Pa Seputembala 15, mwambo woyambira ntchito yokonzekera Zhejiang Jiande Pumped Storage Power Station yokhala ndi mphamvu zokwana ma kilowatts 2.4 miliyoni unachitikira ku Meicheng Town, Jiande City, Hangzhou, komwe ndi malo akuluakulu osungiramo magetsi omwe akumangidwa ku East China. Miyezi itatu yapitayo, mayunitsi onse asanu ndi limodzi a Changlongshan Pumped Storage Power Station yokhala ndi mphamvu zokwana ma kilowatts 2.1 miliyoni adangoyamba kugwira ntchito ku Anji County, Huzhou City, makilomita 170 kuchokera kumeneko.
Pakadali pano, Chigawo cha Zhejiang chili ndi mapulojekiti ambiri osungiramo zinthu zopopedwa ku China. Pali malo osungiramo zinthu zopopedwa 5 omwe akugwira ntchito, mapulojekiti 7 omwe akumangidwa, ndi mapulojekiti opitilira 20 omwe ali mu gawo lokonzekera, kusankha malo ndi kumanga.
"Zhejiang ndi chigawo chokhala ndi mphamvu zochepa, komanso chigawo chomwe chimagwiritsa ntchito mphamvu zambiri. Chakhala chikukakamizidwa kwambiri kuti chitsimikizire chitetezo cha mphamvu ndi kupezeka kwa magetsi. M'zaka zaposachedwa, pansi pa 'dual carbon', ndikofunikira kumanga njira yatsopano yamagetsi yokhala ndi mphamvu zatsopano zomwe zikuwonjezeka pang'onopang'ono, zomwe zimapangitsa kuti pakhale kupsinjika kwakukulu pakumeta peak. Malo osungira magetsi opompedwa omwe amangidwa, omwe akumangidwa ndipo akukonzekera ku Zhejiang akhoza kukhala ndi gawo lofunikira pakumeta peak, kudzaza zigwa, kusintha kwa ma frequency, ndi zina zotero ku Zhejiang komanso ngakhale ku East China power grids, ndipo angathandizenso pa mphamvu ya mphepo, mphamvu ya mphepo Kupanga mphamvu ya Photovoltaic ndi magwero ena atsopano amagetsi amaphatikizidwa kuti akwaniritse mphamvu zambiri ndikusandutsa 'magetsi a zinyalala' kukhala 'magetsi apamwamba'." Pa Seputembala 23, Han Gang, mainjiniya wa Energy and Environment Research Institute of Zhejiang Development Planning Research Institute, adauza nkhani yomwe ikupitilira.
Bizinesi yotsika mtengo ya "magetsi a ma kilowatts anayi pamagetsi a ma kilowatts atatu pamagetsi"
Mphamvu imapangidwa ndikugwiritsidwa ntchito nthawi yomweyo, ndipo singasungidwe mu gridi yamagetsi. Kale, mu dongosolo la gridi yamagetsi lomwe limayang'aniridwa ndi mphamvu yotentha komanso kupanga magetsi amadzi, njira yachikhalidwe ndiyo kumanga nthawi zonse malo opangira magetsi kuti akwaniritse zosowa za kukula kwa mphamvu zamagetsi, ndikutseka mayunitsi ambiri a jenereta pamene kugwiritsa ntchito mphamvu kuli kochepa kuti asunge mphamvu. Chifukwa chake, zidzawonjezeranso zovuta pakulamulira mphamvu ndikubweretsa zoopsa zobisika ku bata ndi chitetezo cha gridi yamagetsi.
M'zaka za m'ma 1980, chifukwa cha kukula kwachuma kwa dera la Yangtze River Delta, kufunikira kwa magetsi kunakula kwambiri. Mu gridi yamagetsi ya East China, yomwe imayang'aniridwa ndi mphamvu ya kutentha, idayenera kukoka switch kuti ichepetse mphamvu pa katundu wolemera kwambiri ndikuchepetsa kutulutsa kwa mayunitsi opanga magetsi (mphamvu yotulutsa mkati mwa nthawi ya unit) pa katundu wochepa. Pachifukwa ichi, East China Power Grid idaganiza zomanga malo osungira magetsi okhala ndi mphamvu zambiri. Akatswiri afufuza malo 50 a malo osungira magetsi okhala ndi mphamvu ku Zhejiang, Jiangsu ndi Anhui. Pambuyo pofufuza mobwerezabwereza, kuwonetsa ndi kuyerekeza, malowa ali ku Tianhuangping, Anji, Huzhou kuti amange malo oyamba osungira magetsi okhala ndi mphamvu ku East China.
Mu 1986, mayunitsi opanga Tianhuangping Pumped Storage Power Station adakonzedwa ndi East China Survey and Design Institute ndipo Lipoti Lofufuza Zotheka la Zhejiang Tianhuangping Pumped Storage Power Station lidamalizidwa. Mu 1992, pulojekiti ya Tianhuangping Pumped Storage Power Station idayambitsidwa, ndipo ntchito yomanga idayamba mwalamulo mu Marichi 1994. Mu Disembala 2000, mayunitsi onse asanu ndi limodzi adayikidwa kuti apange magetsi, okhala ndi mphamvu yonse yokwana ma kilowatts 1.8 miliyoni. Nthawi yonse yomanga idatenga zaka zisanu ndi zitatu. Jiang Feng, Wachiwiri kwa Woyang'anira Wamkulu wa East China Tianhuangping Pumped Storage Co., Ltd., wakhala akugwira ntchito ku Tianhuangping Pumped Storage Power Station kwa zaka 27 kuyambira 1995. Iye adayambitsa kuti: "Malo osungira magetsi opompedwa makamaka amapangidwa ndi malo osungiramo madzi apamwamba, malo osungiramo madzi otsika, mapaipi otumizira magetsi ndi turbine yosinthira madzi. Malo osungira magetsi opompedwa amagwiritsidwa ntchito kugwiritsa ntchito mphamvu yotsala panthawi yochepa ya makina amagetsi kupompa madzi kuchokera ku malo osungiramo madzi otsika kupita ku malo osungiramo madzi apamwamba kuti asunge mphamvu yochulukirapo, ndikutulutsa madzi kuchokera ku malo osungiramo madzi apamwamba kupita ku malo osungiramo madzi otsika kuti apange magetsi pamene mphamvu ikugwiritsidwa ntchito kwambiri kapena makinawo akufunika malamulo osinthasintha, kuti apereke mphamvu yayikulu komanso ntchito zothandizira makina amagetsi. Nthawi yomweyo, chipangizocho chikupompa ndi kupanga. Panthawi yopanga magetsi, mitundu yosiyanasiyana ya kusintha kwa magwiridwe antchito ikhoza kuchitika, ndipo ntchito zosinthira zosinthika zitha kuperekedwa malinga ndi zosowa za makina kuti akwaniritse magwiridwe antchito otetezeka komanso okhazikika komanso kugwiritsa ntchito bwino mphamvu zamagetsi. "
"Pakusintha mphamvu, padzakhala kutayika kwa mphamvu. Kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito posintha magetsi pa Tianhuangping Pumped Storage Power Station kuli pafupifupi 80% chifukwa cha malo ndi zifukwa zina. Komabe, kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito posintha magetsi pa malo akuluakulu osungira magetsi ndi pafupifupi 75%, zomwe zikufanana ndi maola 4 a kilowatt pa maola 3 a kilowatt. Zikuoneka kuti sizotsika mtengo, koma kusungira magetsi pamadzi ndi ukadaulo wokhwima kwambiri, wabwino kwambiri, komanso mikhalidwe yayikulu yopangira magetsi obiriwira, otsika mpweya, oyera komanso osinthasintha." Jiang Feng adauza nkhani yowonjezereka.
Malo Osungira Magetsi Opopa Madzi a Tianhuangping ndi chitsanzo chofala cha mgwirizano wa m'madera osiyanasiyana ku Mtsinje wa Yangtze. Chifukwa cha ndalama zambiri zomwe zinagwiritsidwa ntchito pomanga malo osungira magetsi, Shanghai, Jiangsu Province, Zhejiang Province ndi Anhui Province adasaina Pangano Lopezera Ndalama Zomangira Malo Osungira Magetsi Opopa Madzi a Tianhuangping kuti agwiritse ntchito limodzi pomanga malowo. Malo osungira magetsi akamalizidwa ndikugwiritsidwa ntchito, mgwirizano wa m'madera osiyanasiyana wakhala ukuchitika nthawi zonse. Ma gridi amagetsi a m'chigawo ndi m'matauni adzalandira mphamvu zamagetsi malinga ndi kuchuluka kwa ndalama zomwe zagwiritsidwa ntchito panthawiyo ndikupereka mphamvu zamagetsi zomwe zagwiritsidwa ntchito. Malo Osungira Magetsi Opopa Madzi a Tianhuangping atamalizidwa ndikugwiritsidwa ntchito, alimbikitsa bwino kugwiritsa ntchito mphamvu zatsopano ku East China, akweza magwiridwe antchito a makina amagetsi, komanso atsimikizira chitetezo cha gridi yamagetsi ya East China.
