ABB to Upgrade First HVDC Subsea Link Between Sweden and Denmark
ABB has won an order worth around $30 million from Svenska Kraftnät in Sweden and Energinet in Denmark.
ABB will upgrade the control and protection system for the Konti-Skan high-voltage direct current (HVDC) transmission link with its latest ABB Ability MACH technology.
The Konti-Skan transmission link was built 52 years ago as the first interconnection between Sweden and Denmark enabling electricity exchange. This provided the benefits of a shared grid with additional features from the HVDC system, which has enabled the exchange of renewable hydropower and wind energy for decades. The installation of ABB’s latest MACH control and protection system should extend the life span of the HVDC link.
The ABB Ability MACH system acts like the brain of the HVDC link – monitoring, controlling and protecting the technology.
“We are delighted to implement our latest ABB Ability MACH control technology to upgrade this historic HVDC transmission link, facilitating more energy trading and exchange of renewables, bringing clean, reliable power supply to consumers,” said Claudio Facchin, president of ABB’s Power Grids division. “This project reiterates our strategic focus on service and digital technologies and reinforces our market and technology leading position in HVDC as a partner of choice for enabling a stronger, smarter and greener grid.”
Konti-Skan was built in two phases, beginning in 1965 with Konti-Skan 1, followed by Konti-Skan 2 in 1988. ABB’s technology will enable the two to work together as a single system. The full system upgrade involves the replacement of the control system.
