Farqiga u dhexeeya gudbinta DC iyo AC

Marka laga eego dhinaca farsamada, qaadashada ±800 kV UHV DC gudbinta, bartamaha xariiqda uma baahna inay hoos u dhacdo, taasoo si toos ah u diri karta awood badan oo toos ah xarunta culeyska weyn; haddii ay dhacdo gudbinta barbar socota ee AC/DC, waxay isticmaali kartaa habaynta soo noqnoqoshada laba-geesoodka ah si ay si wax ku ool ah u joojiso gariirka gobolka ee soo noqnoqda hooseeya, iyo hagaajinta xadka xasilloonida ku meel gaarka ah (firfircoon) ee qaybta isgoyska; iyo xallinta dhibaatada ka gudubka hadda wareegga gaaban ee dhammaadka soo dhoweynta weyn ee shabakadda korontada. Iyada oo la qaadanayo gudbinta AC 1000kV, bartamaha waxaa lagu ridi karaa shaqada shabakadda; xoojinta shabakadda si loo taageero gudbinta awoodda DC ee baaxadda weyn; xallinta dhibaatooyinka hadda wareegga gaaban ee ka gudbaya heerka shabakadda dhammaadka soo dhoweynta weyn iyo awoodda gudbinta hoose ee khadka 500kV, iyo hagaajinta qaab-dhismeedka shabakadda korontada.

Marka laga hadlayo awoodda gudbinta iyo waxqabadka xasilloonida, iyadoo la adeegsanayo ±800 kV gudbinta UHV DC, xasilloonida gudbinta waxay ku xiran tahay saamiga wareegga gaaban ee wax ku oolka ah (ESCR) iyo joogtada inertia ee wax ku oolka ah (Hdc) ee shabakadda dhammaadka helitaanka, iyo sidoo kale qaab-dhismeedka shabakadda dhammaadka diritaanka. Marka la qaato gudbinta AC ee 1000 kV, awoodda gudbinta waxay ku xiran tahay awoodda wareegga gaaban ee barta taageerada kasta ee khadka iyo masaafada khadka gudbinta (masaafada u dhaxaysa meelaha hoos u dhaca ee laba saldhig oo isku xiga); xasilloonida gudbinta (awoodda isku-dubaridka) waxay ku xiran tahay baaxadda xagasha korontada ee barta hawlgalka (farqiga u dhexeeya xaglaha korontada ee labada daraf ee khadka).

Marka laga eego arrimaha farsamada ee muhiimka ah ee u baahan fiiro gaar ah, isticmaalka ±800 kV UHV DC gudbinta waa inay diiradda saartaa dheelitirka awoodda firfircoon ee falcelinta iyo kaydinta awoodda firfircoon iyo xasilloonida danabka ee dhammaadka helitaanka shabakadda, waana inay diiradda saartaa arrimaha amniga danabka nidaamka oo ay sababaan guuldarro isku mar ah oo ku timaadda beddelka wejiga ee nidaamka quudiyaha DC ee badan. Isticmaalka gudbinta AC ee 1000 kV waa inay fiiro gaar ah u yeelataa dhibaatooyinka hagaajinta wejiga nidaamka AC iyo xakamaynta danabka marka qaabka hawlgalka la beddelo; in fiiro gaar ah loo yeesho dhibaatooyinka sida wareejinta awoodda sare ee qaybaha daciifka ah ee xaaladaha cilladaha daran; iyo in fiiro gaar ah loo yeesho khataraha qarsoon ee shilalka mugdiga ee meelaha waaweyn iyo tallaabooyinkooda ka hortagga.
