Ukuthelekisa i-ESS kunye ne-UPS

Imisebenzi kunye nobukhulu

I-ESS iyafana ekwakhiweni kwe-UPS kodwa iyahluka ekusebenziseni kwayo.Njenge-UPS, i-ESS ibandakanya indlela yokugcina amandla efana neebhetri, izixhobo zokuguqula amandla, umzekelo, ii-inverters, kunye nezinye izinto ezahlukeneyo zombane kunye nolawulo.Ngokungafaniyo ne-UPS, nangona kunjalo, i-ESS inokusebenza ngokuhambelana negridi, ekhokelela kwibhayisekile enkulu yenkqubo kunokuba i-UPS iya kuba nakho.I-ESS inokubambisana ngokubambisana kunye negridi okanye kwimodi yokuzimela, okanye zombini, kuxhomekeke kuhlobo lwenkqubo yokuguqula amandla esetyenzisiweyo.I-ESS inokusebenza njengomsebenzi we-UPS.Njenge-UPS, i-ESS inokuza ngokobukhulu obahlukeneyo ukusuka kwinkqubo encinci yendawo yokuhlala engaphantsi kwe-20 kWh yamandla kwizicelo eziluncedo zisebenzisa iinkqubo zesikhongozeli samandla eemegawatt ezininzi ezineentsimbi ezininzi zebhetri ngaphakathi kwesikhongozeli.

Ukuqulunqwa kweekhemikhali kunye nokhuseleko

Iikhemistri zebhetri eziqhelekileyo ezisetyenziswa kwi-UPS bezisoloko ziziibhetri ze-lead-asidi okanye ze-nickel-cadmium.Ngokungafaniyo ne-UPS, i-BESS isebenzisa ubuchwepheshe obufana neebhetri ze-lithium-ion ukususela ekuqaleni kuba iibhetri ze-lithium-ion zinomsebenzi ongcono womjikelo kunye nobuninzi bamandla obuphezulu, obunokubonelela ngamandla amaninzi kwindawo encinci yomzimba.Iibhetri zeLithium-ion nazo zineemfuno zokulondolozwa ezisezantsi kakhulu kuneteknoloji yebhetri yemveli.Kodwa okwangoku, iibhetri ze-lithium-ion zisetyenziswa kakhulu kwizicelo ze-UPS.

Nangona kunjalo, ingozi enkulu e-Arizona ngo-2019 ebandakanya i-ESS esetyenziswa kwizicelo ezisetyenziswayo ibangele ukwenzakala kakhulu kwabaphenduli bokuqala kwaye yatsala ingqalelo yabachaphazelekayo abahlukeneyo, kubandakanya abalawuli kunye nee-arhente ze-inshurensi.Ukuqinisekisa ukuba le ntsimi ekhulayo ayithintelwa yiziganeko ezikhuselekileyo ezikhuselekileyo, iinkcukacha ezifanelekileyo kunye nemigangatho kufuneka iphuhliswe kwi-ESS.Ukukhuthaza ukuphuhliswa kweenkcukacha ezifanelekileyo zokhuseleko kunye nemigangatho ye-ESS, iSebe lezaMandla lase-US (DOE) liqalise iforum yokuqala yonyaka kwi-ESS Safety and Reliability kwi-2015.

IForam yokuqala ye-DOE ESS ibe negalelo kumthamo omkhulu womsebenzi kwiinkcukacha kunye nemigangatho ye-ESS.Eyona nto iphawulekayo kukuphuhliswa kwe-NEC yeNombolo ye-706 kunye nophuhliso lwe-NFPA 855, umgangatho wokufakelwa kwenkqubo yokugcina amandla emileyo, echaphazela ngokuthe ngqo umgangatho weenkqubo zebhetri ezimileyo kwi-ICC IFC kunye ne-NFPA 1. Namhlanje, i-NEC kunye ne-NFPA 855 banayo iphinde yahlaziywa kwiinguqulelo zika-2023.

Ubume bangoku be-ESS kunye nemigangatho ye-UPS

Injongo yayo yonke imithetho kunye nemisebenzi yophuhliso lwemigangatho kukujongana ngokwaneleyo nokhuseleko lwezi nkqubo.Ngelishwa, imigangatho yangoku idale ukudideka kwishishini.

1.NFPA 855. Uxwebhu oluphambili oluchaphazela ukufakwa kwe-BESS kunye ne-UPS yinguqulelo ka-2020 ye-NFPA 855, uMgangatho woFakelo lweeNkqubo zokuGcinwa kwamandla okuSimayo.I-NFPA 855 ichaza ugcino lwamandla “njengendibano yesixhobo esinye okanye ezingaphezulu ezikwaziyo ukugcina amandla okubonelela ngexa elizayo kwimithwalo yombane yasekhaya, iigridi eziluncedo, okanye inkxaso yegridi.”Le nkcazo ibandakanya izicelo ze-UPS kunye ne-ESS.Ukongezelela, i-NFPA 855 kunye neekhowudi zomlilo zifuna ukuba ii-ESSs zihlolwe kwaye ziqinisekiswe kwi-UL 9540. Nangona kunjalo, i-UL 1778 ibisoloko iyinto eqhelekileyo yokhuseleko lwemveliso ye-UPS.Inkqubo iye yavavanywa ngokuzimeleyo ukuze ihambelane neemfuno ezifanelekileyo zokhuseleko kwaye ixhasa ukufakwa okukhuselekileyo.Ke ngoko, imfuno ye-UL 9540 ibangele ukudideka kwishishini.

2. UL 9540A.I-UL 9540A ifuna ukuqala kwinqanaba lebhetri kunye novavanyo lwenyathelo ngenyathelo de udlule kwinqanaba lofakelo.Ezi mfuno zibangela ukuba iinkqubo ze-UPS zixhomekeke kwimigangatho yokuthengisa ebingafunwa ngaphambili.

3.UL 1973. I-UL 1973 yinkqubo yokhuseleko lwebhetri umgangatho we-ESS kunye ne-UPS.Nangona kunjalo, inguqulo ye-UL 1973-2018 ayibandakanyi izibonelelo zokuvavanya iibhetri ze-lead-acid, eziphinda zibe ngumngeni kwiinkqubo ze-UPS usebenzisa iteknoloji yebhetri yendabuko efana neebhetri ze-lead-acid.

Isishwankathelo

Okwangoku, zombini i-NEC (iKhowudi yoMbane yeSizwe) kunye ne-NFPA 855 icacisa ezi nkcazo.

• Ngokomzekelo, inguqulelo ka-2023 ye-NFPA 855 icacisa ukuba i-lead-acid ethile kunye ne-nickel-cadmium iibhetri (i-600 V okanye ngaphantsi) zidweliswe kwi-UL 1973.
• Ukongeza, iinkqubo zebhetri ze-lead-asidi eziqinisekisiweyo kwaye zimakishwe ngokwe-UL 1778 akufuneki ukuba ziqinisekiswe ngokwe-UL 9540 xa zisetyenziswa njengonikezelo lwamandla okuxhasayo.

Ukuze kusonjululwe ingxaki yokunqongophala kwemigangatho yovavanyo yeebhetri ze-lead-acid kunye ne-nickel-cadmium kwi-UL 1973, iSihlomelo H (Vavanya iindlela ezizezinye kwi-valve-regulated okanye i-vent lead-acid okanye i-nickel-cadmium ibhetri) yongezwa ngokukodwa uhlelo lwesithathu lwe-UL 1973 olukhutshwe ngoFebruwari 2022.

Olu tshintsho lubonisa uphuhliso oluhle ukwenzela ukwahlula iimfuno zofakelo olukhuselekileyo lwe-UPS kunye ne-ESS.Umsebenzi ongaphezulu uquka ukuhlaziya iNqaku le-NEC ye-480 ukujongana neemfuno zofakelo olungcono lweetekhnoloji ngaphandle kwe-lead-acid kunye ne-nickel-cadmium.Ukongezelela, umgangatho we-NFPA 855 kufuneka uhlaziywe ngakumbi ukuze unike ukucaca ngakumbi kwimimiselo yokukhusela umlilo, ngokukodwa malunga nobuchwepheshe obuhlukeneyo obusetyenziswa kwizicelo ezimileyo, nokuba ziyi-UPS okanye i-ESS.

Umbhali uthemba ukuba utshintsho oluqhubekayo luya kuphucula ukhuseleko loshishino, kungakhathaliseki ukuba i-UPS yendabuko okanye i-ESS isetyenziswa.Njengoko sibona izisombululo zogcino lwamandla zisanda ngeendlela ezibalulekileyo nezikhawulezayo, ukujongana nokhuseleko lwangaphakathi lweemveliso kubalulekile ekuvuleni ubugcisa obutsha bokhuseleko kunye nokuhlangabezana neemfuno zoluntu.
