Itandukaniro hagati ya DC na AC

Uhereye kuri tekiniki ya tekiniki, gufata ± 800 kV UHV DC yoherejwe, hagati yumurongo ntukeneye kugabanuka, ushobora kohereza imbaraga nyinshi muburyo bunini bwo kwikorera ikigo;kubijyanye na AC / DC ihererekanyabubasha, irashobora gukoresha modulisiyo yuburyo bubiri kugirango ihagarike neza ihindagurika ry’akarere gake, kandi itezimbere imipaka yigihe gito (dinamike) itambutse;kandi ukemure ikibazo cyo kurenga imiyoboro ngufi ya nini yakira amaherezo ya gride.Kwemeza 1000kV AC yoherejwe, hagati irashobora kugabanuka hamwe na gride imikorere;gushimangira gride kugirango ishyigikire amashanyarazi manini ya DC;gukemura byimazeyo ibibazo byumuyoboro mugari urenze urwego runini rwakira amaherezo ya gride nubushobozi buke bwohereza umurongo wa 500kV, no kunoza imiterere ya gride.

Kubijyanye nubushobozi bwo kohereza no gukora neza, ukoresheje ± 800 kV UHV DC yohereza, ituze ryogukwirakwiza biterwa nigipimo kigufi cyumuzunguruko (ESCR) hamwe nubusembure bukora neza (Hdc) bwa gride kumpera yakira, kimwe nuburyo bwa Urusobekerane Kuri Kohereza.Kwemeza 1000 kV ya AC, ubushobozi bwo kohereza biterwa nubushobozi buke bwumuzunguruko wa buri nkunga yumurongo hamwe nintera yumurongo wohereza (intera iri hagati yigitonyanga cyibice bibiri byegeranye);ihererekanyabubasha (ubushobozi bwa syncronisation) biterwa nubunini bwinguni zingufu aho ikorera (itandukaniro riri hagati yinguni zingufu kumpera zombi zumurongo).

Urebye ibibazo byingenzi bya tekiniki bikeneye kwitabwaho, ikoreshwa rya ± 800 kV UHV DC ikwirakwiza igomba kwibanda ku buringanire bw’ingufu zidasanzwe hamwe n’ingufu zidasanzwe zisubizwa inyuma hamwe n’umuvuduko w’amashanyarazi wakira impera ya gride, kandi igomba kwibanda kuri sisitemu ibibazo byumutekano wa voltage biterwa no kunanirwa icyarimwe guhinduranya icyiciro muri sisitemu yo kugaburira DC nyinshi.Imikoreshereze ya 1000 kV ya AC igomba kwitondera gahunda ya AC ya sisitemu yo guhindura no gukemura ibibazo bya voltage mugihe imikorere yimikorere ihinduwe;kwitondera ibibazo nko guhererekanya ingufu nyinshi mubice bigoye cyane mubihe bikomeye;no kwitondera akaga kihishe impanuka nini yibasiwe ningamba zo gukumira.
