Pumped storage hydropower station ndiyo inonyanya kushandiswa uye yakura tekinoroji muhukuru-hukuru kuchengetedza simba, uye iyo yakaiswa simba rechiteshi chemagetsi inogona kusvika pagigawatt level. Parizvino, iyo pumped storage power station ine yakakura kwazvo kukura kukura pasirese.
Pumped storage hydropower station ine yakakura uye yakagadzikana tekinoroji uye yakakwirira yakazara mabhenefiti. Inowanzoshandiswa pakuveura ndebvu uye kumira. Pumped storage hydropower station ndiyo inonyanya kushandiswa uye yakura tekinoroji muhukuru-hukuru kuchengetedza simba, uye iyo yakaiswa simba rechiteshi chemagetsi inogona kusvika pagigawatt level.
Zvinoenderana nehuwandu husina kukwana hweiyo simba rekuchengetedza Professional Committee yeChina Energy Research Association, parizvino, iyo pumped yekuchengetedza hydropower station ine yakakura kwazvo kukura uye yakakura yakaiswa simba pasi rose ndiyo pumped storage hydropower station. Pakazosvika 2019, simba rekuchengetedza simba repasi rose rasvika 180 miriyoni KW, uye huwandu hwakaiswa hwepombi yekuchengetera hydropower zviteshi zvapfuura 170 miriyoni KW, inoverengera makumi mapfumbamwe nemana muzana epasi rose rekuchengetedza simba.
Pombi yekuchengetera hydropower station inoshandisa simba pane yakaderera mutoro wesimba remagetsi kupomba mvura kunzvimbo yakakwirira yekuchengetera, uye kuburitsa mvura yekugadzira magetsi panguva yekuremerwa kwepamusoro. Kana mutoro wacho wakaderera, iyo pumped storage hydropower station ndiye mushandisi; Pamutoro wepamusoro, inzvimbo yemagetsi.
Iyo unit yePumped Storage Hydropower Station ine maviri akakosha mabasa: kupomba uye kugadzira magetsi. Iyo unit inoshanda se hydraulic turbine panguva yekuremerwa kweiyo simba system. Kuvhurwa kwegiyadhi vane ye hydraulic turbine inogadziriswa kuburikidza negavhuna system kushandura simba rinogona kuita remvura mumagetsi emagetsi ekutenderera kweyuniti, uye ipapo simba remagetsi rinoshandurwa kuita simba remagetsi kuburikidza nejenareta;
Kana mutoro wesimba remagetsi wakaderera, unoshandiswa sepombi yemvura kushanda. Simba remagetsi panzvimbo yakaderera rinoshandiswa kupomba mvura kubva kudhamu rezasi kuenda kudhamu repamusoro. Kuburikidza nekugadzirisa otomatiki kwegavhuna system, kuvhurwa kwegiya vane inongogadziriswa zvinoenderana nemusoro wepombi, uye simba remagetsi rinoshandurwa kuita simba remvura rekuchengetedza.
Pumped storage hydropower station inonyanya kuita basa rekuveura ndebvu, frequency modulation, emergency standby uye dema kutanga kwesimba remagetsi, iro rinogona kuvandudza uye kuenzanisa mutoro wesimba remagetsi, kuvandudza kunaka kwemagetsi uye mabhenefiti ehupfumi hwesimba remagetsi, uye ndiyo mbiru yekuve nechokwadi chekuchengetedza, hupfumi uye kugadzikana kushanda kwegidhi remagetsi. Pumped storage hydropower station inozivikanwa se "stabilizer", "regulator" uye "balancer" mukushanda kwakachengeteka kwegidhi remagetsi.
Maitiro ekusimudzira emapombi ekuchengetera hydropower zviteshi pasi rose musoro wakakwira, hukuru hukuru uye kumhanya kwakanyanya. Musoro wemvura wakakwirira zvinoreva kuti chikwata chiri kukura kusvika kumusoro wemvura. Kugona kukuru kunoreva kuti huwandu hwechikamu chimwe chete huri kuwedzera. Kumhanya kwepamusoro kunoreva kuti chikwata chinotora kumhanya kwakanyanya.
Chimiro uye maitiro
Zvivakwa zvikuru zvePumped Storage Hydropower Station zvinowanzo sanganisira repamusoro reservoir, rezasi reservoir, mvura yekufambisa system, powerhouse nezvimwe zvivakwa zvakakosha. Kuenzaniswa neyakajairwa hydropower zviteshi, iyo hydraulic zvimiro zvepombi yekuchengetedza hydropower zviteshi zvine anotevera hunhu:
Pane matura maviri. Zvichifananidzwa neyakajairwa hydropower zviteshi zvine simba rakafanana rakaiswa, reservoir kugona kwepombi yekuchengetedza hydropower zviteshi kazhinji idiki.
Mvura yakadzika yemvura inoshanduka zvikuru uye inokwira uye inodonha kakawanda. Kuti uite basa rekuveura ndebvu uye kuzadza mupata mugedhi remagetsi, kusiyanisa kwezuva nezuva kwemvura yekuchengetera mvura yePumped Storage Hydropower Station inowanzokura, kazhinji inodarika gumi ~ 20m, uye dzimwe nhepfenyuro dzemagetsi dzinosvika 30 ~ 40m, uye chiyero chekusiyana kwemvura yekuchengetera mvura inokurumidza, 5h ~ 1m kana 8m kana 8m kusvika 8h ~ 1m kana 8m kana 8m. / h.
Zvinodiwa zve anti-seepage ye reservoir zvakakwirira. Kana iyo yakachena pombi yekuchengetedza hydropower station yakarasa mvura yakawanda nekuda kwekudonha kwedhamu repamusoro, kugadzirwa kwemagetsi kwechiteshi chemagetsi kunoderedzwa. Nokudaro, zvinodiwa zve-anti-seepage ye-reservoir zvakakwirira. Panguva imwecheteyo, kuitira kudzivirira kuparara kwemamiriro ezvinhu e-hydrogeological munzvimbo yeprojekti, kukuvara kwesepage uye kunyura kwakadzika kunokonzerwa nekuputika kwemvura, zvinodiwa zvepamusoro zvinoiswawo pamberi pekudzivirira kudonha kwedhamu.
Musoro wemvura wakakwirira. Musoro wemvura wePumped Storage Hydropower Station kazhinji wakakwira, kazhinji 200 ~ 800m. Jixi Pumped Storage Hydropower Station ine hurefu hwakaiswa hunosvika 1.8 miriyoni kW ndiyo yekutanga 650 metres head section project muChina, uye Dunhua Pumped Storage Hydropower Station ine hurefu hwakaiswa hunosvika 1.4 miriyoni kW ndiyo yekutanga 700 metres head section project muChina. Nekuenderera mberi kwekusimudzirwa kwehunyanzvi hwenzvimbo yepombi yekuchengetedza hydropower zviteshi, huwandu hwemusoro wepamusoro uye hukuru hwemagetsi emagetsi emagetsi muChina huchawedzera.
Kukwirira kwekuiswa kwechikwata kwakaderera. Kuti ukunde pesvedzero ye buoyancy uye seepage pane Powerhouse, hombe pombi yekuchengetedza hydropower zviteshi zvakavakwa kumba nekune dzimwe nyika zvinonyanya kutora chimiro chepasi pevhu magetsi mumakore achangopfuura.
