I-15 GWh kagesi oluhlaza osuka e-Gansu usanda kudluliselwa eZhejiang.
'Lokhu kungumsebenzi wokuqala ka-Gansu wamandla aluhlaza awela izifundazwe kanye nasezifundeni,' kusho u-He Xiqing, uMqondisi Omkhulu we-Gansu Electric Power Trading Company.Ngemva kokuba umsebenzi usuqediwe endaweni yokuhweba nge-elekthronikhi ye-Beijing Power Exchange Center, amandla aluhlaza e-Gansu aqonda ngqo e-Zhejiang ngolayini wokudlulisa we-Ningdong-Shaoxing ±800kV UHVDC.
Ecebile ngezinsiza zomoya nelanga, amandla anamandla omoya namandla elanga e-Gansu angama-560 GW kanye ne-9,500 GW ngokulandelanayo.Kuze kube manje, umthamo ofakiwe wamandla amasha uthatha cishe isigamu sawo wonke, futhi izinga lokusebenzisa ugesi ovela emandleni amasha likhuphuke lisuka ku-60.2% ngo-2016 laya ku-96.83% namuhla.Ngo-2021, ukukhiqizwa kwamandla amasha eGansu kweqe ama-TWh angama-40 kanti ukukhishwa kwe-carbon dioxide kwehliswa cishe ngamathani ayizigidi ezingama-40.
Ukudluliswa kukagesi obheke empumalanga osuka eGansu kuzoba phezulu ku-100 TWh ngonyaka
Phansi kwezintaba ze-Qilian amakhilomitha angaphezu kuka-60 enyakatho yedolobha laseZhangye, esifundazweni saseGansu, izinjini zomoya zizungeza nomoya.Lena indawo ka-Pingshanhu Wind Farm.'Wonke ama-turbines omoya afakwe izinzwa zokuqondisa umoya futhi 'azolandela umoya' ngokuzenzakalelayo', kusho uZhang Guangtai, inhloko yepulazi lomoya, 'ipulazi likhiqiza i-1.50 MWh kagesi ngehora elilodwa.'
Ogwadule lwaseGobi eDolobheni laseJinchang, amaphaneli e-photovoltaic aluhlaza ahlelwe ngendlela ehlelekile.Kufakwe isistimu yokulandelela ukuze amaphaneli akwazi ukushintsha i-engeli ngaselanga, nokuqinisekisa ukuthi ilanga likhanya ngokuqondile kumaphaneli e-photovoltaic.Inyuse isizukulwane ngo-20% kuya ku-30%.
'Imboni yamandla ahlanzekile ingaphansi kwentuthuko esheshayo futhi enkulu,' kusho u-Ye Jun, uSihlalo we-State Grid Gansu Electric Power.'Ngokwakha izintambo zikagesi ze-UHV eziphumela ngaphandle, ugesi osele ulethwa eChina emaphakathi nasempumalanga.'
NgoJuni 2017, i-Gansu yaqeda futhi yaqala ukusebenza i-Jiuquan-Hunan ±800kV UHVDC Transmission Project, intambo yokuqala kagesi okuhloswe ngayo ukudlulisa amandla amasha e-China.ESiteshini se-Qilian Converter, isiphetho sokudlulisa, ugesi oluhlaza osuka e-Hexi Corridor uyanyuswa ube ngu-800 kV bese udluliselwa ngqo e-Hunan.Kuze kube manje, i-Qilian Converter Station isidlulisele isamba esingu-94.8 TWh kagesi e-Central China, okulinganiselwa ku-50% kagesi ophuma ngaphandle ophuma kugridi yamandla kagesi e-Gansu, kusho uLi Ningrui, iPhini Likamongameli Omkhulu we-EHV Company of State. IGrid Gansu Electric Power kanye nenhloko yesiteshi sokuguqula i-Qilian.
'Ngo-2022, sizosebenzisa ngokugcwele uhlelo lokusebenza lwe-State Grid ngezinjongo zesimo sezulu saseShayina futhi sikhuthaze ngamandla ukwakhiwa kohlelo olusha lokuphakelwa kwamandla nokusetshenziswa okusekelwe emigqeni yokudlulisa i-UHV,' kusho u-Ye Jun. Ngemizamo ehlanganyelwe yeziphathimandla zikahulumeni namabhizinisi, ' i-Gansu-Shandong UHVDC Transmission Project isesigabeni sokuqala sokuvunywa manje.Ngaphezu kwalokho, uGansu usayine izivumelwano zokubambisana kwamandla kagesi neZhejiang neShanghai, kanye namaphrojekthi wokuhambisa i-Gansu-Shanghai kanye neGansu-Zhejiang UHV nawo ayathuthukiswa.'Kulindeleke ukuthi ekupheleni koHlelo Lweminyaka Eyi-14 Lweminyaka Emihlanu, ugesi ophuma minyaka yonke ophuma e-Gansu uzodlula u-100 TWh,' kwengeza u-Ye Jun.
Khulisa ukusetshenziswa kwamandla ahlanzekile ngokuthumela okuhlanganisiwe
E-Gansu Dispatching Center, yonke idatha yokukhiqiza amandla iboniswa ngesikhathi sangempela esikrinini.'Ngohlelo olusha lokulawula iqoqo lokuphehla amandla, inani eliphelele lokuphehlwa kanye nokuphumayo kwesikhungo ngasinye samandla kungalawulwa ngobuhlakani,' kusho u-Yang Chunxiang, isekela lomqondisi we-Dispatching Center of State Grid Gansu Electric Power.
Isibikezelo samandla omoya namandla elanga sibalulekile ekulawuleni okuhlakaniphile.'Isibikezelo samandla amasha siyindlela yezobuchwepheshe ebalulekile yokuqinisekisa ukusebenza okuphephile nokuzinzile kwezinhlelo zamandla kanye nokusetshenziswa kahle kwamandla amasha,' kusho uZheng Wei, Isazi Esiyinhloko Sokuphathwa Kokuthembeka e-State Grid Gansu Electric Power Research Institute.Ngokusekelwe emiphumeleni ebikezelwe, isikhungo esithumelayo singalinganisa isidingo sikagesi nokuphakelwa kwayo yonke igridi futhi sithuthukise uhlelo lokusebenza lwamayunithi akhiqizayo ukuze kubekelwe indawo futhi kuthuthukiswe ukusetshenziswa kwamandla amasha okukhiqiza amandla.
Eminyakeni yakamuva, i-Gansu yakhe inethiwekhi enkulu kunazo zonke emhlabeni ehlangene yokuqapha izinsiza zomoya kanye nelanga elakhiwe imibhoshongo yokulinganisa umoya yesikhathi sangempela engu-44, iziteshi eziyi-18 ezizenzakalelayo ze-meteorological photometric, kanye neziqaphi eziyi-10 zehaze nezintuli njll. 'Idatha yezinsiza zawo wonke amapulazi omoya. kanye nezitshalo zamandla e-photovoltaic ngaphakathi kwe-Hexi Corridor zingabhekwa ngesikhathi sangempela,' kusho uZheng Wei.Ukuze kuthuthukiswe ukunemba kokubikezela kwamandla omoya namandla elanga, Igridi Yesifunda yenze ucwaningo lobuchwepheshe olufana nokubikezela kweleveli ye-photovoltaic yezinga le-ultra-short-term.'Ukuphehlwa kwamandla amasha kwaminyaka yonke okubikezelwe ekuqaleni kuka-2021 bekungama-43.2 TWh ngenkathi u-43.8 TWh eqediwe, okuzuze ukunemba okucishe kube ngu-99%.'
Ngasikhathi sinye, imithombo yamandla yokulawulwa okuphezulu okufana nesitoreji esimpontshwa, indawo yokugcina amandla amakhemikhali, namandla ashisayo okusekela ukuthuthukiswa kwamandla amasha nakho kuyakhiwa.'I-Yumen Changma Pumped Storage Power Plant ifakiwe ohlelweni lukazwelonke lwamaphakathi nesikhathi eside lokugcinwa kwephampu, kanti isikhungo esisodwa esikhulu kunazo zonke sokugcina amandla kagesi we-electrochemical emhlabeni sakhiwe futhi saqala ukusebenza eGansu,' kusho uYang Chunxiang. .'Ngokuhlanganisa isitoreji samandla kanye nezitshalo zamandla amasha zibe izimboni zamandla ezingokoqobo zokulawulwa okuphezulu, umthamo wokulawula ophezulu wesistimu yegridi yamandla ungathuthukiswa ngokwengeziwe ukuze kuthuthukiswe ukuzinza nokuthembeka kwamandla amasha.'
Uhlelo olusekela izimboni luthola okwengeziwe emithonjeni yomoya kanye nelanga
Epaki yezimboni yokukhiqiza imishini yamandla emisha eWuwei, isethi yama-wind turbine blades angaphezu kwamamitha angu-80 ubude ayalayishwa ukuze alethwe e-Zhangye ebangeni elingaphezu kwamakhilomitha angu-200.
'Isizukulwane sinyusiwe sisuka ku-2 MW sangempela saya ku-6 MW ngalesethi yezinsimbi,' kusho u-Han Xudong, uMqondisi Wezokuphatha Jikelele e-Gansu Chongtong Chengfei New Materials Co., Ltd. Ezinkampanini eziphehla ugesi, lokhu kusho ukuthi amandla engeziwe ekhiqizwa ngenani eliphansi.'Namuhla, ama-wind turbine blades akhiqizwa eWuwei asedayiselwe izifundazwe eziningi.Ngo-2021, ama-oda amasethi angu-1,200 alethwa anenani eliphelele le-CNY750 million.'
Kuzuzisa amabhizinisi futhi kwenyuse iholo labantu bendawo.'Ukwenziwa kwama-wind turbine blades kudinga abasebenzi abaningi, iqoqo lezinsimbi lidinga ukubambisana okuseduze kwabantu abangaphezu kuka-200,' kusho u-Han Xudong.Inikeze imisebenzi engaphezu kuka-900 kubantu abavela emadolobhaneni aseduze namadolobhana.Ngezinyanga ezi-3 zokuqeqeshwa, bangaqala ngomsebenzi futhi ngamunye wabo uhola u-CNY4,500 ngokwesilinganiso ngenyanga.
U-Li Yumei, isakhamuzi saseZhaizi Village, Idolobha laseFengle, esifundeni saseLiangzhou, eWuwei, ujoyine inkampani njengesisebenzi ngo-2015 ngenqubo yokuqala yokukhiqiza ama-blade.'Umsebenzi awunzima futhi wonke umuntu angaqala ngemva kokuqeqeshwa.Manje sengingathola imali engaphezu kuka-CNY5,000 ngenyanga.Uma unekhono ngokwengeziwe, ungazuza kakhulu.'
'Ngonyaka odlule, izakhamuzi zethu zakhokhelwa imali engaphezu kuka-CNY100,000 isiyonke ngokuphehla ugesi we-photovoltaic,' kusho u-Wang Shouxu, iphini lomqondisi wekomidi lezakhamuzi zaseHongguang Xincun Village, Liuba Town, Yongchang County, Jinchang.Enye imali etholwayo isetshenziselwa ukwakha nokunakekela imisebenzi yezenhlalakahle yomphakathi futhi enye isetshenziselwa ukukhokhela imisebenzi yezenhlalakahle.I-Yongchang County yafakwa ohlwini njengesifunda sokulinga ukukhangisa amandla e-photovoltaic asabalalisiwe esiFundazweni sase-Gansu ngo-Agasti 2021. Umthamo wokufakwa ohleliwe ngu-0.27 GW futhi abalimi abahlomulayo kulindeleke ukuthi bakhulise imali yabo engenayo ngo-CNY1,000 ngonyaka.
Ngokusho kweKomidi lesiFundazwe le-CPC Gansu, iGansu izogxila ekuthuthukisweni kwemboni yamandla ahlanzekile futhi isheshise ukwakhiwa kwesizinda samandla ahlanzekile i-Hexi Corridor ukuze imboni entsha yamandla izoba umshayeli oyinhloko kanye nensika yomnotho wendawo. .
