Ku ya 12 Kanama, ikigo cya Leta gishinzwe imiyoboro rusange cyatangaje ko umushinga w’indege wa Jindongnan - Nanyang - Jingmen UHV AC watsindiye ikizamini cy’igihugu - bivuze ko UHV itakiri mu cyiciro cy '“ikizamini” n' “imyigaragambyo”.Umuyoboro w'amashanyarazi w'Abashinwa uzinjira ku mugaragaro "ultra-high voltage", kandi biteganijwe ko kwemeza no kubaka imishinga izakurikiraho byihuta.
Dukurikije gahunda yo kubaka umushinga UHV wagaragajwe n’ikigo cya Leta gishinzwe amashanyarazi kuri uwo munsi, kugeza mu 2015, hazubakwa umuyoboro w’amashanyarazi “Three Huas” (Amajyaruguru, Uburasirazuba n’Ubushinwa) umuyoboro umwe w'impeta ”, na 11 UHV itaziguye yohereza imishinga izarangira.Abasesenguzi bavuze ko ukurikije gahunda, ishoramari rya UHV rizagera kuri miliyari 270 mu myaka itanu iri imbere.
Umubare mpuzamahanga wambere wambere mubuhanga
Ku ya 6 Mutarama 2009, umushinga wo kwerekana ibizamini 1000 kV Jindong-Nanyang Jingmen UHV AC washyizwe mubikorwa byubucuruzi.Uyu mushinga nu rwego rwo hejuru rwa voltage kwisi, urwego rwa tekiniki rwateye imbere kandi umushinga wo gukwirakwiza amashanyarazi hamwe nuburenganzira bwuzuye bwumutungo wubwenge.Numushinga wo gutangira numushinga wambere wa ultra-high voltage wohereza kandi ugashyirwa mubikorwa mugihugu cyacu.
Nk’uko byatangajwe n'umuntu ubishinzwe ushinzwe ikigo cya Leta gishinzwe amashanyarazi, 90% by'ibikoresho by'uyu mushinga bikorerwa mu gihugu imbere, bivuze ko Ubushinwa bumaze kumenya neza ikoranabuhanga ry'ibanze ryo kohereza UHV AC kandi rifite ubushobozi bwo gukora cyane ibikoresho bya UHV AC .
Byongeye kandi, binyuze muriyi myitozo yumushinga, ikigo cya leta Grid cyakoze ubushakashatsi kandi gitanga uburyo bwa tekinoroji ya tekinoroji ya UHV AC igizwe nibipimo 77 mubyiciro 7 kunshuro yambere kwisi.Ihame rimwe ry’igihugu ryaravuguruwe, hashyizweho ibipimo 15 by’igihugu n’ibipimo 73 by’ibigo, naho 431 byemewe (237 byemewe).Ubushinwa bwashyizeho umwanya mpuzamahanga ku isonga mu bijyanye n’ubushakashatsi bw’ikoranabuhanga rya UHV, gukora ibikoresho, igishushanyo mbonera, ubwubatsi n’imikorere.
Nyuma yumwaka umwe nigice nyuma yo gukora neza umushinga wo kwerekana amashanyarazi UHV AC, umushinga wo kwerekana amashanyarazi Xiangjiaba-Shanghai ± 800 kV UHV DC watangiye gukoreshwa ku ya 8 Nyakanga uyu mwaka.Kugeza ubu, igihugu cyacu gitangiye kwinjira mubihe bivangavanze bya ultra-high voltage AC na DC, kandi imirimo yo kwitegura kubaka amashanyarazi ya ultra-high voltage yose iriteguye.
“Bitatu bihagaritse, bitatu bitambitse hamwe n'umuyoboro umwe w'impeta” bizagerwaho.
Umunyamakuru asobanukirwa n’ikigo cya leta gishinzwe imiyoboro ya leta, isosiyete ya uhv “cumi na kabiri yimyaka itanu” iteganya “bitatu bihagaritse na bitatu bitambitse kandi impeta imwe” bivuga kuri XiMeng, imigabane, Zhang Bei, ikigo cy’ingufu za shaanxi mu majyaruguru binyuze muri uhv eshatu ndende umuyoboro wa ac ujya kuri "Ubushinwa butatu" haba mu makara y’amajyaruguru, mu majyepfo y’iburengerazuba n’amashanyarazi binyuze mu muyoboro wa transvers uhv ac ugana mu majyaruguru yUbushinwa, Ubushinwa bwo hagati n’umugezi wa Yangtze delta uhv.“Bitatu bitambitse” ni Mengxi - Weifang, Jinzhong - Xuzhou, Ya 'an - Amajyepfo ya Anhui imiyoboro itatu itambitse;“Umuyoboro umwe w'impeta” ni Huainan - Nanjing - Taizhou - Suzhou - Shanghai - Amajyaruguru ya Zhejiang - Amajyepfo ya Anhui - Huainan Yangtze Umugezi Delta UHV umuyoboro w’impeta ebyiri.
Intego ya Leta ya Grid Corporation ni ukubaka umuyoboro ukomeye wubwenge hamwe na "Sanhua" UHV umuyoboro w’amashanyarazi nkikigo, amashanyarazi y’amajyaruguru y’amajyaruguru UHV hamwe n’amashanyarazi yo mu majyaruguru y’iburengerazuba 750kV nkumuyoboro wogukwirakwiza, uhuza amashanyarazi akomeye y’amakara, ibirindiro binini by’amashanyarazi, binini ibirindiro bya nucleaire n’ingufu nini zishobora kuvugururwa, no guhuza iterambere ry’amashanyarazi mu nzego zose muri 2020.
Abasesenguzi bavuze ko muri iyi gahunda, ishoramari rya UHV rizagera kuri miliyari 270 mu myaka itanu iri imbere.Ubu ni ubwiyongere bwikubye inshuro 13 miriyari 20 zashowe mugihe cya gahunda yimyaka 11 yimyaka itanu.Igihe cya 12 cyimyaka 5 yimyaka 5 kizaba icyiciro cyingenzi cyiterambere ryu Bushinwa UHV.
Ubushobozi bukomeye bwo kohereza kubaka gride ikomeye yubwenge
Kubaka amashanyarazi ya UHV AC-DC nigice cyingenzi cyoguhuza imiyoboro ikomeye ya gride ifite ubwenge, nigice cyingenzi cyubwubatsi bukomeye bukomeye.Ningirakamaro cyane guteza imbere iyubakwa rya gride ikomeye yubwenge.
Biteganijwe ko mu mwaka wa 2020, amashanyarazi y’amakara y’iburengerazuba arateganya kohereza miliyoni 234 kilo y’amashanyarazi mu turere two hagati n’iburasirazuba, muri yo miliyoni 197 kWizoherezwa binyuze mu muyoboro wa UHV AC-DC.Amashanyarazi y’amakara ya Shanxi n’amajyaruguru ya Shaanxi atangwa binyuze muri UHV AC, ingufu z’amakara ya Mengxi, Ximeng na Ningdong zitangwa binyuze mu mvange ya UHV AC-DC, naho amakara y’amakara ya Sinayi na Mongoliya y’iburasirazuba ashyikirizwa amashanyarazi ya “ Amajyaruguru y'Ubushinwa, Ubushinwa n'Ubushinwa bwo hagati ”binyuze muri UHV.
Usibye ingufu z'amakara gakondo, UHV izakora kandi umurimo wo kohereza amashanyarazi.Muri icyo gihe, ingufu z'umuyaga zanyuzwa mu muyoboro wohereza hanze w'amashanyarazi y’amakara hanyuma ikoherezwa kuri gride ya “Sanhua” hifashishijwe umuyaga n'umuriro, ushobora kumenya kwinjiza ingufu z'umuyaga mu buryo bwagutse muri iburengerazuba no guteza imbere iterambere rinini no gukoresha ingufu zumuyaga nizindi mbaraga zishobora kuvugururwa.
