Gutezimbere tekinike ya UHV AC yohereza no guhindura ibikoresho

Igikoresho cyindishyi za UHV

Kubwubatsi bunini bwubaka ultra-high voltage imishinga, ibikoresho byingenzi nurufunguzo.

Mu rwego rwo guteza imbere iterambere ry’ikoranabuhanga rya UHV AC, iterambere rya tekiniki rigezweho ryibikoresho byingenzi

nka transformateur ya UHV AC, gaze yometse kuri gaze ifunze switchgear (GIS), ibikoresho byindishyi zikurikirana hamwe nabafata inkuba ni

incamake kandi iteganijwe.

Ibisubizo byerekana ko:

Agaciro kemewe kumashanyarazi yumuriro mugihe igice cyo gusohora igice cya UHV transformateur ari 1 ‰ bizatoranywa nku

imbaraga zemewe zumurima;

Ingamba zo kugenzura ibintu bya magneti nko gukingira magnetique kumpera yumubiri, gukingira amashanyarazi ikigega cyamavuta, gukingira magneti

ya tank ya peteroli, hamwe na plaque idafite ibyuma ikora ibyuma birashobora kugabanya neza imbaraga za magneti no kuzamuka kwubushyuhe bwa MVA 1500

ubushobozi bunini bwa UHV transformateur;

Ubushobozi bwo kumena amashanyarazi ya UHV burashobora kugera kuri 63kA.Ikizamini cya sintetike cyizamini gishingiye kuri "uburyo butatu bwumuzunguruko" burashobora gucika

unyuze kumupaka wibikoresho byo kwipimisha no kurangiza ikizamini cyo kumena 1100kV yamashanyarazi;

Biragaragara ko amplitude hamwe na frequence ya VFTO bigarukira mugushiraho rezistor de damping kuruhande ruhagaze rwa "vertical"

guhagarika;

Urebye kubijyanye na voltage ikora ikomeza, ni byiza kugabanya voltage yagenwe ya UHV ifata kuri 780kV.

Ibihe bizaza UHV AC yohereza no guhindura ibikoresho bigomba kwigwa cyane mubijyanye no kwizerwa cyane, ubushobozi bunini,

ihame rishya ryakazi hamwe nibikorwa byo gukora neza.

UHV AC transformateur, switchgear, ibikoresho byindishyi zuruhererekane hamwe nabafata inkuba nibikoresho byingenzi byingenzi byohereza UHV AC

umushinga.Iki gihe, tuzibanda ku gutondeka no kuvuga muri make iterambere rigezweho ryikoranabuhanga ryubwoko bune bwibikoresho.

Gutezimbere ibikoresho bya UHV byindishyi

Igikoresho cy'indishyi za UHV gikemura cyane cyane ibibazo bikurikira: ingaruka zo gusaba indishyi zikurikirana kuri

sisitemu iranga, gutezimbere ibyingenzi byingenzi bya tekiniki yuruhererekane rwindishyi, imbaraga zikomeye zo kurwanya amashanyarazi

ubushobozi bwo kwivanga muri sisitemu yo kugenzura, kurinda no gupima, gushushanya no kurinda banki ya super capacitor ,.

ubushobozi bwo gutembera no gukora kwizerwa ryurukurikirane rwindishyi zitera icyuho, ubushobozi bwo kurekura igitutu nibikorwa byo kugabana ubu

ya voltage limiter, gufungura byihuse no gufunga ubushobozi bwa bypass, igikoresho cyo kumanika, inkingi ya fibre Imiterere

igishushanyo mbonera cya transformateur nibindi bibazo byingenzi bya tekiniki.Mubihe bya ultra-high voltage, ultra-high current and ultra-high

ubushobozi, ikibazo cyuko umubare munini wibipimo bya tekinike byerekana urukurikirane rwibikoresho byingenzi bigera kumipaka

yaratsinzwe, kandi ultra-high voltage series indishyi ibikoresho byibanze byatejwe imbere, kandi byose byagezweho

Ahantu.

Banki

Banki ya capacitori yindishyi zikurikirana nigice cyibanze cyumubiri kugirango tumenye ibikorwa byindishyi zuruhererekane, kandi nikimwe mubyingenzi

ibikoresho by'uruhererekane rw'ibikoresho by'indishyi.Umubare wa UHV urukurikirane rwindishyi murwego rumwe rugera kuri 2500, inshuro 3-4

iy'indishyi za 500kV.Irahura numubare munini wuruhererekane rwibibazo bihuza ibibazo bya capacitori munsi nini

ubushobozi bw'indishyi.Gahunda yo gukingira H-ikiraro kabiri irasabwa mubushinwa.Hamwe na tekinoroji nziza yo gukoresha, irakemura

ikibazo cyo guhuza hagati yubukangurambaga bwimiterere idahwitse ya capacator hamwe no kugenzura ingufu zatewe, kandi nanone

ikemura ikibazo cya tekiniki gishoboka guturika kwa seriveri ya capacitori.Igishushanyo cyibintu hamwe nigishushanyo mbonera cyibishushanyo mbonera

amabanki yerekanwa mu gishushanyo cya 12 n'icya 13.

Igishushanyo cya 12 Ububiko bwa banki

Igishushanyo cya 13 Uburyo bwo gukoresha

Umuvuduko ukabije

Urebye ibyifuzo byingirakamaro cyane byingirakamaro byindishyi za UHV, uburyo bwo guhuza chip irwanya ni umwihariko

gutezimbere, hamwe na coefficient ya shunt hagati yinkingi yagabanutse kuva kuri 1.10 igera kuri 1.03 nyuma yinkingi 100 zirwanya chip inkingi ya buri cyiciro

voltage limiter ihujwe murwego rumwe (buri ristoriste chip inkingi ihujwe murukurikirane na 30 résistoriste).Umuvuduko wateguwe

imiterere yo kurekura iremewe, kandi ubushobozi bwo kurekura igitutu bugera kuri 63kA / 0.2s hashingiwe ko igitutu cya farashi

igice cya limiter gifite uburebure bwa 2,2m kandi nta arc itandukanya imbere.

Ikinyuranyo

Umuvuduko wapimwe wicyuho cya spark kumurongo wa UHV indishyi zigera kuri 120kV, zikaba zisumba cyane 80kV yikinyuranyo cya UHV

indishyi zikurikirana;Ubushobozi bwo gutwara ubu bugera kuri 63kA / 0.5s (agaciro kangana na 170kA), inshuro 2,5 zubusa bwa ultra-high voltage icyuho.Uwiteka

icyuho cya spark icyuho gifite imikorere nkukuri, igenzurwa kandi ihamye ya trigger isohora voltage, amakosa ahagije atwara

ubushobozi (63kA, 0.5)

ubungubu, kugarura voltage kugiciro cyagaciro kigera kuri 2.17 mugihe cya 650m), imbaraga zikomeye zo kurwanya amashanyarazi, nibindi.

Urubuga rwindishyi

Urwego ruciriritse, umutwaro uremereye, urwego rwo hejuru rwa seisimike UHV urukurikirane rwindishyi rwateguwe, rukora UHV mpuzamahanga idasanzwe

indishyi zikurikirana ubwoko bwikizamini nubushobozi bwubushakashatsi;Ibice bitatu-byubukanishi nimbaraga zo gusesengura imbaraga za complexe

ibikoresho byinshi byashizweho, hamwe nuburyo bworoshye hamwe na gahunda yo gushyigikira ibice bitatu byubwoko bwa bisi ya platform hamwe nibikoresho

harasabwa kandi imiterere nini yo kuzitira, ikemura ibibazo byo kurwanya imitingito, guhuza ibikorwa ndetse n’ibidukikije bya electromagnetic

kugenzura urubuga ruremereye (200t);Urwego rwa UHV indishyi zubwoko bwukuri bwikizamini rwubatswe, rukora urwego runini

guhuza ibikorwa byo hanze, guhuza corona hamwe numwanya wumurima imbaraga, electromagnetic ihuza ibikoresho bidafite imbaraga bigezweho kurubuga

nubundi bushobozi bwibizamini byuruhererekane rwindishyi, kuzuza ubusa bwubushakashatsi bwikizamini cya UHV.

Hindura byypass na bypass disconnector

Ubushobozi bunini arc kuzimya icyumba hamwe nuburyo bwihuse bwo gukora bwateguwe, byakemuye ibibazo byubuyobozi

nimbaraga za mashini ya 10m ultra ndende ikinguye gukurura inkoni munsi yihuta.Ubwoko bwa mbere bwa SF6 ya farashi yinkingi yubwoko bwa bypass

hamwe na T-imiterere yubatswe yatejwe imbere, hamwe numuvuduko wa 6300A, igihe cyo gufunga m 30m, nubuzima bwa mashini inshuro 10000;

Uburyo bwo kongeramo vacuum yamashanyarazi kumashanyarazi nyamukuru no guhinduranya amashanyarazi na pole nkuru birasabwa.Iya mbere

fungura ubwoko bwa bypass disconnector yatejwe imbere, kandi ubushobozi bwo guhinduranya ibintu byahinduwe cyane kugeza 7kV / 6300A.

Electromagnetic ihuza ibikoresho bidakomeye bigezweho kurubuga

Ibibazo bya tekiniki nko kugenzura birenze urugero kuri UHV ikurikirana ryindishyi hamwe na electromagnetic ihuza

ibikoresho bigezweho bigezweho kandi birashoboka cyane byatsinzwe, hamwe nurwego rwindishyi

sisitemu yo gupima hamwe na spark icyuho gikurura agasanduku hamwe nubushobozi bukomeye bwo kurwanya electromagnetic ubushobozi bwo kwivanga bwabaye

yateye imbere.Igicapo 14 nigishushanyo mbonera cyibikoresho byindishyi za UHV.

Mpuzamahanga ya mbere ya UHV igizwe nuruhererekane rwindishyi zikoreshwa mu bwigenge n’ikigo cy’ubushakashatsi cy’amashanyarazi mu Bushinwa

yashyizwe mubikorwa mumushinga wo kwagura umushinga wa UHV AC.Ikigereranyo cyagenwe cyibikoresho

igera kuri 5080A, kandi ubushobozi bwapimwe bugera kuri 1500MVA (imbaraga zidasanzwe).Ibipimo byingenzi bya tekiniki biza ku mwanya wa mbere kwisi.Uwiteka

ubushobozi bwo kohereza umushinga wa UHV werekana ibizamini byiyongereyeho miliyoni imwe.Intego yo kohereza neza 5

miliyoni kWt kumurongo umwe UHV imirongo yagezweho.Kugeza ubu, ibikorwa bifite umutekano, bihamye kandi byizewe byarakomeje.
