30kW–500kW I-Microgrid Hybrid Inverter
I-30kW–500kW Microgrid Hybrid Inverter iyinketho ehambisanayo yesisetshenziswa sephrojekthi yesitoreji samandla ebhethri ye-Polinovel, edizayinelwe isitoreji selanga-kanye{3}}nokucima{4}}amandla egridi, i-diesel hybrid, -nezinhlelo zokusebenza zegridi ezibuthakathaka. Isekela ukusebenza okudidiyelwe kukho konke okokufaka kwe-PV, isitoreji sebhethri, ukuxhumeka kwegridi, ukusebenza kwejeneretha yedizili, kanye nokunikezwa kwamandla okusekelayo.
Nge-MPPT edidiyelwe, i-transformer, i-STS, nemisebenzi ye-bypass yokulungisa, lesi siguquli se-microgrid hybrid sisiza ukwenza lula ukucushwa kwesistimu nokunciphisa ukufanisa ingxenye yangaphandle. Ilungele izimayini ezikude, iziqhingi, amapulazi, amadolobhana, ama-microgrid e-C&I, namanye amaphrojekthi lapho ukuguqulwa kwamandla okuzinzile kanye nokuthunyelwa kwamandla aguqukayo kuyadingeka.
Kwenzelwe Izidingo Zakho Zamandla
Idizayini Yamandla Ehlanganisiwe Ye-Hybrid
Lesi siguquli se-Microgrid hybrid sihlanganisa i-MPPT, i-transformer, i-STS, kanye nemisebenzi ye-bypass yokulungisa ukwenza lula i-PV + BESS + ukucushwa kwesistimu ye-diesel hybrid. Isiza ukunciphisa ukufaniswa kwengxenye ehlukene futhi isekela ukuthunyelwa kwephrojekthi okusebenza kahle kakhulu kokusebenza okukude nokubuthakathaka{3}}kwegridi yezinhlelo zokusebenza.
Isiguquli sokuhlukanisa sihlukanisa uhlangothi lwebhethri lwe-DC kusukela ohlangothini lokusabalalisa lwe-AC, futhi ukudlula kokulungisa kuvumela umthwalo ukuthi uhlale unamandla kusukela kugridi kuyilapho isiguquli siseviswa - imfuneko engokoqobo kumasayithi lapho iwindi lokuvalwa okunzima ukulithola.
I-PV eguquguqukayo nokucushwa kwebhethri
Ngobuchwepheshe be-MPPT obuguqukayo-abaphezulu/phansi, i-inverter isekela ukufana kwamandla e-PV okuguquguqukayo kumaphrojekthi ahlukene elanga-kanye{2}}nokugcina. Ingacushwa ngokuya ngomthamo we-PV, ububanzi be-voltage yebhethri, isidingo somthwalo, nezimo zesayithi, okuyenza ifaneleke izinhlelo zokusebenza ezihlukahlukene ze-microgrid.
Iwindi le-250–1000 V MPPT lamukela izintambo ezimfishane ophahleni oluboshiwe kanye nezintambo-ezigcwele ezinobude ezindaweni{3}}ezifakwe phansi. Kuye ngemodeli, amamojula angu-1 kuye kwayi-10 e-MPPT ayatholakala, futhi amandla aphezulu e-PV afinyelela ku-825 kW kuyunithi engu-500 kW - okuvumela ukweqisa kwe-PV lapho i-irradiance ingokwesizini noma lapho uhlelo luphakela khona kokubili umthwalo kanyeibhethri-elinamandla kagesi aphezuluphakathi namahora okukhanya afanayo emini.
Okuthembekile Kuvaliwe-Ukusebenza Kwe-Grid Microgrid
I-inverter isekela imithwalo engalinganiseli engu-100% noxhumo oluhambisanayo lwamayunithi amaningi, okusiza ukuthuthukisa ukuzinza kwesistimu -kugridi kanye nezimo ezibuthakathaka{2}}zegridi. Ilungele izicelo ezifana nezindawo zezimayini, iziqhingi, amapulazi ahambahambayo, namadolobhana angenawo ugesi ozinzile.
Amandla okulayisha angalingani ngokuphelele{0}abalulekile noma kunini lapho okuphakelayo{1}}kwesigaba esisodwa kusakazwa ngokungalingani ezigabeni ezintathu, okuyisimo esivamile kumanethiwekhi wendawo kanye namabhodi okusabalalisa amakamu. -Umthamo wokulayisha ngokweqile wegridi uyaqhubeka ngo-110% futhi u-120% umzuzu owodwa, unikeza indawo enkulu yenjini eqala kumaphampu, ama-compressor nama-conveyor.
I-Diesel Generator Fuel Optimization
Kuma-microgrid elanga-ye-diesel{1}}yebhethri, ukulawula izinga lokulayisha kwe-DG kusiza ukuxhumanisa okukhipha ijeneretha ngokukhiqizwa kwe-PV, ukugcinwa kwebhethri, kanye nesidingo sokulayisha. Lokhu kungathuthukisa ukonga kukaphethiloli futhi kunciphise isikhathi esingadingekile sejeneretha kadizili kumaphrojekthi kagesi ayingxubevange.
Ukubamba ijeneretha ngaphezu kwesilinganiso sayo esincane sokulayisha esinconyiwe kugwema ukunqwabelana okumanzi kanye nezindleko zokuyilungisa ezikulandelayo, kuyilapho ibhethri idonsa iziqongo zokulayisha ezimfushane ezingaphoqelela i-genset yesibili ukuthi iqale.

I-System Topology: Isebenza Kanjani I-PV, Ibhethri, Igridi Negenerator Dizili
Ukuhlelwa-komugqa owodwa kwe-PV + ibhethri + ne-diesel microgrid eyakhelwe eduze kwekhabethe elilodwa le-inverter.
Amalungu afanayo e-PV kanye nebhethri abelana ngebhasi le-DC, ngakho-ke i-solar engaphezulu ishaja ibhethri ngaphandle kwesigaba sokuguqula i-AC esimaphakathi. Igridi nejeneretha yedizili ixhuma ohlangothini lwe-AC; iswishi yokudlulisa emile yangaphakathi inquma ukuthi yimuphi umthombo osekela umthwalo, futhi i-bypass yokulungisa igcina umthwalo unamandla ukusuka kugridi ngesikhathi sokusevisa. Lapho uhlangothi lwesitoreji luhlinzekwa njengendawo ebiyelwe ngokuphelele esikhundleni sama-rack, i-topology efanayo iyasebenza ku-iKhabhinethi yangaphandle BESSnoma ai-BESS eneziqukathi.
Izindlela Zokusebenza
Khetha icebo elikufanele kakhulu.
Ukuzidla{0}
I-PV inikeza umthwalo kuqala; i-surplus ishaja ibhethri esikhundleni sokuthi ithekeliswe. Igridi ivala noma yikuphi ukushoda.
Ukushefa okuphezulu
Ibhethri liphuma ngaphezu komkhawulo wokungenisa omisiwe ukuze isidingo esilinganisiwe sihlale siphansi.Ukushefa okuphezulungokuvamile iyindlela yokuqala yokubuyisela ekuxhumekeni kwe-C&I.
Isikhathi-so{1}}sokusebenzisa uguquko
Ukushaja kuhlelelwe-emahoreni entengo ephansi futhi kuzokhishwa ngamahora{1}entengo aphezulu.
Amandla ekhophi yasenqolobaneni
Iswishi yokudlulisa emile ihlukanisa uxhumo lwensiza futhi isiguquli esishintshashintshayo siphinda simise-ibhasi elingu-400 V ukusuka kubhethri ne-PV.
Kuvaliwe-kumsebenzi wegridi
I-inverter yakha igridi ngokwayo, ibambe i-400 V / 50–60 Hz ene-THDu Ngaphansi noma elingana no-1% kumthwalo womugqa futhi Ngaphansi noma elingana no-5% kumthwalo ongaqondile.
I-Dizeli hybrid
Ukulawula izinga lokulayisha kwe-DG kugcina ijeneretha ngaphakathi kwebhendi yayo yokulayisha ephumelelayo; I-PV nebhethri kuthatha okusele futhi kufinyeze isikhathi sokusebenza.
Okubalulekile kwe-PV
I-Solar inikezela ngokulayisha nokushaja ngaphambi kokuthi kubizwe noma yimuphi omunye umthombo, okuwukuthunyelwa okuzenzakalelayo -kumasayithi avinjelwe amafutha.
I-bypass yesondlo
Umthwalo udluliselwa kugridi ngokusebenzisa i-bypass yangaphakathi ukuze inverter ikwazi ukuhlukaniswa ngaphandle kokucinywa kwesayithi.
