Los ntawm qhov kev pom ntawm kev siv tshuab, kev siv ± 800 kV UHV DC kis, qhov nruab nrab ntawm txoj kab tsis tas yuav poob qis, uas tuaj yeem xa ntau lub zog ncaj qha mus rau qhov chaw thauj khoom loj; nyob rau hauv cov ntaub ntawv ntawm AC / DC kis sib luag, nws tuaj yeem siv ob sab zaus modulation kom zoo inhibit qhov oscillation qis zaus hauv cheeb tsam, thiab txhim kho qhov txwv ntawm kev ruaj khov ib ntus (dynamic) ntawm qhov hla-section; thiab daws qhov teeb meem ntawm kev dhau qhov luv luv tam sim no ntawm qhov kawg loj ntawm lub zog hluav taws xob grid. Kev siv 1000kV AC kis, qhov nruab nrab tuaj yeem poob nrog lub luag haujlwm grid; txhawb nqa lub grid los txhawb kev xa hluav taws xob DC loj; daws qhov teeb meem ntawm qhov luv luv tam sim no dhau qhov tus qauv ntawm qhov kawg loj grid thiab lub peev xwm xa qis ntawm 500kV kab, thiab ua kom zoo dua cov qauv ntawm lub zog hluav taws xob grid.
Hais txog lub peev xwm kis tau thiab kev ruaj khov, siv ± 800 kV UHV DC kis tau, kev ruaj khov kis tau nyob ntawm qhov piv ntawm lub voj voog luv luv (ESCR) thiab qhov tsis hloov pauv zoo (Hdc) ntawm lub grid ntawm qhov kawg tau txais, nrog rau cov qauv ntawm lub grid ntawm qhov kawg xa. Kev siv 1000 kV AC kis tau, lub peev xwm kis tau nyob ntawm lub peev xwm luv luv ntawm txhua qhov chaw txhawb nqa ntawm kab thiab qhov deb ntawm kab kis tau (qhov deb ntawm cov ntsiab lus poob ntawm ob lub chaw sib ze); kev ruaj khov kis tau (lub peev xwm sib dhos) nyob ntawm qhov loj ntawm lub kaum sab xis fais fab ntawm qhov chaw ua haujlwm (qhov sib txawv ntawm lub kaum sab xis fais fab ntawm ob qhov kawg ntawm kab).
Los ntawm qhov kev xav ntawm cov teeb meem tseem ceeb uas xav tau kev saib xyuas, kev siv ± 800 kV UHV DC kis tau tus mob yuav tsum tsom mus rau qhov sib npaug ntawm lub zog reactive thiab lub zog rov qab dynamic thiab qhov ruaj khov ntawm qhov kawg ntawm lub grid, thiab yuav tsum tsom mus rau qhov teeb meem kev ruaj ntseg ntawm lub cev muaj zog uas tshwm sim los ntawm kev ua tsis tiav ntawm kev hloov theem hauv lub cev muaj zog DC feeder ntau-poob. Kev siv 1000 kV AC kis tau tus mob yuav tsum them sai sai rau qhov teeb meem kev hloov kho theem ntawm lub cev muaj zog AC thiab kev tswj hwm voltage thaum hloov hom kev ua haujlwm; them sai sai rau cov teeb meem xws li kev hloov pauv ntawm lub zog siab hauv cov ntu tsis muaj zog nyob rau hauv cov xwm txheej loj; thiab them sai sai rau qhov txaus ntshai zais ntawm qhov xwm txheej tsaus ntuj loj thiab lawv cov kev ntsuas tiv thaiv.
