Aikace-aikace da Halayen Babban Wutar Lantarki na USB

Daga hangen nesa na duniya, high-voltage DC watsa na USB ana amfani da shi zuwa wurare masu zuwa kamar watsawa mai tsayi mai tsayi, haɗin wutar lantarki, da kuma watsa kebul na jirgin ruwa mai nisa mai nisa tare da fa'ida a bayyane.

Na farko shine watsa layin sama mai nisa. Bisa ga sakamakon binciken da ya dace, Layin sama na DC watsa ya fara cin moriyarsa 10 biliyan watts kuma 300 kilomita ko fiye. Wannan yana nufin cewa fiye da 26% na jimlar ƙarfin watsawa na duniya ya shafi layukan kan DC.

Na biyu shine watsa kebul na karkashin ruwa. Nazarin ya nuna cewa kusan kashi ɗaya bisa uku na ayyukan watsawar DC na duniya na yanzu don watsa kebul na ƙarƙashin ruwa ne.

Na uku shine iyakance gajeriyar kewayawa. Tare da ƙasashe da yankuna suna ƙara ƙarfin wutar lantarki, samar da wutar lantarki da ginin grid na ci gaba da fadadawa, girman grid AC yana ƙara girma da girma, kuma kuskuren gajeriyar hanya yana faruwa yayin da ƙarancin wutar lantarki shima yana ƙara girma. Watsawar DC yana da fa'idodi masu fa'ida a cikin iyakancewa gajeriyar kewayawa halin yanzu kuma ana amfani dashi a wurare da yawa.

A matsayin ma'auni a kan magudanar ruwa na gajeren zango a cikin yankunan da ke da babban nauyi na birni, Kayan watsa wutar lantarki mai nauyi na DC tare da canjin lokaci na na'urar ana fifita su sosai saboda ƙaramin sawun sa da saurin amsawa.

A cikin yankin haɗin gwiwar grid, Yin amfani da hanyoyin DC kamar BTB don haɗa haɗin ƙananan ƙananan ƙananan, Yin aiki da kananun tsare-tsare na iya yadda ya kamata ya rage kuskure gajerun igiyoyin ruwa. Nazarin da masanan Jafananci suka gudanar akan tsarin serial a Kansai, China, Kyushu, da Shikoku a Japan sun nuna cewa idan ana amfani da hanyoyin DC don haɗa Kansai zuwa China, China zuwa Kyushu, Kyushu to Shikoku, da Shikoku zuwa Kansai, Za a danne magudanan ruwa na ɗan gajeren lokaci sosai kuma za a iya aiwatar da watsawa daga ƙananan tsarin zuwa manyan tsarin.

Bugu da kari, Ana iya amfani da masu juyawa da suka ƙunshi na'urori masu sauyawa don samar da wutar lantarki ga ƙananan keɓaɓɓun tsarin kamar dandamalin mai da tsibirai.. Zuwa gaba, Hakanan za'a iya amfani da su a cikin tsarin rarraba wutar lantarki na birane don samun damar samun wutar lantarki da aka rarraba irin su man fetur da kuma samar da wutar lantarki na photovoltaic. A nauyi DC watsa tsarin ya fi taimakawa wajen magance matsalar kwanciyar hankali na samun makamashi mai tsafta.

A halin yanzu, akwai manyan ayyukan watsa wutar lantarki na DC a nahiyoyi biyar a duniya, kuma suna da yawa a yankuna masu ci gaban tattalin arziki kamar Arewacin Amurka da Yammacin Turai. Yayin da yankin ci gaban tattalin arziki ke tafiya zuwa Asiya, ana samun ƙarin ayyukan watsa wutar lantarki na DC a China da kewaye.

Binciken kasar Sin game da watsa wutar lantarki mai karfin wutar lantarki ya fara ne a cikin shekarun 1950, kuma farkon thyristor bawul na'urar kwaikwayo da aka gina a cikin 1960s a China Electric Power Research Institute. Domin ingantacciyar nazarin watsa wutar lantarki mai ƙarfi ta DC, an canza layin kebul na AC zuwa a 31 kV DC watsa gwajin layin a Shanghai a 1977.

Binciken da aka yi a baya ya kafa wani tushe don haɓaka ƙarfin wutar lantarki mai ƙarfi a China. Zuwa karshen shekarun 1980, Bincike da ci gaban watsa wutar lantarki na kasar Sin na DC ya yi nasara kuma ya fara haɓaka cikin sauri. Fiye da 10 An sanya ayyukan watsa DC a cikin aiki. Musamman, a watan Disamba 28, 2009, An yi nasarar aiwatar da aikin watsa wutar lantarki na UHV DC na Yunnan-Guangdong akan igiya guda, wanda shine farkon ± 800 kV UHV DC watsa aikin watsawa a duniya. Wannan shine farkon ± 800 kV UHV aikin watsawa a duniya. Hakan ya nuna cewa fasahar samar da wutar lantarki da kera kayan aikin kasar Sin sun kai matakin ci gaba na kasa da kasa, kuma sun mamaye wani sabon matsayi a fannin watsa wutar lantarki da sauyi a duniya..

In order to realize China’s “west-east power transmission” strategic plan, Kasar Sin tana haɓaka aikin gina ± 660 KV, ± 800 KV, kuma ± 1000 kV ultra-high-voltage DC watsa ayyukan.

Tare da saurin haɓaka sabbin makamashi da buƙatun kare muhalli, Kasar Sin tana da karfin bukatar kasuwa don fasahar watsa labarai ta DC.

A gaba 20 shekaru, Jiha Grid Corporation na shirin gina fiye da 40 Ayyukan watsawa na DC, ciki har da fiye da 15 UHV DC ayyukan watsawa.

A cewar cibiyoyin da abin ya shafa, bisa ga farashin kayan aiki na yanzu, Jimillar jarin da aka yi na gina kowane aikin watsa UHV DC a kasar Sin ya zarce haka 15 yuan tiriliyan. Tsakanin su, farashin UHV DC bawul da mai canzawa shine 1.5 biliyan ku 2 yuan tiriliyan, Farashin lebur reactor na lebur ya kusa 1 yuan tiriliyan, farashin tsarin sarrafawa da kariya ya fi 400 yuan miliyan, da jimlar farashin filin AC da filin DC cikakke kayan aiki shima yana kusa 2 yuan tiriliyan. Zuba jarin kayan aiki (ban da layi da hasumiyai) ga kowane tashar watsa watsawar UHV DC yana kusa 8 yuan tiriliyan. Ana sa ran kayan watsawa na DC zasu kai girman kasuwa kusan 200 yuan biliyan a gaba 20 shekaru.

Ci gaban fasaha yana haifar da haifar da ƙarin sabbin kayayyaki da fasaha, kuma amfani da fasahar watsa wutar lantarki mai ƙarfi ta DC yana faɗaɗawa. Wasu sababbin hanyoyin samar da wutar lantarki suna buƙatar aikace-aikacen fasahar watsawa ta DC. Misali, wutar lantarki da ruwa mai maganadisu ke samarwa, iskar gas, Kwayoyin mai, kuma yakamata a aika da ƙwayoyin hasken rana a yanayin DC, da kuma tashoshin makamashin teku da ke cikin tekuna masu nisa suna buƙatar amfani da su igiyoyin submarine DC don aika wutar lantarki zuwa babban yankin. Bugu da kari, sababbin batura da na'urori masu sarrafawa da sauran sabbin tsarin ajiyar makamashi, kuma ana buƙatar haɗin tsarin wutar lantarki na AC lokacin da fasahar watsa DC.

Yana yiwuwa tare da ƙarin haɓaka na'urorin lantarki masu ƙarfi, sabunta fasahar kwamfuta, bayyanar sabbin kayan don watsa wutar lantarki da canji, da haɓakawa da amfani da sabbin makamashi da sabuntawa, babban ƙarfin wutar lantarki na DC watsawa zai sami fa'idar aikace-aikacen haƙiƙa.
