I-Utility-Scale Energy Storage Solutions

Isitoreji samandla esikalini esisetshenziswayo noma esikalini segridi sisho izixazululo zesitoreji esikhulu esifakwe ohlangothini lwegridi ukuze kugcinwe ugesi futhi uwukhulule lapho kudingeka. Lawa masistimu ngokuvamile anamandla amakhulu (ngama-megawatts noma ama-gigawatts) futhi aklanyelwe ukubhekana nezikhawu zamandla avuselelekayo, athuthukise ukuqina nokusebenza kahle kwegridi, futhi ahlangabezane nesidingo esikhulu samandla.

Umgomo wokusebenza we-BESS yesilinganiso sokusetshenziswa ungafingqwa njengokukhokhiswa, isitolo, nokukhipha. Lezi zinhlelo zidonsa futhi zigcine amandla ngokuqondile kugridi, emapulazini elanga aseduze, noma eminye imithombo yamandla, futhi akhulule ugesi ngendlela ehlelekile lapho isidingo siphezulu.

Ubude bempilo buncike kukhemistri yebhethri, impilo yomjikelezo, nokonakala kokusebenza. Amabhethri e-lithium-ion—ikakhulukazi i-lithium iron phosphate (LFP)—imvamisa ahlala iminyaka eyi-10–15 ekusetshenzisweni kwesikali segridi, asekela izinkulungwane zemijikelezo yokushaja. Amabhethri e-lead-acid ashibhile kodwa aphila isikhathi esifushane cishe iminyaka engu-5–10 nemijikelezo embalwa.

I-Utility-scale BESS ithuthukisa ukuzinza kwegridi ngokugcina amandla phakathi namahora angasebenzi kakhulu futhi siwakhiphe ngesikhathi sokufunwa okuphezulu. Futhi zisebenza njengamandla okulondoloza athembekile ngesikhathi sezulu esibi kakhulu noma ukuphuma. Ngaphezu kwalokho, zisiza ukulinganisa ukunikezwa kanye nesidingo, ziqinise ukuqina kwegridi, futhi zithuthukise ukusebenza kahle okuphelele.

Iziqukathi ze-BESS ze-Wenergy zihlanganisa amaqoqo ebhethri (namaseli e-Li-ion), i-PDU enamandla kakhulu, i-DC ehlanganisa iKhabhinethi, isistimu yokulawula ukushisa okupholisa uketshezi, kanye nokucindezelwa komlilo okunamazinga amaningi (iphakethe & neleveli ye-aerosol). Idizayini yemojuli isekela 3.44MWh,3.85MWh kuya ku-5.016MWh ukulungiselelwa kweyunithi ngayinye, ethobelana namazinga e-IEC/UL/GB.

I-BESS yesikali esine-containerized utility-scale ye-Wenergy igunyazwe ukuba ibe kumazinga ahamba phambili amazwe ngamazwe nawesifunda, iqinisekisa ukuphepha, ukusebenza, nokuhambisana. Izitifiketi zihlanganisa:

• Izindinganiso zamazwe ngamazwe: UL 1973, UL 9540, UL 9540A (ukuphepha komlilo), IEC 62619, IEC 62933, UN38.3 (ukuphepha kwezokuthutha)
• Izindinganiso zesifunda: CE (EU), GB/T 36276 (China), FCC (North America), kanye namakhodi egridi afana ne-UK G99
• Ukuhlola komuntu wesithathu: TÜV, DNV, nezinye izindikimba zezitifiketi ezaziwa emhlabeni wonke

Lezi zitifiketi ziqinisekisa ukuthi amasistimu ethu ahlangabezana nezidingo zomhlaba jikelele zokuphepha, ukwethembeka, ukusebenzisana kwegridi, nezokuthutha.

Yebo. I-BESS yethu yesikali esisetshenziswayo ifakwe izivikelo eziphelele zokuvikela ukuqinisekisa ukusebenza okuthembekile kwesikhathi eside. Izici zokuphepha ezibalulekile zifaka:

• Ukuvikelwa kwamazinga amathathu: I-BMS yeseli/iphakethe/yeyunithi yezinhlamvu yokushajwa ngokweqile, i-overcurrent, nokuqapha izinga lokushisa
• Ukuvikelwa komlilo: Ukucisha umlilo we-aerosol kabili nge-≤12-imizuzwana yesikhathi sokuphendula kanye nokutholwa okungu-5-in-1 (intuthu, izinga lokushisa, i-hydrogen, i-CO, njll.)
• Ukuphepha kwesakhiwo: Isisekelo esibekezelela amaphutha nge-UL/IEC 62477-1 kanye ne-IP55/IP65 yokuvikela ebiyelwe

I-Wenergy, engomunye wabakhiqizi abahamba phambili bokugcina amabhethri esikalini esisetshenziswayo, iletha izixazululo ezenziwe ngokwezifiso ngokuphelele ezifanelana nemigomo yephrojekthi yakho—kungaba ezokulawula imvamisa, izinsiza zamandla egridi, ukuhlanganisa okuvuselelekayo, ukushefa okuphezulu, noma ukusebenza kwesiqhingi. Ngeminyaka engu-14 yobuchwepheshe bokukhiqiza amabhethri nokusetshenziswa kuzo zonke izimboni ezingu-20+, ithimba lethu lonjiniyela lihlola ubude besikhathi sokukhishwa, isivinini sokuphendula, iphrofayela yokugibela amabhayisikili, kanye nemodeli yemali engenayo ukuze lidizayine uhlelo olungabizi kakhulu noluthembekile.

Iphothifoliyo yethu ye-BESS yesikali segridi isuka ku-1 MWh iye phezu kuka-100 MWh, ehlanganisa ukupholisa uketshezi okuthuthukisiwe, idizayini eneziqukathi ezijwayelekile, ukuhlanganiswa kwesistimu ephezulu, nezinkundla zokulawula ezihlakaniphile. Lokhu kuqinisekisa ukusebenza okuphezulu, ukukala okulula, nokuhambisana ngokugcwele nezidingo zegridi yomhlaba.

Isisindo: 36T (3.85MWh) / 43T (5.016MWh); ezokuthutha zasolwandle/zomgwaqo (izimvume ezikhethekile ezidingekayo>40T).

Isisekelo: Isisekelo sikakhonkolo se-C30 (1.5x ukuqinisa okungu-5.016MWh).

Isikhala: 6.06m(L)×2.44m(W)×2.9m(H); 20% yokonga umhlaba uma kuqhathaniswa no-3.85MWh.

I-Wenergy igqama phakathi kwezinkampani zokugcina amabhethri ezisetshenziswayo ngokunikeza ukusekelwa okuphelele kwangemuva kokuthengisa. Izinkonzo zethu zihlanganisa:

• Ukuqapha okukude: Ukulandelela ukusebenza okungu-24/7 nge-Wenergy EMS.
• Endaweni: Ochwepheshe abaqinisekisiwe bokusebenzisa/ukunakekela.
• Izipele: Isitokwe somhlaba wonke sezingxenye ezibucayi (ama-PDU, amayunithi okupholisa).
