Under the $16m contract, ABB will install its state-of-the-art MACH control and protection system to enhance performance and reliability of the 600MW Kontek HVDC interconnection link.
The project scope also includes installation of remote operator work stations, training and spares parts.
Originally delivered by ABB in 1995, the link will be upgraded to help improve the operational reliability of the link and reduce maintenance needs.
The upgraded link is expected to enter service in 2016.
ABB Power Systems division Grid Systems business head Hanspeter Faessler said: "This upgrade reinforces ABB’s focus and commitment to supporting customers throughout the lifecycle of the products and systems it delivers.
"It also underlines the company’s growing focus on service business."
The contract marks the ABB’s 23rd major HVDC modernization project since 1990, including 17 control system upgrades.
The MACH system is a control solution deployed for HVDC and Flexible Alternating Current Transmission Systems (FACTS) installations, with over 1,100 such systems in operation throughout the world.
