Yiya kumxholo 
Amaziko aseMzantsi Afrika anqabileyo ukuba afikelele kwesi sigqibo ngokuthelekisa umthamo weekhabhathi zodwa. Iseti yokondla imisela umda wamandla; i-window yokusebenza imisela imfuno yamandla. Ukugqwethana kwemoto, i-PV input kunye neseti yedizili esele ikhona zinokuphinda ziyitshintshe le ngqesho. Amandla e-KRL Ibeka ezo misebenzi kuloo ntlangano yezinto ezipholisa ngamanzi zangaphandle, ngoko ke umbuzo obalulekileyo ngulo, yeyiphi ikhabhathi esayilingana nentsimbi njengoko isebenza namhlanje.
| Imeko yesityalo | Imveliso ye-KRL | Iireyithingi ezibalulekileyo kuqala |
|---|---|---|
| Umthwalo osayinweyo malunga ne-80-120 kW kunye ne-189 A usemile. | B261L | 125 kW / 261 kWh / 189 A |
| Ukugqwethana kwemini kungene malunga ne-140-220 kW. | B522L | 250 kW / 522 kWh / 375 A |
| Umthwalo osayinweyo yi-400 kW nangaphezulu, okanye amandla afunekayo sele eyi-1.5-2 MWh. | Usapho lwe-B2M6L | 750 / 1000 kW kunye ne-1.5 / 2 MWh |
Itheyibhile isisiseko nje. Izityalo zinokuhlala zingaphantsi kwe-125 kW ixesha elininzi losuku zize zikwazi ukukhula ngaphezu kwe-B261L xa iimoto ezininzi zikufuphi. Enye indawo isenokuba nomda ophezulu wamanje okhululekileyo kodwa idinge amandla agciniweyo amaninzi ebusuku.
I-B261L ilingana neholweni encinci yomsebenzi de umondli athi ngenye indlela.
Ukunqunyulwa kombane kunokwenzeka emva kwemini, kodwa ikhabhathi isafuneka ithwale uluhlu lokwenene olutyikityiweyo: ulawulo lwenkqubo, izibane kunye neemoto ezivunyelwe ukuba zisebenze ngaxeshanye.
Iholo enye isenokudla amandla angangaphantse abe yi-80-120 kW. Ukuqalisa kuhlala kulawulwa kwaye i-189 A isanele kwindlela engenayo. Loo nto lulolona luhlu lwesiqhelo lwe- KRL-B261L 125 kW / 261 kWh, imodeli KRL-B261L-125H3S-120M1-HX1.
Amanani ayo apapashiweyo ngama-125 kW amandla e-AC xa ikwi-grid nangaphandle kwayo, i-189 A umsinga, i-261 kWh yamandla aqikelelweyo kunye ne-120 kW yokufakwa kwe-PV. Ibhetri yi-LiFePO4 ekwi-832 V ne-314 Ah. I-KRL ikwaludwelisa ukupholisa okukwi-liquid, isibuko sedizili, ukutshintsha okungaphantsi kwe-10 ms, i-RS485 / WiFi, ukhuseleko lwebhetri lwe-IP65, ukuphakama okungaphantsi kwe-2000 m kunye nokusebenza ngokunxuseneyo kweeyunithi ezifika kwezili-10. Ubunzima bekhabhathi malunga ne-2600 kg.
Inani lamandla kulula ukulifunda gwenxa. Kwi-125 kW, i-261 kWh ngokwamaphepha ilingana neeyure ezimbini. Umthwalo osayinweyo we-80 kW uhlala ixesha elide. Ukusebenza ngamandla apheleleyo ubusuku bonke obuneeyure ezisibhozo akungeni kuloo klasi yamandla.
Umbane unokuba ngumda onzima kuqala. Iziomisi ezimbini ezisebenza ngaxeshanye zinokutyhala isiza ngaphaya kwe-189 A, nokuba umthwalo wazo oqhelekileyo wokusebenza ubonakala ungasindi. Ngelo xesha, ikhabhathi encinci ayonelanga kumsebenzi wokondla umbane, hayi kuba inqongophele ngamandla.
Ukupholisa okukwi-liquid kunye ne-diesel port zilungile kuba sele ziyinxalenye yecaciso lekhabhathi. Izityalo ezinejenereyitha eyadini azidingi usapho lwemveliso olwahlukileyo ukuze nje kugcinwe loo ndawo yokudibanisa ikhona.
I-B522L iyenza ingqiqo xa ikhabhathi ye-125 kW iqala ukuxinana.
Imigca yezokvelisa yesibini, ukupholisa okongeziweyo okanye indawo yokutshaja inokunyusa ukusebenza ngaphezulu kwesigaba sasemva emini ukuya kwi-140-220 kW. Ingxaki ayiseyonto yotheoriya xa umthwalo sele usoloko usondela kumda we-125 kW.
I- KRL-B522L 250 kW / 522 kWh Isusa isiza kwi-converter enye eyi-250 kW kunye nekhilasi yomsinga eyi-375 A. Imodeli ye-odolo yi-KRL-B522L-250H3S-240M2-HX1.
| Ipharamitha | B522L |
|---|---|
| Amandla alinganisiweyo | 522 kWh |
| Amandla ombane e-AC | 250 kW |
| Okwangoku | 375 A |
| Ibhetri | LiFePO4, 832 V, 628 Ah |
| Ingeniso ye-PV | 240 kW |
| Ukubandisa | Ukupholisa ibhetri ngokuwisa ulwelo |
| Ixhwayelo ledizili | Ewe |
| Ukutshintsha | Ngaphantsi kwe-10 ms |
| Okunxuseneyo | 6 |
| Isiseko | Malunga nee-4900 kg |
Iikhabhathi ezimbini ze-B261L zinokubonelela nangee-converter ezimbini ze-125 kW, kodwa isiphumo asikokufakwa okufanayo. I-B522L ibeka umthwalo we-250 kW kwi-converter enye, kwindlela enye ye-375 A nakwikhabhathi enye enobunzima obumalunga ne-4.9 t.
Uphahla lunokutyhala iprojekthi kwicala elinye. I-B261L ikhupha i-120 kW yamandla elanga (PV); i-B522L ikhupha i-240 kW. Iindawo ezifuna amandla elanga amakhulu zingasebenzisa i- 522 kWh / 250 kW yekhabhathi yelanga, yokugcina amandla kunye nedizili njengolungiselelo olufanelekileyo.
I-KRL idwelisa ukusebenza ngokunxuseneyo kweeyunithi ze-B522L ezifikelela kwezintandathu. Oku kunika isikhululo indawo yokongeza enye ibhloko ye-250 kW kamva, ngaphandle kokwenza ngathi ukwandiswa kwixesha elizayo kufuneka kufakwe ukususela kusuku lokuqala.
Imithwalo yomlinganiselo wezityalo ifuna isixhobo esahlukileyo.
Iindawo esele zixhobe nge-400 kW nangaphezulu, okanye ezifuna i-1.5-2 MWh ngexesha lokusebenza, azisajongene nengxaki efanayo yofakelo. Iikhabhathi ezininzi ezincinci zithetha iilifti ezininzi, iindlela ezininzi zeekhebula kunye neendawo ezininzi zokudibanisa eziphindaphindiweyo kwiyadi.
Indlela enkulu ye-KRL yi KRL-B2M6L Usapho:
- 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
Ezo nani zitshintsha umsebenzi we-system yokugcina. Indlela yangoku inyuka iye kwi-1130 A okanye i-1500 A. Ingeniso ye-PV inyuka iye kwi-720 kW okanye i-960 kW. Isixhobo ngokwaso siba yinto yomatshini enobunzima obumalunga ne-15 t okanye i-19.5 t kwibhokisi ye-20-ft.
Iiwebhusayithi eziphonononga ukugcinwa ikakhulu malunga nokuncitshiswa kwetyala le-Eskom zingaqhubeka nge Inkqubo yokugcina amandla ye-C&I eyi-2 MWh. Iifektri ezisele zifikelele kudidi lwe-1 MW zingasebenzisa i Inkqubo yokugcina amandla yefektri eyi-1 MW / 2 MWh njengereferensi yokuvala.
Ukupholisa ngamanzi, uqhagamshelwano lwedizili, utshintsho olungaphantsi kwe-10 ms kunye ne-RS485 / WiFi zihlala ziyinxalenye yosapho olunye. Eyona nto itshintshayo kakhulu bubungakanani bomsebenzi wombane nowokwakha ojikeleze iyunithi.
Faka isizathu sokukhetha imodeli kwi-odolo.
Imida yokuthenga kulula ukuyikhusela xa imodeli ekhethiweyo inokubotshelelwa kwisithintelo sesiza esinye okanye ezibini endaweni yokuthanda okungaqondakaliyo komthamo ongaphezulu.
| Ubungqina besiza | Indlela yemveliso | Thenga itsheki |
|---|---|---|
| Umthwalo osayiniweyo we-80-120 kW, ukugqithisana kwemoto kuhlala kungaphantsi kwe-189 A, umthwalo wamandla uhlala umfutshane. | B261L | 125 kW / 261 kWh / 189 A |
| Ukugqwethana kwe-140-220 kW, i-189 A ayisabambi, okanye uphahla lufuna isibuko se-PV esikhulu | B522L | 250 kW / 522 kWh / 375 A / 240 kW PV |
| Umsebenzi wesityalo sele ukwamakhulu e-kW kwaye amandla afikelele kwi-1.5-2 MWh. | Usapho lwe-B2M6L | 750 okanye 1000 kW, 1130 okanye 1500 A, 1.5 okanye 2 MWh |
Uluhlu olupheleleyo lwezinto zangaphandle lulandelayo KRL C&I iinkqubo zokugcina amandla. Uthelekiso olubanzi lwemodeli luyagqitywa kwi Isikhokelo sokukhetha iinkqubo zokugcina amandla zorhwebo nezoshishino.
Iindawo ezixhomekeke kakhulu kwidizili zingaqhubeka nge Ugcino lwebhetri yezoshishino lokunciphisa iindleko zedizili. Izityalo ezilinganiselwe ubungakanani ngenxa yokunqunyanyiswa kobusuku bonke zingasebenzisa Ukuphinda kusebenze kombane kwifektri emva kwesithuba esingumnyama, ngo-2 kusasa..
