Daim ntawv thov ntawm UHV fais fab kis thiab hloov tshuab los tsim UHV network tuaj yeem txhim kho kev nyab xeeb, kev ntseeg tau thiab kev lag luam ntawm daim phiaj hluav taws xob; daim ntawv thov ntawm UHV fais fab kis thiab hloov tshuab tuaj yeem daws qhov teeb meem ntawm lub zog network kev ruaj ntseg los ntawm kev tsis muaj zog hla cheeb tsam kev sib txuas ntawm daim phiaj hluav taws xob, thiab muab lub zog hluav taws xob muaj zog rau kev tsim khoom thiab kev tsim kho nyob rau sab hnub tuaj Suav teb; daim ntawv thov ntawm UHV fais fab kis thiab hloov tshuab tuaj yeem daws qhov teeb meem ntawm luv-circuit tam sim no tshaj qhov txwv ntawm daim phiaj hluav taws xob hauv cov cheeb tsam siab, txo cov xov tooj ntawm txoj hauv kev loops thiab txuag av. Kev suav thiab cov ntawv siv tau ua pov thawj tias ± 800 kV DC kis tau tus mob yog tsawg dua li ± 600 kV DC kis kab mob, uas tuaj yeem txuag tau qhov kis tau tus mob ntawm thaj tsam ntawm 300 k㎡. Thaum kis tau tus mob 100 000 kW ntawm lub zog hluav taws xob thiab qhov kev ncua deb yog 800 km, nws yuav siv sij hawm 8 mus rau 10 zaus siv 500 kV AC kab, thaum nws tsuas siv 2 zaug los siv UHV kis tau tus mob network, uas tuaj yeem ua rau luv luv. kis tau tus mob channel dav los ntawm 0.3 km thiab txuag lub kis tau tus mob channel cheeb tsam ntawm 240 k㎡, uas muaj cuab kev zoo economic zoo.
Daim ntawv thov ntawm UHV fais fab kis tau tus mob thiab hloov tshuab thiab UHV daim phiaj hluav taws xob tuaj yeem pab tsim kom muaj kev sib txuas loj thoob plaws hauv cheeb tsam, paub txog qhov siab tshaj plaws staggering, ncov shaving, dej thiab hluav taws reciprocity, thiab txo cov hluav taws xob poob; Daim ntawv thov ntawm UHV fais fab kis tau tus mob thiab kev siv tshuab hloov pauv tuaj yeem txo qhov siab ntawm kev thauj mus los ntawm cov thee thiab txhawb kev siv cov thee hnyav. Tam sim no, muaj qee yam kev tsis sib haum xeeb hauv kuv lub teb chaws kev faib hluav taws xob. Lub zog siv hluav taws xob nyob rau hauv nruab nrab thiab sab hnub poob cheeb tsam kuj muaj ntau, thiab kev siv hluav taws xob nyob rau sab hnub tuaj ntug dej hiav txwv yog qhov loj, thiab muaj teeb meem tsis txaus lub zog. Daim ntawv thov ntawm UHV fais fab kis thiab hloov tshuab yuav pab rau sab hnub poob-sab hnub tuaj xa hluav taws xob, uas tuaj yeem ua rau thaj tsam sab hnub poob muab kev ua si tag nrho rau nws cov peev txheej zoo, txo lub zog siab hauv nruab nrab thiab sab hnub tuaj, thiab txhawb kev sib koom tes. ntawm lub regional kev lag luam thiab zej zog.
Hauv kev tshawb fawb ntawm UHV fais fab kis thiab hloov tshuab tshuab, Tuam Tshoj tau ua tiav kev txhim kho ntawm lub ntiaj teb loj tshaj plaws AC fais fab kis tau tus mob thiab hloov qhov project thaum lub sij hawm "Twelfth Five-Year Plan" lub sijhawm. Qhov kev tshwm sim ntawm qhov project no tsis tsuas yog daws cov teeb meem kev teeb meem hauv kev npaj thiab kev ua haujlwm ntawm lub zog hluav taws xob, tab sis kuj ua kom lub sijhawm ruaj khov ntawm lub zog hluav taws xob siab. Tsis tas li ntawd, UHV system muaj kev sib raug zoo nrog lub network sib txuas, thiab kev tshawb fawb ntawm UHVDC kis tau tus mob thev naus laus zis tuaj yeem tsim cov xwm txheej zoo rau kev ua haujlwm nyab xeeb ntawm lub zog hluav taws xob, txhim kho qib kev pab cuam thaum muaj xwm txheej ceev ntawm lub zog hluav taws xob, thiab txhim kho quotas.
