Inkqubo Yokugcina Amandla Ebhetri (i-BESS) yinkqubo enkulu yebhetri esekelwe kuqhagamshelo lwegridi, esetyenziselwa ukugcina umbane kunye namandla. Idibanisa iibhetri ezininzi kunye ukwenza isixhobo sokugcina amandla esidibeneyo.
1. Iseli yebhetri: Njengenxalenye yenkqubo yebhetri, iguqula amandla eekhemikhali abe ngamandla ombane.
2. IModyuli yeBhetri: Yenziwe ngochungechunge oluninzi kunye neeseli zebhetri ezidityanisiweyo ngaxeshanye, iquka iModyuli yeNkqubo yoLawulo lweBhetri (MBMS) yokujonga ukusebenza kweeseli zebhetri.
3. Iqela leebhetri: Lisetyenziselwa ukwamkela iimodyuli ezininzi ezidityaniswe ngochungechunge kunye neeYunithi zoKhuseleko lweebhetri (i-BPU), ezaziwa ngokuba yi-battery cluster controller. Inkqubo yoLawulo lweebhetri (i-BMS) yeqela leebhetri ijonga i-voltage, ubushushu, kunye nemeko yokutshaja kweebhetri ngelixa ilawula imijikelo yazo yokutshaja nokukhupha ibhetri.
4. Isikhongozeli sokugcina amandla: Sinokuthwala amaqela eebhetri amaninzi aqhagamshelwe ngaxeshanye kwaye sinokuxhotyiswa ngezinye izinto ezongezelelweyo zokulawula okanye ukulawula imeko-bume yangaphakathi yesikhongozeli.
5. Inkqubo yoGuqulo lwaMandla (PCS): Umbane othe ngqo (DC) oveliswa ziibhetri uguqulwa ube ngumbane otshintshanayo (AC) ngePCS okanye ii-inverters ezibhekisa kwicala elinye ukuze zidluliselwe kwigridi yamandla (izixhobo okanye abasebenzisi bokugqibela). Xa kuyimfuneko, le nkqubo inokukhupha umbane kwigridi ukuze itshaje iibhetri.
Yintoni umgaqo osebenzayo weeNkqubo zokugcina amandla ebhetri (BESS)?
Umgaqo osebenzayo weNkqubo yokuGcina Amandla eBhetri (i-BESS) uquka ikakhulu iinkqubo ezintathu: ukutshaja, ukugcina, kunye nokukhupha itshaja. Ngexesha lenkqubo yokutshaja, i-BESS igcina amandla ombane kwibhetri ngokusebenzisa umthombo wamandla wangaphandle. Ukuphunyezwa kungaba ngumbane othe ngqo okanye umbane otshintshanayo, kuxhomekeke kuyilo lwenkqubo kunye neemfuno zesicelo. Xa kukho amandla aneleyo anikezelwa ngumthombo wamandla wangaphandle, i-BESS iguqula amandla agqithisileyo abe ngamandla eekhemikhali kwaye iwagcine kwiibhetri ezinokutshaja kwakhona ngendlela ehlaziyekayo ngaphakathi. Ngexesha lenkqubo yokugcina, xa kungekho sibonelelo sangaphandle esaneleyo okanye kungekho sibonelelo sangaphandle esifumanekayo, i-BESS igcina amandla agciniweyo agcweleyo kwaye igcina uzinzo lwayo ukuze isetyenziswe kwixesha elizayo. Ngexesha lenkqubo yokukhupha itshaja, xa kukho imfuneko yokusebenzisa amandla agciniweyo, i-BESS ikhupha isixa esifanelekileyo samandla ngokwemfuno yokuqhuba izixhobo ezahlukeneyo, iinjini okanye ezinye iintlobo zemithwalo.
Ziziphi iingenelo kunye nemingeni yokusebenzisa i-BESS?
I-BESS inokubonelela ngeenzuzo ezahlukeneyo kunye neenkonzo kwinkqubo yamandla, ezinje ngezi:
1. Ukuphucula ukuhlanganiswa kwamandla avuselelekayo: I-BESS inokugcina amandla avuselelekayo agqithisileyo ngexesha lokuveliswa okuphezulu kunye nemfuno ephantsi, kwaye iwakhulule ngexesha lokuveliswa okuphantsi kunye nemfuno ephezulu. Oku kunokunciphisa ukuncitshiswa komoya, kuphucule izinga lokusetyenziswa kwawo, kwaye kuphelise ukungabikho kwawo kunye nokuguquguquka.
2. Ukuphucula umgangatho wamandla kunye nokuthembeka: I-BESS inokubonelela ngempendulo ekhawulezayo neguquguqukayo kwi-voltage kunye ne-frequency changes, i-harmonics, kunye neminye imiba yomgangatho wamandla. Ingasebenza njengomthombo wamandla oxhasayo kwaye ixhase umsebenzi wokuqalisa omnyama ngexesha lokucima kwegridi okanye iimeko ezingxamisekileyo.
3. Ukunciphisa imfuno ephezulu: I-BESS ingatshaja ngexesha elingengo xinzelelo xa amaxabiso ombane ephantsi, kwaye ikhuphe ngexesha elingengo xinzelelo xa amaxabiso ephezulu. Oku kunokunciphisa imfuno ephezulu, kunciphise iindleko zombane, kwaye kulibazise isidingo sokwandiswa kwamandla okuvelisa okanye ukuphuculwa kothumelo.
4. Ukunciphisa ukukhutshwa kwegesi ezibangela ukufudumala komhlaba: I-BESS inokunciphisa ukuxhomekeka ekuveliseni amafutha asekelwe kwifosili, ingakumbi ngexesha lexesha elixakekileyo, ngelixa inyusa isabelo samandla avuselelekayo kumxube wamandla. Oku kunceda ukunciphisa ukukhutshwa kwegesi ezibangela ukufudumala komhlaba kunye nokunciphisa impembelelo yotshintsho lwemozulu.
Nangona kunjalo, iBESS ikwajongene nemingeni ethile, efana nale:
1. Ixabiso eliphezulu: Xa kuthelekiswa neminye imithombo yamandla, i-BESS isabiza kakhulu, ingakumbi ngokweendleko zenkunzi, iindleko zokusebenza nokugcinwa, kunye neendleko zomjikelo wobomi. Ixabiso le-BESS lixhomekeke kwizinto ezininzi ezifana nohlobo lwebhetri, ubungakanani benkqubo, ukusetyenziswa kwayo, kunye neemeko zemarike. Njengoko ubuchwepheshe bukhula kwaye bukhula, ixabiso le-BESS kulindeleke ukuba lehle kwixesha elizayo kodwa lisenokuba ngumqobo ekwamkelweni ngokubanzi.
2. Imiba yokhuseleko: I-BESS ibandakanya umbane ophezulu, umbane omkhulu, kunye nobushushu obuphezulu obunokubangela iingozi ezinje ngeengozi zomlilo, ukuqhuma, ukutshayiswa kombane njl.njl. I-BESS ikwanazo nezinto eziyingozi ezifana neesinyithi, ii-asidi kunye nee-electrolytes ezinokubangela iingozi zokusingqongileyo kunye nempilo ukuba aziphathwanga okanye azilahlwanga ngokufanelekileyo. Imigangatho yokhuseleko engqongqo, imigaqo kunye neenkqubo ziyafuneka ukuqinisekisa ukusebenza ngokukhuselekileyo kunye nolawulo lwe-BESS.
5. Impembelelo yokusingqongileyo: I-BESS inokuba nemiphumo emibi kwindalo esingqongileyo kuquka ukuphelelwa zizixhobo, imiba yokusetyenziswa komhlaba, iingxaki zokusetyenziswa kwamanzi, iingxaki zokuveliswa kwenkunkuma, kunye neenkxalabo zongcoliseko. I-BESS ifuna ubungakanani obukhulu bezinto ezikrwada ezifana ne-lithium, i-cobalt, i-nickel, ubhedu njl.njl., ezinqabileyo kwihlabathi liphela kwaye zingasasazwa ngokulinganayo. I-BESS ikwasebenzisa amanzi kunye nomhlaba ukuze kufakwe imveliso yemigodi, kwaye kusetyenziswe. I-BESS ivelisa inkunkuma kunye nokukhutshwa komoya kuyo yonke ijikelezo layo lobomi elinokuchaphazela umgangatho womhlaba wamanzi omoya. Iimpembelelo zokusingqongileyo kufuneka ziqwalaselwe ngokwamkela iindlela ezizinzileyo zokunciphisa iziphumo zazo kangangoko kunokwenzeka.
Ziziphi iindlela eziphambili zokusetyenziswa kunye neendlela zokusetyenziswa kwe-BESS?
I-BESS isetyenziswa kakhulu kumashishini ahlukeneyo kunye nezicelo, ezinje ngokuveliswa kombane, izibonelelo zokugcina amandla, imigca yokuhambisa nokuhambisa kwinkqubo yamandla, kunye neenkqubo zombane zezithuthi kunye nezolwandle kwicandelo lezothutho. Ikwasetyenziswa kwiinkqubo zokugcina amandla ebhetri kwizakhiwo zokuhlala kunye nezorhwebo. Ezi nkqubo zinokuhlangabezana neemfuno zokugcina amandla angaphezulu kwaye zibonelele ngomthamo wokuxhasa ukunciphisa ukuxinana kwimigca yokuhambisa nokuhambisa ngelixa zithintela ukuxinana kwinkqubo yokuhambisa. I-BESS idlala indima ebalulekileyo kwiigridi ezincinci, eziziinethiwekhi zamandla ezisasazwayo eziqhagamshelwe kwigridi ephambili okanye ezisebenza ngokuzimeleyo. Iigridi ezincinci ezizimeleyo ezikwiindawo ezikude zinokuxhomekeka kwi-BESS edityaniswe nemithombo yamandla ahlaziyekayo ngamaxesha athile ukufezekisa ukuveliswa kombane okuzinzileyo ngelixa zinceda ukuphepha iindleko eziphezulu ezinxulumene neenjini zedizili kunye nemiba yongcoliseko lomoya. I-BESS iza ngobukhulu obahlukeneyo kunye nolwakhiwo, ifanelekile kwizixhobo zasekhaya ezincinci kunye neenkqubo ezinkulu zoncedo. Zingafakwa kwiindawo ezahlukeneyo kubandakanya amakhaya, izakhiwo zorhwebo, kunye nezikhululo ezincinci. Ukongeza, zinokusebenza njengemithombo yamandla yokuxhasa engxamisekileyo ngexesha lokucima kombane.
Ziziphi iintlobo ezahlukeneyo zeebhetri ezisetyenziswa kwi-BESS?
1. Iibhetri ze-lead-acid zezona ntlobo zebhetri zisetyenziswa kakhulu, eziquka iipleyiti ze-lead kunye ne-sulfuric acid electrolyte. Zixatyiswa kakhulu ngexabiso lazo eliphantsi, ubuchwepheshe obuvuthiweyo, kunye nobomi obude, ezisetyenziswa kakhulu kwiindawo ezifana neebhetri zokuqala, imithombo yamandla engxamisekileyo, kunye nokugcinwa kwamandla amancinci.
