Ao te nuinga mano Runga Ngaohiko Direct nāianei Transformer

High-ngaohiko tuku nāianei tika (HVDC) kua tae mai te ara roa mai i 1882 ka te tuatahi o tona momo kawea mana i Miesbach i Bavaria ki te whakaaturanga hiko i roto i Munich, 57 kiromita (km) atu, i te mere 1,400 V. Hakihea Mutunga, i mua noa i te ao iriti i roto i te tekau tau hou, hoatu Siemens Energy me tukutuku operator Korean Power Mātiti ki te mahi i te pou tuatahi o te hono tuku i waenganui i nga kawanatanga Chinese tonga o Yunnan ko Guangdong, he 1,418-km ultra-tiketike-ngaohiko nāianei hāngai (UHVDC) pūnaha. E aho e te kaha te tuku o 5 GW, a mahi ana e ia i te ngaohiko o 800 kilovolts (kV) - He lekooti ao. ka waiho hei Worlds te nuinga mano Runga Ngaohiko Direct nāianei Transformer.

Ka tuku i te aho Yunnan-Guangdong mana i tipu huringa Rapa i raro i hanga i roto i te tonga China ki tere tipu tonga pa ahumahi rite Shenzhen ko Guangzhou i te raorao awa Pearl o Guangdong Province. Kei te whakaritea te whakaaetanga o te pou tuarua me te tīmata-ake o te pūnaha 800-kV katoa mō te waenganui-2010. Siemens, ki hoa Hainamana, hangaia te pūnaha HVDC me ngā wāhanga matua tukua, whai wāhi 10 nui 800-kV me 600-kV transformers pūtahuri (Figure 5), whiriwhiringa DC, me ngā wāhanga DC 800-kV.

Record-whawhati: Siemens ki te homai tino kaha 800-kV HVDC hiko o te ao ki a Haina / Record-kaiwahi: Siemens ki te homai tino kaha hiko 800-kV HVDC ao ?? s ki Haina
hiko Supergrid. I roto i te tekau tau e toru i muri mai, mahere China ki te hanga e rave rahi tipu huringa Rapa i roto i tona rohe tonga, te wahi e kei rauemi huringa nui. Roto i te tikanga ki te tiki te mana i enei tipu ki tere tipu pa ahumahi rite Shenzhen me Guangzhou i tonga i te whenua o, China te hanga i te-tawhiti roa, ultra-tiketike-ngaohiko raina tuku nāianei tika e mahi i 800 kV-te rekoata o te ao. ka homai Siemens Energy te 10 800-transformers kV (whakaaturia i konei) ki taua kaupapa me te tekau transformers 600-kV e Haratua 2010.Courtesy: Siemens Energy

whiriwhiria China ki te whakaara i te ngaohiko DC o ona hononga roa-tawhiti HVDC hou ki 800 kV i mōrahi DC taumata ngaohiko o 500 kV ki 600 kV whakamahia tēnei wā te ao ki te pare iho parekura tuku i runga i tawhiti roa, a no te mea ko reira mārama he kōwhiringa ngawari te. Whakatairitea ki te whakamahi i te hangarau o nāianei tauutuutu tikanga, E iti rauata utu raina tuku no te hiahiatia tetahi anake bipole te. A, no te whakaritea ki ngā HVDC 500-kV, utu whānui o te pūnaha 800-kV hou i matapae ki te kia 25% raro. ta Siemens e tono kiritaki Chinese te otinga 800-kV, i te tonu i raro i te rangahau me te whanaketanga, ahakoa whakaekea te kaihanga taputapu Tiamana i te aho HVDC 630-kV.

Te whakanui ake i te whakatauranga ngaohiko i whakamahia i mua 500 kV ki 800 kanohi kV he 60% whakanui i - te ara ta'ehanotatau i roto i te taumata ngaohiko - a ehara i te mea ohie, ta Siemens. Whakawhanake i te hiko 800-kV UHVDC i te taumata nui no te auraa te reira ikuna'i te wero matua o te whakahaere ngā whakaritenga mātao waho, me te ā. I roto i te awhe UHV, riro te tahi mau āhuatanga mātao tino nonlinear. hei tauira, te tawhiti i roto i te rangi whakawātea hiahiatia i waenganui nga wahi Hv me te whenua e taea e āhua 4 m ki 5 m mō ngā pūnaha HVDC 500-kV. Hoki ngā pūnaha 800-kV, Heoi, te 60% hua i roto i te taumata ngaohiko auraa e tata tuaruatia te whakawātea rangi e tika ana.

Hei whakatutuki i tenei whakawātea, kua pai te huarahi tino tika i ki ake i te rahi o ngā wāhanga me te tawhiti i waenganui i ngā wāhanga kia rite ki te whakatutuki i te kaha mātao rawaka. Ko tenei e kua hua i roto i te hoahoa tino nui, me te taputapu i roto i maha taime e kore e taea ki te whakaputa i ngā waka ranei. Na te huarahi tīpakohia ko te waihanga anō taputapu matua katoa whai wāhi ki te taumata ngaohiko 800-kV ki te whakarite i tētahi toenga arotau i waenganui i nga mara hiko me ngā āhuatanga.

tautooraa Siemens 'utua atu. I tua transformers mo te aho Yunnan-Guandong, inaianei kua whakatakotoria ano te kamupene ki te kaipuke e rima transformers 800-kV mo te kaupapa 800-kV tuarua i waenganui i te huringa tipu Xiangjiaba, kei roto i te tonga o Haina, ki Shanghai, etahi 2,071 km atu. Ko aho - e ka pea hei te roa hononga mana tuku i roto i te ao, no te whakahaere i muri mai i tēnei tau, - ka tuku 6,400 MW o te kaha mo te rangatira State Mātiti Corp. o China.

kamupene Swiss ABB, i riro hoki te tikanga mo taua kaupapa (14 800-kV me 14 400-transformers kV converter), kauwhautia i roto i te Hānuere i whakahaere momoho reira te whakamātautau raina-tuwhera tuatahi mō te Pou 1 o te aho. I rite kōrero te whakamātautau e rua nga tau i muri i te fariiraa i te tikanga, me te tau i mua o te hōtaka.

Ki te ōrite ana koe tenei Worlds te nuinga mano Runga Ngaohiko Direct nāianei Transformer Tuhinga , Rite te reira A Faaite i te reira.
