Midziyo yemagetsi ine simba shoma ichave chinhu chikuru mumusika

(1) Kudiwa kutsva kwakakonzerwa nekushandiswa kukuru kwekuvaka grid rakangwara

Kuvakwa kwegrid rakangwara kuchaitwa muzvikamu zvitatu gore ra2020 risati rasvika. Chikamu chekutanga ndeche2009-2011, kunyanya chekutsvaga uye mapurojekiti ekuedza; chikamu chechipiri ndeche2011-2015, apo grid rakangwara richaitwa padanho guru; chikamu chechitatu ndeche2016-2020 kuti ribudirire uye rivandudzwe. Parizvino, State Grid Corporation yeChina iri kuwedzera kuumbwa kwezvinodiwa zvehunyanzvi zvinosvika mazana maviri zvegrid rakangwara reChina. Kuunzwa kwekuronga uye zvinodiwa kwakaunza kuvakwa kwegrid rakangwara murwendo urwu, izvo zvichaunza kudiwa kukuru kwezvinokanganisa magetsi zvepakati nepakakwirira.

(2) Kudyara mari mukugadzira zvinhu kunokurudzira kukura mune ramangwana

Kugadzira zvinhu inzvimbo inokosha inoshandiswa muindasitiri yemagetsi ine simba shoma, uye imwe yenzvimbo gumi dzeinjiniya dzekuchengetedza simba nekuderedza kusvibiswa kwemhepo. Nekuda kwekumanikidzwa kwezviratidzo zvekuchengetedza simba, indasitiri yekugadzira yekuChina icharamba ichida zvakanyanya kudzora kuchengetedza simba uye zvigadzirwa zvemagetsi zvine hungwaru zvinogovera simba.

(3) Simba remhepo, simba rezuva nemamwe masimba matsva zvinounza kudiwa kukuru kwema "low-voltage circuit breakers" epakati nepamusoro.

Mushure meMusangano weCopenhagen, kudyara mari musimba idzva kwave chinhu chinotariswa pasi rose. Simba idzva uye hupfumi husina kabhoni yakawanda zvave nzira huru dzeindasitiri yemidziyo yemagetsi. Kukura kwakasimba kwesimba idzva kuchagadzira kudiwa kukuru kwezvigadzirwa zvemagetsi zvine simba rakaderera uye zvakagadzikana zvepakati nepamusoro. Kudiwa kwezvikamu zvemagetsi zvine simba rakaderera kunotarisirwa kuwedzera zvakanyanya mukati memakore 3-5. Matekinoroji akati wandei akakosha akadai se inverter control system uye tekinoroji yakabatana negrid yesimba remhepo uye kugadzirwa kwesimba re photovoltaic zvinofanirwa kufambiswa. Iyi inzira zvakare yekuwedzera mune ramangwana indasitiri yemagetsi ine simba rakaderera.

Kubva pakupera kwezana remakore rechi20 kusvika pakutanga kwezana remakore rechi21, makambani makuru ekunze akaunza ACB neMCCB zvitsva zvakatevedzana, uye zvave zvichivandudzwa uye zvichiwedzerwa nguva dzose. Vakaita budiriro huru nekuvandudza zvinhu zvitsva maererano nekushanda kukuru kwehunyanzvi, chimiro chechigadzirwa, uye mashandisirwo matsva etekinoroji. Pakati pavo, Siemens yeGermany ndiyo inonyanya kuzivikanwa. Midziyo yayo yemagetsi ine voltage shoma inogona kutaurirana inogona kuumba sisitimu yakakura kwazvo yeindasitiri, sisitimu yekutarisa kugoverwa kwesimba uye sisitimu yekuzvigadzira otomatiki yekuvaka. Iyo MDU series circuit breaker yakagadzirwa neMitsubishi Corporation inogona zvakananga kuita network yekutarisa simba remagetsi. Sisitimu, sisitimu yekutarisa nemidziyo, nezvimwewo.

Midziyo yemagetsi ine simba shoma inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana muhupfumi hwenyika uye ine hukama hwakasimba nemamiriro ekudyara mari munharaunda yese. 21 Kutaura zvazviri, yaive nguva yekukura nekukurumidza kweindasitiri yemidziyo yemagetsi ine simba shoma muChina. Kukura kweindasitiri yemidziyo yemagetsi ine simba shoma munyika yangu kwakaramba kuri pa10%-15% mumakore achangopfuura. Kugona kwemusika kweindasitiri yemidziyo yemagetsi ine simba shoma kwakabatana zvakanyanya nekukura kweindasitiri yemagetsi, indasitiri, dzimba, uye nharembozha. Pamwe chete nekugadzirisa chimiro chekudiwa kwemidziyo yemagetsi ine simba shoma uye kudiwa kunogona kuitwa nemusika wepasi rose, zvinopa nzvimbo yakakura yekuvandudzwa mune ramangwana kweindasitiri yemidziyo yemagetsi ine simba shoma.

Munguva yeChirongwa cheMakore Mashanu cheGumi nembiri, nekufambira mberi kwekuvakwa kwegrid yakangwara uye kuvandudzwa kuri kuitwa tekinoroji yekugadzira magetsi ane simba shoma, chizvarwa chitsva chemidziyo yemagetsi ine simba shoma ine hungwaru, modularity, uye kugona kutaurirana zvichave zvigadzirwa zvikuru mumusika. Zvigadzirwa zvechizvarwa chekutanga zvichabuda mumusika muna 2010, zvigadzirwa zvechizvarwa chechipiri zvichave zvigadzirwa zvemhando yepamusoro, uye zvigadzirwa zvechizvarwa chechitatu nezvimwe zvigadzirwa zvechizvarwa chechipiri zvichave zvigadzirwa zvepakati nepakati. Kubva muna 2021 kusvika 2025, grid yakangwara ichapinda padanho rakazara rekuvaka muzvikamu zvinomwe zvinosanganisira kutumira simba, kushandura, kugovera, uye kutaurirana.
