Ngomhlaka-15 Septhemba, umcimbi wokuqala wokulungiselela iphrojekthi yeSiteshi Sikagesi Esinompompi saseZhejiang Jiande esinomthamo ofakiwe ongama-kilowatts ayizigidi ezingu-2.4 wabanjwa eMeicheng Town, eJiande City, eHangzhou, okuyisiteshi sikagesi esikhulu kunazo zonke esinompompi esakhiwayo eMpumalanga yeShayina. Ezinyangeni ezintathu ezedlule, wonke amayunithi ayisithupha eSiteshi Sikagesi Esinompompi saseChanglongshan esinomthamo ofakiwe ongama-kilowatts ayizigidi ezingu-2.1 asanda kuqaliswa ukusebenza e-Anji County, eHuzhou City, eqhele ngamakhilomitha angu-170.
Njengamanje, iSifundazwe saseZhejiang sinenani elikhulu kakhulu lamaphrojekthi okugcina izinto ezipompiwe eShayina. Kuneziteshi zamandla zokugcina izinto ezipompiwe ezi-5 ezisebenzayo, amaphrojekthi ayi-7 asakhiwa, kanye namaphrojekthi angaphezu kwama-20 esigabeni sokuhlela, ukukhethwa kwendawo kanye nokwakhiwa.
“IZhejiang iyisifundazwe esinemithombo yamandla emincane, kodwa futhi iyisifundazwe esisebenzisa kakhulu amandla. Ibilokhu ingaphansi kwengcindezi enkulu ukuqinisekisa ukuphepha kwamandla kanye nokutholakala kwawo. Eminyakeni yamuva nje, ngaphansi kwesizinda 'se-dual carbon', kuyaphuthuma ukwakha uhlelo olusha lwamandla olunesilinganiso esikhula kancane kancane samandla amasha, okubeka ingcindezi enkulu ekushefweni okuphezulu. Iziteshi zamandla zokugcina ezipompiwe ezakhiwe, ezakhiwayo futhi ezihleliwe eZhejiang zingadlala indima ebalulekile ekushefweni okuphezulu, ukugcwaliswa kwesigodi, ukuguqulwa kwamava, njll. kumagridi kagesi aseZhejiang ngisho naseMpumalanga China, futhi zingadlala indima emandleni omoya, amandla omoya Ukukhiqizwa kwamandla e-photovoltaic kanye neminye imithombo yamandla emisha kuhlanganiswe ukuze kufezwe ukuhambisana kwamandla amaningi futhi kuguqulwe 'ugesi kadoti' ube 'ugesi osezingeni eliphezulu'. ” NgoSepthemba 23, uHan Gang, unjiniyela we-Energy and Environment Research Institute of Zhejiang Development Planning Research Institute, utshele izindaba ezikhulayo.
Ibhizinisi elingabizi kakhulu "likagesi wama-kilowatt angu-4 ngehora likagesi wama-kilowatt angu-3"
Amandla akhiqizwa futhi asetshenziswe ngokushesha, futhi awakwazi ukugcinwa kugridi yamandla. Esikhathini esidlule, ohlelweni lwegridi yamandla olulawulwa amandla okushisa kanye nokukhiqizwa kwamandla kagesi ngamanzi, indlela yendabuko ukwakha njalo izikhungo zokukhiqizwa kwamandla ukuze kuhlangatshezwane nezidingo zokukhula komthwalo wamandla, nokuvala inani elikhulu lamayunithi ejeneretha lapho ukusetshenziswa kwamandla kuphansi ukuze kongiwe amandla. Ngakho-ke, kuzokwandisa nobunzima bokulawulwa kwamandla futhi kulethe izingozi ezifihliwe ekuzinzeni nasekuphepheni kwegridi yamandla.
Ngawo-1980, ngentuthuko esheshayo yezomnotho esifundeni saseYangtze River Delta, isidingo sikagesi sanda kakhulu. Kugridi yamandla yase-East China, ephethwe amandla okushisa, kwadingeka ukuthi idonse inkinobho ukuze inciphise amandla lapho umthwalo uphezulu futhi inciphise ukuphuma kwamayunithi okukhiqiza amandla okushisa (amandla okukhipha ngaphakathi kwesikhathi seyunithi) lapho umthwalo uphansi. Kulesi simo, iGridi Yamandla yase-East China yanquma ukwakha isiteshi samandla okugcina esinomthamo omkhulu. Ochwepheshe baseshe izindawo ezingu-50 zeziteshi zamandla okugcina ezinompompi eZhejiang, eJiangsu nase-Anhui. Ngemva kokuhlaziya okuphindaphindiwe, ukubonisa nokuqhathanisa, indawo itholakala eTianhuangping, e-Anji, eHuzhou ukuze kwakhiwe isiteshi samandla okugcina esinompompi sokuqala e-East China.
Ngo-1986, amayunithi akhiqiza i-Tianhuangping Pumped Storage Power Station alungiswa yi-East China Survey and Design Institute kanti umbiko we-Feasibility Study Report we-Zhejiang Tianhuangping Pumped Storage Power Station waqedwa. Ngo-1992, kwaqalwa iphrojekthi ye-Tianhuangping Pumped Storage Power Station, futhi ukwakhiwa kwaqalwa ngokusemthethweni ngoMashi 1994. NgoDisemba 2000, wonke amayunithi ayisithupha aqaliswa ukusebenza ukuze kukhiqizwe ugesi, ngomthamo ofakiwe ongama-kilowatts ayizigidi ezingu-1.8. Isikhathi sonke sokwakha sathatha iminyaka eyisishiyagalombili. UJiang Feng, iPhini likaMphathi Jikelele we-East China Tianhuangping Pumped Storage Co., Ltd., usebenze eTianhuangping Pumped Storage Power Station iminyaka engama-27 kusukela ngo-1995. Wethula: “Isiteshi samandla sokugcina amanzi esinompompi sakhiwe kakhulu yithangi eliphezulu, ithangi eliphansi, ipayipi lokudlulisa kanye ne-turbine yephampu ephendukayo. Isiteshi samandla sokugcina amanzi esinompompi sihlose ukusebenzisa amandla asele esikhathini somthwalo ophansi wesistimu yamandla ukupompa amanzi kusuka ethangini eliphansi kuya ethangini eliphezulu ukugcina amandla asele, nokukhulula amanzi kusuka ethangini eliphezulu kuya ethangini eliphansi ukuze kukhiqizwe ugesi lapho ukusetshenziswa kwamandla okuphezulu noma uhlelo ludinga ukulawulwa okuguquguqukayo, ukuze kuhlinzekwe amandla aphezulu kanye nezinsizakalo ezisizayo zesistimu yamandla. Ngesikhathi esifanayo, iyunithi iyapompa futhi ikhiqiza Ngesikhathi senqubo yokukhiqiza ugesi, kungenziwa izinhlobo ezahlukene zokuguqulwa kwesimo somsebenzi, futhi izinsizakalo zokulungisa eziguquguqukayo zinganikezwa ngokwezidingo zesistimu ukuze kufezwe ukusebenza okuphephile nokuzinzile kwesistimu kanye nokusetshenziswa kahle kwezinsiza zamandla.”
"Enkambisweni yokuguqulwa kwamandla, kuzoba nengxenye ethile yokulahleka kwamandla. Izinga lokuguqulwa kokusebenza kahle kwamandla le-Tianhuangping Pumped Storage Power Station liphezulu cishe ngo-80% ngenxa yezimo zezwe kanye nezinye izizathu. Kodwa-ke, izinga lokuguqulwa lilonke leziteshi zamandla zokugcina ezikhutshiwe ezinkulu cishe lingama-75%, okulingana namahora ama-kilowatt angu-4 amahora ama-kilowatt angu-3. Kubonakala sengathi akubizi kakhulu, kodwa isitoreji esikhutshiwe empeleni ubuchwepheshe obuvuthiwe kakhulu, umnotho ongcono kakhulu, kanye nezimo zokuthuthukiswa okukhulu kakhulu kokuhlinzekwa kwamandla okuluhlaza, okunekhabhoni ephansi, okuhlanzekile nokuguquguqukayo." UJiang Feng utshele izindaba ezikhulayo.
Isiteshi Sikagesi Esinompompi saseTianhuangping siyisibonelo esivamile sokubambisana kwesifunda eMfuleni iYangtze. Ngenxa yokutshalwa kwezimali okukhulu ekwakhiweni kwesiteshi sikagesi, iShanghai, iSifundazwe saseJiangsu, iSifundazwe saseZhejiang kanye neSifundazwe sase-Anhui basayine iSivumelwano Sokuqoqa Imali Yokwakhiwa Kwesiteshi Sikagesi Esinompompi saseTianhuangping ukuze batshale imali ndawonye ekwakhiweni. Ngemva kokuba isiteshi sikagesi sesiqediwe futhi siqaliswe ukusebenza, ukubambisana kwezifundazwe kuye kwaqaliswa ngaso sonke isikhathi. Amagridi kagesi esifundazwe nawomasipala azothola amandla kagesi ngokwesilinganiso sokutshalwa kwezimali ngaleso sikhathi futhi ahlinzeke ngamandla kagesi ahambisanayo. Ngemva kokuqedwa nokusebenza kweSiteshi Sikagesi Esinompompi saseTianhuangping, sikhuthaze ngempumelelo ukusetshenziswa kwamandla amasha eMpumalanga China, sathuthukisa ukusebenza kohlelo lwegridi yamandla, futhi saqinisekisa ngokuthembekile ukuphepha kwegridi yamandla yaseMpumalanga China.
Isikhathi sokuthunyelwe: Novemba-09-2022
