UHV yeChina ichaumba matatu akatwasuka, matatu akachinjika uye imwe mhete network pateni

Musi waNyamavhuvhu 12, State Grid Corporation yakazivisa kuti Jindongnan - Nanyang - Jingmen UHV AC mutyairi uye purojekiti yekuratidzira yakanga yapasa bvunzo yekugamuchirwa yenyika - zvichireva kuti UHV haisisiri mu "bvunzo" uye "yekuratidzira" nhanho.Chinese magetsi grid ichapinda zviri pamutemo nguva ye "ultra-high voltage", uye kubvumidzwa uye kuvakwa kwemapurojekiti anotevera kunotarisirwa kukurumidza.

Zvinoenderana nechirongwa chekuvaka chirongwa cheUHV chakaburitswa neHurumende Grid Corporation pazuva rimwe chete, ne2015, "Three Huas" (North, East neCentral China) UHV gidhi remagetsi richavakwa, richigadzira "matatu akatwasuka, matatu akatwasuka uye akatwasuka. one ring network”, uye 11 UHV yakananga mapurojekiti ekufambisa azvino achapedzwa.Maererano nehurongwa, mari yeUHV ichasvika 270 bhiriyoni yuan mumakore mashanu anotevera, vaongorori vakati.

Nhamba yepasi rose inotungamira tekinoroji zviyero

Musi waNdira 6, 2009, 1000 kV Jindong-Nanyang Jingmen UHV AC yekuratidzira chirongwa chakaiswa mukushanda kwekutengesa.Iyi purojekiti ndiyo yepamusoro-soro nhanho yemagetsi pasi rose, iyo yepamusoro-soro tekinoroji level uye yekufambisa magetsi purojekiti ine yakakwana yakazvimirira kodzero yepfuma.Iri zvakare purojekiti yekutanga uye yekutanga-yakakwira-voltage yekufambisa purojekiti yakavakwa uye kuiswa mukushanda munyika yedu.

Sekureva kwemunhu akakodzera anoona nezve State Grid Corporation, makumi mapfumbamwe muzana emidziyo yeprojekiti inogadzirwa mudzimba, zvinoreva kuti China yakanyatso hunyanzvi hwekutanga tekinoroji yeUHV AC kutapurirana uye inokwanisa kugadzira akawanda eUHV AC michina. .

Pamusoro pezvo, kuburikidza nemuitiro uyu wepurojekiti, State Grid Corporation yakatsvaga ikaparura UHV AC transmission technology standard system ine zviyero makumi manomwe nenomwe muzvikamu zvinomwe kekutanga pasi rose.Imwe chiyero chenyika chakadzokororwa, 15 yenyika zviyero uye makumi manomwe nenhatu zviyero zvebhizinesi zvakapihwa, uye 431 patents yakagamuchirwa (237 yakabvumidzwa).China yakamisa nzvimbo inotungamira pasi rose muminda yeUHV yekufambisa tekinoroji yekutsvaga, kugadzira michina, dhizaini yeinjiniya, kuvaka uye kushanda.

Gore rimwe nehafu mushure mekushanda kwakabudirira kweprojekti yekuratidzira yeUHV AC, Xiangjiaba-Shanghai ±800 kV UHV DC chirongwa chekuratidzira chekufambisa chakaitwa musi wa8 Chikunguru gore rino.Kusvika pari zvino, nyika yedu inotanga kupinda munguva yakasanganiswa ye-ultra-high voltage AC neDC, uye basa rekugadzirira kuvaka kwe-ultra-high voltage grid rakagadzirira.

"Matatu akatwasuka, matatu akachinjika uye imwe mhete network" ichaitika.

Mutori wenhau anonzwisisa kubva kuhurumende grid corporation, kambani yehv "yegumi nemaviri-makore mashanu" kuronga "matatu akatwasuka uye matatu akatwasuka uye mhete imwe" inoreva kubva kuXiMeng, stake, Zhang Bei, yekuchamhembe shaanxi simba base kuburikidza neatatu longitudinal uhv. ac chiteshi kuenda ku "China nhatu" angave marasha ekuchamhembe, maodzanyemba kwakadziva kumadokero kwemvura uye magetsi kuburikidza nematatu anochinjika uhv ac chiteshi kuenda kuchamhembe kweChina, nechepakati peChina neYangtze rwizi delta uhv ring network transmission.“Three horizontal” iMengxi – Weifang, Jinzhong – Xuzhou, Ya 'an – maodzanyemba kweAnhui matatu akachinjika ekufambisa nzira;"One ring network" ndiHuainan - Nanjing - Taizhou - Suzhou - Shanghai - North Zhejiang - South Anhui - Huainan Yangtze River Delta UHV kaviri ring network.

Chinangwa cheState Grid Corporation ndechekuvaka gidhi rakasimba rakasimba rine "Sanhua" UHV synchronous power grid sepakati, Northeast UHV power grid uye Northwest 750kV power grid sekupera kwekufambisa, kubatanidza mabhesi makuru emarasha, mabhesi makuru emagetsi emvura, mahombe. mabhesi emagetsi enyukireya uye mabhesi makuru emagetsi anovandudzwa, uye kuronga kuvandudzwa kwemagidhi emagetsi pamatanho ese panosvika 2020.

Pasi pechirongwa ichi, mari yeUHV ichasvika 270 bhiriyoni yuan mumakore mashanu anotevera, vaongorori vakadaro.Uku kuwedzera kakapetwa kagumi nenhatu pamusoro pemakumi maviri emabhiriyoni emayuan akaiswa mukati mechikamu chegumi nerimwe cheChirongwa cheMakore mashanu.Nguva yechigumi nembiri yeChirongwa cheMakore mashanu ichave chikamu chakakosha cheChina chekugadzirwa kwemagetsi eUHV.

Yakasimba kutapurirana kugona kuvaka yakasimba smart grid

Kuvakwa kweUHV AC-DC magetsi grid chikamu chakakosha chekutumira chinongedzo cheiyo yakasimba smart grid, uye chikamu chakakosha chekuvakwa kweiyo yakasimba smart grid.Izvo zvakakosha zvikuru kusimudzira kuvakwa kweiyo yakasimba smart grid.

Zvinofungidzirwa kuti panosvika 2020, iyo yekumavirira marasha simba base inoronga kutumira 234 miriyoni kW yemarasha kumatunhu epakati nekumabvazuva, ayo 197 miriyoni kW achatumirwa kuburikidza neUHV AC-DC grid.Simba remarasha reShanxi nekuchamhembe kweShaanxi rinounzwa kuburikidza neUHV AC, simba remarasha reMengxi, Ximeng neNingdong rinounzwa kuburikidza neUHV AC-DC hybrid, uye simba remarasha reXinjiang neEastern Mongolia rinounzwa zvakananga kugetsi remagetsi re“ North China, East China neCentral China” kuburikidza neUHV.

Pamusoro pesimba remarasha echinyakare, UHV ichaitawo basa rekufambisa kwehydropower.Panguva imwecheteyo, simba remhepo rinofambiswa kuburikidza nekunze kwekufambisa chiteshi chesimba remarasha uye kuendeswa kune "Sanhua" gidhi remagetsi kuburikidza nemhepo nemoto bundling, iyo inogona kuona kunyudzwa kwesimba remhepo munzvimbo yakafara munzvimbo. kumadokero uye kusimudzira hukuru-hukuru kusimudzira uye kushandiswa kwesimba remhepo uye rimwe simba rinodzokororwa.
