Njengoba uhlelo lwamandla lukhula, isikali segridi siyaqhubeka nokukhula, okuholela ezidingweni eziphakeme zokuxhumana kwamandla. Amabhethri, njengengxenye ebalulekile yesistimu yamandla e-telecom, anomthelela oqondile ekuthembekeni kokuxhumana kwamandla. Ukuqhuba ukuhlolwa kwamandla ngokushaja nokukhipha imijikelezo kuyindlela ebalulekile yokugcina ukusebenza kwebhethri nokwelula impilo yebhethri. Ngokwemithethonqubo yokugcinwa kwesistimu yamandla e-telecom, amabhethri adinga ukulungiswa njalo. Uma kuqhathaniswa nezindlela ezifana nokulinganisa i-terminal voltage kanye nokuhlola ukumelana kwangaphakathi, ukuhlolwa kwamandla kunikeza ukunemba okukhulu. Amabhethri asanda kufakwa adinga ukuhlolwa kokukhishwa komthamo ogcwele, okulandelwa ukuhlolwa kokukhishwa komthamo waminyaka yonke. Kumabhethri asebenza iminyaka emine, ukuhlolwa kwamandla okuthatha ingxenye yonyaka kuyadingeka. Uma ibhethri lehluleka ukuthola u-80% womthamo walo olinganiselwe ngemva kokuhlolwa okuthathu okulandelanayo, kufanele kucatshangelwe ukushintshwa.
Njengamanje, izikimu ezintathu ezijwayelekile zokuhlola umthamo webhethri zisetshenziswa kabanzi kubunjiniyela: i-dummy load, i-DC/AC conversion, kanye ne-DC/DC boosted voltage schemes.
Idivayisi yokuhlola umthamo ngokuyinhloko iqukethe imojuli yesekethe yebhethri ye-DC/DC enefrikhwensi ephezulu, imvamisa ephezulu yebhethri ye-DC/DC iphakethe lemojuli yokushaja yamanje, othintana nabo, nama-diode. Uhlelo lusebenza ezifundeni ezintathu: ishaja entantayo ebekwe eceleni, ukukhishwa komthamo, kanye nokushajwa kwamanje okungashintshi. Lezi zifundazwe zakha umjikelezo wokusebenza ophelele wokuhlolwa kwamandla.
Isimo sokushaja esintantayo esilindile
Esimeni sokushaja esintantayo, isixhumi se-NC i-K1 sivaliwe, futhi i-NO contactor KM iyavula. Ibhethri liku-inthanethi, nesilungisisi sinikeza amandla kukho kokubili iphakethe lebhethri nomthwalo. Esimeni sokunqamuka kwamandla okungalindelekile, iphakethe lebhethri linganikeza amandla ngokuqondile ekulayisheni, liqinisekise ukunikezwa kwamandla okungaphazamiseki.
Umfanekiso 1: Iphakethe Lebhethri Esimeni Sokushaja Esintantayo Esilindile
I-Capacity Discharge State
Ngesikhathi sokukhipha umthamo, i-NC contactor K1 iyavula, futhi i-NO contactors i-KM ne-KC iyavala. Iphakethe lebhethri le-DC/DC eline-frequency ephezulu liyasebenza. Ibhethri likhuliswa isekethe ye-DC/DC kuya ku-voltage ephakeme kancane kune-voltage yokulungisa, ngaleyo ndlela imiselela isilungisi ekunikezeni amandla kumthwalo. Lapho kuqedwa ukukhishwa, isistimu ishintshela ngokuzenzakalelayo ekushajweni kwamanje okungaguquki, kanye nemojula yesifunda yokushaja eqhubekayo isebenza.
Umfanekiso 2: Iphakethe Lebhethri Esimeni Sokukhipha Ikhono
Isimo Senkokhelo Yamanje Eqhubekayo
Ngemuva kokukhishwa kwamandla, isistimu ishintshela ngokuzenzakalelayo ekushajweni kwamanje okungashintshi. Ibhethri le-DC/DC elinemvamisa ephezulu lipakisha imojuli yesekethe yeshaja yamanje eqhubekayo iyasebenza, ilungisa ngokuzenzakalelayo ukushaja kube ivelu elisethiwe kuyilapho kusetshenziswa isilungisi sangempela sokushajwa kwamanje. Njengoba i-voltage yebhethri ikhuphuka ngasekupheleni kwenqubo yokushaja, amandla okushaja ayehla. Uma okwamanje kwehla ngaphansi komkhawulo omisiwe wedivayisi, isistimu iqeda ngokuzenzakalelayo inqubo yokushaja yamanje engashintshi. I-NC contactor K1 iyavala, imise imvamisa ephezulu yebhethri ye-DC/DC module yesekethe yokushajwa yamanje, futhi inqamule i-KM ne-KC. Iphakethe lebhethri libe selibuyela esimweni sokushajwa esintantayo esilindile.
Umfanekiso 3: Iphakethe Lebhethri Esimeni Sokushajwa Kwamanje
Okungenhla kuchaza ukuqaliswa kwesistimu yokuhlola umthamo ngokusekelwe ku-DC/DC. Isixazululo samukelwa kabanzi ngabakhiqizi bezimboni. Isibonelo, i-DFUN iklame isixazululo esibanzi sokuhlola umthamo ku-inthanethi esikude, esifinyelela ukulawula okumaphakathi kwamasayithi ahlakazekile ukude, okonga isikhathi, okulula, futhi okuthembekile.
Isixazululo sokuhlola umthamo we-DFUN , ngaphezu komsebenzi wokuhlola umthamo, sihlanganisa ukuqapha kwebhethri ngesikhathi sangempela nezici zokwenza kusebenze ibhethri, ukunika amandla ukuqapha okukude, ubusuku nemini nokugcinwa kwamaphakethe ebhethri.
