Nidaamka Kaydinta Tamarta Tamarta oo dhamaystiranBESS) waxay u baahan tahay fiiro gaar ah laba tilmaame oo waxqabad oo waaweyn: mid la xidhiidha awoodda kaydinta tamarta iyo ka faa'iidaysiga, ie, la xidhiidha awoodda; iyo tan kale ee la xidhiidha awoodda dib u buuxinta ama sii deynta tamarta, ie, la xidhiidha awoodda. Xidhiidhka ka dhexeeya labadan dhinac waxa inta badan loo isticmaalaa in lagu kala saaro in nidaamka kaydinta tamarta uu tamar ku jihaysan yahay iyo in kale{6}}
Awoodda nidaamka kaydinta tamarta batteriga
Halbeeggani waxa uu matalaa awoodda tamarta ugu badan ee aragtida ee nidaamka kaydinta uu hayn karo, sida caadiga ah lagu muujiyey kilowatt{0}}saacadaha (kWh) ama megawatt{1}}saacadaha (MWh). Tani waa mid ka mid ah halbeegyada ugu muhiimsan ee nidaamka kaydinta tamarta; si kastaba ha ahaatee, awooddeeda dhabta ah ee la isticmaali karo waxaa saameeya qoto dheeraanta batteriga (DOD) iyo hufnaanta nidaamka.
Awoodda BESS (Nidaamka Kaydinta Tamarta Tamarta) waxay xooga saaraysaa cadadka tamarta la soo saari karo ama laga faa'iidaysan karo, taas oo ka duwan qeexida awoodda batteriga. Awoodda baytarigu guud ahaan waxa ay tixraacaysaa awoodda batteriga ee xaaladaha qaarkood (heerka sii daynta, heerkulka, danab ka joojinta, iwm.), waxaana lagu cabbiraa ampere{2}}saacadaha (Ah), oo ka dhigan isku xidhka wakhtiga hadda socda.
Habka kaydinta tamarta baytari:Awoodda ugu badan ee nidaamka
Awoodda ugu badan ee nidaamku waxay ka tarjumaysaa awoodda ugu badan ee dallacaadda iyo bixinta awoodda nidaamka kaydinta tamarta, waxaana guud ahaan lagu muujiyaa kilowatts (kW) ama megawatts (MW). Tilmaamaha waxqabadka waxaa lagu go'aamiyaa naqshadeynta dhammaan wareegga muhiimka ah, oo ay ku jiraan batteriga, wareegga gudbinta DC, isku xirka PCS, iyo AC, iyo xitaa khasaaraha inta lagu jiro hawlgalka ee awoodda ugu badan (khasaarahan inta badan waxaa loo rogi doonaa kulayl), taas oo saameynaysa naqshadeynta nidaamka xakamaynta heerkulka iyo qalabka kale ee caawinta. Nidaamyada kaydinta tamarta ee leh awood isku mid ah waxay yeelan karaan hawlqabadyo kala duwan sababtoo ah kala duwanaanshaha awoodda ugu badan; xitaa nidaamka kaydinta tamarta isku mid ah ayaa la kulmi doona farqi labajibaaran oo hufnaan ah sababtoo ah heerarka kala duwan ee awoodda hawlgalka.
Marka cabbirka korontadu uu yara weyn yahay marka loo eego cabbirka awoodda, sida 1 MW/500 kWh, waxa loo yaqaannaa awoodda{2}}nooca nidaamka kaydinta tamarta; Taa beddelkeeda, haddii ay tahay 500 kW/1 MWh, waxa loo yaqaan tamarta -nooca nidaamka kaydinta tamarta. Sidaa darteed, fikradda waqtiga ayaa mararka qaarkood la soo bandhigaa, sida kii hore oo lagu calaamadiyay 1 MW/0.5 saac, kan dambena 500 kW/2 saac.
Habka kaydinta tamarta batteriga: Tamar lumin iyo waxtarka
Hufnaanta nidaamka kaydinta tamarta ayaa ka tarjumaysa luminta tamarta inta lagu jiro habka dallacaadda iyo bixinta. Waxaa loo fahmi karaa sida saamiga tamarta uu sii daayo nidaamka iyo tamarta lagu soo rogay, oo sidoo kale loo yaqaan waxtarka wareegga. Khasaaradani kuma xidhna oo kaliya nooca farsamada ee batteriga kaydinta tamarta balse waxa ay sidoo kale ku xidhan tahay qaybaha korantada sida habka beddelka tamarta (PCS). Dareen cidhiidhi ah, hufnaanta nidaamku waxay ugu horayn ka tarjumaysaa khasaaraha ka jira wareegga ugu muhiimsan inta lagu jiro dallacaadda iyo dallacaadda, laga bilaabo batteriga, baska DC, PCS, iyo ugu dambaynta beddelka (haddii uu jiro). Si kastaba ha noqotee, codsiyada injineernimada wax ku oolka ah, isticmaalka awoodda qalabka wax-qabadka sida nidaamka xakamaynta heerkulka ayaa inta badan lagu daraa wadarta khasaaraha, sidaas darteed saameynaya waxtarka guud.

Habka kaydinta tamarta batteriga: Tirada wareegyada
Tirada xajmigu - wareegyada sii daynta batteriga ayaa go'aamiya cimrigiisa. Nidaamka kaydinta tamarta, sababtoo ah qiimaha sare ee batteriga, cimrigiisu wuxuu sidoo kale go'aamiyaa cimriga nidaamka oo dhan. Hoos-u-dhac ku yimaadda nolosha meertadu waxay keenaysaa korodhka iska caabbinta gudaha, taas oo kordhinaysa khasaaraha iyo kulaylka, sii kordhinaysa habka hoos u dhaca. Intaa waxaa dheer, dallacaadda joogtada ah iyo in ka badan - shubiddu waxay sababtaa kala dirida soo noqnoqda iyo dhigista walxaha macdan ee elektrolytka, taas oo sidoo kale si weyn u saamaysa nolosha meertada batteriga iyo badbaadada.
Nooc gaar ah oo lithium ah - baytariyada ion, tirada wareegyada ka hooseeya 1C ku dallaca iyo 1C xaaladaha sii daynta waxay muujinaysaa kala duwanaansho mug leh oo qoto dheer oo dheecaan ah (DOD), sida ka muuqata shaxanka.
Qiimaha kaydinta tamarta batteriga
Qiimaha nidaamyada kaydinta tamarta ayaa si dhow ula xidhiidha awoodda nidaamka, awoodda, iyo jawiga hawlgalka. Guud ahaan, tamarta -nooca nidaamka kaydinta, qiimaha baytariyadu waxay ku xisaabtamayaan qayb aad u saraysa; Inta lagu jiro awoodda{2}}nooca nidaamka kaydinta, qiimaha baytariyadu waa ka hooseeyaan. Si kastaba ha ahaatee, si kastaba ha ahaatee, qiimaha baakidhku hadda wuxuu ka kooban yahay qaybta ugu muhiimsan ee kharashka guud ee BESS, iyo sidoo kale waxay noqon doontaa aagga aasaasiga ah ee dhimista kharashka mustaqbalka.
Cutubka qiimaha waxa loo sheegi karaa yuan/kWh ama yuan/kW, laakiin si buuxda oo sax ah uma matalo macnihiisa. Sidaa darteed, waa lama huraan in la caddeeyo awoodda iyo awoodda labadaba isku mar marka laga hadlayo mashaariicda gaarka ah.
Habka kaydinta tamarta batteriga: wakhtiga jawaabta
Loogu talagalay BESS (Nidaamka Kaydinta Tamarta Tamarta), labadaba beddelka awoodda iyo wakhtiga jawaabta waxay ku jiraan xadka millise-ilbiriqsi, taas oo ku filan codsiyada nidaamka tamarta. Halkani waa halka ay BESS kaga fiican tahay marka la barbar dhigo hababka kaydinta tamarta jirka ee kale sida kaydinta tamarta duuliyaha iyo bamgareynta{1}}kaydka tamarta. Si kastaba ha ahaatee, xaddidaadda korantada, hababka rakibidda, iyo awoodda unugyada batteriga awgeed, awoodda iyo awoodda hal unug BESS waa kuwo xaddidan. Sidaa darteed, baaxad weyn oo - dhirta tamarta kaydinta tamarta, sida mid ka kooban daraasiin ah kuwa hoose ee caadiga ah -hababka kaydinta tamarta 5MW/2h ee ku xidhan si barbar socda, cidhiidhiga wakhtiga jawaabta ugu horrayn waxaa xaddidi doona habka isgaarsiinta iyo habka jadwalka. Waxa kale oo saamayn doonta hawlaha ay ka midka yihiin isku-duwidda korantada iyo ku-wareejinta xakamaynta hadda ee aaladaha barbar socda. Waqtiga jawaabta heerka ugu dambeeya ee saldhiga{10} waxa laga yaabaa in uu ku jiro boqolaal ilbiriqsi ama xitaa ilbiriqsi Dabcan, hal unug 5MW/2h BESS waa uun tusaale mala awaal ah; Isku-xirnaanta xad-dhaafka ah ee isbarbardhigga baytariyada lafteeda ayaa keenaya khataro badan oo badbaado ah. Xallinta dhibaatadan waxay u baahan tahay isbeddelada hababka xakamaynta kooxda iyo horumarka iyo adeegsiga tignoolajiyada cusub ee kaydinta tamarta sida xidhiidhka tooska ah ee sare{15}.
