I-Battery Energy Storage System (BESS) yinkqubo yebhetri enkulu esekelwe kuqhagamshelwano lwegridi, esetyenziselwa ukugcina umbane kunye namandla. Idibanisa iibhetri ezininzi kunye ukwenza isixhobo sokugcina amandla esidibeneyo.
1. Iseli yebhetri: Njengenxalenye yenkqubo yebhetri, iguqula amandla ekhemikhali abe ngamandla ombane.
2. IModyuli yeBattery: Iqulunqwe ngamacandelo amaninzi kunye neeseli zebhetri ezidibeneyo ezihambelanayo, iquka iModyuli yoLawulo lweBattery System (MBMS) ukujonga ukusebenza kweeseli zebhetri.
3. I-Battery Cluster: Isetyenziselwa ukuhlalisa iimodyuli ezininzi ezidibeneyo kunye neeyunithi zokuKhusela iBattery (BPU), eyaziwa ngokuba ngumlawuli weqela lebhetri. Inkqubo yoLawulo lwebhetri (BMS) yeqela lebhetri ijonga amandla ombane, ubushushu, kunye nemo yokutshaja kweebhetri ngelixa ilawula imijikelo yokutshaja nokukhupha.
4. Isingxobo sokuGcina amandla: Inokuthwala amaqela ebhetri adityanisiweyo amaninzi adityanisiweyo kwaye inokuxhotyiswa namanye amacandelo ongezelelweyo okulawula okanye ukulawula indawo yangaphakathi yesingxobo.
5. Inkqubo yokuguqulwa kwamandla (i-PCS): Umbane othe ngqo (DC) owenziwe ngamabhetri uguqulwa ube yi-alternating current (AC) nge-PCS okanye i-bidirectional inverters yokudluliselwa kwigridi yamandla (izixhobo okanye abasebenzisi bokugqibela). Xa kuyimfuneko, le nkqubo inokukhupha amandla kwigridi ukuze ihlawule iibhetri.
Uthini umgaqo osebenzayo weeNkqubo zokuGcina amandla eBhetri (BESS)?
Umgaqo osebenzayo weBattery Energy Storage System (BESS) ikakhulu ibandakanya iinkqubo ezintathu: ukutshaja, ukugcina, kunye nokukhupha. Ngexesha lenkqubo yokutshaja, i-BESS igcina amandla ombane kwibhetri ngomthombo wamandla wangaphandle. Ukuphunyezwa kunokuba yinto yangoku ngokuthe ngqo okanye i-alternating current, ngokuxhomekeke kuyilo lwenkqubo kunye neemfuno zesicelo. Xa kukho amandla aneleyo abonelelwa ngumthombo wamandla angaphandle, i-BESS iguqula amandla angaphezulu kumandla ekhemikhali kwaye iwagcine kwiibhetri ezinokutshajwa kwakhona kwifomu ehlaziyiweyo ngaphakathi. Ngethuba lokugcinwa kwenkqubo, xa kungabikho ngokwaneleyo okanye akukho sibonelelo sangaphandle esikhoyo, i-BESS igcina amandla agcinwe ngokupheleleyo kwaye igcina ukuzinza kwayo ukusetyenziswa kwexesha elizayo. Ngexesha lenkqubo yokukhupha, xa kukho imfuneko yokusebenzisa amandla agciniweyo, i-BESS ikhupha isixa esifanelekileyo samandla ngokwemfuno yokuqhuba izixhobo ezahlukeneyo, iinjini okanye ezinye iindlela zemithwalo.
Ziziphi iingenelo kunye nemingeni yokusebenzisa i-BESS?
