Izitsha zekhebula ze-voltage ephezulu (HV)zidlala indima ebalulekile ekudlulisweni kwamandla okuphumelelayo emabangeni amade. Eyaziwa nangokuthi izixhumi, lawa masokhethi axhumanisa izintambo ezinamandla aphezulu ezinhlotsheni ezahlukahlukene zokusebenza, okuhlanganisa amanethiwekhi okusabalalisa amandla, izinhlelo zamandla avuselelekayo kanye nengqalasizinda yezimboni. Kulesi sihloko, sizohlola ukubaluleka kwamasokhethi ekhebula ane-voltage ephezulu, izici zawo eziyinhloko, nokuthi anikela kanjani ekudlulisweni kwamandla okuphumelelayo kakhudlwana.
Ukubaluleka kwezisekelo zekhebula ezine-voltage ephezulu:
Amasokhethi ekhebula anogesi ophezulu ayisixhumanisi esibalulekile phakathi kweziteshi zikagesi nabasebenzisi bokugcina, okuqinisekisa ukudluliswa kwamandla okuthembekile nokusebenzayo. Nazi izizathu ezimbalwa ezenza lezi zindawo zokuxhuma zibaluleke:
Uxhumano Oluphephile:
Amasokhethi ekhebula anogesi ophezulu ahlinzeka ngokuxhumana okuphephile phakathi kwezintambo ezinogesi ophezulu, okunciphisa ingozi yamaphutha kagesi, ukuphazamiseka kwamandla kanye nokulahlekelwa amandla ngesikhathi sokudlulisa.
Ukuzivumelanisa nezimo:
Zivumela izintambo ukuthi zixhunywe futhi zinqanyulwe, okwenza kube lula ukufaka, ukunakekela nokuthuthukisa izinhlelo zamandla, okubaluleke kakhulu ekuzivumelaniseni nezidingo zamandla ezishintshayo.
Ukuphathwa Kwemithwalo:
Amasokhethi ekhebula anogesi ophezulu ayakwazi ukusabalalisa ugesi kusuka emithonjeni ehlukene kuya ezindaweni eziningi, okuvumela ukuphathwa komthwalo okuphumelelayo kanye nokusebenza kahle kwegridi.
Izici eziyinhloko zamasokhethi ekhebula ane-voltage ephezulu:
Ukuqinisekisa ukudluliswa kwamandla okuthembekile nokuphumelelayo, amasokhethi ekhebula ane-voltage ephezulu anezici eziningana eziyisisekelo. Lezi zici zithuthukisa ukusebenza nokuphepha kohlelo lonke lwamandla.
Ezinye izici ezibalulekile zifaka:
Isilinganiso se-Voltage Ephakeme:
Izitsha zekhebula ezinamandla aphezuluzenzelwe ukuphatha amazinga aphezulu kagesi, ngokuvamile asukela ku-66 kV kuya ku-500 kV nangaphezulu, ukuqinisekisa ukudluliswa kwamandla okuphephile nokuphumelelayo.
Ukwakhiwa Okuqinile:
Lezi zindawo zokufaka amanzi zakhiwe ukuze zikwazi ukumelana nezimo zemvelo ezinzima, okuhlanganisa amazinga okushisa aphezulu, umswakama, kanye nokuchayeka kumakhemikhali, okuqinisekisa ukuthembeka nokuqina kwesikhathi eside.
Ukuvikela kanye Nokuvikela:
Amasokhethi ekhebula anogesi ophezulu asebenzisa izinto zokuvikela nokuvikela ukuvimbela ukuvuza nokuqinisekisa ukudluliswa kwamandla okuphephile, okunciphisa ingozi yezingozi zikagesi kanye nezingozi.
Izici zokutholwa kwamaphutha kanye nokuphepha:
Amanye amasokhethi ekhebula anogesi ophezulu afakwe izinhlelo zokuthola amaphutha ezingabona futhi zihlukanise ngokushesha noma yimaphi amaphutha kagesi, okwandisa ukuphepha nokunciphisa isikhathi sokungasebenzi.
Thuthukisa ukusebenza kahle kokudlulisa amandla:
Amasokhethi ekhebula ane-voltage ephezulu adlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kokudluliselwa kwamandla. Umklamo wawo osebenzayo kanye nokusebenza kwawo kusiza ukufeza imigomo elandelayo:
Nciphisa ukulahleka kwamandla:
Amasokhethi ekhebula ane-voltage ephezulu, uma efakwe futhi egcinwa kahle, anganciphisa ukulahleka kwamandla ngesikhathi sokudlulisa, aqinisekise ukulethwa kwamandla okuphumelelayo futhi anciphise imfucuza yamandla iyonke.
Ukuthembeka kwesistimu okuthuthukisiwe:
Izingodo zekhebula ezinamandla aphezulu ezithembekile zisiza ukwandisa isikhathi sokusebenza kwesistimu ngokuvimbela amaphutha kagesi kanye nokwehluleka, ukunciphisa isikhathi sokungasebenzi kanye nokwandisa ukuthembeka kwenethiwekhi yokusabalalisa amandla. Khuthaza ukuhlanganiswa kwamandla avuselelekayo kugridi: Izingodo zekhebula ezinamandla aphezulu zidlala indima ebalulekile ekuhlanganisweni kwamandla avuselelekayo kugridi. Ngokuxhumanisa izikhungo zokukhiqiza amandla avuselelekayo kugridi, lezi zingodo zivumela ukusetshenziswa kahle kwamandla ahlanzekile nasimeme.
Ekuphetheni:
Izitsha zekhebula ezinamandla aphezuluzidlala indima ebalulekile ekuhlinzekeni ngokudluliselwa kwamandla okuphephile nokusebenzayo emabangeni amade. Lezi zindawo zokukhipha amandla zinezilinganiso zamandla aphezulu, ukwakhiwa okuqinile, kanye nezici ezithuthukisiwe ukuqinisekisa ukuthembeka, ukunciphisa ukulahlekelwa amandla, kanye nokwandisa ukusebenza kahle kokudluliselwa kwamandla. Njengoba intuthuko yezobuchwepheshe iqhubeka nokubumba imboni yamandla, amasokhethi ekhebula ane-voltage ephezulu azohlala eyisici esibalulekile, enikeza ukunikezwa kwamandla okusimeme nokuthembekile kwezinhlelo zokusebenza ezahlukahlukene.
