I- Isikhokelo sokukhetha i-ESS yorhwebo Iquka uphicotho-zincwadi lomthwalo jikelele. Kwi-mall, yahlula imfuno ebhalwe yimitha yokuhlawulisa ngexesha lokuxinana kwangokuhlwa. I-EPC kufuneka iqinisekise i-AC bus, ukuhamba kwicala omabini, ukubalwa komthwalo kunye nokhuseleko.
Khetha i-KRL-B261L kwi-120 kW Common-Area Peak.
Umzekelo wemitha yomnini-ndawo unentswela-manani eyi-120 kW. Chaza iklasi ye-B261L kuqala. KRL-B261L uzisa 125 kW AC, amandla aqikelelweyo angama-261 kWh, i-189 A njengomsinga ophezulu, iibhetri ezipholiswa ngulwelo kunye ne-120 kW njengengena ephezulu ye-direct-PV. kwiimveliso ezimbini ezichaziweyo. Oku kuyahlangabezana nesikrini samandla sokuqala ngaphandle kokuzibophelela kudidi olukhulu lwe-250 kW.
| Ikhefu | Imfuno yesiza | Amandla ebhetri ayafuneka | Amandla e-AC ayafuneka |
|---|---|---|---|
| 17:30–18:00 | 280 kW | I-100 kW | Amashumi amahlanu e-kWh |
| 18:00–18:30 | 300 kW | 120 kW | Amashumi amathandathu e-kWh |
| 18:30–19:00 | 280 kW | I-100 kW | Amashumi amahlanu e-kWh |
| Zizonke | — | 120 kW elona liphezulu | 160 kWh |
I-160 kWh yamandla e-AC ahanjisiweyo sisango lesibini lokuthenga. B261L’s 261 kWh is rated battery energy, so the usable SOC window, losses, cooling auxiliaries and any backup reserve must still leave at least 160 kWh at the agreed meter. The buyer gets a clear two-part equipment decision: a 125 kW converter class and a documented evening energy target.
Ukuthenga i-B261L kulo msebenzi kugcina uyilo lukwikhabhathi enye ye-125 kW endaweni yokucinga ukuba wonke umcimbi wokuthengisa ufuna iyunithi ye-250 kW. Ulongo lweendleko zezixhobo alunakuchazwa de kuthelekiswe iikowuteshini ezimbini ezifakelweyo.
Chaza i-KRL-B522L kwi-240 kW ye-Shared-Meter Peak.
I-mitha enkulu ekwabelwana ngayo ebonisa i-420 kW xa imfuneko ejoliswe kuyo iyi-180 kW. 240 kW yokukhupha kwebhetri. Oda uyilo lweklasi ye-B522L, hayi i-B261L enye. KRL-B522L unikezela Iguquleli ye-AC eyi-250 kW, ibhetri elinganiselwe kwi-522 kWh, umsinga ophezulu we-AC oyi-375 A kunye nokupholisa okwenzeka ngokutshiza ulwelo. kwikhabhathi enye. I-KRL ikwapapasha ukusebenza ngokunxuseneyo kweeyunithi ezifikelela kwezintandathu kwiidizayini zeenkqubo zexesha elizayo.
| Ubude obuphezulu | Amandla aceliweyo kwicala le-AC, phambi kwezibonelelo zoyilo. |
|---|---|
| Imizuzu engamashumi amathathu | 120 kWh |
| Imizuzu engamashumi amathandathu | 240 kWh |
| Imizuzu engamashumi alithoba | 360 kWh |
| Imizuzu elikhulu namashumi amabini | 480 kWh |
A 90-minute block demands 360 kWh delivered at the AC measurement point. Battery-side energy must be higher after conversion losses, and any protected reserve reduces the available discharge window. B522L’s rated 522 kWh makes it a credible starting class, but delivered AC energy still has to be checked at the agreed meter and battery condition.
I-B522L ibeka umthwalo we-240 kW kwi-converter enye ye-AC eyi-250 kW., kunye Amandla aqikelelwe kwi-522 kWh kunye ne Umda wamandla avela kwi-PV angama-240 kW. Those figures double B261L’s published rated energy and PV-input power. For a shared-meter mall, the result is one larger power block, a longer energy-design starting point and a larger possible direct-PV interface.
Sebenzisa i-Rooftop PV ukuzalisa ibhetri, hayi ukwenza umbane wangokuhlwa.
The mall’s roof can charge the battery during the day. Evening shoppers and food-court loads may remain high after solar production falls; the discharge plan must use the PV output actually present at that hour. An after-sunset peak can require the whole power gap from KRL’s AC converter.
Ukuba isikhululo esikhulu sinezinto eziseleyo zamandla asebenzisekayo emini, loo mandla anokutshaja ibhetri ye-KRL phambi kokuxinana kwangokuhlwa. I-B261L iyapapasha 120 kW elona nani liphezulu lokufakwa kwe-PV kwaye i-B522L ipapasha 240 kW elona nani liphezulu lokufakwa kwe-PV. Ezi zii Imida yokufaka ye-PV, hayi izongezo kwinqanaba lokuphuma kwe-AC eliyi-125 kW okanye 250 kW.
Inkunkuma I-80 kW yamandla elanga agqithisileyo ahlala iiyure ezimbini ibonelela nge-160 kWh phambi kokulahleka kolwelo.. It cannot by itself restore the example’s 160 kWh of delivered AC discharge. A 300 kW rooftop output serving 250 kW of simultaneous mall load leaves only 50 kW for charging. Existing AC-coupled PV needs an approved electrical and controls design; its inverter output cannot be treated as power entering a cabinet’s dedicated DC PV port.
KRL’s liquid-cooling comparison Ichaza isakhiwo solawulo lobushushu sekhabhinethi. Ukupholisa ngokwamanzi kuxhasa ukukhethwa kwezixhobo; akuqinisekisi isantya sokutshaja okanye inani lamandla asetyenzisiweyo elingangqinwanga yimodeli esebenzayo.
Bonisa umnini ukuba yeyiphi intlawulo yombane enokutshintsha ngokwenene.
The business case should follow the shopping mall’s tariff and meter arrangement. Demand charges may depend on the highest measured interval, contracted capacity or another local billing rule. Some charges are fixed, and independently billed tenants may not share the landlord’s demand-charge benefit.
Umzekelo wokubala i-tariff ye-USD, asiyomphumo weprojekthi ye-KRL: ukuba intlawulo yesidingo esisebenzayo y $15 nge-kW-nyanga kwaye elona nani liphezulu lenyanga elibhalisiweyo liyehla nge 120 kW, icandelo layo leentlawulo zizonke zomrhumo wokufuna liyehla nge $1,800 ngenyanga leyo. Esi asisosithembiso sokonga. Umgaqo wokwenene wokubiza ngokwesidingo, ukutshajwa kwakhona kombane, iilahleko kunye neendleko zofakelo zinqumla isiphumo sezemali.
Uphononongo lwetyala lwendawo yokuthenga lwangoMatshi 2024 oluvela kwi-Energy Toolbase lubhala ngokusetyenziswa kweli shishini kusetyenziswa ugcino lwe-Socomec kunye ne-EMS yokugcina njengomthombo wesibini kunye nolawulo lwemfuno. Oku kunceda ekungqineni ukufaneleka kwayo kwimarike, kodwa hayi a KRL installation or a forecast for this mall. The KRL purchase case is established from this mall’s bill, peak records and the B261L/B522L ratings.
Khetha phakathi kwekhabhathi enye i-B522L nezimbini i-B261L
Iikhabhathi ezimbini ze-B261L zenza 250 kW / 522 kWh umthamo oqhelekileyo, ehambelana ne-B522L enye ephepheni. Azifakwanga ngokufanayo. I-B522L enye ibeka udidi lwe-250 kW kwi-converter enye kunye ne-a 375 A indlela yesixhobo; iiyunithi ezimbini ze-B261L zenza iibhloko ezimbini zoguqulo ze-125 kW nge 189 Umbane ophezulu we-AC ngekhabhinethi nganye, kwaye iingeni zazo ze-PV kunye neendibaniso zazo kufuneka zicwangciswe ngokwahlukeneyo.
Specify one B522L for the example’s 240 kW block on a suitable common bus. Iiyunithi ezimbini ze-B261L zilungele ababoneleli abazimeleyo abakwizinga elithile okanye ufakelo olwahlulweyo xa uyilo lonxibelelwano kunye nokusebenza ngokunxuseneyo kuvunyiwe. Ezikhoyo Uthelekiso lwe-KRL yee-khabhinethi ezimbini neye-khabhinethi enye Iquka ikhebula, ipadi kunye neenkcukacha zofakelo.
Gcina i-Backup Kuphela Emva Kokuba Ukwabiwa Kwamandla Aphezulu Kumiselwe
Abanini-ziko lezorhwebo basenokufuna ukuba izibane ezibalulekileyo, iinkqubo zentlawulo, izixhobo zokupholisa okanye izilawuli zihlale zinombane ngexesha lokunqamka kombane. Loo nto lulwalamlo olwahlukileyo lombane namandla. Ikhabhathi ekhupha i-360 kWh ngexesha lokusetyenziswa kakhulu ngokuhlwa ayinakuthembisa loo 360 kWh kwakhona ngexesha lokunqamka kombane ebusuku ngaphandle kokuba iyitshaje kwakhona.
Khetha umsebenzi ophambili phambi kokuthengisa iziphumo zombini. Ukuba i-backup iyimfuneko, gcina amandla ayo aqinisekisiweyo nasebenzisekayo uze ushiye kuphela intsalela ekhoyo ukunciphisa incopho yangokuhlwa. Inkonzo engaphandle kwegridi ikwafuna ibhasi yomthwalo obalulekileyo evunyiweyo, ulungiselelo lokutshintshela, uyilo lokhuseleko kunye nophononongo lokuqalisa kwakhona. Inani elipapashiweyo lokutshintshela elingaphantsi kwe-10 ms leekhabhathi ze-KRL asilulo qinisekiso elibanzi lokuba yonke indawo yentengiso, kuquka zonke ii-escalator kunye nee-chiller, iza kutshintshela ngaphandle kokuphazamiseka.
I- Isikhokelo se-KRL sokunciphisa i-peak kunye nokwabela i-backup Ichaza indlela amandla agciniweyo afanayo anokwabelwa imisebenzi eyahlukeneyo.
Yandisa i-KRL System xa iMall yongeza umthwalo ongaphezulu okanye iiyure ezongezelelweyo zokusebenza
A new cinema wing, food court or fast-charging area can change the peak’s height, duration or both. Recalculate on the same relevant meter and confirm the electrical bus before adding capacity. KRL lists B522L for ukuya kutsho kwizixhobo ezithandathu ezisebenza ngokunxuseneyo Kuxhomekeke kuyilo lwenkqubo; isikrini sokuqala sekhabhathi enkulu ngaphezulu kwe-250 kW yokunqongophala kwamandla sinokuba ziiyunithi ezimbini ze-B522L.
Xa iifeder ezininzi okanye iprojekthi yesikali-somzi-mveliso inyusa umthwalo ukuya kutsho kwi-750 kW okanye i-1 MW, vavanya ukucwangciswa kwe-container okuchanekileyo kunye nofakelo lwaselayithini, kunokuba uqokelele iikhabhathi ngokuzenzekelayo. Uthelekiso lweklasi ye-KRL 750 kW / 1 MW Ibonisa ezo nkethho zikwinqanaba lesityalo.
Ibhetri enkulu ayinakulungisa umthwalo onamandla ombane oselula imihla ngemihla, edlula amandla ombane akhoyo kwinethiwekhi nakwimveliso. Ugcino lwatshintsha unikezelo lweeyure; amandla ombane kufuneka abuyiselwe.
