Wopereka Chitetezo cha Zachilengedwe Padziko Lonse

Ukadaulo watsopano wowongoka wofewa komanso momwe umagwiritsidwira ntchito pazinthu zotenthetsera

Kuyambira mu 1966, EM Technology yakhala ikudzipereka pakufufuza ndi kupanga zinthu zotetezera kutentha. Kwa zaka 56 ikukula mumakampaniwa, njira yayikulu yofufuzira yasayansi yapangidwa, mitundu yoposa 30 ya zinthu zatsopano zotetezera kutentha yapangidwa, zomwe zimagwiritsa ntchito magetsi, makina, mafuta, mankhwala, zamagetsi, magalimoto, zomangamanga, mphamvu zatsopano ndi mafakitale ena. Pakati pawo, kugwiritsa ntchitoKuteteza zinthu zomangira makina opangira zinthu ndi chimodzi mwa zinthu zofunika kwambiri zomwe tikuyang'ana kwambiri.

Monga mbadwo watsopano wa ukadaulo wotumizira ma DC, kutumiza kwa DC kosinthasintha kumafanana ndi kutumiza kwa HVDC mu kapangidwe kake, komwe kumapangidwabe ndi malo osinthira ndi mizere yotumizira ma DC. Mosiyana ndi kutumiza kwa HVDC komwe kumachokera ku gwero lamakono kutengera ukadaulo wosinthira wolamulidwa ndi gawo, chosinthira mu kutumiza kwa DC kosinthasintha ndi chosinthira ma voltage source (VSC), chomwe chimadziwika ndi kugwiritsa ntchito zida zosinthika (nthawi zambiri IGBT) ndi ukadaulo wosinthira ma frequency apamwamba. M'zaka zaposachedwa, kutumiza kwa DC kosinthasintha kukukula kupita ku kalasi yapamwamba yamagetsi ndi mphamvu.

Momwe IGBT imagwirira ntchito: IGBT ili ndi chubu chotenthetsera cha bipolar chomwe chimatha kuzimitsidwa, chili ndi ubwino wotayika pang'ono komanso kulamulira kosavuta, ndipo chingathe kuonedwa ngati CPU ya transmission yofewa mwachindunji. Pakadali pano, IGBT yomwe imagwiritsidwa ntchito pa ntchitoyi ndi zinthu zonse zotumizidwa kunja, makamaka ABB ndi Siemens, pomwe IGBT yapakhomo yokhala ndi magetsi ambiri komanso mphamvu yayikulu ilibe zinthu zokhwima. Pakadali pano, kupita patsogolo kwa malo kuli pang'onopang'ono, kudalira kutumiza kunja kuli kolimba, ndipo chiopsezo chake ndi chachikulu. Nthawi yomweyo, mtengo wa IGBT umakhala pafupifupi 30% ya mtengo wa valavu.

Kuthekera kwa IGCT yatsopano: Poganizira kuti IGBT ndi yotsika kwambiri ku China, tikuyesera kusintha IGBT ndi IGCT. Kusinthasintha kwa ma switching, mphamvu yoyendetsera ndi magwiridwe ena a IGCT yachikhalidwe ndi otsika poyerekeza ndi IGBT, koma ili ndi ubwino wina pa mphamvu, kutayika kwa nthawi yomwe ikugwiritsidwa ntchito, kutayika kwa ma switching ndi mtengo (mtengo wa zinthu zomwe zili ndi mphamvu yomweyo ndi pafupifupi 1/2 ya IGBT). Komabe, ngati IGCT yachikhalidwe ikugwiritsidwa ntchito pa UHV flexible power transmission, IGCT ikayatsidwa, diode ipanga mphamvu yayikulu yobwezeretsa mphamvu, yomwe idzakhala ndi mphamvu yayikulu pamakina. Chifukwa chake, kuti titeteze diode, tidafufuza ICCT yatsopano powonjezera ma absorption circuits owonjezera pa module yachikhalidwe ya IGCT kuti tichepetse kukhudzidwa kwa makinawo.

Mapulogalamu Atsopano a IGCT: Ndi kuwonjezera ma circuit owonjezera olowetsa madzi, kapangidwe kathu katsopano ka IGCT ndi kakang'ono kwambiri ndipo kali ndi mphamvu zambiri zotsutsana ndi kukhudzidwa komanso kodalirika kwambiri, kotero titha kupanga zipangizo zotetezera kutentha zomwe zimakhala zodalirika kwambiri komanso mphamvu zamakanika. Xd Power System Co., Ltd. ikufufuza pasadakhale zipangizo zotetezera kutentha za circuit yolowetsa madzi ya IGCT ya pulojekiti ya Yunnan Maitrei. Ngati kapangidwe kake kakuchokera pa dongosolo la XD Power, chiwerengero cha ma module a IGCT chidzachepetsedwa ndi pafupifupi 3% poyerekeza ndi IGBT, ndipo kuchuluka kwa zipangizo zotetezera kutentha kudzakhala kuwirikiza kawiri kapena katatu kuposa IGBT.
