Tsim kom muaj ib lub laj kab ntse tseem nyob ze
Cov ntse hauv lub neej yav tom ntej yog "Internet Internet" nrog cov phiaj xwm muaj zog, dav sib txuas, kev txawj ntse thiab qhib kev sib txuas lus. UHV yog lub hauv paus ntawm lub ntse ntse network thiab lub ntsiab feem ntawm kev siv hluav taws xob hauv Internet.
Lub Tsib Hlis 6, Yu Xinqiang, tus pab tus thawj coj ntawm State Grid Corporation, tau hais nyob hauv kev xam phaj: "Tsim UHV yog qhov tsis muaj txiaj ntsig ntawm tsoomfwv kev ruaj ntseg, kev ua kom muaj zog, kev tsim kho lub dag zog, kev tsim kho kev tsim kho kev lag luam, tshwj xeeb tshaj yog daws cov teeb meem smog xaiv. "
Nws to taub hais tias qhov teeb meem ntawm smog nyob rau hauv thaj chaw nruab nrab ntawm sab hnub tuaj thiab hauv cheeb tsam ntawm Tuam Tshoj yog ib qho tseem ceeb, thiab qhov loj ntawm qhov nruab nrab ntawm kev siv hluav taws xob yog qhov tseem ceeb. Cov hluav taws kub muaj peev xwm ntawm lub peev xwm ntawm Beijing-Tianjin-Hebei thiab Yangtze River Delta regions, uas muaj teeb meem loj, tshaj 130 lab kilowatts thiab 140 lab kilowatts feem. Qhov muaj peev xwm ntawm cov hluav taws xob tau siv hluav taws xob ib cheeb tsam yog 13 zaug thiab 26 npaug ntawm thaj av qaum teb, raws li. Ntau tshaj tsib zaug hauv teb chaws nruab nrab.
Txheeb xyuas kev qhia tias leej fajxim dioxide, nitrogen oxides thiab soot emissions ntawm tus nqi hluav taws xob tawg yog 86%, 56% thiab 74% ntawm lub teb chaws tag nrho. 50% mus rau 60% ntawm PM2.5 yog muab los ntawm thee combustion. Ntawm lawv, cov phev dioxide emissions ntawm cov hluav taws xob ncaj qha hluav taws xob yog sib npaug rau ntawm cov hluav taws xob, thiab qhov nyiaj ntawm soot emissions yog nyob ze rau peb lub sij hawm ntawm thee, uas yog lub ntsiab qhov ntawm huab cua pa phem. Txawm hais tias kev siv hluav taws xob ua kom muaj hluav taws xob muaj zog ntau dua thiab tsis muaj paug ntau dua li cov khib nyiab khib nyiab, nws yog nyob nruab nrab ntawm cov cheeb tsam sab nruab nrab thiab nruab nrab vim kev siv tag nrho cov hluav taws xob ntau, thiab yog ib qho tseem ceeb ntawm huab cua pa phem.
Yu Xinqiang ntseeg hais tias qhov kev loj hlob ntawm UHV fais fab grids, hloov hliv xa hluav taws xob kis mus rau, thiab nce qhov kev faib ua feem ntawm lwm lub hwj chim tau txais, muaj peev xwm ho txhim kho cov kev mob atmospheric hauv thaj chaw nruab nrab thiab hauv paus.
Raws li lub Xeev Grid Corporation txoj kev npaj, los ntawm 2015, 2017, thiab 2020, lub trans-regional kislas muaj peev xwm yuav ncav cuag 210 million kilowatts, 290 lab kilowatts, thiab 450 lab kilowatts, thiab qhov hluav taws xob xa mus rau cov cheeb tsam sab hnub tuaj thiab sab nruab nrab yuav ncav cuag 0.74 trillion kilowatts thiab 1.18, feem. Trillion kWh, 1.87 trillion kWh. Raws li qhov no xam ntawm hluav taws xob noj, nws muaj peev xwm ua kom txo tau cov cua ntawm thermal thee nyob rau hauv central thiab central regions los ntawm 340 lab tons, 540 lab tons thiab 850 lab tons, thaum lub PM2.5 emissions nyob rau hauv sab hnub tuaj thiab nruab nrab central yuav ua tau txo 9.4%, 15.8% thiab 22.6% muab piv rau 2010. Nws tuaj yeem pom tau tias kev ceev cov UHV tuaj yeem daws qhov teeb meem loj ntawm smog nyob rau hauv cov cheeb tsam nruab nrab thiab sab nruab nrab ntawm qhov chaw. Hauv no hais txog, Yu Xinqiang npaj siab koom nrog UHV qhov kev tsim tawm hauv txoj kev npaj ua kom tiav ntawm Lub Tebchaws Them Nqi Tiv Thaiv Kev Tiv Thaiv Cov Hwjchim.
Ntau tshaj li 70% ntawm Tuam Tshoj lub tshuab hluav taws xob, hluav taws xob, cua thiab hnub ci zog yog cov concentrated nyob rau sab hnub poob thiab sab qaum teb, thaum lub zog thauj cov chaw zov me nyuam raug muab faib rau cov cheeb tsam sab hnub tuaj thiab sab nruab nrab. Cov sib npaug tsis sib npaug ntawm cov khoom siv hluav taws xob thiab cov khoom tsim tau ua rau nyuaj rau Suav teb kom ruaj khov rau cov khoom siv hluav taws xob kom tau raws li qhov xav tau ntawm thaj chaw nruab nrab ntawm sab hnub tuaj thiab hauv paus.
Yuav kom tswj tau nrog Tuam Tshoj txoj kev loj hlob muaj zog, los daws qhov tsis txaus siab nyob rau hauv thaj tsam ntawm kev siv hluav taws xob thiab kev thov hluav taws xob, kom ua tau raws li cov khoom qis qis qis rau kev sib raug zoo thiab kev lag luam rau lub zog fais fab, nws yog ib qho tseem ceeb heev kom ceev kev loj hlob ntawm ntse grids. Vim li ntawd, Lub Xeev Grid Corporation tau tso tawm "Txoj Kev Ntsuas Qib Smart" txoj kev npaj tsim tau hauv lub Tsib Hlis 2009.
Raws li daim ntawv tshaj tawm, raws li txoj kev npaj, txoj kev loj hlob ntawm "Strong Smart Grid" muab faib ua peb theem: 2009-2010 yog kev npaj theem pib, npaj ntsees rau kev tsim muaj cov qauv ntse tsim ntsej muag cov qauv kev tswj thiab tswj cov kev cai, qhov tseem ceeb technology tshawb nrhiav thiab kev loj hlob thiab kev tsim khoom. Thiab kev ua haujlwm hauv txhua txoj haujlwm; 2011-2015 yog ib txoj kev tsim kho, ua kom txoj haujlwm ntawm UHV fais fab grids thiab tes hauj lwm hauv nroog thiab cov nroog; thiab tsim kom muaj kev sib haum xeeb "muaj zog ntse hauv daim phiaj" ntawm xyoo 2016 mus txog 2020.
Thaum lub Xya Hli Ntuj 2013, lub Rooj Sib Tham Thaj Tsam Xeev tau teev tseg "qhov kev tsim kho cov lag luam hauv nroog loj thiab txhawb kev txawj ntse ntawm lub hwj chim" raws li kev ua haujlwm ntawm kev tshawb nrhiav thiab kev tsim kho thiab kev tsim kho kev lag luam hauv nroog.
Lub Xeev Grid Corporation tau hais tias thaum lub sijhawm "Twelve Five Five Year Plan", nws yuav ua lag luam 500 billion yuan los tsim kom muaj ib qho "peb kab rov tav thiab peb vertical" txauv UHV pob txha kab sib chaws thiab 13 ntev-ntev DC txoj haujlwm txuas ntxiv rau cov kev ua kom muaj zog loj thiab thauj cov chaw zov me nyuam. Ua ib lub ntiaj teb-qib "muaj zog ntse hauv daim phiaj." Tsis tas li ntawd, txoj kev loj hlob ntawm Teb Chaws Asmeskas Hwj Huam Lub Zos tau npaj siab tias qhov kev tsim kho cov ntse ntse yuav nce siab, thiab los ntawm 2020, qhov kev pab cuam automation ntawm cov tuam txhab hauv nroog yuav ncav cuag 80%.
Kev txhawb nqa cov cai tswjfwm heev tau tsav lub lag luam ntse ntse mus txuas ntxiv kom sov dua. Nws to taub tias cov peev hauv lub teb chaws yuav tuaj txog 3 trillion yuan nyob rau hauv lub 8 xyoo tom ntej, uas tus UHV grid yuav nyob 950 billion yuan. Lub lag luam loj loj txhais tau hais tias qhov kev txiav txim siab ntawm kev loj hlob mus txuas ntxiv ntawm kev ntse hauv daim phiaj yog qhov muaj zog heev, muaj nqis tshaj qhov lag luam nruab nrab. "Tus nqi ua lag luam coj los ntawm qhov ntse hauv daim phiaj yog tsis muaj tsawg tshaj li qhov nthwv dej ntawm kev tshaj tawm," cov kws ua lag luam said.
UHV yuav tshem tawm cov pa phem nyob hauv Suav teb
Vim tias lub zog ntawm lub zog nyob hauv lub nroog mus ntev, Tuam Tshoj lub zog qis tshaj yog nyob ntawm kev siv tsheb thauj mus los, cov feem sib npaug ntawm kev sib kis tsawg, tus qauv yog tsis muaj qhov sib npaug, thiab cov khoom siv hluav taws xob muaj zog heev.
Kev txheeb xyuas qhia tau tias nyob rau xyoo 2013, ntau dua 50% ntawm kev siv hluav taws xob tau siv, 58% ntawm txoj kev tsheb ciav hlau siv hluav taws xob thauj, thiab 70 feem pua ntawm cov tsheb raug thauj los ntawm kev tsheb ciav hlau. Qhov faib ntawm cov tsheb thauj mus los thiab kis mus rau qhov chaw Huadong Coal yog pauv li ntawm 48: 1, thiab qhov feem pua ntawm cov tsheb thauj mus los ntawm cov hluav taws kub tawm ntawm "Sanxi" (Shanxi, Shaanxi, Mengxi) yog li 15: 1. Nws tuaj yeem pom tias qhov teeb meem ntawm ceev hluav taws xob thiab cov tsheb thauj mus los ntawm lub hauv paus ntawm lub zog ntawm lub zog yog qhov tseem ceeb heev.
Yuav kom daws tau cov teebmeem no, raws li Yu Xinqiang, lub ntsiab lus tseem ceeb ntawm kev hloov cov kev hloov ntawm kev siv hluav taws xob uas siv ntau tshaj ntawm cov tsheb npav thauj mus los thiab ib feem ntawm txoj kev loj hlob ntawm txoj kev loj hlob, uas yog siv "ib qhov tshwj xeeb plaub" , thiab tsim lub UHV ua tus ntaus pob txha. Lub tuam tsev ib lub zog ntse ntse los ntawm lub hwj chim sib npaug ntawm txhua theem, tsim hluav taws xob loj, hluav taws xob, lub zog hluav taws xob thiab txuas ntxiv zog rau hauv paus, "ua tiav ntawm cov cua ntawm hluav taws xob thiab xa hluav taws xob mus rau Xov Xwm" ntawm cov khoom siv hluav taws xob thoob teb chaws. Kev siv tau zoo tau txo qhov ntom ntim ntawm cov hluav taws xob thiab hluav taws xob hauv cheeb tsam nruab nrab thiab sab nruab nrab. "
Nws to taub hais tias cov hauj lwm rau txoj kev loj hlob ntawm UHV fais fab hauv Suav nyob hauv Cheeb Tsam lawm. Nyob rau hauv xyoo tsis ntev los, nws tau ua tsib ultra-siab voltage AC thiab DC tej yaam num nrog lub siab tshaj plaws, qhov muaj peev xwm thiab kev siv technology hauv ntiaj teb. Nws tau xyuam xim ua hauj lwm thiab tshawb xyuas qhov kev nyab xeeb, kev lag luam thiab kev phooj ywg ntawm UHV. Pw ua ke. "Thaum lub caij ntuj sov lub caij ntuj sov, qhov chaw ntau qhov chaw tau ntaus cov ntaub ntawv siab, thiab UHV loj zog cov phiaj xwm tau ua lub luag haujlwm zoo tshaj plaws rau qhov kev faib khoom ntawm cov chaw muab kev pab cuam, kom tsis muaj teeb meem ntawm qhov kev thov thiab kev thov." Yu Xinqiang said.
Nyob rau tib lub sijhawm, UHV yeej tau txais ntau lub tebchaws. Suav teb tau ua tiav cov cuab yeej cuab tam UHV thiab ua tiav cov cuab yeej tsim kev lag luam, thiab tau "Tuam Tshoj txoj kev tsim" thiab "Tuam Tshoj txoj hau kev".
Raws li lub tswv yim ntawm Lub Xeev Grid Corporation, los ntawm 2020, nws yuav tsim ib qho qauv qiv rau kev sib txuas nrog ntau lub zog loj zog thiab cov chaw loj thauj neeg, loj "West-to-East Power Transmission" thiab "Nortel Power Transmission South China ", nrog lub trans-regional kis tau tus mob 450 lab kilowatts. Tshuav 550 laab kilowatts ntawm lub zog huv si tau xa tawm thiab consumed.
Lub sij hawm ntawd, lub zog hluav taws xob nyob rau sab hnub tuaj thiab sab nruab nrab thaj tsam yuav ncav cuag 350 lab kilowatts, thiab txhua xyoo muaj tshaj li 1.9 trillion kilowatt xuab moos. Lub zog ntws mus rau thaj chaw yog 2.69 npaug thiab 2.5 npaug ntawm cov hluav taws xob uas muaj hluav taws xob nyob hauv Beijing-Tianjin-Hebei thiab Yangtze River Delta regions, uas yog huab cua loj heev nyob rau hauv nruab nrab thiab sab hnub tuaj.
Obviously, nyob rau hauv ntev khiav, txoj kev loj hlob ntawm UHV yuav fundamentally pab alleviate qhov teeb meem ntawm huab cua pa phem nyob rau hauv Suav teb.
