Inkqubo yokuGcina ibhetri, idla ngokwaziwa njenge-HSS, isebenzisa iibhanki zebhetri enokuphinda iphinde igcine umbane ogqithisileyo kwigridi okanye imithombo ehlaziyiweyo yokusetyenziswa kamva. Njengamandla ahlaziyiweyo kunye neengcali zegridi ye-GRID, iinkqubo ze-Bess zidlala indima ebalulekileyo yokuzinzisa amandla kwaye kwandise ixabiso lamandla aluhlaza. Ke le ndlela isebenza ngokuchanekileyo njani le nkqubo?
Inyathelo loku-1: Ibhanki yebhetri
Isiseko sayo nayiphi na i-Bess ziibhetri eziphakathi zokugcina - iibhetri. Iimodyuli ezininzi zebhetri okanye "iiseli" zitshixiwe ukuba zenze "ibhanki yebhetri" ebonelela ngomthamo wokugcina ofunekayo. Iiseli zihlala zisetyenziswa yi-lithium-i-ion-i-ion ngenxa yoxinzelelo lwamandla aphezulu, ixesha elide lokuphila kunye nokuqhekeza ngokukhawuleza. Abanye abachwebazi njengokukhokelela-i-acid kunye neebhetri zokuhamba zikwasetyenziswa kwezinye iinkqubo.
Inyathelo 2: Inkqubo yokuguqula kwamandla
Ibhanki yebhetri iqhagamshela kwigridi yombane ngenkqubo yokuguqula yamandla okanye i-PCS. Ii-PC ze-PCS inamacandelo e-elektroniki enamandla anjenge-inverter, i-backs, kunye neefiltha ezivumela amandla ukuba ahambe kuwo omabini umkhombandlela phakathi kwebhetri kunye negridi. I-inverter iguqula ikhonkco elikhoyo
Inyathelo 3: Inkqubo yoLawulo lwebhetri
Inkqubo yolawulo lwebhetri, okanye i-BMS, ibeka iliso kwaye ilawula iseli nganye yebhetri kwibhanki yebhetri. I-BMS ilungelelanisa iiseli, ilawula i-voltage kunye ne-protsed ngexesha lokuhlawula kwaye ikhusela, kwaye ikhusele umonakalo ovela kwi-overgeng, ukukhutshwa okunzulu okanye ukukhutshwa okunzulu. Ibeka i-vormeter efana nevoldage, iqondo elikhoyo kunye neqondo lokushisa ukwenza umsebenzi webhetri kunye ne-liespan.
Inyathelo 4: Inkqubo yokupholisa
Inkqubo yokupholisa isusa ubushushu obugqithisileyo kwiibhetri ngexesha lokusebenza. Oku kubalulekile ukugcina iiseli ngaphakathi kwenqanaba lokuxinana kobushushu kwaye kwandise ubomi bomjikelo. The most common types of cooling used are liquid cooling (by circulating coolant through plates in contact with the batteries) and air cooling (using fans to force air through battery enclosures).
Inyathelo lesi-5: Ukusebenza
Ngexesha lemfuno yombane ophantsi okanye ukuveliswa kwamandla ahlaziyekayo, i-Bess ifumana amandla agqithisileyo ngenkqubo yokuguqula yamandla kwaye igcina kwibhanki yebhetri. Xa imfuno iphezulu okanye ihlaziyiwe ayifumaneki, amandla agciniweyo akhutshiwe kwigridi nge-inverter. Oku kuvumela i-Bess 'kwixesha lokutshintsha kwexesha "
Inkqubo yolawulo lwebhetri ibeka iliso kwimeko yesisele ngasinye kwaye ilawula izinga lentlawulo kunye nokukhupha ukugqobhoza ngokugqithisileyo, ukugcwala ngokugqithileyo kunye nokuhambisa iibhetri. Kwaye inkqubo yokupholisa isebenza ukugcina iqondo lobushushu bebhetri ngaphakathi kuluhlu olukhuselekileyo lokusebenza.
Kwisishwankathelo, inkqubo yebhetri yebhetri ihlawule iibhetri, amacandelo e-elektroniki office, ulawulo lwe-Inflow kunye nolawulo lobushushu kunye nolawulo lwefashoni lokugcina umbane odibeneyo wokugcina imfuno. Oku kuvumela itekhnoloji ye-Bess ukwandisa ixabiso lemithombo yamandla ahlaziyiweyo, yenza i-gridis isebenza ngokufanelekileyo kwaye ihlale isebenza, kwaye ixhase utshintsho kwikamva lamandla e-carbon cart.
Ngokunyuka kwemithombo yamandla ahlaziyekayo efana ne-solar kunye namandla omoya, iinkqubo zokwenza izinto ezinkulu zebhetri zebhetri (i-Bess) zidlala indima ebalulekileyo ekuzinziseni iigridi. Inkqubo yokugcina itekisi isebenzisa iibhetri ezinokuphinda isebenze ukuze igcine umbane ogqithisileyo ukusuka kwigridi okanye ukusuka kwi-Revewid kwaye ihambise amandla xa kufuneka. Itekhnoloji ye-Bess inceda ukwandisa ukusetyenziswa kwezinto ezihlaziyiweyo zethutyana kwaye kuphuculwe ukuthembeka kwegridi, ukusebenza kakuhle kunye nokuzinza.
I-Bess iqhele iqulethe izinto ezininzi:
1) Iibhanki zebhetri ezenziwe ngeemodyuli ezininzi zebhetri okanye iiseli zokubonelela ngomthamo ofunekayo wokugcina amandla. Ibhetri ye-lithium-ion isetyenziswa ngokuxhaphakileyo ngenxa yobunzima babo obuphezulu, ixesha elide lokuphila kunye nokukhawulezisa ukutshabalalisa amandla. Abanye abangamachiza njengokukhokelela-i-acid kunye neebhetri zokuhamba ziyasetyenziswa.
2) Inkqubo yokuguqula amandla (i-PC) edibanisa ibhanki yebhetri kwigridi yombane. I-PCS ine-inverter, iguquguquko kunye nezinye izixhobo zolawulo ezivumela amandla ukuba ahambe kuwo omabini umkhombandlela phakathi kwebhetri kunye negridi.
3) Inkqubo yoLawulo lwebhetri (i-BMS) ebeka iliso kwaye ilawula imeko yendlela yebhetri. I-BMS ilungelelanisa iiseli, ukukhusela ukujongana nomonakalo wokungaphezulu okanye ukuhambisa amanzi, kunye nokubeka i-parameters parameter njenge-voltage, iqondo lokushisa ngoku.
I-4) Inkqubo yokupholisa esusa ubushushu obugqithisileyo kwiibhetri. Ulwelo okanye ukupholisa okusekwe kumoya kusetyenziselwa ukugcina ibhetri ngaphakathi kuluhlu lwamaqondo obushushu afanelekileyo kwaye kwandise ubomi bexesha.
5) Izindlu okanye isikhongozeli esikhusela kwaye siyikhusela yonke inkqubo yebhetri. Iindawo ezivaliweyo zebhetri zangaphandle kufuneka zibe zemozulu yemozulu kwaye zikwazi ukumelana nobushushu obukhulu.
Imisebenzi ephambili ye-Bess yile:
• efumana amandla agqithisileyo kwigridi ngexesha lebango eliphantsi kwaye akhulule xa imfuno iphezulu. Oku kunceda ukuzinzisa i-voltage kunye nokuguquguquka rhoqo.
• Gcina amandla ahlaziyekayo kwimithombo yolwazi njengezilwanyana zelanga kunye nemveliso yomoya enobume kwaye ungenise amandla agciniweyo xa ilanga lingakhanyisi okanye umoya awukhangeli. Ngeli xesha-tshintsha amandla ahlaziyekayo xa kufuneka uninzi.
Ukubonelela ngamandla okugcina ngasemva ngexesha le-grid okanye ukuphuma kokugcina izibonelelo ezinobuchule ezisebenzayo, nokuba seziqithini okanye kwi-grid-tid ye-grid.
• Thatha inxaxheba kwiimpendulo zengxowa kunye neenkqubo zenkonzo ye-anisellary ngokudibanisa amandla empahleni okanye ezantsi kwimfuno, ukubonelela ngokumiselwa rhoqo kunye nezinye iinkonzo zegridi.
Ukuqukumbela, njengoko amandla ahlaziyekayo ayaqhubeka nokukhula njengepesenti yeegridi zamandla emhlabeni wonke, iinkqubo ezinkulu zokugcina i-Bhende ziya kudlala indima ebonakalayo ekwenzeni ukuba loo mandla acocekileyo afumaneke kwiwotshi. Itekhnoloji ye-Bess iya kunceda ukwandisa ixabiso lokuphinda libe nokuhlaziywa, ukuzinzisa amandla e-Grids kwaye ixhase utshintsho kwixesha elizayo, eliphantsi le-carbon.
