Alaab-qeybiyaha Caalamiga ah ee Ilaalinta Deegaanka

Tiknoolajiyad cusub oo jilicsan oo toosan iyo codsigeeda ku saabsan walxaha dahaarka

Tan iyo 1966, EM Technology waxay ka go'an tahay cilmi-baarista iyo horumarinta agabka dahaarka. 56 sano oo beerista warshadaha ah, nidaam cilmi-baaris oo weyn ayaa la sameeyay, in ka badan 30 nooc oo agab dahaar cusub ah ayaa la sameeyay, kuwaas oo u adeega korontada, mishiinnada, batroolka, kiimikada, elektaroonigga, baabuurta, dhismaha, tamarta cusub iyo warshadaha kale. Kuwaas waxaa ka mid ah codsiga.qalabka dahaarka ee mashiinnada wax lagu dhejiyo ayaa sidoo kale ah mid ka mid ah tilmaamaha muhiimka ah ee aan diiradda saareyno.

Jiil cusub oo tignoolajiyada gudbinta DC ah, gudbinta dabacsan ee DC waxay la mid tahay gudbinta HVDC qaab-dhismeedka, kaas oo wali ka kooban saldhigyada beddelayaasha iyo khadadka gudbinta DC. Si ka duwan nooca beddelaha isha ee hadda jira ee gudbinta HVDC oo ku salaysan tignoolajiyada wareejinta ee wejiga lagu xakameeyo, beddelaha ku jira gudbinta dabacsan ee DC waa beddelaha isha danabka (VSC), kaas oo lagu garto isticmaalka aaladaha la beddeli karo (badanaa IGBT) iyo tignoolajiyada wax-ka-beddelka soo noqnoqda sare. Sannadihii ugu dambeeyay, gudbinta dabacsan ee DC ayaa u koraysa heerka danabka iyo awoodda sare.

Xaaladda codsiga ee IGBT: IGBT waxa ka buuxa tuubo laba-geesood ah oo albaab dahaaran, kaas oo la damin karo, waxa uu leeyahay faa'iidooyinka khasaaraha yar iyo xakamaynta fudud, waxaana loo arki karaa CPU-ga gudbinta tooska ah ee jilicsan. Waqtigan xaadirka ah, IGBT-ga lagu dabaqay mashruuca waa dhammaan alaabada la soo dejiyo, inta badan ABB iyo Siemens, halka IGBT-ga gudaha ee leh danab sare iyo awood sare leh uusan lahayn wax soo saar bisil. Waqtigan xaadirka ah, horumarka deegaanku waa mid gaabis ah, ku tiirsanaanta soo dejinta waa mid xooggan, khatartuna waa mid aad u weyn. Isla mar ahaantaana, kharashka IGBT wuxuu ka dhigan yahay qiyaastii 30% kharashka waalka.

Suurtagalnimada IGCT-ga cusub: Marka la eego suurtagalnimada IGBT ee Shiinaha oo hooseysa, waxaan isku dayeynaa inaan IGBT ku beddelno IGCT. Soo noqnoqoshada beddelka, awoodda wadista iyo waxqabadka kale ee IGCT-ga dhaqameed waa kuwo ka hooseeya IGBT, laakiin waxay leedahay faa'iidooyin gaar ah oo ku saabsan awoodda, khasaaraha gobolka, khasaaraha beddelka iyo kharashka (qiimaha alaabada leh awood isku mid ah waa qiyaastii 1/2 IGBT). Si kastaba ha ahaatee, haddii IGCT-ga dhaqameed lagu dabaqo gudbinta awoodda dabacsan ee UHV, marka IGCT-ga la shido, diode-ka wuxuu soo saari doonaa koronto soo kabasho oo weyn, taas oo saameyn weyn ku yeelan doonta nidaamka. Sidaa darteed, si loo ilaaliyo diode-ka, waxaan baarnay ICCT-ga cusub annagoo ku darnay wareegyo nuugis oo dheeraad ah oo ku yaal module-ka dhaqameed ee IGCT si loo yareeyo saameynta nidaamka.

Codsiyada Cusub ee IGCT: Marka lagu daro wareegyada nuugista dheeraadka ah, naqshadeenna cusub ee IGCT waa mid aad u yar waxayna leedahay iska caabin saameyn sare leh iyo isku hallayn sare, sidaa darteed waxaan soo saari karnaa agabyada dahaarka leh isku hallayn dahaar sare leh iyo xoog farsamo. Xd Power System Co., Ltd. waxay horay u baareysaa agabka dahaarka ee wareegga nuugista IGCT ee mashruuca Yunnan Maitrei. Haddii naqshaddu ku salaysan tahay nidaamka XD Power, tirada modules-ka IGCT waxaa la dhimi doonaa qiyaastii 3% marka la barbar dhigo IGBT, wadarta guud ee walxaha dahaarka waxay noqon doontaa 2-3 jeer ka badan IGBT.
