Txoj haujlwm kawg ntawm kev tsim kho ntawm Central Tuam Tshoj UHV AC "hnub"-zoo li ob lub nplhaib network - 1000 kV Wuhan-Nanchang UHV AC qhov project, nruab nrog cov hloov pauv siab heev, disconnectors, xob laim ntes thiab lub tshuab nqus tsev vacuum, tam sim no tau pib sim. kev ua haujlwm. Tom qab 7 xyoo ntawm kev npaj thiab kev tsim kho, raws li kev coj noj coj ua ntawm State Grid Corporation ntawm Tuam Tshoj, kev tsim kho ntawm Central China UHV AC "sun"-shaped ob-ntiv nplhaib network tau ua tiav tiav. Central China Power Grid tau tsim tag nrho cov kab hluav taws xob zoo li lub zog nrog UHV thiab EHV raws li lub pob txha caj qaum, nrog rau cov khoom siv tseem ceeb xws li cov fuses tawm thiab cov transformers loj.
Central Tuam Tshoj UHV AC "lub hnub"-zoo li ob-ntiv nplhaib network tau tshiab tso rau hauv kev ua haujlwm 1000 kV "5 chaw nres tsheb, 10 transformers (nrog rau ntau yam transformers loj), 15 kab", nrog rau tag nrho cov transformer muaj peev xwm ntawm 30 lab kVA thiab tag nrho. kab ntev li ntawm 3,955 km. Lub Tuam Txhab Tuam Txhab Hluav Taws Xob tau tsim los ntawm daim phiaj hluav taws xob radial nrog 500 kV daim phiaj hluav taws xob raws li lub nraub qaum thiab Hubei ua qhov chaw nruab nrab rau cov kab hluav taws xob sib txuas nrog 1000 kV thiab 500 kV fais fab tuag raws li lub nraub qaum thiab ntau lub xeev interconnected. Cov nodes tseem ceeb yog nruab nrog kev ua haujlwm siab disconnectors thiab lub tshuab nqus tsev vacuum breakers. AC daim phiaj nqa peev xwm tau txhim kho, qhov "muaj zog DC thiab tsis muaj zog AC" teeb meem tau txo qis, kev sib txuas hluav taws xob hauv lub xeev tau los ze zog, cov yam ntxwv ntawm kev sib koom ua ke hauv cheeb tsam tau dhau los ua qhov tseem ceeb, thiab cov yam ntxwv ntawm kab sib chaws ruaj khov tau dhau los. kev txhim kho zoo, ua tiav "peb qhov kev hloov kho tshiab thiab peb qhov kev txhawb nqa"
Lub peev xwm faib peev txheej tau dhau los, thiab lub peev xwm ntawm Central Tuam Tshoj UHV DC kis tau tus mob tau nce mus rau 6 lab kilowatts, nrog kev nce ntxiv ntawm 6.9 lab kilowatts. Lub peev xwm kis tau tus mob ntawm cov channel tseem ceeb ntawm thiab hauv lub xeev tau nce los ntawm 21 lab kilowatts. Cov kab no tau nruab nrog qhov tsim nyog tso tawm fuses kom muaj kev nyab xeeb, muab kev txhawb nqa rau kev hloov hluav taws xob sab nraud hauv cheeb tsam thiab kev sib pauv hloov hluav taws xob hauv cheeb tsam; Lub peev xwm txais hluav taws xob ntawm plaub lub xeev hauv Central Tuam Tshoj tau txhim kho zoo heev, thiab lub zog siab tshaj plaws tau txais lub peev xwm ntawm cov phiaj xwm hluav taws xob hauv Hubei, Hunan, Henan thiab Jiangxi tau nce los ntawm 5 lab, 6 lab, 3.7 lab thiab 5 lab kilowatts feem. , thiab qhov kev tso tawm ntawm qhov ruaj khov rotating cia ntawm tag nrho cov network tau tshaj 9 lab kilowatts, uas tau muab kev txhawb nqa rau kev nyab xeeb ntawm Central Tuam Tshoj lub zog hluav taws xob hauv qab qhov xwm txheej tshiab. Cov txheej txheem no yog sib cais los ntawm kev ua haujlwm zoo ntawm cov khoom siv hloov pauv thiab cov khoom siv hluav taws xob hauv txhua lub chaw ua haujlwm substation; Kev ua haujlwm yooj yim ntawm daim phiaj hluav taws xob tau zoo dua qub, thiab qhov tsawg kawg ntawm kev pib ua haujlwm ntawm Central Tuam Tshoj lub zog hluav taws xob tau raug txo los ntawm ntau dua 20 units, nrog rau lub peev xwm ntawm 10 lab kilowatts, uas muab kev txhawb nqa rau kev hloov pauv ntawm txoj kev pib. rau tag nrho lub network, kev tswj hwm kev thauj khoom nruab nrab ntawm lub xeev, thiab kev siv hluav taws xob loj loj. Tag nrho cov no yog vim kev ua kom zoo ntawm cov qauv hluav taws xob hluav taws xob thiab kev siv dav dav ntawm cov cuab yeej siv qib siab xws li lub tshuab nqus tsev vacuum.
Lub rau lub phiaj xwm uas tsim "hnub"-zoo li ob lub nplhaib sib txuas ntawm Central China UHV AC tau raug suav nrog hauv lub tebchaws. Raws li lub koom haum sib koom ua ke ntawm lub tuam txhab, Central Tuam Tshoj ceg ntawm Lub Xeev Grid tau ua tus thawj coj hauv kev daws teeb meem kev tshawb fawb thiab ua nws txoj haujlwm nrog plaub lub tuam txhab hluav taws xob hauv xeev, Lub Xeev Grid Economic Research Institute, Tuam Tshoj Hluav Taws Xob Tshawb Fawb Lub Tsev Haujlwm thiab lwm yam. Rau lub koom haum tsim hluav taws xob hauv cheeb tsam suav nrog Central South, East China, Southwest, Northwest, Northeast Tuam Tshoj thiab Tuam Tshoj National Nuclear Corporation thiab 14 lub koom haum tsim hluav taws xob hauv xeev suav nrog Hubei, Hunan thiab Henan koom ua haujlwm tsim tshwj xeeb. Kev tsim kho ntawm Central Tuam Tshoj UHV AC "hnub" zoo li lub nplhaib ob lub nplhaib sib txuas pib thaum Lub Peb Hlis 2019. Txhua chav tau txhawb nqa tag nrho kev sib koom tes thiab kev tswj hwm kev tsim kho, thiab ua tiav cov txiaj ntsig tseem ceeb xws li pib tsim thiab commissioning ntawm Nanchang-Changsha UHV AC project hauv tib lub xyoo. Cov khoom siv hluav taws xob tseem ceeb tau hais los saum toj no tau muab tso ua ke hauv cov haujlwm no.
