15 GWh yamagetsi obiriwira ochokera ku Gansu adatumizidwa posachedwa kupita ku Zhejiang.
"Iyi ndi njira yoyamba yogulitsira magetsi obiriwira a Gansu m'chigawo cha Gansu," adatero He Xiqing, Executive Director wa Gansu Electric Power Trading Company.Ntchitoyi itamalizidwa pa nsanja ya e-trading ya Beijing Power Exchange Center, mphamvu yobiriwira ya Gansu idapita molunjika ku Zhejiang kudzera pa chingwe chotumizira cha Ningdong-Shaoxing ± 800kV UHVDC.
Zolemera mu mphepo ndi mphamvu za dzuwa, mphamvu zomwe mphepo ndi mphamvu za dzuwa zimatha ku Gansu ndi 560 GW ndi 9,500 GW motsatira.Mpaka pano, mphamvu zokhazikitsidwa za mphamvu zatsopano zimakhala pafupifupi theka la chiwerengero chonse, ndipo mphamvu yogwiritsira ntchito magetsi kuchokera ku mphamvu zatsopano yawonjezeka kuchoka pa 60,2% mu 2016 mpaka 96,83% lero.Mu 2021, mphamvu zatsopano ku Gansu zidaposa 40 TWh ndipo mpweya woipa wa carbon dioxide udachepetsedwa ndi matani pafupifupi 40 miliyoni.
Kutumiza magetsi opita kum'mawa kuchokera ku Gansu kudzakwera 100 TWh pachaka
M'munsi mwa mapiri a Qilian opitilira makilomita 60 kumpoto kwa mzinda wa Zhangye, m'chigawo cha Gansu, ma turbine amphepo akuzungulira ndi mphepo.Iyi ndi Famu ya Mphepo ya Pingshanhu.'Makina onse opangira mphepo amakhala ndi masensa owongolera mphepo ndipo 'adzatsata mphepo' basi, adatero Zhang Guangtai, mkulu wa famu ya mphepo, 'famuyo imapanga 1.50 MWh yamagetsi mu ola limodzi.'
Pa Chipululu cha Gobi mumzinda wa Jinchang, mapanelo a blue photovoltaic ali mwadongosolo.Njira yolondolera imayikidwa kuti iwonetsetse kuti mapanelo asinthe ngodya yopita kudzuwa, ndikuwonetsetsa kuti dzuŵa likuwalira mwachindunji pazithunzi za photovoltaic.Zawonjezera m'badwo ndi 20% mpaka 30%.
'Bizinesi yamagetsi yoyera ikukula mwachangu komanso yayikulu,' atero a Ye Jun, Wapampando wa State Grid Gansu Electric Power.'Popanga mizere yotumizira ya UHV yotuluka kunja, magetsi ochulukirapo amaperekedwa ku Central ndi kum'mawa kwa China.'
Mu June 2017, Gansu anamaliza ndikuyamba kugwira ntchito ya Jiuquan-Hunan ±800kV UHVDC Transmission Project, chingwe choyamba chamagetsi chomwe cholinga chake ndi kutumiza mphamvu zatsopano ku China.Pa Qilian Converter Station, malekezero otumizira, magetsi obiriwira kuchokera ku Hexi Corridor amakwezedwa mpaka 800 kV kenako amatumizidwa mwachindunji ku Hunan.Pofika pano, Qilian Converter Station yatumiza magetsi okwana 94.8 TWh kupita ku Central China, zomwe zimatengera pafupifupi 50% ya magetsi otuluka kuchokera ku gridi yamagetsi ya Gansu, adatero Li Ningrui, Wachiwiri kwa Purezidenti wa EHV Company of State. Grid Gansu Electric Power ndi mutu wa Qilian converter station.
'Mu 2022, tidzakwaniritsa ndondomeko ya State Grid pa zolinga za nyengo ya China ndikulimbikitsa mwamphamvu kumanga njira yatsopano yopangira mphamvu ndi kugwiritsa ntchito magetsi pogwiritsa ntchito mizere yopatsirana ya UHV,' adatero Ye Jun. Ntchito Yopatsirana ya Gansu-Shandong ya UHVDC ili koyambirira kuvomerezedwa tsopano.Kuphatikiza apo, Gansu wasaina mapangano okhudzana ndi mgwirizano wamagetsi ndi Zhejiang ndi Shanghai, ndipo mapulojekiti opatsirana a Gansu-Shanghai ndi Gansu-Zhejiang UHV akulimbikitsidwanso.'Zikuyembekezeka kuti pakutha kwa 14th Year Planning, magetsi otuluka pachaka kuchokera ku Gansu adutsa 100 TWh,' Ye Jun adawonjezera.
Wonjezerani mphamvu zogwiritsira ntchito mphamvu mwaukhondo pogwiritsa ntchito kutumiza kogwirizana
Ku Gansu Dispatching Center, zonse zopangira magetsi zimawonetsedwa munthawi yeniyeni pazenera.'Ndi dongosolo latsopano lamphamvu lowongolera magulu amagetsi, kutulutsa kwathunthu ndi kutulutsa kwamagetsi aliwonse kumatha kuyendetsedwa mwanzeru,' adatero Yang Chunxiang, wachiwiri kwa director of Dispatching Center of State Grid Gansu Electric Power.
Kuneneratu kwa mphepo ndi mphamvu ya dzuwa ndikofunikira kwambiri pakuwongolera mwanzeru.Zheng Wei, Katswiri wamkulu wa Reliability Management ku State Grid Gansu Electric Power Research Institute, anati: "Kuneneratu kwamphamvu kwamphamvu kwatsopano ndi njira yofunikira yaukadaulo yowonetsetsa kuti mphamvu zamagetsi zikuyenda bwino komanso mokhazikika."Kutengera zotsatira zomwe zanenedweratu, malo otumizira magetsi amatha kulinganiza kuchuluka kwa magetsi ndi kuperekedwa kwa gridi yonse ndikuwongolera dongosolo lopangira mayunitsi kuti asungire malo ndikuwongolera kugwiritsa ntchito mphamvu zatsopano zopangira mphamvu.
M'zaka zaposachedwa, Gansu wamanga maukonde akulu kwambiri padziko lonse lapansi ophatikizika amphepo ndi mphamvu ya dzuwa omwe ali ndi nsanja 44 zoyezera nthawi yeniyeni, malo 18 opangira zithunzi zanyengo, ndi zowunikira 10 za haze ndi fumbi ndi zina. ndi magetsi a photovoltaic mkati mwa Hexi Corridor akhoza kuyang'aniridwa mu nthawi yeniyeni, "anatero Zheng Wei.Pofuna kukonza zolosera zam'mlengalenga ndi mphamvu ya dzuwa, State Grid idachita kafukufuku waukadaulo monga kulosera kwapakatikati kwa mphindi ya photovoltaic ultrashort-term.'Kupanga mphamvu zatsopano zapachaka zomwe zanenedweratu kumayambiriro kwa 2021 zinali 43.2 TWh pomwe 43.8 TWh zidamalizidwa, kukwaniritsa kulondola kwa pafupifupi 99%.'
Panthawi imodzimodziyo, magwero amagetsi oyendetsera nsonga zapamwamba monga kusungirako kupopera, kusungirako mphamvu zamagetsi, ndi mphamvu zotentha zothandizira kupititsa patsogolo mphamvu zatsopano zikumangidwanso.'Yumen Changma Pumped Storage Power Plant ikuphatikizidwa mu pulani yapakatikati komanso yayitali yosungiramo madzi, ndipo malo opangira magetsi opangira magetsi padziko lonse lapansi adamangidwa ndikuyikidwa ku Gansu,' adatero Yang Chunxiang. .'Mwa kuphatikiza kusungirako mphamvu ndi magetsi atsopano opanga magetsi kuti azitha kuyang'anira nsonga zapamwamba, nsonga zapamwamba zoyendetsera mphamvu zamagetsi zamagetsi zimatha kukonzedwanso kuti zikhale zolimba komanso zodalirika za mphamvu zatsopano.'
Dongosolo lothandizira mafakitale limapeza zambiri kuchokera kuzinthu zamagetsi ndi dzuwa
M'malo opangira mafakitale opanga zida zatsopano zamagetsi ku Wuwei, makina opangira magetsi opangira magetsi opitilira 80 m'litali akukwezedwa kuti akaperekedwe ku Zhangye mtunda wa makilomita oposa 200.
'M'badwo wawonjezedwa kuchokera pa 2 MW woyambirira kufika ku 6 MW ndi masamba awa,' atero a Han Xudong, Director of General Management ku Gansu Chongtong Chengfei New Materials Co., Ltd. Kwa makampani opanga magetsi, izi zikutanthauza kuti mphamvu zambiri ndi zopangidwa pamtengo wotsika.'Lero, masamba a turbine opangidwa ku Wuwei agulitsidwa ku zigawo zambiri.Mu 2021, malamulo a 1,200 seti anaperekedwa ndi mtengo wa CNY750 miliyoni.'
Zimapindulitsa mabizinesi ndikuwonjezera ndalama za anthu am'deralo."Kupanga ma turbine amphepo kumakhala kovutirapo, mabala angapo amafunikira mgwirizano wapamtima wa anthu opitilira 200," adatero Han Xudong.Lapereka ntchito zoposa 900 kwa anthu ochokera kumidzi ndi matauni apafupi.Ndi maphunziro a miyezi itatu, atha kuyamba ndi ntchitoyo ndipo aliyense amalandira CNY4,500 pafupifupi pamwezi.
Li Yumei, wokhala m'mudzi wa Zhaizi, Fengle Town, Liangzhou District, Wuwei, adalowa nawo kampaniyo ngati wogwira ntchito mu 2015 pa ntchito yoyamba yopanga masamba.'Ntchitoyi si yovuta ndipo aliyense akhoza kuyamba atamaliza maphunziro.Tsopano nditha kupeza ndalama zoposa CNY5,000 pamwezi.Pamene mukhala waluso, m’pamenenso mumapeza ndalama zochuluka.’
"Chaka chatha, anthu ammudzi mwathu adalipidwa ndalama zoposa CNY100,000 popanga magetsi a photovoltaic," adatero Wang Shouxu, wachiwiri kwa komiti ya anthu ammudzi wa Hongguang Xincun Village, Liuba Town, Yongchang County, Jinchang.Zina mwa ndalamazo zimagwiritsidwa ntchito pomanga ndi kukonza ntchito zachitukuko cha anthu m’midzi komanso kulipira malipiro a ntchito zosamalira anthu.Chigawo cha Yongchang chinalembedwa ngati chigawo choyendetsa ndege polimbikitsa mphamvu za photovoltaic zogawidwa m'chigawo cha Gansu mu August 2021. Mphamvu yoyikapo yomwe inakonzedwa ndi 0.27 GW ndipo alimi opindula akuyembekezeka kuwonjezera ndalama zawo ndi CNY1,000 pachaka.
Malinga ndi CPC Gansu Provincial Committee, Gansu aziyang'ana kwambiri pakukula kwa mafakitale amagetsi oyera ndikufulumizitsa ntchito yomanga maziko amagetsi a Hexi Corridor kuti msika wamagetsi watsopano pang'onopang'ono ukhale dalaivala wamkulu komanso mzati wachuma chakomweko. .
