Kubva pane tekinoroji yekuona, kutora ± 800 kV UHV DC kutapurirana, iyo yepakati yemutsara haidi kudonhedza poindi, iyo inogona kutumira huwandu hukuru hwesimba zvakananga kunzvimbo huru yekuremedza;muchiitiko che AC / DC parallel transmission, inogona kushandisa bilateral frequency modulation kuti ibudirire inhibitidza nharaunda yakaderera-frequency oscillation, uye kuvandudza muganho wenguva pfupi (simba) kugadzikana kwechikamu chemuchinjikwa;uye gadzirisa dambudziko rekupfuura pfupi-circuit ikozvino yekugamuchira kukuru kwekupedzisira kwegetsi remagetsi.Kutora 1000kV AC kutapurirana, yepakati inogona kudonhedzwa negridi basa;kusimbisa grid kuti itsigire yakakura-yakakura DC magetsi ekufambisa;kugadzirisa zvakanyanya matambudziko enguva pfupi-sekiti ikozvino inodarika mwero wegedhi hombe yekugashira uye yakaderera kutapurirana kwe500kV mutsara, uye optimize chimiro chemagetsi grid.
Panyaya yekutapurirana simba uye kugadzikana kwekuita, uchishandisa ± 800 kV UHV DC kutapurirana, kugadzikana kwekutapurirana kunoenderana neanoshanda mapfupi dunhu reshiyo (ESCR) uye inoshanda inertia isingachinjiki (Hdc) yegidhi pakupera kwekugamuchira, pamwe nechimiro che grid pamagumo ekutumira.Kugamuchira 1000 kV AC kutapurirana, simba rekutapurirana rinoenderana nepfupi-yedunhu simba rega rega retsigiro poindi uye chinhambwe chetambo yekutapurirana (chinhambwe chiri pakati pemadonhwe ekudonha ezviteshi zviviri zviri padyo);kugadzikana kwekufambisa (synchronization capacity) kunoenderana nehukuru hwekona yemagetsi panzvimbo yekushanda (musiyano pakati pemakona emagetsi pamagumo maviri emutsara).
Kubva pakuona kwezvinhu zvakakosha zvetekinoroji zvinoda kutariswa, kushandiswa kwe ± 800 kV UHV DC kutapurirana kunofanirwa kutarisa kune static reactive simba chiyero uye dynamic reactive simba backup uye kugadzikana kwevoltage yekugamuchira kupera kwegridi, uye inofanirwa kutarisa pane system. voltage kuchengetedza nyaya dzinokonzerwa nekutadza panguva imwe chete yekuchinja kwechikamu mune yakawanda-kudonha DC feeder system.Iko kushandiswa kwe1000 kV AC kutapurirana kunofanirwa kutarisisa kune AC system chikamu kugadziridzwa uye voltage regulation matambudziko kana oparesheni maitiro achinjwa;kubhadhara kune zvinetso zvakadai sekuendeswa kwemasimba makuru muzvikamu zvisina kusimba pasi pemamiriro ekukanganisa kwakakomba;uye kutarisisa njodzi dzakavanzwa dzenjodzi dzemagetsi munzvimbo huru uye matanho adzo ekudzivirira.
