ABB In­dia flags off its first 800kV UHVDC trans­former

Electrical Monitor - - NEWS -

BB In­dia re­cently rolled out the first 800kV con­verter trans­former man­u­fac­tured at its Vado­dara fa­cil­ity in Gu­jarat. Weigh­ing around 300 tonnes, the trans­former will be in­stalled at Power Grid Cor­po­ra­tion of In­dia’s Agra sub­sta­tion in Ut­tar Pradesh. The trans­former is part of the 800kV, 6000-mw North East-Agra UHVDC trans­mis­sion link span­ning over 1,750 km.

UHVDC (ul­tra high volt­age direct cur­rent) is the tech­nol­ogy of choice for long-dis­tance bulk power trans­mis­sion glob­ally. The up­com­ing UHVDC line will en­able evac­u­a­tion and trans­mis­sion of clean en­ergy from the North East to load cen­ters of North In­dia. “It also brings cheaper

Apower from the states of Mad­hya Pradesh and Ch­hat­tis­garh to the North East­ern Re­gion with min­i­mal losses,” said Pi­ta­m­ber Shiv­nani, Pres­i­dent, Power Prod­ucts Di­vi­sion, ABB In­dia.

“As we up­grade the trans­mis­sion net­work in the coun­try, this mile­stone demon­strates that ABB is a well-po­si­tioned part­ner in our plans of bring­ing qual­ity power to all,” said R.P. Sas­mal, Di­rec­tor (Oper­a­tions), PGCIL, who flagged off the con­verter trans­former from the man­u­fac­tur­ing fa­cil­ity.

When fully com­mis­sioned in 2016, the North-East Agra link will be­come the world’s first mul­ti­ter­mi­nal UHVDC con­nec­tion. From the fa­cil­ity in Vado­dara, ABB has al­ready sup­plied six 400kV con­verter trans­form­ers for this project for in­stal­la­tion at Alipur­d­uar sub­sta­tions in West Ben­gal.

ABB has been man­u­fac­tur­ing power prod­ucts in In­dia for more than five decades. It com­menced man­u­fac­tur­ing of trans­form­ers at its Vado­dara fa­cil­ity in 1999 and over time ex­panded its port­fo­lio to be­come a ma­jor man­u­fac­turer of EHV and UHV trans­form­ers and re­ac­tors in In­dia, a com­pany release noted.
