Ngo-August 12, I-State Grid Corporation yamemezela ukuthi iphrojekthi ye-Jindongnan - Nanyang - i-Jingmen UHV AC yokuhlola iphumelele isivivinyo sikazwelonke sokwamukela - okusho ukuthi i-UHV ayisekho esigabeni "sokuhlola" kanye "sokubonisa".Igridi yamandla kagesi yaseShayina izongena ngokusemthethweni esikhathini “sogesi ophakeme kakhulu”, futhi ukugunyazwa nokwakhiwa kwamaphrojekthi alandelayo kulindeleke ukuthi kusheshiswe.
Ngokohlelo lokwakhiwa kwephrojekthi ye-UHV evezwe yi-State Grid Corporation ngosuku olufanayo, ngo-2015, kuzokwakhiwa igridi yamandla kagesi ye-UHV "Three Huas" (eNyakatho, eMpumalanga kanye naseCentral China), okwenza "imigqa emithathu eqondile, emithathu enezingqimba futhi inethiwekhi yeringi eyodwa”, kanye namaphrojekthi amanje okudlulisela ngqo e-UHV ayi-11 azoqedwa.Ngokusho kwalolu hlelo, ukutshalwa kwezimali kwe-UHV kuzofinyelela ku-270 billion yuan eminyakeni emihlanu ezayo, kusho abahlaziyi.
Inani lamazinga obuchwepheshe ahamba phambili emhlabeni jikelele
Ngomhla ziyisi-6 kuMasingana, 2009, iphrojekthi yokubonisa i-1000 kV ye-Jindong-Nanyang Jingmen UHV AC yafakwa emsebenzini wokuthengisa.Le phrojekthi izinga likagesi eliphakeme kakhulu emhlabeni, izinga lobuchwepheshe elithuthuke kakhulu kanye nephrojekthi yokudlulisa amandla okuxhumana enamalungelo aphelele azimele empahla yobuhlakani.Kuphinde kube yiphrojekthi yokuqala futhi iphrojekthi yokuqala yokudlulisa amandla kagesi aphezulu kakhulu eyakhiwe yaqala ukusebenza ezweni lethu.
Ngokusho komuntu othintekayo ophethe i-State Grid Corporation, u-90% wezinto zokusebenza zephrojekthi zikhiqizwa ekhaya, okusho ukuthi i-China ikwazi ngokugcwele ubuchwepheshe obuyinhloko bokudluliswa kwe-UHV AC futhi inamandla okukhiqiza ngobuningi bemishini ye-UHV AC. .
Ngaphezu kwalokho, ngalo mkhuba wephrojekthi, i-State Grid Corporation yenze ucwaningo futhi yaphakamisa uhlelo olujwayelekile lobuchwepheshe bokudlulisa i-UHV AC oluhlanganisa amazinga angama-77 ezigabeni eziyi-7 okokuqala ngqa emhlabeni.Kubuyekezwe izinga elilodwa likazwelonke, amazinga kazwelonke ayi-15 kanye namazinga ebhizinisi angama-73 akhishiwe, futhi amalungelo obunikazi angama-431 amukelwe (angu-237 agunyaziwe).I-China isisungule isikhundla esihamba phambili emhlabeni wonke emkhakheni wocwaningo lobuchwepheshe bokudlulisa i-UHV, ukukhiqizwa kwemishini, ukuklama kobunjiniyela, ukwakhiwa nokusebenza.
Unyaka owodwa nengxenye ngemva kokusebenza ngempumelelo kwephrojekthi yokubonisa ukuhanjiswa kwe-UHV AC, iphrojekthi yokubonisa kagesi ye-Xiangjiaba-Shanghai ±800 kV UHV DC yaqalwa ukusebenza ngoJulayi 8 kulo nyaka.Kuze kube manje, izwe lethu liqala ukungena enkathini ye-hybrid ye-ultra-high voltage AC ne-DC, futhi umsebenzi wokulungiselela ukwakhiwa kwegridi yamandla aphezulu kakhulu usulungile.
"Inethiwekhi emithathu eqondile, emithathu enezingqimba nendandatho eyodwa" izotholakala.
Intatheli iyaqonda kusukela ku-state grid corporation, inkampani ye-uhv "yeminyaka eyishumi nambili yeminyaka emihlanu" ihlela "izintathu eziqondile nezithathu ezivundlile kanye nendandatho eyodwa" ibhekisela ku-XiMeng, isigxobo, i-Zhang Bei, isisekelo samandla asenyakatho ye-shaanxi ngokusebenzisa i-uhv emithathu yobude. ac channel eya “eShayina ezintathu” kungaba amalahle asenyakatho, amanzi aseningizimu-ntshonalanga kanye nogesi ngokusebenzisa iziteshi ezintathu eziphambanayo ze-uhv ac ukuya enyakatho yeChina, maphakathi neChina kanye nokudluliselwa kwenethiwekhi yeringi ye-Yangtze river delta uhv.“Ezintathu ezivundlile” yi-Mengxi – Weifang, Jinzhong – Xuzhou, Ya 'an – southern Anhui iziteshi ezintathu ezivundlile;“Inethiwekhi yendandatho eyodwa” yi-Huainan – Nanjing – Taizhou – Suzhou – Shanghai – North Zhejiang – South Anhui – Huainan Yangtze River Delta UHV double ring network.
Umgomo we-State Grid Corporation uwukwakha igridi eqinile ehlakaniphile enegridi yamandla ehambisanayo ye-“Sanhua” UHV njengesikhungo, igridi yamandla kagesi e-Northeast UHV kanye negridi yamandla kagesi yaseNorthwest 750kV njengesiphetho sokudlulisa, ukuxhuma izisekelo ezinkulu zamandla amalahle, izisekelo ezinkulu zikagesi wamanzi, ezinkulu. izisekelo zamandla enuzi nezisekelo ezinkulu zamandla avuselelekayo, kanye nokuxhumanisa ukuthuthukiswa kwamagridi kagesi kuwo wonke amazinga ngo-2020.
Ngaphansi kwalolu hlelo, ukutshalwa kwezimali kwe-UHV kuzofinyelela ku-270 billion yuan eminyakeni emihlanu ezayo, kusho abahlaziyi.Lokhu ukukhuphuka okuphindwe ka-13 ngaphezu kwama-yuan ayizigidi eziyizinkulungwane ezingama-20 etshalwe ngesikhathi soHlelo Lweminyaka Emihlanu lwe-11.Isikhathi soHlelo Lweminyaka Eyi-12 Lweminyaka Emihlanu sizoba yisigaba esibalulekile sokuthuthukiswa kwegridi kagesi ye-UHV yaseChina.
Umthamo wokudlulisa onamandla wokwakha igridi eqinile ehlakaniphile
Ukwakhiwa kwegridi kagesi ye-UHV AC-DC kuyingxenye ebalulekile yesixhumanisi sokudlulisa segridi ehlakaniphile eqinile, futhi kuyingxenye ebalulekile yokwakhiwa kwegridi ehlakaniphile eqinile.Kubaluleke kakhulu ukukhuthaza ukwakhiwa kwegridi eqinile ehlakaniphile.
Kulinganiselwa ukuthi ngo-2020, isizinda sikagesi wamalahle entshonalanga sihlela ukuthumela izigidi ezingama-234 kW zamandla amalahle ezindaweni ezimaphakathi nesempumalanga, lapho kuzothunyelwa izigidi eziyi-197 kW ngegridi ye-UHV AC-DC.Amandla wamalahle e-Shanxi kanye nenyakatho yeShaanxi alethwa nge-UHV AC, amandla amalahle e-Mengxi, i-Ximeng ne-Ningdong alethwa nge-UHV AC-DC hybrid, futhi amandla amalahle e-Xinjiang nase-Eastern Mongolia alethwa ngokuqondile kugridi yamandla “ I-North China, i-East China ne-Central China” nge-UHV.
Ngaphezu kwamandla amalahle endabuko, i-UHV izophinde yenze umsebenzi wokudlulisa ugesi ngamanzi.Ngesikhathi esifanayo, amandla omoya adluliswa ngesiteshi sokudlulisa sangaphandle sesisekelo samandla wamalahle futhi adluliselwe kugridi yamandla "i-Sanhua" ngokuhlanganisa umoya nomlilo, okwazi ukubona ukumuncwa kwamandla omoya ebangeni elibanzi endaweni. entshonalanga futhi ikhuthaze ukuthuthukiswa nokusetshenziswa kwamandla omoya kanye namanye amandla avuselelekayo.
