aga backup.
Nga erina emirimu gya MPPT, transformer, STS, ne maintenance bypass ezigatta, microgrid hybrid inverter eno eyamba okwanguyiza ensengeka y’enkola n’okukendeeza ku kukwatagana kw’ebitundu eby’ebweru. Kisaanira ebirombe ebyesudde, ebizinga, faamu, ebyalo, C&I microgrids, ne pulojekiti endala nga kyetaagisa okukyusa amasannyalaze mu ngeri ennywevu n’okusindika amasannyalaze mu ngeri ekyukakyuka.
Elongooseddwa okusinziira ku byetaago byo eby’amaanyi
Enteekateeka y’amasannyalaze ag’omugatte (integrated Hybrid Power Design).
Inverter eno eya microgrid hybrid egatta emirimu gya MPPT, transformer, STS, ne maintenance bypass okwanguyiza ensengeka y’enkola ya PV + BESS + diesel hybrid. Kiyamba okukendeeza ku kukwatagana kw’ebitundu eby’enjawulo era kiwagira okuteekebwa mu nkola obulungi kwa pulojekiti ku nkola z’amasoboza g’omukutu ogw’ewala n’enafu-.
Transformer eyawula eyawula oludda lwa DC ya battery okuva ku ludda lw’okusaasaanya AC, era bypass y’okuddaabiriza esobozesa omugugu okusigala nga gulina amaanyi okuva ku grid nga inverter ekolebwako service - ekyetaagisa eky’omugaso mu bifo eddirisa eriggalawo we lizibu okufuna.
Ensengeka ya PV ne Battery ezikyukakyuka
Nga tulina tekinologiya wa MPPT step-up/down, inverter ewagira okukwatagana kw’obusobozi bwa PV obukyukakyuka ku pulojekiti ez’enjawulo ez’okutereka enjuba-plus-. Kiyinza okutegekebwa okusinziira ku busobozi bwa PV, voltage ya bbaatule, obwetaavu bw’omugugu, n’embeera y’ekifo, ekigifuula esaanira okukozesebwa mu microgrid ez’enjawulo.
Eddirisa lya 250–1000 V MPPT likkiriza emiguwa emimpi ku busolya obuziyiziddwa wamu n'emiguwa egy'obuwanvu obujjuvu-ku nsengekera eziteekeddwa ku ttaka. Okusinziira ku mulembe, modulo za MPPT 1 ku 10 ziriwo, era amaanyi ga PV agasinga obunene gatuuka ku kW 825 ku yuniti ya kW 500 - okusobozesa PV okusukkiridde obunene awali obutangaavu bwa sizoni oba nga array eriisa byombi omugugu n’ebbaatule ya vvulovumenti eya waggulu-mu ssaawa ze zimu ez’omusana.
Enkola eyesigika Off-Grid Microgrid
Inverter ewagira emigugu egitali gya bbalansi 100% n’okuyungibwa okukwatagana kwa yuniti eziwera, okuyamba okulongoosa okutebenkera kw’enkola mu mbeera ezitali -grid ne weak-grid. Kisaanira okukozesebwa ng’ebifo eby’okusima eby’obugagga eby’omu ttaka, ebizinga, ennimiro z’abatambuze, n’ebyalo ebitaliiko masannyalaze manywevu.
Obusobozi bw’okutikka obujjuvu obutali bbalansi-bukulu buli wa buli -feeders ezigabibwa mu ngeri etaali ya kyenkanyi mu mitendera esatu, nga eno y’embeera eya bulijjo mu mikutu gy’ebyalo n’obukiiko obugaba enkambi. Off-grid overload capacity is 110% continuous ate 120% okumala eddakiika emu, kiwa headroom eri motor okutandika ku pumps, compressors ne conveyors.
Okulongoosa Amafuta ga Jenereta ya Dizero
Ku microgrids za bbaatule za solar-diesel-battery, DG load rate control eyamba okukwasaganya ebifulumizibwa generator n'okukola PV, okutereka battery, n'obwetaavu bw'omugugu. Kino kiyinza okulongoosa okukendeeza ku mafuta n’okukendeeza ku budde bwa jenereta za dizero eziteetaagisa mu pulojekiti z’amasannyalaze ag’omugatte.
Okukwata jenereta waggulu w’omutindo gw’omugugu gwayo ogusinga obutono ogusemba kyewala okugiteeka mu mazzi n’omuwendo gw’okuddaabiriza ogugigoberera, ate bbaatule enywa entuuyo z’omugugu ennyimpi eziyinza okuwaliriza genset eyookubiri okutandika.

System Topology: Engeri PV, Battery, Grid ne Diesel Generator gye zikolaganamu
Enteekateeka ya layini emu- eya PV + bbaatule + dizero microgrid eya bulijjo ezimbiddwa okwetoloola kabineti emu eya inverter.
PV array ne battery zigabana DC bus, kale surplus solar ecaajinga battery nga tewali mutendera gwa AC ogw’okukyusa AC ogw’omu makkati. Gridi ne jenereta ya dizero biyungibwa ku ludda lwa AC; switch ya static transfer ey’omunda esalawo ensibuko ki ewagira omugugu, era maintenance bypass ekuuma omugugu nga gulina amaanyi okuva ku grid nga gukola service. Awali oludda lw’okutereka nga luweebwa nga enclosure enzijuvu okusinga nga racks, topology y’emu ekola ku ankabineti ey’ebweru BESSoba aBESS erimu ebidomola.
Emitendera gy’okukola
Londa enteekateeka esinga okukukwatako.
Okwekozesa-okwekozesa
PV y’esooka okugabira omugugu; surplus ecaajinga bbaatule mu kifo ky’okugitwala ebweru w’eggwanga. Grid eno ekola ku bbula lyonna.
Okusenya ku ntikko
Battery efulumya waggulu w’omutindo ogwateekebwawo ogw’okuyingiza ebintu mu ggwanga kale obwetaavu obupimiddwa busigala nga buteredde.Okusenya ku ntikkomu budde obutuufu y’enkola esooka ey’okusasula ku muyungiro gwa C&I.
