Itandukaniro riri hagati ya DC na AC transmission

Mu rwego rwa tekiniki, gukoresha transmission ya ±800 kV UHV DC, hagati y'umurongo ntabwo hakenewe ko hamanuka, bishobora kohereza ingufu nyinshi mu buryo butaziguye mu kigo kinini cy'umutwaro; mu gihe transmission ya AC/DC igendana, ishobora gukoresha modulation ya frequency zombie kugira ngo ihagarike neza oscillation y'akarere ya frequency low, no kunoza umupaka w'igihe gito (dynamic) cy'igice cyambukiranya; no gukemura ikibazo cyo kurenza umuyoboro mugufi w'impera nini yakira amashanyarazi. Gukoresha transmission ya AC ya 1000kV, hagati hashobora kumanuka hakoreshejwe grid function; gukomeza grid kugira ngo ishyigikire transmission nini ya DC; gukemura ibibazo by'umuyoboro mugufi urenze urugero rwa grid nini yakira amashanyarazi n'ubushobozi buke bwo kohereza amashanyarazi bwa 500kV, no kunoza imiterere ya grid power.

Ku bijyanye n'ubushobozi bwo kohereza no guhagarara neza, hakoreshejwe transmission ya ± 800 kV UHV DC, guhagarara neza kw'ihererekanya ry'amashanyarazi biterwa n'ikigereranyo cy'amashanyarazi magufi (ESCR) n'uburyo ntarengwa bwo guhagarara neza (Hdc) by'urusobe rw'amashanyarazi ku mpera y'aho rugereye, ndetse n'imiterere y'urusobe rw'amashanyarazi ku mpera yo kohereza. Gukoresha transmission ya 1000 kV AC, ubushobozi bwo kohereza bw'amashanyarazi bushingiye ku bushobozi bwo guhagarara neza bw'urusobe rw'amashanyarazi buri gice cy'inkunga y'umurongo n'intera y'umurongo wo kohereza (intera iri hagati y'aho amashanyarazi amanuka y'ibice bibiri byegeranye); guhagarara neza kw'ihererekanya ry'amashanyarazi (ubushobozi bwo guhuza) biterwa n'ubunini bw'inguni y'amashanyarazi ku gice cy'akazi (itandukaniro riri hagati y'inguni z'amashanyarazi ku mpera ebyiri z'umurongo).

Ukurikije ibibazo by'ingenzi bya tekiniki bikeneye kwitabwaho, ikoreshwa rya transmission ya ±800 kV UHV DC rigomba kwibanda ku kuringaniza ingufu zihindagurika hamwe no gusimbuza ingufu zihindagurika hamwe no guhagarara k'amashanyarazi ku gice cyakira umuriro, kandi rigomba kwibanda ku bibazo by'umutekano w'amashanyarazi biterwa no gucika burundu kw'impinduka mu buryo bwa DC feeder. Ikoreshwa rya transmission ya 1000 kV AC rigomba kwibanda ku bibazo byo guhindura imiterere y'amashanyarazi no kugenzura amashanyarazi mu gihe uburyo bwo gukora bwahindutse; kwibanda ku bibazo nko kohereza ingufu nyinshi mu bice bike cyane mu bihe bikomeye; no kwibanda ku ngaruka zihishe z'impanuka zo mu gace kanini n'ingamba zo kuzirinda.
