Lesi sihloko sizokwethula uhlelo lwenkampani yethu oluyi-250kW-1050kWh oluxhumeke kwiGridi Yamandla Esitoreji (ESS).Lonke uhlelo, okuhlanganisa ukuklama, ukufakwa, ukugunyazwa, nokusebenza okuvamile, kwathatha ingqikithi yezinyanga eziyisithupha.Inhloso yale phrojekthi ukusebenzisa amasu okushefa okuphezulu kanye nokugcwalisa izigodi ukuze kwehliswe izindleko zikagesi.Ukwengeza, noma yimuphi ugesi oweqile okhiqizwayo uzothengiswa ubuyiselwe kugridi, kungenise imali eyengeziwe.Ikhasimende lizwakalise ukwaneliseka okuphezulu ngesixazululo somkhiqizo wethu namasevisi.
Uhlelo lwethu lwe-ESS oluxhumeke kuGridi luyisixazululo esiklanyelwe esihlinzeka ngamakhono athembekile nasebenza ngempumelelo okugcina amandla.Inikeza ukuhlanganiswa okungenazihibe negridi, okuvumela ukuphathwa komthwalo okuphelele kanye nokusetshenziswa komehluko wentengo ephakeme kakhulu ngokwemigomo yegridi yesifunda ngayinye.
Uhlelo luhlanganisa izingxenye ezihlukahlukene, okuhlanganisa amabhethri e-lithium iron phosphate, amasistimu okuphatha amabhethri, ama-inverters e-bidirectional okugcinwa kwamandla, amasistimu okucindezela umlilo wegesi, nezinhlelo zokulawula imvelo.Lawa masistimu angaphansi ahlanganiswe ngobuhlakani ngaphakathi kwesiqukathi sokuthumela esimisiwe, okusenza sisebenziseke ngezindlela eziningi futhi silungele uhla olubanzi lwezinhlelo zokusebenza.
Ezinye izinzuzo eziphawulekayo Zohlelo lwethu lwe-ESS oluxhumeke kuGridi zifaka:
● Ukuxhumana kwegridi okuqondile, okusiza ukusabela okuguquguqukayo ekuguquguqukeni komthwalo wamandla kanye nokwehluka kwentengo yemakethe.
● Ukusebenza kahle kwezomnotho okuthuthukisiwe, okuvumela ukwenziwa kwenzuzo okuthuthukisiwe kanye nezikhathi zokukhokha zokutshalwa kwezimali.
● Ukutholwa kwamaphutha okusebenzayo kanye nezindlela zokuphendula ngokushesha ukuze kuqinisekiswe ukuphepha kokusebenza kwesikhathi eside.
● Idizayini ye-modular evumela ukunwetshwa okukhulu kwamayunithi ebhethri kanye neziguquli eziqondiswa kabili zokulondoloza amandla.
● Ukubalwa kwesikhathi sangempela sokusetshenziswa kukagesi nokuthuthukiswa kwezindleko ngokuya ngezinqubomgomo zamanani egridi yesifunda.
● Inqubo yokufaka ubunjiniyela eyenziwe lula, okuholela ekwehleni kwezindleko zokusebenza nezokulungisa.
● Ilungele ukulawulwa komthwalo ukuze kuncishiswe izindleko zikagesi zebhizinisi.
● Ifanele ukulawulwa komthwalo wegridi nokuzinzisa imithwalo yokukhiqiza.
Sengiphetha, Uhlelo lwethu lwe-ESS oluxhumeke kuGridi luyisixazululo esinokwethenjelwa nesisebenza ngezindlela eziningi esithole ukunconywa okuphezulu kumakhasimende ethu anelisekile.Idizayini yayo ebanzi, ukuhlanganiswa okungenamthungo, nokusebenza kahle kuyenza ibe yimpahla ebalulekile yezimboni nezinhlelo zokusebenza ezahlukahlukene.

Isingeniso Sokulawulwa Kohlelo Lwesitoreji Samandla Esitsha
3.1 Isimo sokugijima
Lolu hlelo lokulondoloza amandla luhlukanisa ukusebenza kwebhethri ngezimo eziyisithupha ezihlukene: ukushaja, ukushajwa, ukulungele ukuma, iphutha, ukugcinwa, kanye nezimo zokuxhuma kwegridi okuzenzakalelayo kwe-DC.
3.2 Ukushaja nokukhipha
Lolu hlelo lokugcina amandla luyakwazi ukuthola amasu okuthumela kusuka endaweni emaphakathi, futhi lawa masu abe esehlanganiswa futhi ashumekwe kutheminali yokulawula ukuthunyelwa.Uma engekho amasu amasha okuthumela atholwayo, isistimu izolandela isu lamanje lokuqalisa imisebenzi yokushaja noma yokukhipha.
3.3 Isimo sokungenzi lutho esilungele
Uma isistimu yokulondoloza amandla ingena esimweni sokungenzi lutho esilungile, isilawuli sokugeleza okuphindwe kabili kwamandla kanye nesistimu yokuphatha ibhethri ingasethwa kumodi yokulinda ukuze kuncishiswe ukusetshenziswa kwamandla.
3.4 Ibhethri lixhunywe kugridi
Lolu hlelo lokulondoloza amandla luhlinzeka ngokusebenza okuphelele kokulawula ukuxhumana kwegridi ye-DC.Uma kunomehluko we-voltage owedlula inani elibekiwe ngaphakathi kwephakethe lebhethri, ivimbela ukuxhumana kwegridi eqondile yochungechunge lwephakethe lebhethri elinomehluko wevolthi owedlulele ngokukhiya abathintwayo abahambisanayo.Abasebenzisi bangafaka isimo sokuxhuma kwegridi ye-DC ngokuzenzakalelayo ngokusiqalisa, futhi isistimu izoqedela ngokuzenzakalelayo ukuxhunywa kwegridi yawo wonke amaphakethe ebhethri ochungechunge ngokufanisa i-voltage efanele, ngaphandle kwesidingo sokungenelela okwenziwa ngesandla.
3.5 Ukuvala shaqa okuphuthumayo
Lolu hlelo lokugcina amandla lusekela umsebenzi wokuvala shaqa izimo eziphuthumayo mathupha, futhi luvala ngenkani ukusebenza kwesistimu ngokuthinta isignali yokuvala shaqa efinyelelwa ukude iringi yendawo.
3.6 Uhambo oluchichimayo
Uma isistimu yokugcina amandla ithola iphutha elikhulu, izonqamula ngokuzenzakalelayo isinqamuli sesifunda ngaphakathi kwe-PCS futhi ihlukanise igridi yamandla.Uma i-circuit breaker yenqaba ukusebenza, isistimu izokhipha isignali yohambo oluchichimayo ukwenza uhambo lwe-circuit breaker futhi ihlukanise iphutha.
3.7 Ukucisha igesi
Isistimu yokugcina amandla izoqala isistimu yokucisha umlilo ye-heptafluoropropane lapho izinga lokushisa lidlula inani le-alamu.
4.Incazelo Esebenzayo Yamamojula Esistimu Yokugcina Amandla Esitsha(thintana nathi ukuze uthole imininingwane)
5.Ukuhlanganiswa Kwesistimu Yesitoreji Samandla(xhumana nathi ukuze uthole imininingwane)
6.Umklamo Weziqukathi
6.1 Umklamo Uwonke Wesitsha
Isistimu yokugcina ibhethri ilingana nesiqukathi esingamamitha angu-40 esenziwe ngensimbi engamelana nesimo sezulu.Ivikela ukugqwala, umlilo, amanzi, uthuli, ukushaqeka, imisebe ye-UV, kanye nokwebiwa iminyaka engu-25.Ingavikelwa ngamabhawodi noma nge-welding futhi inamaphuzu okumisa phansi.Ihlanganisa umthombo wokulungisa futhi ihlangabezana nezidingo zokufakwa kwe-crane.Isiqukathi siyi-IP54 sihlukaniswe ukuze sivikeleke.
Amasokhethi amandla ahlanganisa kokubili izinketho zezigaba ezimbili kanye nezigaba ezintathu.Intambo yaphansi kufanele ixhunywe ngaphambi kokunikeza amandla esokhethi yezigaba ezintathu.Isokhethi ngalinye lokushintsha kukhabethe le-AC linesihlukanisi esizimele sokuvikela.
Ikhabhinethi ye-AC inogesi ohlukile wedivayisi yokuqapha ukuxhumana.Njengemithombo yamandla eyisipele, igcina isinqamuli sesifunda esinezintambo ezine ezinezigaba ezintathu kanye nama-breaker circuit amathathu wesigaba esisodwa.Idizayini iqinisekisa umthwalo wamandla wezigaba ezintathu olinganiselayo.
6.2 Ukusebenza kwesakhiwo sezindlu
Isakhiwo sensimbi sesiqukathi sizokwakhiwa kusetshenziswa amapuleti ensimbi amelana nesimo sezulu seCorten A.Isistimu yokuvikela ukugqwala iqukethe i-primer ecebile nge-zinc, elandelwa ungqimba lukapende lwe-epoxy phakathi, kanye nongqimba lukapende lwe-acrylic ngaphandle.Uhlaka olungezansi luzogcotshwa ngopende lwe-asphalt.
Igobolondo lesiqukathi lakhiwe izingqimba ezimbili zamapuleti ensimbi, anento yokugcwalisa yoboya betshe bebanga A ekwazi ukumelana nomlilo phakathi.Le nto yokugcwalisa uboya be-rock ayihlinzeki nje kuphela ukumelana nomlilo kodwa futhi inezindawo ezingenawo amanzi.Ubukhulu bokugcwalisa ophahleni kanye nezindonga eziseceleni kufanele bungabi ngaphansi kuka-50mm, kanti ubukhulu bokugcwalisa phansi akufanele bube ngaphansi kuka-100mm.
Ingaphakathi lesiqukathi lizopendiwa nge-primer ecebile nge-zinc (enogqinsi oluyi-25μm) elandelwa ungqimba lukapende we-epoxy resin (olunogqinsi lwama-50μm), okuholela ekubeni ingqikithi yefilimu kapende ubukhulu obungekho ngaphansi kuka-75μm.Ngakolunye uhlangothi, ingaphandle lizoba ne-primer ecebile nge-zinc (enobukhulu obungama-30μm) elandelwa ungqimba lukapende lwe-epoxy resin (olunogqinsi lwama-40μm) futhi luqede ngopende ongaphezulu werabha we-acrylic owenziwe ngepulasitiki (onogqinsi). ka-40μm), okuholela ekutheni ifilimu kapende ibe nogqinsi olungekho ngaphansi kuka-110μm.
6.3 Umbala wesiqukathi kanye ne-LOGO
Isethi ephelele yeziqukathi zemishini ehlinzekwe yinkampani yethu ifafazwa ngokwenani lezithelo eliphakeme kakhulu eliqinisekiswe umthengi.Umbala kanye ne-LOGO yemishini yesiqukathi kwenziwa ngokwezifiso ngokuya ngezidingo zomthengi.

Phawula:
1. Imali engenayo ibalwa ngokwe-DOD yangempela (90%) yohlelo kanye nokusebenza kahle kwesistimu okungama-86%.
2. Lesi sibalo semali engenayo sibheka kuphela imali engenayo yonyaka yesimo sokuqala sebhethri.Ngesikhathi sokuphila kwesistimu, izinzuzo ziyancipha ngomthamo webhethri otholakalayo.
3, ukonga ngonyaka kugesi ngokusho 365 izinsuku ezimbili icala ukukhululwa ezimbili.
4. Imali engenayo ayicabangi izindleko, Xhumana nathi ukuze uthole intengo yesistimu.
Umkhuba wenzuzo wokushefa okuphezulu kanye nohlelo lokugcina amandla okugcwalisa isigodi uyahlolwa ngokucutshungulwa kokonakala kwebhethri:
