Ukadaulo watsopano wofewa wowongoka komanso kugwiritsa ntchito kwake muzinthu zotsekemera

Kuyambira m'chaka cha 1966, EM Technology yakhala ikudzipereka kuti ifufuze ndi kupanga zipangizo zotetezera. Zaka 56 kulima mu makampani, dongosolo lalikulu la kafukufuku wa sayansi wapangidwa, mitundu yoposa 30 ya zipangizo zatsopano kutchinjiriza apangidwa, kutumikira mphamvu ya magetsi, makina, mafuta, mankhwala, zamagetsi, magalimoto, zomangamanga, mphamvu zatsopano ndi mafakitale ena. Pakati pawo, ntchitoKuyika kwazinthu zamakina pamakina omangira ndi njira imodzi yofunika kwambiri yomwe timayang'ana kwambiri.

Monga m'badwo watsopano waukadaulo wotumizira ma DC, kufalikira kwa DC kosinthika kuli kofanana ndi kufalikira kwa HVDC mu kapangidwe kake, komwe kumapangidwabe ndi masiteshoni osinthira ndi mizere ya DC. Mosiyana ndi magwero apano amtundu wa HVDC kutengera kutengera ukadaulo woyendetsedwa ndi gawo, chosinthira mu flexible DC transmission ndi voltage source converter (VSC), chomwe chimadziwika ndi kugwiritsa ntchito zida zosinthira (nthawi zambiri IGBT) komanso ukadaulo wapamwamba kwambiri wosinthira. M'zaka zaposachedwa, ma flexible DC transmission akupita ku giredi yapamwamba yamagetsi ndi mphamvu.

Mkhalidwe wa ntchito wa IGBT: IGBT yodzaza ndi insulated chipata cha bipolar chubu, yomwe imatha kuzimitsidwa, ili ndi ubwino wotayika pang'ono ndi kuwongolera kosavuta, ndipo imatha kuonedwa ngati CPU ya kufala kwachindunji kofewa. Pakalipano, IGBT yomwe imagwiritsidwa ntchito ku polojekitiyi ndizinthu zonse zomwe zimatumizidwa kunja, makamaka ABB ndi Siemens, pamene IGBT yapakhomo yokhala ndi magetsi apamwamba komanso mphamvu zambiri ilibe zinthu zokhwima. Pakalipano, kupita patsogolo kwa malo akuchedwa, kudalira kuchokera kunja kuli kolimba, ndipo chiopsezo ndi chachikulu. Panthawi imodzimodziyo, mtengo wa IGBT umakhala pafupifupi 30% ya mtengo wa valve.

Kutheka kwa IGCT yatsopano: Poona kutsika kwa IGBT ku China, timayesa kusintha IGBT ndi IGCT. Kusinthasintha kwafupipafupi, mphamvu yoyendetsa galimoto ndi machitidwe ena a IGCT achikhalidwe ndi otsika kwa IGBT, koma ali ndi ubwino wina mu mphamvu, kutayika kwa boma, kutayika kwa kusintha ndi mtengo (mtengo wa mankhwala omwe ali ndi mphamvu yofanana ndi pafupifupi 1/2 ya IGBT). Komabe, ngati IGCT yachikhalidwe ikugwiritsidwa ntchito ku UHV flexible power transmission, IGCT ikayatsidwa, diode idzatulutsa mphamvu yaikulu yobwezeretsanso, zomwe zidzakhudza kwambiri dongosolo. Choncho, pofuna kuteteza diode, tinafufuza ICCT yatsopano powonjezera mabwalo owonjezera a mayamwidwe pamtundu wa IGCT wachikhalidwe kuti achepetse zotsatira za dongosolo.

Mapulogalamu Atsopano a IGCT: Powonjezera mabwalo owonjezera owonjezera, kapangidwe kathu katsopano ka IGCT kamakhala kocheperako komanso kamakhala kolimba kwambiri komanso kudalirika kwambiri, kotero titha kupanga zida zotchinjiriza zodalirika kwambiri komanso mphamvu zamakina. Xd Power System Co., Ltd. ikuunikiratu zida zotchingira za mayamwidwe a IGCT a projekiti ya Yunnan Maitrei. Ngati mapangidwewo amachokera ku dongosolo la XD Power system, chiwerengero cha ma modules a IGCT chidzachepetsedwa pafupifupi 3% poyerekeza ndi IGBT, ndipo kuchuluka kwa zipangizo zotetezera kudzakhala 2-3 nthawi ya IGBT.
