I-PCS ehlanganisiwe nesinyathelo-I-Transformer Ephezulu ye-BESS
I-PCS Edidiyelwe kanye Nesinyathelo-I-Up Transformer ye-BESS yakhelwe izitshalo zokugcina amandla ezidinga ukuguqulwa okuhlangene, okumaphakathi kanye nesixazululo{1}}sokukhuphuka.
Ngokuhlanganisa ukuguqulwa kwe-PCS, ukukhuphula{{0}uxhumo lwe-transformer, ukulawulwa kweqembu lebhethri, kanye nedizayini yokuvikela, kusiza ukunciphisa ukufaniswa kwemishini, izintambo zenkundla, umsebenzi wokuphakamisa, nobunkimbinkimbi bokufaka. Ngokuphathwa kweqembu elizimele lebhethri kanye negridi{2}}izindlela zokusebenza eziguquguqukayo, isekela ukusebenza okuthembekile kwendawo eyodwa ye-BESS kuyilapho igcina isakhiwo sesayithi kulula ukusisebenzisa nokunakekela.
Kungani lesi siteshi esihlanganisiwe se-PCS transformer
Imikhiqizo yethu Yesitsha Sokugcina Ibhethri inikeza uhla lwezinzuzo.
Ukuguqulwa kwe-PCS kanye Nesinyathelo-Phezulu Ngeyunithi Eyodwa
Ngokungafani ne-PCS evamile ephatha ngokuyinhloko ukuguqulwa kwe-DC/AC, lesi sixazululo esihlanganisiwe sihlanganisa ukuguqulwa kwe-PCS okumaphakathi nendawo{0}}yokuxhuma kwe-transformer phezulu kuyunithi eyodwa. Isiza ukuguqula amandla ebhethri e-DC abe yi-AC okukhiphayo futhi kukhuphule i-voltage ukuze kuxhumeke i-medium-voltage BESS.
Igridi{{0}Izindlela Zokusebenza Eziguqukayo
Nge-PQ, VF, SVG, VSG, high/low voltage ride-ngokusebenzisa, off-ukusebenza kwegridi, nemisebenzi yokuqalisa emnyama, isistimu ingasekela izimfuneko zokusebenza ezihlukene kugridi{2}}eceleni nasekusebenziseni{3}}izinhlelo zokusebenza zesikali sokulondoloza amandla.
-Ukusebenza Kahle Kwesithathu-I-Topology Yezinga
Yakhelwe-nge-topology yamazinga amathathu, isistimu isekela ukuguqulwa kwamandla okusebenzayo nokusebenza kahle kwesistimu okufika kokungu-98%. Lokhu kusiza ukuthuthukisa ukusebenza kokudluliswa kwamandla kumasistimu okugcina amandla ebhethri amaphakathi.
-Izinga Lokuvikelwa Kogesi Okuningi
Idizayini ehlanganisiwe ihlanganisa ukuvikela kukagesi kanye nesofthiwe-imisebenzi yokuphepha kwezingxenyekazi zekhompuyutha ukusekela ukusebenza okuphephile kumaphrojekthi{1}amandla aphezulu e-BESS. Lokhu kusiza ukuthuthukisa ukuthembeka kwesistimu lapho ukuguqulwa kwamandla, ukukhuphuka kwe-voltage-, kanye nokuxhumeka kwegridi kusebenza ndawonye.

I-System Architecture
Njengesistimu yokuguqula amandla emaphakathi (PCS) ehlanganiswe-ne-transformer ekhuphukayo, lesi skid se-BESS PCS sakha isixhumanisi sikagesi phakathi-kwebhethri ye-voltage DC ibhasi kanye-negridi ye-voltage emaphakathi. Akubandakanyi amabhethri ngokwawo; yamukela i-1000–1500 V DC kusuka kokubili noma kwezineizitsha zokugcina amandla ebhethri, iyiguqulela ku-AC, bese inyusa amandla kagesi ifike kuphrojekthi-elungiselelwe u-10–35 kV ukuze kuxhunywe igridi.
Yini engaphakathi esiteshini esididiyelwe
Isigaba se-PCS esimaphakathi
I-PCS emaphakathi iguqula amandla ebhethri e-DC abe yi-AC futhi, ngokuhlehla, ilawula iphrofayili yokushajwa yeqembu ngalinye lebhethri. Ukuphathwa kweqembu lebhethri elizimele kuvumela amaqembu amabili noma amane ukuthi asetshenziswe futhi avikelwe ngokuhlukana ngaphakathi kwebhulokhi yamandla efanayo.
Khuphuka{{0}isigaba se-transformer
Isinyathelo-i-transformer ekhuphukayo ye-BESS inyusa i-voltage AC ephansi{{1}yezinga eliphezulu{2}}elimaphakathi{2}}lokuxhuma kwegridi. Kokubili ama-transformer-omile kanye namafutha{5}}acwilisiwe ayatholakala ukuze isiteshi sikwazi ukuhambisana nezindawo zomlilo-ukuphepha, isimo sezulu, kanye nezimfuneko zokusetshenziswa.
Isilawuli sesiteshi nokuxhumana

I-PCS ehlanganisiwe kanye{0}}ne-transformer ekhuphukayo ye-BESS - FAQ
Umbuzo: Ingabe lo mkhiqizo uyibhethri?
IMP: Cha. I-PCS ephakathi nendawo futhi{1}}inyusa i-transformer station. Iguqula futhi inyuse amandla phakathi kwebhasi le-DC yebhethri kanye-negridi ye-voltage emaphakathi, kodwa amabhethri ahlinzekwa ngokuhlukene njengeziqukathi zokugcina amandla ebhethri.
Q: Yini efakwe esiteshini esididiyelwe?
A: I-PCS emaphakathi,-i-transformer enyukayo-uhlobo olulomile-noma uwoyela-ocwilisiwe), isilawuli sesiteshi nokuxhumana, namandla asizayo nokuphathwa kwe-thermal, ene-MV switchgear/RMU elungiselelwe iphrojekthi ngayinye. Izintambo ze-DC, izintambo ze-MV, nesisekelo kuvame ukunikezwa yi-EPC.
Q: Ingakwazi ukuxhuma ku-33 kV noma ku-35 kV?
A: Yebo. Okukhiphayo kwe-MV kucushwe kugesi wegridi eyodwa phakathi kwebanga lika-10–35 kV, okuhlanganisa no-33 kV no-35 kV, ngokusekelwe ekucushweni kwesiguquli sephrojekthi.
Q: Aphathwa kanjani amaqembu amabhethri amabili noma amane?
IMP: Isiteshi sihlinzeka ngokulawula okuzimele nokushajwa kweqembu ngalinye lebhethri, ngakho amaqembu amabili noma amane angasebenza futhi avikelwe ngokuhlukene ngaphakathi kwebhulokhi yamandla engu-6.9 MVA efanayo.
Q: Ingabe ukusebenza kahle kwe-PCS okungu-98% noma ukusebenza kahle kohlelo?
A: Uhlu lwama-98% lusebenza kahle kakhulu lwesistimu. Iphoyinti eliqondile lokulinganisa nesimo somthwalo siqinisekiswa kudatha yephrojekthi.
Q: Ingabe iyawusekela umsebenzi wokwakha igridi-?
A: Yebo. Eceleni kwegridi-ngokulandela ulawulo lwe-PQ, isiteshi sisekela ukusebenza kwe-VSG (igridi-ukwakheka), i-HVRT/LVRT ukugibela-udlule, uvale-ukulawula kwegridi ye-VF, kanye nokuqalisa okumnyama, kuncike kukhodi yegridi yasendaweni.
Q: Yiluphi ulwazi oludingekayo ukuze uthole ikhotheshini?
A: Amandla adingekayo (MW/MVA), ibhethri le-DC voltage range, inombolo yamaqembu ebhethri, i-voltage yegridi nefrikhwensi, izwe, noma iyiphi igridi-imfuneko yokwakheka, okuthandwayo kwe-transformer, izinga lokushisa le-ambient, ukuphakama, kanye nedethi yokulethwa okuqondiwe.
