Ultra-yakakwira-voltage magetsi ekutapurirana muChina

Ultra-yakakwira-voltage Electricity Kuendesa Kuwedzera kweiyo ac ese uye DC kugona kunoenderera kuitira kuti uenderane nechizvarwa chekushandisa chinoda kuderedza kurasikirwa kwekutapurirana. Kuvandudzwa kweDalarbonization kunozoitika kubva pakutsiva kwechizvarwa chakadzika, chiri padyo nemhenderekedzo yemahombekombe emazuva ano nehurefu hwekusvibiswa kusvibiswa pedyo neSimba Zvigadzirwa.

Kumashure

Kubva 2004, kushandiswa kwemagetsi muChina kwave kuri kukura pachiyero chisina kumboitika nekuda kwekukura kwekukurumidza kwemaindasitiri. Kupererwa kwakakomba mu2005 kwakakanganisa kushanda kwemakambani mazhinji eChinese. Kubva ipapo, China ine china nehasha yakaisa mumagetsi mumagetsi kuitira kuti izadzise zvinodiwa kubva kuindasitiri uye nokudaro kuchengetedza kukura kwehupfumi. Yakaiswa chizvarwa chechizvarwa chakamhanya kubva ku443 kusvika kumagumo e2004 kusvika kuAJapan manhamba emagetsi, kana nguva yegore. 6,800-6,900 tw na 2018 kubva pa4,690 tw kubva ku12,056 gw muHydropower, uye 40Gw nyuchi-soro nyika

Kuendesa uye kugovera

Pakutapurirana uye kugovera chikamu, nyika yakatarisa pakuwedzera kugona uye kuderedza kurasikirwa na:

1. Kuendesa kure-kure-kure-yakakwira-voltage yakananga ikozvino (UHVDC) uye Ultra-yakakwira-voltage kuchinjisa zvazvino (UHVAC) kutapurirana

2.Installing yakakwirira-inoshanda Amorphous Metal Shanders

UHV kutapurirana pasi rese

UHV kutapurirana uye nhamba yeUHVAC zvitupa zvakatovakwa kare munzvimbo dzakasiyana dzepasi. Semuenzaniso, 2,362 km Mitsetse yekuyedza yezviyero zvakasiyana-siyana inowanikwawo munyika dzakawanda. Nekudaro, mazhinji emitsetse iyi arikushanda parizvino ari kuderera voltage nekuda kweisina kukwana simba remagetsi kana zvimwe zvikonzero. Kune mashoma mienzaniso yeUHVDC. Kunyangwe paine akawanda ± 500 kv (kana pazasi) matunhu epasi rose, iyo chete mashandiro emashandisirwo epamusoro tression system pa19352 km murefu muna 2018) uye Itaiip MuRussia, basa rekuvaka pane imwe km refu km mikana MuUSA pakutanga kwe1970s a 1333 KV Powerline yakarongwa kubva kuCelilo Converter Station kuenda kuHoover Dam. Nechinangwa ichi kwenguva pfupi yekuyedza Powerline pedyo neCelilo Converter Station yakavakwa, asi mutsara weHover Hover hauna kuzombovakwa.

Zvikonzero zve UHV Kuendesa muChina

Chisarudzo cheChina chekuenda kuUHV kutapurirana zvinobva pane chokwadi chekuti simba zviwanikwa zviri kure nemutoro nzvimbo. Ruzhinji rwe hydropower zviwanikwa zviri kumavirazuva, uye marasha ari kuchamhembe kwakadziva kumadokero, asi mitoro yakakura iri kumabvazuva uye zasi. Kuti uderedze kutapurirana kurasikirwa kune imwe nhanho inotarisirwa, UHV kutapurirana sarudzo ine musoro. Sezvo State Grid Corporation yeChina yakaziviswa pamusangano wepasi rose wechipiri paUHV Simba muBeijing, China inoisa REB Billion (Inenge Mabhiriyoni 88 bhiriyoni) muUHV kukura pakati pezvino kusvika 2020.

Kuitwa kweUHV Grid kunoita kuti kuvakwa kwetsva, kuchenesa, zvakanyatsoita simba rezvirongo zvinodyarwa kure kubva kunzvimbo dzevagari. Zvidyarwa zvechikuru zvidyarwa pamhenderekedzo yegungwa ichavambwa. Izvi zvichadzikira huwandu hwese hwazvino hwekusvibiswa, pamwe nekusvibiswa kwakaitwa nevagari vemo mukati meguta. Iko kushandiswa kweiyo hombe masimba masofa anopa magetsi ekupisa zvakare kusvibisa kune imwe nzira yekudzvanywa neyekuwedzera kweiyo mhepo yekudzvanya

Uhv zvapera zvinopedzwa kana kuvakwa

Kubva pa2021, mashandiro euhv matunhu ari:

 

Iyo yekuvakwa / mukugadzirira UHV mitsara ndeye:

 

Kupokana pamusoro peUHV

Pane kukakavara pamusoro pekuti kuvakwa kwakataurwa neHurumende Grid Corporation yeChina chirongwa chekuva chinoita monopolistic uye kurwisa simba rekugadzirisa simba.

Pamberi pechibvumirano cheParis, icho chakaita kuti zvive zvakakosha kuti zviitwe kunze kwehasha, mafuta uye gasi, kwave kukakavara pamusoro peUhv kubvira 2004 apo iyo State Grid Corporation yeChina yakafungidzirwa kuti pfungwa yekuvaka yeUHV. Iko kukakavara kwakatarisana ne uhpac nepo zano rekuvaka Uhvdc rave rakagamuchirwa zvakanyanya.Zvakanyanya kupokana nyaya ndiyo ina yakanyorwa pazasi.

1. Kuchengetedzeka uye Kuverengeka Nyaya: Nekuvakwa kwezvinhu zvakanyanya uye zvakanyanya UHV Transpit Shipment Like, Simba rine mugomba rakakomberedza rudzi rwese rwakabatana zvakanyanya uye zvakanyanya. Kana tsaona ichiitika mumutsara mumwe, zvakaoma kudzikisira pesvedzero kune imwe nzvimbo diki. Izvi zvinoreva kuti mikana yeBlack ari kukwira. Zvakare, inogona kunge iri panjodzi yekugandara.
   
2. Chinyorwa cheMusika: Chimwe Chese UHV Transpt Litter Pasi parizvino vari kushanda parizvino voltage nekuti hapana mukana wakakwana. Iko kugona kwekureba kwekureba kwekureba kunoda kuwedzera-kudzika. Kunyangwe ruzhinji rwemarasha ari kuchamhembe kwakadziva kumadokero, zvakaoma kuvaka masimba masimba zvirimwa ipapo nekuti ivo vanoda huwandu hwakawanda hwemvura uye icho chinhu chigadziko chakanyanya kuchamhembe kwakadziva kumadokero. Uye zvakare nekuvandudzwa kwehupfumi kuWest China, kudiwa kweMagetsi kwave kuri kwemakore ano.
3. Nyaya dzezvakatipoteredza uye dzinoshanda Imwe nyaya ndeyekuchinja kwekushandisa. Kushandisa kwakabatanidzwa kupisa uye simba kumucheto kwemushandisi kuri kuwedzera simba pane kushandisa simba kubva kure kure kutapurika tambo.
   
4. Nyaya yehupfumi: Iyo yakazara mari inofungidzirwa kuve 270 bhiriyoni yebation (yakatenderedza US $ 40 bhiriyoni), iyo yakawanda inodhura pane kuvaka njanji nyowani yekufambisa yezororo.

Sezvo uhv inopa mukana wekutamisa simba rekuvandudza kubva kunzvimbo dziri kure nezvinogona kuitika kune yakakura mwaka mhepo simba uye photovoltaics. SGCC inotaura nezve zvinogona kugona simba kune simba remhepo re200 GW mune Xinjiang dunhu.
