Pa August 12, State Grid Corporation inalengeza kuti Jindongnan - Nanyang - Jingmen UHV AC woyendetsa ndi pulojekiti yowonetsera adadutsa mayeso ovomerezeka a dziko - kutanthauza kuti UHV salinso mu "mayeso" ndi "ziwonetsero" siteji.Gulu lamagetsi aku China lidzalowa m'nthawi ya "ultra-high voltage", ndipo kuvomereza ndi kumanga mapulojekiti otsatirawa akuyembekezeka kufulumizitsa.
Malinga ndi ndondomeko yomanga pulojekiti ya UHV yomwe inavumbulutsidwa ndi State Grid Corporation tsiku lomwelo, pofika chaka cha 2015, "Three Huas" (North, East ndi Central China) UHV magetsi grid adzamangidwa, kupanga "atatu ofukula, atatu yopingasa ndi netiweki imodzi ya mphete”, ndi ma projekiti 11 a UHV otumizira mwachindunji amalizidwa.Malinga ndi ndondomekoyi, ndalama za UHV zidzafika 270 biliyoni m'zaka zisanu zikubwerazi, akatswiri adanena.
A angapo mayiko kutsogolera luso mfundo
Pa Januware 6, 2009, projekiti yowonetsera kuyesa kwa 1000 kV Jindong-Nanyang Jingmen UHV AC idayikidwa pamalonda.Pulojekitiyi ndi yamphamvu kwambiri padziko lonse lapansi, yaukadaulo wapamwamba kwambiri komanso pulojekiti yotumiza mphamvu zolumikizirana yomwe ili ndi ufulu wodziyimira pawokha wazinthu zaluso.Ndiwonso pulojekiti yoyambira komanso pulojekiti yoyamba yotumizira ma voltages okwera kwambiri yomwe idamangidwa ndikuyikidwa m'dziko lathu.
Malinga ndi munthu woyenerera amene amayang'anira State Grid Corporation, 90% ya zida za polojekitiyi zimapangidwa m'nyumba, zomwe zikutanthauza kuti China yadziwa bwino luso laukadaulo la kufala kwa UHV AC ndipo imatha kupanga zida zambiri za UHV AC. .
Kuphatikiza apo, kudzera muzochita za polojekitiyi, State Grid Corporation yafufuza ndikupereka malingaliro aukadaulo waukadaulo wa UHV AC wokhala ndi miyezo 77 m'magulu 7 kwa nthawi yoyamba padziko lapansi.Mulingo umodzi wadziko lonse wasinthidwa, miyezo 15 yamayiko ndi 73 zamabizinesi zaperekedwa, ndipo ma Patent 431 avomerezedwa (237 avomerezedwa).China yakhazikitsa malo otsogola padziko lonse lapansi pakufufuza kwaukadaulo wa UHV, kupanga zida, kapangidwe kaukadaulo, zomangamanga ndi ntchito.
Patatha zaka chimodzi ndi theka kuchokera pamene polojekiti yowonetsera kufala kwa UHV AC yachitika bwino, pulojekiti ya Xiangjiaba-Shanghai ya ± 800 kV UHV DC inayamba kugwira ntchito pa July 8 chaka chino.Pakalipano, dziko lathu likuyamba kulowa mu nthawi yosakanizidwa ya ultra-high voteji AC ndi DC, ndipo ntchito yokonzekera kumanga gridi yamagetsi apamwamba kwambiri yakonzeka.
"Zitatu zoyimirira, zitatu zopingasa ndi mphete imodzi" zidzakwaniritsidwa.
Mtolankhani akumvetsa kuchokera boma gululi corporation, kampani ya uhv "khumi ndi ziwiri zaka zisanu" dongosolo "atatu ofukula ndi atatu yopingasa ndi mphete imodzi" amatanthauza kuchokera XiMeng, pamtengo, Zhang Bei, kumpoto shaanxi mphamvu m'munsi kudzera atatu longitudinal uhv. ac njira yopita ku "China zitatu" mwina malasha a kumpoto, madzi akumwera chakumadzulo ndi magetsi kudzera munjira zitatu zodutsa uhv ac kupita kumpoto kwa China, pakati pa China ndi njira yotumizira ma ring network ya Yangtze river delta uhv."Atatu yopingasa" ndi Mengxi - Weifang, Jinzhong - Xuzhou, Ya 'an - kum'mwera kwa Anhui njira zitatu zopingasa zodutsa;"One ring network" ndi Huainan - Nanjing - Taizhou - Suzhou - Shanghai - North Zhejiang - South Anhui - Huainan Yangtze River Delta UHV double ring network.
Cholinga cha State Grid Corporation ndi kupanga gululi wamphamvu wanzeru ndi "Sanhua" UHV synchronous mphamvu grid monga likulu, Northeast UHV mphamvu grid ndi Northwest 750kV magetsi grid monga kutha kufalitsa, kulumikiza maziko mphamvu malasha, lalikulu hydropower maziko, lalikulu. Maziko a mphamvu za nyukiliya ndi maziko akuluakulu ongowonjezwdwanso, ndikugwirizanitsa chitukuko cha ma grids pamagulu onse pofika 2020.
Pansi pa ndondomekoyi, ndalama za UHV zidzafika pa 270 biliyoni m'zaka zisanu zikubwerazi, akatswiri adanena.Uku ndi kuwonjezereka kowirikiza ka 13 kuposa ma yuan mabiliyoni 20 omwe adayikidwa mu nthawi ya 11th Five-year Planning.Nthawi ya 12 ya Mapulani a Zaka Zisanu idzakhala gawo lofunikira pakukulitsa grid ya China ya UHV.
Mphamvu yotumizira mwamphamvu kuti mupange gridi yolimba yanzeru
Kupanga kwa gridi yamagetsi ya UHV AC-DC ndi gawo lofunikira panjira yolumikizira ya gridi yamphamvu yanzeru, komanso gawo lofunikira pakumanga gridi yolimba yanzeru.Ndikofunikira kwambiri kulimbikitsa kumanga gridi yolimba yanzeru.
Akuti pofika chaka cha 2020, mphamvu ya malasha yakumadzulo ikukonzekera kutumiza mphamvu ya malasha yokwana 234 miliyoni kumadera apakati ndi kum'mawa, pomwe 197 miliyoni kW idzatumizidwa kudzera mu gridi ya UHV AC-DC.Mphamvu ya malasha ya Shanxi ndi kumpoto kwa Shaanxi imaperekedwa kudzera mu UHV AC, mphamvu ya malasha ya Mengxi, Ximeng ndi Ningdong imaperekedwa kudzera mu UHV AC-DC wosakanizidwa, ndi mphamvu ya malasha ya Xinjiang ndi Eastern Mongolia imaperekedwa mwachindunji ku gridi yamagetsi " North China, East China ndi Central China” kudzera mu UHV.
Kuphatikiza pa mphamvu zamakala zamakala, UHV idzagwiranso ntchito yotumiza mphamvu zamagetsi pamadzi.Panthawi imodzimodziyo, mphamvu ya mphepo imafalitsidwa kudzera mu njira yakunja yotumizira mphamvu ya malasha ndikutumizidwa ku gridi yamagetsi ya "Sanhua" pogwiritsa ntchito mphepo ndi moto, zomwe zimatha kuzindikira kuyamwa kwa mphamvu ya mphepo mumtundu wambiri. kumadzulo ndikulimbikitsa chitukuko chachikulu ndi kugwiritsa ntchito mphamvu zamphepo ndi mphamvu zina zongowonjezwdwa.
