Nkhaniyi ifotokoza za kampani yathu ya 250kW-1050kWh Grid-connected Energy Storage System (ESS).Ntchito yonseyi, kuphatikiza kupanga, kukhazikitsa, kutumiza, ndi kugwira ntchito kwanthawi zonse, kunatenga miyezi isanu ndi umodzi.Cholinga cha pulojekitiyi ndikukhazikitsa njira zometa kwambiri komanso kudzaza zigwa kuti achepetse mtengo wamagetsi.Kuonjezera apo, magetsi aliwonse owonjezera omwe apangidwa adzagulitsidwanso ku gridi, zomwe zimapangitsa ndalama zowonjezera.Makasitomala adawonetsa kukhutitsidwa kwakukulu ndi yankho lazinthu ndi ntchito zathu.
Gulu lathu lolumikizidwa ndi Grid ESS System ndi yankho logwirizana lomwe limapereka mphamvu zodalirika komanso zogwira ntchito zosungira mphamvu.Imapereka kuphatikiza kopanda msoko ndi gululi, kulola kuwongolera koyenera komanso kugwiritsa ntchito masiyanidwe amitengo yachigwa chapamwamba malinga ndi mfundo zamitengo ya gridi yachigawo.
Dongosololi lili ndi magawo osiyanasiyana, kuphatikiza mabatire a lithiamu iron phosphate, makina owongolera ma batri, ma inverters osungira mphamvu osungira mphamvu, makina oletsa moto wa gasi, ndi machitidwe owongolera zachilengedwe.Ma subsystem awa amaphatikizidwa mwanzeru mkati mwa chidebe chokhazikika chotumizira, ndikupangitsa kuti ikhale yosunthika komanso yoyenera kugwiritsa ntchito zosiyanasiyana.
Zina zodziwika bwino za ESS System yolumikizidwa ndi Grid ndikuphatikiza:
● Kulumikizana kwa gridi molunjika, kumathandizira kuyankhidwa kwamphamvu pakusintha kwamphamvu kwamagetsi ndi kusiyanasiyana kwamitengo yamsika.
● Kuchita bwino kwachuma, kupangitsa kuti ndalama zitheke bwino komanso nthawi yobweza ndalama.
● Kuzindikira zolakwika ndi njira zoyankhira mwachangu kuti zitsimikizire chitetezo chogwira ntchito kwa nthawi yayitali.
● Mawonekedwe a modular amalola kukulitsa kwamphamvu kwa mayunitsi a batire ndi ma inverter osungira mphamvu ziwiri.
● Kuwerengera nthawi yeniyeni yogwiritsira ntchito magetsi ndi kukhathamiritsa mtengo malinga ndi ndondomeko zamitengo ya gridi yachigawo.
● Njira yokhazikitsira uinjiniya wosavuta, zomwe zimapangitsa kuti pakhale zotsika mtengo zogwirira ntchito ndi kukonza.
● Zoyenera kuwongolera katundu kuti achepetse ndalama zamagetsi zamabizinesi.
● Yoyenera kuwongolera katundu wa gridi ndi kukhazikika kwa katundu wopanga.
Pomaliza, ESS System yolumikizidwa ndi Grid ndi njira yodalirika komanso yosunthika yomwe yalandira kutamandidwa kwakukulu kuchokera kwa makasitomala okhutitsidwa.Mapangidwe ake athunthu, kuphatikiza kopanda msoko, komanso kugwira ntchito moyenera kumapangitsa kuti ikhale yamtengo wapatali pamafakitale ndi ntchito zosiyanasiyana.

Chiyambi cha Kuwongolera kwa Container Energy Storage System
3.1 Dziko lothamanga
Makina osungira magetsiwa amagawa magwiridwe antchito a batri m'magawo asanu ndi limodzi: kulipiritsa, kutulutsa, kukhazikika, kulakwitsa, kukonza, ndi DC automatic grid network.
3.2 Kulipira ndi kutulutsa
Dongosolo losungiramo mphamvuli limatha kulandira njira zotumizira kuchokera papulatifomu yapakati, ndipo njirazi zimaphatikizidwa ndikuphatikizidwa mugawo lowongolera.Popanda njira zatsopano zotumizira zomwe zikulandiridwa, dongosololi lidzatsata njira yomwe ilipo kuti ayambe kulipira kapena kutulutsa ntchito.
3.3 Kukhala wopanda kanthu
Makina osungira mphamvu akalowa m'malo okonzeka osagwira ntchito, chowongolera champhamvu cha bidirectional flow and system management management system ikhoza kukhazikitsidwa kukhala standby mode kuti muchepetse kugwiritsa ntchito mphamvu.
3.4 Mabatire amalumikizidwa ku gridi
Dongosolo losungiramo magetsi ili limapereka magwiridwe antchito amtundu wa DC wolumikizira.Pakakhala kusiyana kwa voteji kupitilira mtengo wokhazikitsidwa mkati mwa paketi ya batri, kumalepheretsa kulumikizana kwa gululi molunjika kwa paketi ya batri yokhala ndi kusiyana kwakukulu kwa voteji potseka olumikizirana nawo.Ogwiritsa ntchito amatha kulowa mugawo lolumikizana ndi gridi ya DC poyiyambitsa, ndipo makinawo amangomaliza kulumikizana ndi gululi pamapaketi onse a batri okhala ndi ma voltage ofananira, osafunikira kulowererapo pamanja.
3.5 Kutseka kwadzidzidzi
Dongosolo losungiramo mphamvuli limathandizira kutseka kwadzidzidzi kwamanja, ndikutseka mwamphamvu dongosololi pokhudza chizindikiro chotseka chomwe chili kutali ndi mphete yakomweko.
3.6 Ulendo wosefukira
Makina osungira mphamvu akazindikira cholakwika chachikulu, amangochotsa chowotcha mkati mwa PCS ndikupatula gridi yamagetsi.Ngati wophwanya dera akakana kugwira ntchito, dongosololi limatulutsa chizindikiro chaulendo wochuluka kuti apange ulendo wodutsa wozungulira ndikupatula cholakwikacho.
3.7 Kuzimitsa gasi
Njira yosungiramo mphamvu idzayambitsa heptafluoropropane moto wozimitsa moto pamene kutentha kumaposa mtengo wa alamu.

6.1 Mapangidwe Onse a Chotengera
Dongosolo losungirako batire limagwirizana ndi chidebe cha 40-foot chopangidwa ndi chitsulo chosagwira nyengo.Imateteza ku dzimbiri, moto, madzi, fumbi, mantha, kuwala kwa UV, ndi kuba kwa zaka 25.Itha kutetezedwa ndi mabawuti kapena kuwotcherera ndipo imakhala ndi malo oyambira.Zimaphatikizapo chitsime chokonzekera ndikukwaniritsa zofunikira zoyika crane.Chidebecho ndi IP54 chasankhidwa kuti chitetezedwe.
Ma sockets amphamvu amaphatikiza magawo awiri ndi magawo atatu.Chingwe chapansi chiyenera kulumikizidwa musanapereke mphamvu ku socket ya magawo atatu.Soketi iliyonse yosinthira mu nduna ya AC imakhala ndi chotchingira chodziyimira payokha kuti chitetezedwe.
Kabichi ya AC ili ndi magetsi osiyana pa chipangizo chowunikira kulumikizana.Monga magwero amagetsi osunga zobwezeretsera, imakhala ndi gawo limodzi la magawo atatu lamawaya anayi ndi ma breaker atatu agawo limodzi.Kapangidwe kameneka kamatsimikizira mphamvu yamagetsi ya magawo atatu.
6.2 Ntchito yomanga nyumba
Chitsulo cha chidebecho chidzamangidwa pogwiritsa ntchito mbale zachitsulo za Corten A zolimbana ndi nyengo.Dongosolo loteteza dzimbiri lili ndi choyambira chokhala ndi zinc, chotsatiridwa ndi utoto wa epoxy pakati, ndi utoto wa acrylic kunja.Chimango chapansi chidzakutidwa ndi utoto wa asphalt.
Chigoba cha chidebecho chimakhala ndi zigawo ziwiri zazitsulo zachitsulo, zodzaza ndi ubweya wa rock wosagwira moto wa Gulu A pakati.Zinthu zodzaza ndi ubweya wa mwala sizimangopereka kukana moto komanso zimakhala ndi zinthu zopanda madzi.Makulidwe odzaza padenga ndi makoma am'mbali sayenera kuchepera 50mm, pomwe makulidwe odzaza pansi sayenera kuchepera 100mm.
Mkati mwa chidebecho mudzapakidwa utoto wochuluka wa zinc (wokhala ndi makulidwe a 25μm) wotsatiridwa ndi utoto wa utoto wa epoxy (wokhala ndi makulidwe a 50μm), zomwe zimapangitsa kuti filimu yonse ya utoto ikhale yosachepera 75μm.Kumbali inayi, kunja kudzakhala ndi chiyambi cholemera cha zinc (ndi makulidwe a 30μm) ndikutsatiridwa ndi utoto wa epoxy resin (wokhala ndi makulidwe a 40μm) ndikumalizidwa ndi utoto wopaka utoto wa mphira wa acrylic (wokhala ndi makulidwe). wa 40μm), zomwe zimapangitsa kuti makulidwe a filimu ya utoto osachepera 110μm.
6.3 Mtundu wa Container ndi LOG
Zotengera zonse za zida zoperekedwa ndi kampani yathu zimapopera mbewuzo molingana ndi zipatso zapamwamba kwambiri zotsimikiziridwa ndi wogula.Mtundu ndi LOGO ya zida zotengera zida zimasinthidwa malinga ndi zomwe wogula akufuna.
