He hangarau hou, he ngāwari, he tika, me tōna whakamahinga i roto i te rauemi whakamahana
Mai i te tau 1966, kua whakapau kaha a EM Technology ki te rangahau me te whakawhanake i ngā rauemi whakamahana. E 56 tau te roa o te mahi i roto i te umanga, kua whakatūria he pūnaha rangahau pūtaiao nui, neke atu i te 30 ngā momo rauemi whakamahana hou kua whakawhanakehia, e mahi ana ki te hiko, te mīhini, te hinu, te matū, te hikohiko, ngā motuka, te hanga, te pūngao hou me ētahi atu ahumahi. I roto i ēnei, ko te tono.
Ko te whakamahi i ngā rauemi whakamahana i roto i ngā mīhini whakarewa tētahi o ngā huarahi matua e arotahi ana mātou.
Hei whakatupuranga hou o te hangarau tuku hiko DC, he rite te hanganga o te tuku hiko DC ngāwari ki te tuku hiko HVDC, he mea tito tonu i ngā teihana kaitahuri me ngā raina tuku hiko DC. He rerekē i te momo tuku hiko HVDC o nāianei e hangai ana ki te hangarau whakawhiti ā-wāhanga, ko te kaitahuri i roto i te tuku hiko DC ngāwari ko te kaitahuri pūtake ngaohiko (VSC), e tohuhia ana e te whakamahinga o ngā taputapu whakawhiti (te nuinga o te IGBT) me te hangarau whakarerekētanga auau-teitei. I ngā tau tata nei, kei te whanake haere te tuku hiko DC ngāwari ki te taumata ngaohiko me te kaha teitei ake.
Tūnga tono o te IGBT: Kei te IGBT ngā ngongo bipolar kuaha kua whakamahanatia, ka taea te whakaweto, he iti te mate me te ngāwari ki te whakahaere, ā, ka taea te kī ko te PTM o te tuku tika ngawari. I tēnei wā, ko ngā hua kawemai katoa o te IGBT e whakamahia ana ki te kaupapa, ko te nuinga ko ABB me Siemens, ko te IGBT ā-rohe he nui te ngaohiko me te kaha teitei kāore he hua kua pakeke. I tēnei wā, he puhoi te ahunga whakamua o te rohe, he kaha te whakawhirinaki ki ngā kawemai, ā, he nui te mōrearea. I te wa ano, ko te utu o te IGBT e pā ana ki te 30% o te utu takirere.
Te Whaihua o te IGCT Hou: I runga i te iti o te whaihua o te IGBT i Haina, ka ngana mātou ki te whakakapi i te IGBT ki te IGCT. He iti iho te auau whakawhiti, te mana taraiwa me ētahi atu mahi a te IGCT tuku iho i te IGBT, engari he painga anō tōna i roto i te kaha, te ngaronga ā-tūnga, te ngaronga whakawhiti me te utu (ko te utu o ngā hua he rite te kaha he tata ki te 1/2 o te IGBT). Heoi, ki te whakamahia te IGCT tuku iho ki te tuku hiko ngāwari UHV, ina tahurihia te IGCT, ka whakaputahia e te diode he iahiko whakaora whakamuri nui, ka nui te pānga ki te pūnaha. Nō reira, hei tiaki i te diode, i tirotirohia e mātou te ICCT hou mā te tāpiri i ētahi atu ara iahiko mimiti ki te kōwae IGCT tuku iho hei whakaiti i te pānga ki te pūnaha.
Ngā Whakamahinga IGCT Hou: Mā te tāpiri i ngā ara iahiko mimiti tāpiri, he iti ake te kiato o tā mātou hoahoa IGCT hou, ā, he nui ake te ātete pānga me te pono, nō reira ka taea e mātou te hanga rauemi whakamahana me te pono o te whakamahana me te kaha miihini. Kei te rangahau mua a Xd Power System Co., Ltd. i ngā rauemi whakamahana mō te ara iahiko mimiti IGCT mō te kaupapa Yunnan Maitrei. Mena kei runga te hoahoa i te kaupapa pūnaha XD Power, ka whakaitihia te maha o ngā kōwae IGCT mā te 3% ki te whakataurite ki te IGBT, ā, ko te tapeke o ngā rauemi whakamahana ka 2-3 ngā wā i te IGBT.
