UHV-ga Shiinaha wuxuu samayn doonaa saddex toosan, saddex siman iyo hal qaab shabakadeed giraan ah

Agoosto 12, Shirkadda Grid State waxay ku dhawaaqday in Jindongnan - Nanyang - Jingmen UHV AC pilot iyo mashruuca bandhiggu uu ka gudbay imtixaankii aqbalaadda qaranka - taasoo la micno ah UHV hadda kuma jiro "imtixaanka" iyo "muujinta" marxaladaha.Shabakadda korontada Shiinaha ayaa si rasmi ah u geli doonta xilliga "korontada aadka u sareysa", ansixinta iyo dhismaha mashaariicda xiga ayaa la filayaa in la dardargeliyo.

Sida laga soo xigtay qorshaha dhismaha mashruuca UHV oo ay shaaca ka qaaday shirkadda State Grid isla maalintaas, 2015, "Saddex Huas" (Waqooyi, Bari iyo Bartamaha Shiinaha) UHV korantada ayaa la dhisi doonaa, sameynta "saddex toosan, saddex siman iyo hal giraan ah network”, iyo 11 UHV mashruuc gudbin toos ah hadda waa la dhamaystiri doonaa.Sida qorshuhu yahay, maalgashiga UHV wuxuu gaari doonaa 270 bilyan yuan shanta sano ee soo socota, falanqeeyayaasha ayaa yiri.

Tiro ka mid ah heerarka farsamada hormuudka ah ee caalamiga ah

Janaayo 6, 2009, 1000 kV Jindong-Nanyang Jingmen UHV AC mashruuca bandhigga tijaabada ayaa la galiyay hawlgal ganacsi.Mashruucani waa heerka ugu sarreeya ee tamarta adduunka, heerka farsamo ee ugu horumarsan iyo mashruuca gudbinta awoodda isgaarsiinta oo leh xuquuq madaxbannaan oo madax-bannaan oo dhammaystiran.Sidoo kale waa mashruucii bilawga ahaa iyo mashruucii ugu horeeyay ee korontadu kor u kacayso ee dalkeena laga hirgaliyay.

Sida laga soo xigtay qofka ay khusayso ee mas'uulka ka ah shirkadda State Grid, 90% qalabka mashruuca waxaa lagu soo saaraa gudaha, taas oo macnaheedu yahay in Shiinuhu uu si buuxda u bartay farsamada asaasiga ah ee gudbinta UHV AC oo uu leeyahay awoodda wax soo saarka ballaaran ee qalabka UHV AC. .

Intaa waxaa dheer, iyada oo loo marayo ku dhaqanka mashruucan, State Grid Corporation ayaa cilmi baaris ku samaysay oo soo jeedisay nidaamka halbeegga tignoolajiyada gudbinta ee UHV AC oo ka kooban 77 heerar oo 7 qaybood ah markii ugu horreysay adduunka.Hal halbeeg oo heer qaran ah ayaa dib loo eegay, 15 heer qaran ah iyo 73 halbeeg ganacsi ayaa la soo saaray, waxaana la aqbalay 431 shatiyo (237 waa la oggolaaday).Shiinaha ayaa aasaasay booska hogaaminaya caalamiga ah ee dhinacyada cilmi baarista tignoolajiyada gudbinta UHV, soosaarka qalabka, naqshadeynta injineernimada, dhismaha iyo hawlgalka.

Hal sano iyo badh ka dib hawlgalkii guusha ee mashruuca bandhigga gudbinta UHV AC, Xiangjiaba-Shanghai ± 800 kV UHV DC mashruuca bandhigga gudbinta ayaa la galiyay July 8 ee sanadkan.Ilaa hadda, waddankeenu wuxuu bilaabaa inuu galo xilliga isku-dhafka ah ee korantada ultra-sare AC iyo DC, iyo shaqada diyaarinta ee dhismaha koronto-sare oo dhan waa diyaar.

"Saddex toosan, saddex siman iyo hal shabakad giraan ah" ayaa la xaqiijin doonaa.

Weriyuhu wuxuu ka fahamsan yahay shirkadda gobolka ee gobolka, shirkadda uhv "qorshaha shan iyo tobnaad" "saddex toosan iyo saddex siman iyo hal giraan ah" waxaa loola jeedaa XiMeng, saamiga, Zhang Bei, saldhigga tamarta shaanxi waqooyiga iyada oo loo marayo saddex uhv dherer ah ac channel ilaa "saddexda Shiinaha" mid dhuxul waqooyi, biyaha koonfur-galbeed iyo koronto iyada oo loo marayo saddex transverse uhv ac channel waqooyiga Shiinaha, bartamaha Shiinaha iyo Yangtze delta uhv giraanta network gudbinta."Saddex toosan" waa Mengxi - Weifang, Jinzhong - Xuzhou, Ya 'an - koonfurta Anhui saddex kanaal gudbin toosan;"Hal giraan ah" waa Huainan - Nanjing - Taizhou - Suzhou - Shanghai - Waqooyiga Zhejiang - Koonfurta Anhui - Huainan Yangtze River Delta UHV shabakad labanlaab giraan ah.

Hadafka Shirkadda State Grid waa in la dhiso shabakad caqli badan oo leh "Sanhua" UHV koronto isku xiran oo ah xarunta, korontada Waqooyi-bari UHV iyo korantada Waqooyi-galbeed ee 750kV sida dhamaadka gudbinta, isku xirka saldhigyada waaweyn ee tamarta dhuxusha, saldhigyada tamarta biyaha waaweyn, waaweyn saldhigyada tamarta nukliyeerka iyo saldhigyada tamarta la cusboonaysiin karo ee waaweyn, iyo isku dubaridka horumarinta xadhkaha korantada ee dhammaan heerarka 2020.

Qorshahan, maalgashiga UHV wuxuu gaari doonaa 270 bilyan yuan shanta sano ee soo socota, falanqeeyayaasha ayaa yiri.Tani waa koror 13-laab ah oo ka badan 20 bilyan yuan oo la maalgaliyay intii lagu jiray 11-aad muddada Qorshaha Shanta Sano.Muddada Qorshaha Shanta Sano ee 12aad waxa ay noqon doontaa wejiga muhiimka ah ee horumarinta korontada UHV ee Shiinaha.

Awood gudbinta xooggan si loo dhiso shabakad caqli badan oo xooggan

Dhismaha shabakada korantada UHV AC-DC waa qayb muhiim ah oo ka mid ah isku xirka gudbinta ee xariijimo caqli badan, iyo qayb muhiim ah oo ka mid ah dhismaha shabakad caqli badan.Waa muhiimad weyn in kor loo qaado dhismaha shabakad caqli badan.

Waxa la qiyaasayaa in marka la gaadho 2020, saldhiga tamarta dhuxusha galbeed uu qorshaynayo inuu 234 milyan kW oo dhuxul ah u diro gobolada dhexe iyo bariga, taas oo 197 milyan kW ka mid ah loo diri doono xadhkaha UHV AC-DC.Awoodda dhuxusha ee Shanxi iyo waqooyiga Shaanxi waxaa lagu bixiyaa UHV AC, awoodda dhuxusha Mengxi, Ximeng iyo Ningdong waxaa lagu bixiyaa UHV AC-DC hybrid, iyo awoodda dhuxusha ee Xinjiang iyo Bariga Mongolia waxaa si toos ah loo gaarsiiyaa koronto ee " Waqooyiga Shiinaha, Shiinaha Bari iyo Bartamaha Shiinaha" iyada oo loo marayo UHV.

Marka laga soo tago tamarta dhuxusha ee dhaqameed, UHV waxay sidoo kale qaban doontaa hawsha gudbinta tamarta biyaha.Isla mar ahaantaana, awoodda dabaysha waxaa lagu kala qaadaa iyada oo loo marayo marinka gudbinta dibadda ee saldhigga tamarta dhuxusha waxaana loo gudbiyaa "Sanhua" koronto iyada oo loo marayo dabaysha iyo xirmooyinka dabka, taas oo xaqiijin karta nuugista tamarta dabaysha ee kala duwanaansho ballaaran galbeedka iyo kor u qaadida horumarinta baaxadda weyn iyo ka faa'iidaysiga tamarta dabaysha iyo tamarta kale ee la cusboonaysiin karo.
