Tsis ntev los no, nws tau kawm los ntawm Northwest Branch of State Grid Corporation ntawm Tuam Tshoj tias txij Lub Xya Hli mus txog Lub Yim Hli xyoo no, tag nrho ntawm 523 lab kWh ntawm hluav taws xob tau pauv nyob rau hauv nruab nrab- thiab mus sij hawm ntev kev sib txuas hauv nroog los ntawm Gansu, Qinghai. , Ningxia mus rau Anhui, thiab lwm yam, thiab tag nrho lawv tau ua tiav los ntawm kev ua tib zoo tsim hluav taws xob xa mus rau txoj hauv kev, suav nrog Qingyu DC thiab Peb Gorges Hydropower Channel (Yihua, Linfeng, Genan, Longzheng DC), thiab kev tswj xyuas meej ntawm cov khoom siv hloov, kom ua tiav qhov ruaj khov. kev xa hluav taws xob hluav taws xob. Nyob rau hauv cov txheej txheem no, tus disconnector xyuas kom muaj kev nyab xeeb kev sib cais thiab kev saib xyuas ntawm daim phiaj hluav taws xob thaum tsim nyog, thiab lub teeb ntes hluav taws xob tiv thaiv kev hem thawj ntawm kev puas tsuaj ntuj xws li xob laim rau cov khoom siv sib kis.
Txhawm rau txuas ntxiv nthuav dav qhov ntsuas thiab kev ua tau zoo ntawm "West-to-East Power Transmission", Northwest Branch of State Grid insists on multi-tog kev sib koom tes thiab kev koom tes. Nyob rau theem pib, nws tau mus rau Lub Xeev Grid Central Tuam Txhab Tuam Txhab, Lub Xeev Grid Henan Power thiab lwm yam kev tshawb nrhiav ntawm qhov chaw ntawm kev siv cov kab hla hauv nroog thiab hla cheeb tsam, nkag siab tob txog cov xwm txheej cuam tshuam rau kev sib kis, thiab teeb tsa lub tshuab nqus tsev. Circuit Court breakers los txhim kho cov lus teb ceev ceev thiab kev sib cais muaj peev xwm ntawm daim phiaj hluav taws xob. Nyob rau tib lub sijhawm, ua ke nrog cov tuam txhab lag luam ntawm tsib lub xeev qaum teb sab hnub poob (cov cheeb tsam tswj hwm tus kheej), lawv tau soj ntsuam qhov kev nce qib ntawm cov phiaj xwm kev lag luam hauv lub xeev, tshawb xyuas qhov muaj peev xwm kis tau tus kab mob hla hauv cheeb tsam thiab hla lub xeev, thiab paub txog cov khoom lag luam. Kev hloov pauv hloov pauv tau yooj yim thiab kev sib kis tau zoo ntawm qib voltage, tshwj xeeb tshaj yog nyob rau hauv qhov kev ua kom zoo ntawm cov transformers.
Lub Tuam Txhab Northwest ntawm Lub Xeev Grid kuj tau koom tes nrog kev lag luam thiab xa tawm cov tuam haujlwm ntawm ntau lub xeev (cov cheeb tsam tswj hwm tus kheej) txhawm rau taug qab cov kev tsim tawm tshiab ntawm lub zog tshiab hauv cheeb tsam, kev hloov pauv hauv dej ntws thiab lub zog thauj khoom hauv cov dej phwj tuaj, thiab ua kom muaj kev nyab xeeb. kev ua haujlwm ntawm daim phiaj hluav taws xob nyob rau hauv cov xwm txheej txawv txav los ntawm kev tiv thaiv ceev ceev ntawm lub fuse fuse. Lawv tau nce kev sib kis ntawm cov khoom siv hluav taws xob tshiab thiab cov dej siv hluav taws xob, thiab siv ntau txoj kab sib txuas ua ke fais fab kis tau tus mob kom tsis txhob txhim kho kev siv ntau yam DC kab xws li Qinghai-Henan DC, tab sis kuj tseem txhim kho kev kos npe ntawm tus ntoo khaub lig. -regional nruab nrab- thiab ntev kev lag luam nyob rau sab qaum teb hnub poob.
Txog tam sim no, cov ceg tau siv ntau txoj kab sib txuas ua ke ntawm lub zog sib txuas ua ke los ua 41 kev lag luam, ua tiav tag nrho ntawm 1.6 billion kWh ntawm lub zog xa hluav taws xob, nthuav dav ntau qhov chaw rau kev siv lub zog tshiab hauv Northwest Power Grid. Tsis tas li ntawd, txhawm rau ua kom tau raws li cov kev xav tau ntawm lub zog ntsuab ntawm thaj chaw tau txais, Lub Xeev Grid Northwest Branch innovatively txais ntau yam khoom lag luam xws li kev tsim hluav taws xob hauv lub xeev txoj cai kev lag luam thiab hluav taws xob ntsuab hauv nruab nrab kev sib tw lag luam, thiab txuas ntxiv kom tob rau hluav taws xob. Kev koom tes kev sib raug zoo ntawm cov xeev qaum teb sab hnub poob (cov cheeb tsam tswj hwm tus kheej) thiab cov xeev tau txais, ua tiav cov kev hloov pauv ntawm cov hluav taws xob thermal thiab kev yuav cov hluav taws xob ntsuab, thiab pab cov xeev tau txais txiaj ntsig kom ua tiav qhov kev ntsuam xyuas thiab kev ntsuam xyuas ntawm kev siv hluav taws xob txuas ntxiv dua lub luag haujlwm. thiab lub hom phiaj txuag hluav taws xob.
