Yiya kumxholo 
Izityalo zaseMzantsi Afrika zihlala zinciphisa ukhetho kwiindawo ezimbalwa ezibekiweyo. KRL-B261L Ihleli kudidi lwe-125 kW / 189 A kunye namandla aqikelelwe kwi-261 kWh. Le KRL-B522L moves the plant to 250 kW / 375 A and 522 kWh. Once duty approaches 750 kW or 1 MW, the project has moved into KRL’s larger container route.
Amandla, umbane okhoyo kunye ne-enerji banokubangela ukuba ikhabhathi ingasebenzi ngexesha elithile. Imveliso eqhelekileyo isenokuhlala ingaphantsi komlinganiselo we-kW, ngelixa ukuqala okudibanayo kusityhalela umbane okhoyo ngaphaya kweklasi epapashiweyo. Ezinye iindawo zigcina umda owaneleyo we-kW kodwa zisasilela kwi-enerji ngexesha lokunqamka kombane olude okanye ngexesha lokusebenza ebusuku. KRL C&I iinkqubo zokugcina amandla Ziquka iindidi ezininzi zezixhobo; umthwalo olinganisiweyo ugqiba ukuba yeyiphi ekufanele ibe kuloo odolo.
| Imeko yendawo iya kuqinisekiswa | Indlela yemveliso ye-KRL | Zipapashe iireyithingi zokuqala ukuhlolwa. |
|---|---|---|
| Amandla e-AC akhuselweyo ahlala ngaphakathi kwe-125 kW, umbane weprojekthi uhlala ngaphakathi kwe-189 A, kwaye umthwalo wamandla asebenzisekayo ofunekayo unganeliswa kwi-261 kWh edwelisiweyo. | KRL-B261L | 125 kW / 261 kWh / 189 A |
| Ikhabhathi encinci inemiqobo ngamandla, umbane, irhafu yamandla, okanye imfuneko yokufaka i-PV engaphezulu kwesangano sayo se-120 kW. | KRL-B522L | 250 kW / 522 kWh / 375 A / 240 kW yokufakwa kwe-PV |
| Umthwalo weprojekthi sele ukwiklasi ye-750 kW okanye i-1 MW kwaye imfuno yamandla iphakathi kwe-1.5 MWh okanye i-2 MWh. | Iindlela zokwakha ezinkulu zeekhonteyina ze-KRL | 750 kW / 1.5 MWh okanye 1000 kW / 2 MWh |
Itheyibhile iluncedo kwiscreen sokuqala. Ulandelelwano lokuqalisa umatshini, ifactor yamandla, iwindow ye-SOC esetyenziswayo, iilahleko zoguqulo, izixhobo zokuncedisa, amandla agciniweyo, ubushushu bendawo kunye nojongano lwezombane oluvunyiweyo kusafuneka ziqwalaselwe.
I-B261L isebenza kuphela xa imida ye-125 kW ne-189 A isasebenza.
I-B261L ikhupha amandla e-AC angama-125 kW xa ikwi-grid nangaphandle kwayo, umsinga we-189 A, amandla aqikelelweyo angama-261 kWh kunye nengeno ye-PV eyi-120 kW. Ikhowudi yodweliso yeyi KRL-B261L-125H3S-120M1-HX1.
Ibhetri yi-LiFePO4 enama-832 V kunye ne-314 Ah. I-KRL ikwabonisa ukupholisa okungamanzi, isikhululo sedizili, ukutshintsha kungaphantsi kwe-10 ms, i-RS485 / WiFi, ukhuseleko lwebhetri lwe-IP65, ukusebenza kungaphantsi kwe-2000 m, ukusebenza ngokunxuseneyo kude kube yizixhobo ezili-10 kunye nobunzima bekhabhathi obumalunga ne-2600 kg.
Inombolo nganye ichaphazela inxalenye eyahlukileyo yofakelo. I-pair ye-125 kW / 189 A sisikrini sokuqala se-AC. Ingeniso ye-PV ye-120 kW ibalulekile xa ingeniso eliqhelekileyo yelanga iyinxalenye yoyilo. Ubunzima bekhabhathi buba yingxaki yokuhambisa nokwakha xa kucwangciswa ufikelelo, ipadi kunye nokuphakanyiswa.
I-261 kWh yahlulwe nge-125 kW inika malunga neeyure ezi-2.09 xa kubhalwe phantsi. Ixesha lokusebenza le-AC elihanjisiweyo lixhomekeke kwi-SOC window evunyelweneyo, iilahleko zoguqulo, izixhobo zokuncedisa, i-SOC yomgcini, ubushushu bokusebenza kunye nayo nayiphi na inkxaso-mthetho yomthamo weprojekthi.
I-avareji ye-kW isenokubonakala ikhululekile nasemva kokuba umda wangoku ugqithisiwe. Iimoto ezininzi ezisombululayo ngexesha elinye zingayisa isikhululo ngogonyamelo ngaphaya kwe-189 A. Iindawo ezinomthwalo omkhulu we-DOL, i-star-delta, i-soft-starter okanye i-VFD kufuneka zisebenzise i- Uphononongo lokuqalisa i-motor ye-PCS eyi-125 kW phambi kokuba kuvunywe ikhabhinethi encinci.
I-B261L ihlala isebenza xa umthwalo olinganisiweyo ungqinelana nekhasi yayo ye-AC kwaye i-window yamandla ahanjisiweyo isasebenza emva kwezibonelelo zeprojekthi.
I-B522L itshintsha ngaphezu kobungakanani bekhabhathi.
I-B522L ifaka isiza kudidi lwe-250 kW / 375 A kunye namandla aqikelelwe kwi-522 kWh. Ikhowudi yayo yodidi ebonisiweyo yi-KRL-B522L-250H3S-240M2-HX1.
| Ipharamitha | B522L | Yintoni etshintshayo kwinqanaba lesiza |
|---|---|---|
| Amandla alinganisiweyo | 522 kWh | Ibhulokhi yamandla enkulu; ixesha lokusebenza elihanjisiweyo lisaxhomekeke kwi-SOC yeprojekthi kunye neenqikelelo zelahleko. |
| Amandla ombane e-AC | 250 kW | Inyusa udidi lomthwalo wokusebenza olukhuselweyo ngaphezulu kwe-B261L |
| Okwangoku | 375 A | Inyusa udidi lwangoku ye-AC efumanekayo |
| Ibhetri | LiFePO4, 832 V, 628 Ah | Ucwangciso lwebhetri olupapashiweyo lwale modeli |
| Ingeniso ye-PV | 240 kW | Iphindaphinda kabini isilinganiso esidwelisiweyo sokufaka i-PV ngokuthe ngqo xa ithelekiswa ne-B261L. |
| Ukubandisa | Ukupholisa ibhetri ngokuwisa ulwelo | Ukupholisa ngamanzi kuhlala kufakwe ngaphakathi kwekhabhathi. |
| Ixhwayelo ledizili | Ewe | Igcina ukudityaniswa kwejeneretha kufumaneka |
| Ukutshintsha | Ngaphantsi kwe-10 ms | Inani lokutshintsha elipapashiweyo; ukuqhubeka kwesiza kusafuneka kuvavanywe. |
| Okunxuseneyo | Kude kube zii-yunithi ezi-6 | Inika indlela yokwandisa kamva |
| Isiseko | Malunga nee-4900 kg | Utshintsho kwizakhelo, ukufikelela, isiseko, kunye nocwangciso lwezokwakha |
I-B522L enye kunye neekhabhathi ezimbini ze-B261L zingafikelela kwi-250 kW zizonke xa kubhalwe phantsi. Indlela ezifakwa ngayo yahlukile. I-B522L ibeka umthwalo kwikhabhathi enye eyi-250 kW / 375 A. Iiyunithi ezimbini ze-B261L zenza ii-converters ezimbini kunye noqhagamshelwano lweekhabhathi oluphindaphindiweyo, kunye noyilo lomzimba olumodular ngakumbi. Ukhuseleko, iintambo, ulondolozo, indawo ekhoyo kunye nezicwangciso zokwandisa zenza isigqibo phakathi kwezi zicwangciso zimbini.
Ingeniso ye-PV inokuba yindawo ebeka umda phambi kokuba amandla ebhetri enze njalo. I-B261L idwelisa i-120 kW kwaye i-B522L idwelisa i-240 kW. Iindawo ezifuna udidi olukhulu lwengeniso ethe ngqo ye-PV zingasebenzisa i- 522 kWh / 250 kW yekhabhathi yelanga, yokugcina amandla kunye nedizili njengereferensi yokuvala.
I-B522L idweliswe ukuba isebenze ngokunxuseneyo ukuya kutsho kwizixhobo ezithandathu. Umthamo wetransefoma, umbane we-switchboard, ukhuseleko, iindlela zeekhebula kunye nendawo ekhoyo zinokunqanda ukwandiswa phambi kokuba kufikelelwe kuloo mda wezixhobo.
Xa ikhabhathi encinci sele ixinezelekile kumsebenzi we-AC okanye kwigalelo le-PV, thelekisa imfuno elinganisiweyo ne-B522L phambi kokuba wongeze enye ikhabhathi encinci ngokuzenzekelayo. I-KRL Power inokuphonononga umthwalo, umbane okhoyo, usukelo lwexesha lokusebenza kunye nemfuno ye-PV xa kuthelekiswa neeklasi ezimbini.
Utshintsho lwerhafu kumgangatho wezityalo luyitshintsha yonke ifakelo.
Kwi-750 kW okanye i-1 MW, le projekthi sele idlulile kuthelekiso olulula lobukhulu bekhabhathi. Ukuphindaphinda iiyunithi zangaphandle ezincinci kongeza iindawo zokuphakamisa, iindlela zeekhebula, iindawo zokukhusela kunye nendawo ethathwayo. Iinkqubo ezinkulu ezidweliswe apha zezi:
- 750 kW / 1.5 MWh: KRL-B1M5L-750H3S-720M6-HX1, 1130 A, 720 kW PV, malunga ne-15 t
- 1000 kW / 2 MWh: KRL-B2ML-1MH3S-960M8-HX1, 1500 A, 960 kW PV, malunga ne-19.5 t
- Isikhongozeli: 6058 × 2438 × 2896 mm
Amaxwebhu ezokuthengwa kufuneka asebenzise igama elichanekileyo lomxholo-odolo. Ilebhile yosapho olubanzi ayiyondimela yekhowudi yeodolo ethile ye-750 kW okanye ye-1000 kW.
I-current inyuka iye kwi-1130 A okanye kwi-1500 A, ngelixa i-PV input inyuka iye kwi-720 kW okanye kwi-960 kW. Kwinqanaba elingolo, umthamo we-transformer, ulwabiwo lwe-LV okanye lwe-MV, ukhuseleko, iindlela zeekhebula, umthwalo wesiseko, ufikelelo lwe-crane kunye nendawo yokudibanisa zonke zingena kwingxoxo yokukhetha.
Iindawo ezigxile ekunciphiseni ityala le-Eskom zingaqhubeka ne Inkqubo yokugcina amandla ye-C&I eyi-2 MWh. Izityalo esele zikudidi lomthwalo lwe-1 MW zingasebenzisa i Inkqubo yokugcina amandla yefektri eyi-1 MW / 2 MWh njengereferensi yokuvala isicelo.
Iinkqubo ezinkulu kulo mthombo zisabala ukupholisa okusebenzisa ulwelo, uqhagamshelo lwedizili, ukutshintsha kungaphantsi kwe-10 ms kunye ne-RS485 / WiFi. Utshintsho olubanzi lwenzeka kakhulu kumsebenzi wogunyaziweyo wogesi nowezakhiwo kulo mgangatho.

Nje ukuba udidi lwezixhobo lucacile, i Isikhokelo sokukhetha iinkqubo zokugcina amandla zorhwebo nezoshishino iquka iitsheki zoyilo ezilandelayo. Izikhululo ezinokusetyenziswa kakhulu kwidizili nazo zingasebenzisa Ugcino lwebhetri yezoshishino lokunciphisa iindleko zedizili xa ixesha lokusebenza kwejeneretha liyinxalenye yemeko yokusebenza.
I-KRL Power inokuthelekisa umthwalo okhuselweyo, umsinga olinganisiweyo, i-backup window, umthamo we-PV kunye nolungiselelo lwejenereyitha olukhoyo phambi kokuba imodeli izinziswe. Isiphumo kufuneka sibonise zombini indlela yezixhobo kunye nezinto zasendaweni ezisafuna isiqinisekiso sobunjineli.
