Ngomhla we-12 ka-Agasti, i-State Grid Corporation yazisa ukuba i-Jindongnan - i-Nanyang - i-Jingmen UHV AC pilot kunye neprojekthi yokubonisa iphumelele uvavanyo lwelizwe lokwamkelwa - oku kuthetha ukuba i-UHV ayisekho "kuvavanyo" kunye "nomboniso" wezigaba.Igridi yombane yaseTshayina iya kungena ngokusesikweni kwixesha “lombane ophezulu kakhulu”, kwaye ukuvunywa nokwakhiwa kweeprojekthi ezilandelayo kulindeleke ukuba kukhawuleziswe.
Ngokutsho kwesicwangciso sokwakhiwa kweprojekthi ye-UHV evezwe yi-State Grid Corporation ngosuku olufanayo, ngo-2015, "i-Three Huas" (eNyakatho, eMpuma kunye ne-Central China) igridi yamandla e-UHV iya kwakhiwa, yenze "isithathu esithe nkqo, ezintathu ezithe tye kunye ne-horizontal. uthungelwano lweringi enye”, kunye ne-11 yeeprojekthi zothumelo oluthe ngqo ze-UHV ziya kugqitywa.Ngokutsho kwesicwangciso, utyalo-mali lwe-UHV luya kufikelela kwi-270 yeebhiliyoni ze-yuan kwiminyaka emihlanu ezayo, abahlalutyi bathi.
Inani lemigangatho yobugcisa ehamba phambili kumazwe ngamazwe
NgoJanuwari 6, 2009, i-1000 kV ye-Jindong-Nanyang Jingmen UHV iprojekthi yokubonisa i-AC yafakwa kumsebenzi worhwebo.Le projekthi lelona nqanaba lamandla ombane liphezulu kwihlabathi, elona nqanaba lobugcisa liphezulu kunye neprojekthi yothumelo lwamandla onxibelelwano enamalungelo apheleleyo azimeleyo epropathi enomgangatho ophezulu wokuqonda.Ikwayiprojekthi yokuqala kunye neprojekthi yokuqala yokuhanjiswa kwamandla ombane aphezulu kakhulu eyakhiwe yaza yasetyenziswa kwilizwe lethu.
Ngokutsho komntu ochaphazelekayo ophethe i-State Grid Corporation, i-90% yezixhobo zeprojekthi ziveliswa ngaphakathi, oku kuthetha ukuba i-China ibambe ngokupheleleyo iteknoloji engundoqo yokuhanjiswa kwe-UHV AC kwaye inamandla okuvelisa izixhobo ze-UHV AC. .
Ukongeza, ngokusebenzisa le projekthi, i-State Grid Corporation iye yaphanda kwaye yaphakamisa inkqubo ye-UHV AC yothumelo lwe-teknoloji esemgangathweni equka imigangatho engama-77 kwiindidi ezi-7 okokuqala ngqa emhlabeni.Umgangatho omnye wesizwe uye wahlaziywa, imigangatho yesizwe eyi-15 kunye nemigangatho yoshishino engama-73 ikhutshiwe, kwaye amalungelo awodwa omenzi wechiza angama-431 amkelwe (ama-237 agunyazisiwe).I-China iseke indawo ehamba phambili kumazwe ngamazwe kwiinkalo zophando lwe-UHV yosasazo lwetekhnoloji, ukuveliswa kwezixhobo, uyilo lobunjineli, ukwakhiwa kunye nokusebenza.
Unyaka onesiqingatha emva kokusebenza ngempumelelo kweprojekthi yokubonisa ukuhanjiswa kwe-UHV AC, iXiangjiaba-Shanghai ±800 kV UHV DC yeprojekthi yokubonisa yaqaliswa ukusebenza nge-8 kaJulayi kulo nyaka.Ukuza kuthi ga ngoku, ilizwe lethu liqala ukungena kwixesha le-hybrid ye-ultra-high-voltage ye-AC kunye ne-DC, kwaye umsebenzi wokulungiselela ukwakhiwa kwegridi yombane we-ultra-high ulungile.
"Inethiwekhi ezintathu ezithe nkqo, ezintathu ezithe tyaba kunye nekhonkco enye" ziya kuzaliseka.
Intatheli uyayiqonda ukusuka corporation igridi karhulumente, inkampani uhv "yeshumi elinesibini iminyaka emihlanu" isicwangciso "emithathu nkqo kunye ezintathu ezithe tye kunye nentsimbi enye" ibhekisela XiMeng, isibonda, Zhang Bei, isiseko samandla shaanxi emantla ngokusebenzisa ezintathu longitudinal uhv. itshaneli ye-ac ukuya “kwiTshayina ezintathu” nokuba ngamalahle asemantla, amanzi akumzantsi-ntshona kunye nombane ngokusebenzisa ijelo le-uhv ac elinqamlezayo ukuya emantla eTshayina, kumbindi weTshayina kunye nothungelwano lweringi yeringi ye-Yangtze River delta uhv.“Ezintathu ezithe tyaba” yiMengxi – Weifang, Jinzhong – Xuzhou, Ya 'an – emazantsi eAnhui amajelo osasazo axwesileyo amathathu;"Inethiwekhi enye yendandatho" yi-Huainan - Nanjing - Taizhou - Suzhou - Shanghai - North Zhejiang - South Anhui - Huainan Yangtze River Delta UHV inethiwekhi yeringi ephindwe kabini.
Injongo ye-State Grid Corporation kukwakha igridi eyomeleleyo ene-"Sanhua" ye-UHV yegridi yamandla ehambelanayo njengeziko, igridi yamandla e-Northeast UHV kunye ne-Northwest 750kV igridi yamandla njengesiphelo sothumelo, ukudibanisa iziseko ezinkulu zamandla amalahle, iziseko ezinkulu zombane wamanzi, ezinkulu. iziseko zamandla enyukliya kunye neziseko ezinkulu zamandla ahlaziyekayo, kunye nokulungelelanisa uphuhliso lweegridi zamandla kuwo onke amanqanaba ngowama-2020.
Ngaphantsi kwesicwangciso, utyalo-mali lwe-UHV luya kufikelela kwi-270 yebhiliyoni ye-yuan kwiminyaka emihlanu ezayo, abahlalutyi bathi.Oku kukwanda okuphindwe ka-13 ngaphezulu kwe-20 yeebhiliyoni zeeyuan etyalwe ngexesha le-11 leSicwangciso seMinyaka emiHlanu.Isithuba se-12 seSicwangciso seMinyaka emiHlanu siya kuba sisigaba esibalulekileyo sophuhliso lwegridi yombane ye-UHV yaseTshayina.
Umthamo wothumelo olomeleleyo wokwakha igridi eyomeleleyo
Ukwakhiwa kwegridi yombane ye-UHV AC-DC yinxalenye ebalulekileyo yothungelwano lwekhonkco lothungelwano lwegridi eyomeleleyo, kunye nenxalenye ebalulekileyo yolwakhiwo lwegridi eyomeleleyo.Kubaluleke kakhulu ukukhuthaza ukwakhiwa kwegridi eyomeleleyo.
Kuqikelelwa ukuba ngo-2020, isiseko samandla amalahle asentshona siceba ukuthumela i-234 yezigidi ze-kW zamandla amalahle kwimimandla esembindini nasempuma, apho i-197 yezigidi zekW iya kuthunyelwa ngegridi ye-UHV AC-DC.Amandla amalahle e-Shanxi kunye namantla eShaanxi ahanjiswa nge-UHV AC, amandla amalahle e-Mengxi, i-Ximeng kunye ne-Ningdong ahanjiswa nge-UHV AC-DC hybrid, kunye namandla amalahle e-Xinjiang kunye ne-Eastern Mongolia ahanjiswa ngokuthe ngqo kwigridi yamandla " Emantla eTshayina, eMpuma China nakuMbindi weTshayina” nge-UHV.
Ukongeza kumandla amalahle emveli, i-UHV iya kwenza umsebenzi wokuhambisa umbane ngamanzi.Kwangaxeshanye, amandla omoya ahanjiswa ngomjelo wangaphandle wothumelo lwesiseko samandla amalahle kwaye adluliselwe kwigridi yamandla "iSanhua" ngokusebenzisa umoya kunye nokudibanisa umlilo, onokuqonda ukufunxwa kwamandla omoya kuluhlu olubanzi kwindawo entshona kunye nokukhuthaza uphuhliso olukhulu kunye nokusetyenziswa kwamandla omoya kunye namanye amandla ahlaziyekayo.
