China yasvika padanho guru mukuchengetwa kwesimba kwegrid-scalenekupedzwa kwechivako chikuru kupfuura zvose pasi rosebhatiri rekuyerera kwevanadium redox (VRFB)Iri muJimusar County, Xinjiang, basa guru iri, rinotungamirwa neChina Huaneng Group, rinobatanidza sisitimu yemabhatiri eVRFB ye200 MW / 1 GWh nepurazi guru rezuva re1 GW.
Ichimiririra mari inosvika mabhiriyoni 3.8 emadhora ekuAmerica (inenge mamiriyoni 520 emadhora), chirongwa ichi chinokura munzvimbo yakakura mahekita 1,870. Kana changotanga kushanda, chinotarisirwa kugadzira magetsi akachena e1.72 TWh pagore, zvichibatsira kudzikira kukuru kwematani anopfuura mamiriyoni 1.6 eCO₂ pagore.
Basa guru rekuisa VRFB uku nderekugadzirisa nguva dzekushanda kweVRBsimba rezuvaYakagadzirwa kwemaawa mashanu yekubuda kwemagetsi nguva dzose, inoshanda sechinodzivirira uye chinosimbisa grid yemuno. Kugona uku kwakakosha zvikuru muXinjiang ine zviwanikwa zvakawanda, uko simba rezuva nemhepo rave richisangana nematambudziko kubva mukuderedzwa kwesimba remagetsi uye miganhu yekufambisa magetsi.
1. Kukwira kweKuchengetera Zvinhu & Tekinoroji Dzakabatana
Kukura kwechirongwa ichi cheVRFB redox flow battery system kunoratidza kukosha kwenyika yese kwekugadzirisa simba kwenguva refu kuti risanganisire simba rinogadziriswazve zvinobudirira. Kunyange zvazvo tekinoroji yeVRFB battery ichibudirira mukushandiswa kunoda hupenyu hurefu hwema cycle, kuchengetedzeka ne electrolyte yakawanda, uye kuora kushoma kwemakumi emakore, mamwe matekinoroji akaita seayaMabhatiri eLithium Iron Phosphate (LFP)isimba guru muzvikamu zvakasiyana.
IyoSisitimu yebhatiri yeLFP, kufanana nedzatinonyanya kushandisa, dzinopa zvakanakira zvakasiyana:
- ⭐Simba Rakawanda: Inopa simba rakawanda muchikamu chidiki, yakakodzera kuiswa munzvimbo shoma.
- ⭐Kushanda Kwakanaka Kwerwendo Rwekutenderera: Kuderedza kurasikirwa kwesimba panguva yekuchaja/kuburitsa simba.
- ⭐ Kuchengetedzwa Kwakaratidzwa:Inozivikanwa nekugadzikana kwakanyanya kwekupisa uye makemikari.
- ⭐ Kushanda Kwemari Pakutasva Bhasikoro Zuva Nezuva: Inoshanda zvakanyanya pakushandisa zuva nezuva pakuchaja/kuburitsa mvura yakaita se peak shaving uye frequency regulation.
2. Kubatanidza Tekinoroji dzeGridhi Yakagadzikana
VRFBs uyeKuchengetera bhatiri reLFPkazhinji vanopindirana, kwete vakwikwidzi vakananga. VRFB yakakodzera kuchengetedza kwenguva refu (maawa anopfuura mana, pamwe nemazuva) uye mapurojekiti apo hupenyu hwemakumi emakore hunonyanya kukosha. LFP inopenya mukushandiswa kunoda simba rakawanda, mhinduro nekukurumidza, uye kushanda zvakanaka kwebhasikoro rezuva nezuva (kazhinji maawa maviri kusvika mana). Pamwe chete, mhinduro idzi dzakasiyana-siyana dzekuchengetedza simba dzinoumba musimboti wegridi yakasimba, ine simba rinogona kuvandudzwa.
Chirongwa chikuru cheVRFB cheChina chiratidzo chakajeka: kuchengetedza kwakakura kwenguva refu hakusisiri pfungwa, asi ichokwadi chakakosha chekushanda. Sezvo kudiwa kwekugadzikana kwegrid uye kubatanidzwa kunowedzera pasi rose, kushandiswa kweVRFB nemakambani epamusoro-soro.bhatiri reLFPmasisitimu achave akakosha kune ramangwana remagetsi rinogara kwenguva refu.
