ABB announces improvements to High Voltage Direct Current (HVDC) Light technology

May 3, 2017 --ABB announced the latest development in high voltage direct current (HVDC) Lightmaking it possible to reliably transmit large amounts of electricity over greater distances.

The next level of ABB’s HVDC Light will enable doubling the power capacity to 3,000 megawatts (MW). System design enhancements will bring a step change in compactness, with a potential to deliver 350 percent more power per square meter of space used – suitable in applications like offshore wind or interconnections, in terms of converter station footprint be it on offshore platforms or onshore installations. ABB’s advances were made possible with the development of semiconductor-based power electronic devices that provide greater control.

ABB’s HVDC Light technology is a solution for applications with space limitations. It enabled interconnections between countries to support the integration and balancing of renewables while facilitating electricity trading. It has also been deployed to integrate offshore wind energy and bring the power to shore, via converter stations positioned on offshore platforms.

The last two decades have seen advances in this technology. Power capacity has gone up nearly 30 times from 50 to 1400 MW – enough electricity to power several million households. Voltage levels have gone up from 80 to 525 kilovolts (kV), and distance capability from 70 to over 1,000 kilometers (km). At the same time transmission losses have been brought down to less than 1 percent.

ABB has delivered 18 out of 24 VSC HVDC projects commissioned in the world, including several world records such as the world’s longest underground link, the most powerful offshore wind connection and the first overhead link deploying this technology.

With a higher voltage capability of up to 640 kV, the latest technology extends distance capability – doubling it to 2000 km – making it possible to transmit electricity over elonger distances, enabling more renewables to be integrated and longer interconnections to be built.
