ABB will refurbish the stations that convert alternating current to direct current and back on the 560MW Inga-Kolwezi power transmission link. The 1,700km system was built by the company in 1982.
The link uses high-voltage direct current (HVDC) technology to transmit power from the Inga Falls hydropower station on the Congo river to the mining district of Katanga in the south-east of the country. It also enables excess power to be exported to the Southern African power pool countries.
ABB will be responsible for system engineering, including design, supply and installation of new thyristor valves, high-voltage apparatus and MACH2 control and protection system. The project is scheduled for delivery in 2013.
Peter Leupp, head of ABB’s power systems division, said: “This refurbishment will enhance the reliability of the grid and ensure efficient transmission of hydro electricity across the region. We are delighted to contribute to the development of the power infrastructure in the country and remain committed to the harnessing of renewable energy.”
