Isistimu Yesitoreji Samandla Ebhethri vs i-UPS: Iyiphi Elingana Iphrojekthi?

Impendulo eqondile: Khetha i-UPS uma imfuneko eyinhloko iqhubekayo, amandla anesimo sokulayisha okuzwela ukuphazamiseka. Khetha isistimu yokugcina amandla ebhethri uma iphrojekthi idinga ukushintshwa kwamandla, isilawuli sesidingo esiphezulu, ukuhlanganisa okuvuselelekayo noma ukwenza isipele sesikhathi eside esiklanywe ngokukhethekile. I-BESS ingasekela imithwalo ebucayi, kodwa akufanele ithathwe njenge-UPS ngaphandle kokudluliselwa okuqinisekisiwe, ukusebenza kwe-island kanye nekhwalithi yamandla.

Amasistimu womabili angase aqukathe amabhethri namandla kagesi, kodwa athengelwa izinjongo zokulawula ezihlukene. I-UPS ivamise ukuhlolwa ngokuqhubeka komthwalo, ikhwalithi yokuphumayo, ukuziphatha okuchichimayo, ukuhlelwa kokudlula kanye nokuzimela. I-BESS ehlanganiswe negridi ngokuvamile ihlolwa ngamandla, amandla asebenzisekayo, umjikelezo wemisebenzi, isu lokuthunyelwa kwempahla, indawo yokuxhuma, izinhlelo zokuphepha kanye nezinsizakalo zezomnotho okufanele izenze.

Abathengi ababuyekeza i-Dingsheng's uhla lokugcina amandla ezentengiselwano nezimboni kufanele iqale ngomthwalo kanye nenhloso yokusebenza. Umbuzo awukona ukuthi yibuphi ubuchwepheshe obuzwakala buthuthuke kakhulu. Umbuzo uwukuthi yini okufanele ihlale inamandla, ukuthi uhlelo kufanele luphendule ngokushesha kangakanani, isikhathi esingakanani, nokuthi yini okufanele yenziwe uhlelo phakathi nokusebenza kwegridi evamile.

Uyini Umehluko Oyinhloko Phakathi kwe-BESS ne-UPS?

Umsebenzi oyinhloko we-UPS ukuqinisekisa ukuqhubeka komthombo wamandla we-AC futhi, kuye nge-topology, ukugcina okukhiphayo ngaphakathi kwezici zekhwalithi zamandla ezicacisiwe. I-IEC 62040-3 ikhuluma ngezidingo zokusebenza nezivivinyo zezinhlelo eziphelele ze-UPS. Ngakho-ke isinqumo se-UPS siqala ngokubekezelela umthwalo obalulekile wokuphazamiseka nokuphazamiseka.

Isistimu yokugcina amandla ebhethri iyimpahla yamandla ehlanganiswe negridi. Ingashaja futhi ikhiphe ngokuya ngesu lokuphatha amandla. Izinhloso zephrojekthi ezijwayelekile zifaka ukushefa okuphezulu, ukuguquguquka kwesikhathi sokusetshenziswa, ukusetshenziswa kwe-photovoltaic, impendulo yokufuna, ukusekelwa kwamandla kanye nekhophi yekhophi yemithwalo ekhethiwe lapho i-architecture isekela khona.

Ukugqagqana kudala ukudideka. I-UPS yesimanje kwesinye isikhathi ingabamba iqhaza ekuthuthukiseni amandla, futhi i-BESS kwesinye isikhathi inganikeza amandla ayisipele. Asikho isitatimende esifakazela ukuthi umkhiqizo owodwa ungangena esikhundleni somunye kuphrojekthi ethile. Umthengi kufanele aqhathanise i-topology yesistimu nokusebenza okuhloliwe ngokumelene nemfuneko yomthwalo.

Uzwela Kangakanani Umthwalo Ekuphazamiseni?

Faka ohlwini imithwalo ngokomphumela, hhayi ngama-kilowatts kuphela. Amaseva, izilawuli zezinqubo, amasistimu okuphepha, okokusebenza kwezokwelapha noma kwaselabhorethri kanye nezishintshayo ezizwelayo zingasabela ekuphazamisekeni okufushane kakhulu noma ukuphazamiseka kukagesi. Amaphampu, okokusebenza kwe-HVAC, isiqandisi kanye nemithwalo evamile yokukhiqiza ingase ikubekezelele ukudluliswa isikhathi eside kodwa kudinga amandla engeziwe.

Kuwo wonke amaqembu okulayisha, bhala isikhathi sokuphazamiseka esivumelekile, imikhawulo kagesi kanye nemvamisa, ukuzwela kokuqala kwamanje, okuvumelanayo, isici samandla, ukuqala kabusha ukuziphatha kanye nokuzimela okudingekayo. Uhlelo lube seluklanywa eduze kwamabhasi anemithwalo ebucayi esikhundleni sesicelo esingachazwanga “sokwenza isipele ifektri.”

Iphutha lokucaciswa eliphindelelayo lisho ukuthi ukwenza isipele kufanele kungabi nazihibe ngaphandle kokuchaza umkhawulo wokudlulisa olinganisekayo noma okokusebenza okufanele kudlule. Umphakeli akakwazi ukuqinisekisa ukuqhubeka kusichasiso. Imfuneko idinga inani lesikhathi, iphrofayela yomthwalo kanye nokuhlolwa kokwamukela.

Kunini lapho i-UPS iyisinqumo esifanele?

I-UPS ivamise ukuba umzila onamandla lapho umthwalo ozwela ukuphazamiseka udinga amandla e-AC anesimo kanye nesakhiwo esicacisiwe sokuqhubeka. Umthengi kufanele aqhathanise ama-topology aku-inthanethi, asebenzisanayo noma amanye afanele ngokucaciswa kwephrojekthi, kanye nokudlula okumile, ukudlula ukunakekela, ukuphindaphinda, ukuzimela kwebhethri nokuziphatha kokuhlanza amaphutha.

Isikhathi sokusebenza se-UPS ngokuvamile siklanyelwe ukuvala ukucisha okufushane, ukusekela ukuvala shaqa okuhlelekile noma ukumboza isikhawu ngaphambi kokuthi kuqale ijeneretha. Izintambo zebhethri ezinwetshiwe zingandisa isikhathi sokusebenza, kodwa ukuzimela okude kushintsha indawo, ukupholisa, ukugcinwa nokugcinwa kwebhethri esikhundleni sezomnotho. Kungase kungasebenzi usayizi we-UPS wamahora omthwalo obanzi wesikhungo lapho iqembu elincane kuphela elidinga amandla angaphazamiseki.

Khetha umngcele we-UPS ngokucophelela. Uma izilawuli ezibalulekile zinamandla e-UPS kodwa amaswishi enethiwekhi yazo, ukupholisa, ama-actuator noma izisiza ezikhuphuka nomfula zingenawo, inqubo isengase yehluleke. Imephu yokuncika komthwalo iwusizo kakhulu kunohlu lwamagama emishini.

Kunini I-BESS Iyindlela Efaneleka Kakhudlwana?

I-BESS iba ngofaneleka kakhulu lapho iphrojekthi kufanele ihambise amandla phakathi nesikhathi, yehlise inani eliphakeme lokufunwa, imunce isizukulwane esivuselelekayo noma isekele umthwalo omkhulu isikhathi esinqunyiwe. Isilinganiso samandla sinquma ukuthi ungakanani umthwalo onganikezwa ngesikhathi esisodwa; amandla asebenzisekayo kanye nemikhawulo yokusebenza inquma ukuthi isevisi ingaqhubeka isikhathi esingakanani.

UDingsheng ubala i I-BESS-PLUS 500GP uhlelo lokugcina amandla ngaphakathi kwephothifoliyo yayo yokugcina amandla. Ikhathalogi ikhomba imodeli yomndeni ye-E-MATE 500GP nedatha yemojula yebhethri, kodwa abathengi kufanele bacele umngcele wesistimu onikeziwe ophelele: amandla asebenzisekayo, amandla okushaja/akhipha, i-PCS, i-EMS, ukuvikela, ukupholisa, ububanzi bokuphepha emlilweni, indawo evalekile, i-transformer noma i-switchgear interfaces, ukuxhumana kanye nokusebenza.

I-BESS esekela ukwenza isipele idinga okungaphezu komthamo webhethri. Idizayini kufanele isungule ireferensi kagesi ezinzile kanye nemvamisa lapho kudingeka, ihlukanise isiqhingi esihlosiwe kugridi, ivikele inethiwekhi esesiqhingini, ilawule ukulayishwa kwayo futhi iqondise ukubuyiselwa. Uma leyo misebenzi ingekho noma ingaphandle kobubanzi, i-BESS ingase ime ngesikhathi sokucisha kwegridi nakuba amandla agciniwe etholakala.

Ingabe I-BESS Ingangena Esikhundleni Se-UPS Yemithwalo Ebucayi?

I-BESS ingamiselela eminye imisebenzi ye-UPS kuphela lapho ukwakheka kwayo nokusebenza okuhloliwe kuhlangabezana nemfuneko yomthwalo obalulekile. Umthengi kufanele aqinisekise ukutholwa nokuziphatha kokudlulisa, imodi yokusebenza ye-inverter, ukwenza igridi noma elinye ikhono lokumisa lapho kudingeka khona, ikhwalithi yokuphumayo, impendulo yokulayisha ngokweqile, ukulandelana kokuqalisa okumnyama, indlela yokudlula kanye nokutholwa ngemva kokubuya kwegridi.

Ngemithwalo engakwazi ukwamukela ukuziphatha kokudlulisa kwe-BESS, idizayini eyingxube ingase ifaneleke kakhulu. I-UPS yasendaweni ingavikela izilawuli nezinto zikagesi ngoshintsho, kuyilapho i-BESS inikezela ngamandla esikhathi eside ebhasini elibanzi lomthwalo obalulekile. Lezi zinhlelo ezimbili zibe sezixazulula izingxenye ezihlukene zenkinga yokuqhubeka.

Ungacabangi ukuthi isimangalo se-millisecond esithathwe engxenyeni eyodwa sifakazela ukusebenza kwesistimu ekupheleni ukuya ekupheleni. Amadivayisi okuzivikela, amaswishi okudlulisa, ukulawula okunengqondo, amandla e-transformer kanye nokuqaliswa kokulayisha konke kuthinta lokho okokusebenza okuhlangabezana nakho ngempela.

Iluphi Uhlelo Olungcono Olusekela Izinjongo Zezindleko Zezindleko?

I-UPS evamile ivamise ukuthethelelwa ngokugwenywa kwesikhathi sokuphumula kanye nokuvikelwa kwekhwalithi yamandla. I-BESS ingase futhi idale inani ngesikhathi sokusebenza okuvamile ngokushefa okuphezulu, ukushintsha intela, ukuthwebula i-photovoltaic noma ezinye izinsizakalo zegridi ezivunyelwe yimakethe kanye nesivumelwano sokuxhumanisa.

Ukuqhathanisa komnotho kufanele kufanekisele umsebenzi wokuthumela, hhayi ukufakwa kwe-kWh kuphela. Okugciniwe okugcinelwe ukwenza ikhophi yasenqolobaneni akukwazi ukusetshenziselwa kanyekanye ukwenza i-arbitrage. Ukuhamba ngebhayisikili njalo kungathinta ukucekelwa phansi nezimo zewaranti. Ukonga okufunwayo kuncike ewindini lokulinganisa lentengo kanye nekhono lokubikezela noma ukulawula ukuphakama kwesayithi.

Isihloko esikhona simayelana kungani izingcaphuno zokugcina amandla zihluka ku-kWh efanayo ichaza ukuthi kungani i-PCS, i-EMS, ukupholisa, ukuphepha kanye nemingcele yokuthumela ishintsha izindleko. Isinqumo se-BESS-versus-UPS kufanele senziwe ngaphambi kokuba amakhotheshini aqhathaniswe, ngoba lezi zindlela ezimbili zingase zixazulule izinkinga ezihlukene.

Imiphi Imingcele Yokuphepha Nokuthobela Ehlukile?
