Ultra-Chuma-Magetsi Magetsi ku China

Kutumiza magetsi kwambiri (kufalitsa magetsi (UHV) kugwiritsidwa ntchito ku China kuyambira 2009 kufalitsa magetsi onse (ac) ndi magetsi (DC) pa mtunda wautali wolekanitsa magetsi ndi ogula. Kukula kwa AC ndi DC Kukula Kumapitilirabe Kuti Muzigwirizana ndi Mbadwo Kuti Kugwiritsa Ntchito Kumafunikira Pochepetsa kutayika kwina. Kusintha kwa Dekabori kumachitika chifukwa cha m'badwo wa m'badwo wamphamvu kwambiri, komwe kuli pafupi ndi gombe, monga m'badwo wamakono wamakono popanda kuipitsidwa kocheperako pafupi ndi mphamvu.

Chiyambi

Kuyambira 2004, kugwiritsa ntchito magetsi ku China kwakhala kukukula chifukwa cha kukula kwa ma ekitala a mafakitale. Kusafunikira kwakukulu mu 2005 kunali atachitapo kanthu ka makampani ambiri aku China. Kuyambira nthawi imeneyo, China yakhala ndi magetsi kwambiri popanga magetsi kuti akwaniritse kufunikira kwa mafakitale ndipo chifukwa chake kulipiritsa zachuma. Kuyika kwa zaka zowayika kwatha kuyambira 443 GW kumapeto kwa 2004 mpaka 793 GW kumapeto kwa gawo limodzi mwa magawo awiri a Japan. Kuti tifikire 6,800-600 thh pofika chaka cha 2018

Kufalitsa ndi kugawa

Pa kufalitsa ndi kugawa mbali ina, dzikolo layang'ana kwambiri kukulitsa mphamvu ndikuchepetsa kutayika:

1. Kugwetsa mtunda wautali wa Ultra-Hight Counter Proad (UHVDC) ndi volt-voliyumu yopitilira muyeso (UHVVAC)

2.

Kutumiza kwa UHV Padziko Lonse Lapansi

Kufalitsa kwa UHV ndi zingapo za mabwalo a Uhvac adapangidwa kale m'maiko osiyanasiyana. Mwachitsanzo, 2,362 Km wa mabwalo a madera 1,150 adamangidwa m'mbuyomu, ndi 427 km madera okwana 1,000 apangidwa ku Japan (Kita-Iwaki Borterline). Mizere yoyesera yamakamba osiyanasiyana imapezekanso m'maiko ambiri. Komabe, ambiri mwa mizere iyi ikugwira ntchito pa voliyumu yotsika chifukwa chongofuna mphamvu kapena zifukwa zina. Pali zitsanzo zochepa za Uhvdc. Ngakhale pali ma ± 500 kV (kapena pansipa) kuzungulira padziko lonse lapansi, madera okhawo omwe ali pamwamba pa nthawi iyi ndi magetsi a Hydro-Quapu atapita mu 2018) ndi ichoipi ± 600 KV. Ku Russia, ntchito yomanga 2400 km kutalika kwa 2400 kc 750 kc mzere, HVDC Ekibastuz-Center idayamba mu 1978 koma sizinathe. Ku USA kumayambiriro kwa 1970s Powernine wamphamvu wa 1333 KV adakonzekera kuchokera ku Celilo Converder Station kupita ku Houver Damu. Pachifukwa ichi choyeserera kwakanthawi pafupi ndi Celilo Osinthira malo adamangidwa, koma mzere waku Hover Damu sunamangidwe.

Zifukwa za kufananira kwa UHV ku China

Kusankha kwa China kuti mupite ku kufalikira kwa UHV kumatengera kuti mphamvu zake zili kutali ndi malo ogulitsira. Ambiri mwa mitundu ya hymweyo ili kumadzulo, ndipo malasha ali kumpoto chakumadzulo, koma akuluakulu ali Kummawa ndi Kumwera. Kuchepetsa kutaya zotayika ku mulingo woyenera, kufalikira kwa UHV ndi kusankha komveka bwino. Monga momwe boma liliri la China lidalengezedwa pamsonkhano wapadziko lonse wa 2009 pa UHV Grour Kutumiza ku Beajing, China biliyoni (pafupifupi US biliyoni) kulowa mu UHV Pakati pa Im / 2020.

Kukhazikitsa kwa UHV Grid kumathandizira kumanga kwatsopano, mphamvu yoyeta bwino, yabwino kwambiri ya Mbadwo Wazipatso kutali ndi anthu. Zomera zokulirapo m'mphepete mwa nyanja zimapuma pantchito. Izi zidzachepetsa chiwopsezo chaposachedwa, komanso kuipitsidwa ndi nzika mkati mwa nyumba za utatu. Kugwiritsa ntchito mphamvu zazikuluzikulu zapakati popereka kutentha kwa magetsi sikungodetsa nkhawa nthawi yozizira komwe kumapangitsa kuti pakhale njira yothandizirana ndi magalimoto ambiri ku China.

Mabwalo a UHV Omaliza kapena Omangidwa

Pakati pa 2021, mabwalo a AHV AHV ndi awa:

 

Womanga / pokonzekera uHV mizere ndi iyi:

 

Mikangano pa Uhv

Pali mikangano yopitilira kaya kapangidwe kamene kapangidwe ka State Grid Corporation of China ndi njira yoti ikhale yopanga kwambiri ndikulimbana ndi zomwe zidasintha.

Asanachitike pa Paris, zomwe zidapangitsa kuti zitheke pa nthawi yopanga malasha, mafuta, pomwepo pakhala mikangano pa Uhv kuyambira pa 2004 pomwe bungwe la United Corm Corporation of China idafuna lingaliro la zomangamanga za Uhv. Mtsutsowu wakhala ukuyang'ana ku UHVAC pomwe lingaliro lakumanga Uhvdc lalandiridwa kwambiri. Zotsatira zambiri zotsatizana kwambiri ndi zinayi ndi zinayi zomwe zidatchulidwa pansipa.

1. Chitetezo ndi Zodalirika: Ndi ntchito yomanga mizere yofananira ndi UHV, mphamvu yotchedwa mtundu wonsewo imalumikizidwa kwambiri. Ngati ngozi zimachitika mu mzere umodzi, ndizovuta kuchepetsa chidwi ndi dera laling'ono. Izi zikutanthauza kuti mwayi wodakulira ukukwera. Komanso, zitha kukhala pachiwopsezo chachikulu cha uchigawenga.
   
2. Magazini: Mizere yonse ina yonse ya UHV padziko lonse lapansi ikugwira ntchito pa voliyumu yotsika chifukwa palibe kufunsa kokwanira. Ngakhale zida zambiri za malasha ndi kumpoto chakumadzulo, ndizovuta kumanga mbewu zamoto pamenepo chifukwa zimafunikira madzi ambiri ndipo ndiye gawo lochepa kwambiri kumpoto chakumadzulo China. Komanso ndi chitukuko cha zachuma ku West China, kufunikira kwa magetsi kwakhala kukuchulukirachulukira.
3. Nkhani zachilengedwe komanso zoyendetsera bwino: Akatswiri ena amati mizere ya UHV siyisunga malo owonjezera ogulitsa magetsi a Counts and Moorth. Vuto lina ndi kufalitsa mphamvu. Kugwiritsa ntchito kutentha ndi mphamvu pa wogwiritsa ntchito kumatha mphamvu kwambiri kuposa kugwiritsa ntchito mphamvu kuchokera ku mizere yayitali.
   
4. Kutulutsa Kwachuma: Kugulitsa ndalama zonse kumakutidwa kukhala 270 Bilion RMB (kuzungulira US $ 40 biliyoni), zomwe ndizokwera mtengo kwambiri kuposa kumanga njanji yatsopano yamoto.

Monga Uhv imapereka mwayi woti usatumidwenso mphamvu yobwezeretsanso madera akutali ndi kuthekera kwakukulu kwa makonzedwe akuluakulu a mphamvu ya mphepo ndi Photovoltactions. SGCC imatchulapo mphamvu yomwe mungakwaniritse mphamvu ya 200 gw mu dera la Xinjiang.

Sichuan D & F Enernec CO., LTD.Monga wopanga zowongolera zamagetsi opitira, zigawo zamagetsi zamagetsi, zokhazikika basi za basi, zokhazikika pa basi yosungunuka, ndife amodzi mwa ogulitsa mabasi a State UhvDD. Kuti mumve zambiri, chonde pitani patsamba langa kuti mumve zambiri za zinthuzo.
