Ma ʻAukake 12, ua hoʻolaha ka State Grid Corporation ua hala ʻo Jindongnan - Nanyang - Jingmen UHV AC pilote a me ka papahana hōʻikeʻike i ka hōʻike ʻae aupuni - ʻo ia hoʻi ʻaʻole ʻo UHV i loko o nā pae "hōʻike" a me "hōʻike".E komo maoli ana ka mana mana Kina i ke au o ka "ultra-high voltage", a ua manaʻo ʻia e hoʻolōʻihi ʻia ka ʻae a me ke kūkulu ʻana i nā papahana ma hope.
Wahi a ka papahana hana UHV i hōʻike ʻia e ka State Grid Corporation ma ka lā hoʻokahi, ma ka makahiki 2015, e kūkulu ʻia ka "Three Huas" (North, East and Central China) UHV power grid, e hana ana i "ʻekolu kū pololei, ʻekolu ākea a hoʻokahi pūnaewele apo", a e hoʻopau ʻia nā papahana hoʻouna pololei 11 UHV i kēia manawa.Wahi a ka hoʻolālā, hiki i ka hoʻopukapuka UHV ke piʻi i 270 biliona yuan i nā makahiki ʻelima e hiki mai ana, wahi a nā mea loiloi.
He helu o nā kūlana ʻenehana alakaʻi honua
Ma Ianuali 6, 2009, ua hoʻokomo ʻia ʻo 1000 kV Jindong-Nanyang Jingmen UHV AC hōʻike hōʻike papahana i ka hana ʻoihana.ʻO kēia papahana ka pae kiʻekiʻe o ka volta ma ka honua, ka pae ʻenehana kiʻekiʻe loa a me ka papahana hoʻoili mana kamaʻilio me nā kuleana waiwai naʻauao kūʻokoʻa.ʻO ia ka papahana hoʻomaka a me ka papahana hoʻoili uila ultra-kiʻekiʻe mua i kūkulu ʻia a hoʻokomo ʻia i loko o ko mākou ʻāina.
Wahi a ka mea kūpono e mālama ana i ka State Grid Corporation, ʻo 90% o nā mea hana o ka papahana i hana ʻia ma ka home, ʻo ia hoʻi ua mākaukau piha ʻo Kina i ka ʻenehana koʻikoʻi o ka hoʻouna ʻana o UHV AC a loaʻa iā ia ka hiki ke hana nui i nā lako UHV AC. .
Eia kekahi, ma o kēia hana papahana, ua noiʻi a ua noi ʻo State Grid Corporation i ka UHV AC transmission technology standard system i loaʻa i nā kūlana 77 i 7 mau ʻāpana no ka manawa mua ma ka honua.Ua hoʻoponopono hou ʻia kekahi maʻamau aupuni, 15 mau kūlana aupuni a me 73 mau ʻoihana ʻoihana i hoʻopuka ʻia, a ua ʻae ʻia nā patent 431 (237 ua ʻae ʻia).Ua hoʻokumu ʻo Kina i ke kūlana alakaʻi honua ma nā kahua o ka noiʻi ʻenehana hoʻouna UHV, hana ʻenehana, hoʻolālā ʻenekinia, kūkulu a me ka hana.
Hoʻokahi makahiki a me ka hapa ma hope o ka holomua ʻana o ka papahana hōʻike hōʻike UHV AC, ua hoʻokomo ʻia ka papahana hōʻike hōʻike hōʻike Xiangjiaba-Shanghai ± 800 kV UHV DC i ka lā 8 Iulai i kēia makahiki.I kēia manawa, hoʻomaka ko mākou ʻāina e komo i ka wā hybrid o ka ultra-high voltage AC a me DC, a ua mākaukau nā hana hoʻomākaukau no ke kūkulu ʻana i ka ultra-high voltage grid.
"ʻEkolu kūpaʻa, ʻekolu ākea a me hoʻokahi apo pūnaewele" e ʻike ʻia.
Hoʻomaopopo ka mea kākau moʻolelo mai ka hui o ka moku'āina, ʻo ka hui o uhv "ʻumikūmālua ʻelima makahiki" e hoʻolālā i kahi "ʻekolu kūpaʻa a ʻekolu hoʻi a me hoʻokahi apo" e pili ana mai XiMeng, stake, Zhang Bei, ʻākau shaanxi kumu ikehu ma o ʻekolu uhv longitudinal. ac i ka “Kina ʻekolu” a i ʻole ka lanahu akau, ka wai komohana hema a me ka uila ma o ʻekolu awāwa uhv ac a hiki i Kina akau, Kina waena a me ke kahawai ʻo Yangtze delta uhv ring network transmission.“ʻEkolu ākea” ʻo Mengxi – Weifang, Jinzhong – Xuzhou, Yaʻan – hema ʻo Anhui ʻekolu awāwa hoʻouna;"Hoʻokahi pūnaewele apo" ʻo Huainan - Nanjing - Taizhou - Suzhou - Shanghai - North Zhejiang - South Anhui - Huainan Yangtze River Delta UHV pūnaewele apo pālua.
ʻO ka pahuhopu o State Grid Corporation ʻo ia ke kūkulu ʻana i kahi mākia akamai ikaika me ka "Sanhua" UHV pūnaewele mana like ke kikowaena, Northeast UHV power grid a me Northwest 750kV power grid e like me ka hopena o ka hoʻouna ʻana, e hoʻopili ana i nā kumu mana lanahu nui, nā kumu wai nui, nui. nā waihona mana nuklea a me nā kumu ikehu hou hou, a me ka hoʻonohonoho ʻana i ka hoʻomohala ʻana o nā mana mana ma nā pae āpau e 2020.
Ma lalo o ka hoʻolālā, hiki i ka hoʻopukapuka UHV ke hōʻea i 270 biliona yuan i nā makahiki ʻelima e hiki mai ana, wahi a nā mea loiloi.He 13 ka piʻi ʻana o kēia ma mua o ka 20 biliona yuan i hoʻopukapuka ʻia i ka wā 11th Five-Year Plan.E lilo ana ka 12th Five-Year Plan i wahi koʻikoʻi o ka hoʻomohala ʻana i ka mana UHV o Kina.
ʻO ka hiki ke hoʻoili ikaika e kūkulu i kahi mākia akamai ikaika
ʻO ke kūkulu ʻia ʻana o ka mana UHV AC-DC kahi ʻāpana koʻikoʻi o ka loulou hoʻouna o ka mākia akamai ikaika, a he ʻāpana hoʻohui o ke kūkulu ʻana i ka māka akamai ikaika.He mea koʻikoʻi nui ka paipai ʻana i ke kūkulu ʻia ʻana o ka māka akamai ikaika.
Ua manaʻo ʻia ma ka makahiki 2020, hoʻolālā ka waihona mana lanahu komohana e hoʻouna i 234 miliona kW o ka mana lanahu i nā ʻāpana waena a me ka hikina, a ʻo 197 miliona kW e hoʻouna ʻia ma o ka UHV AC-DC grid.Hāʻawi ʻia ka mana lanahu o Shanxi a me Shaanxi ʻĀkau ma o UHV AC, ʻo ka mana lanahu o Mengxi, Ximeng a me Ningdong e hāʻawi ʻia ma o UHV AC-DC hybrid, a hāʻawi pololei ʻia ka mana lanahu o Xinjiang a me Eastern Mongolia i ka mana mana o " Kina ʻĀkau, Kina Hikina a me Kina Waena” ma o UHV.
Ma waho aʻe o ka mana lanahu kuʻuna, e hana pū ʻo UHV i ka hana o ka hoʻoili ʻana i ka hydropower.I ka manawa like, hoʻoili ʻia ka mana makani ma o ke kahawai hoʻoili waho o ke kumu mana lanahu a hoʻouna ʻia i ka mana mana "Sanhua" ma o ka makani a me ke ahi puʻupuʻu, hiki ke hoʻomaopopo i ka absorption o ka mana makani ma kahi ākea ākea i ka komohana a hāpai i ka hoʻomohala nui a me ka hoʻohana ʻana i ka mana makani a me nā ikehu hou.
