ABB on April 25 announced the latest developments in the field of HVDC. Light HVDC is ABB's breakthrough technology pioneered 20 years ago, enabling reliable, cost-effective and efficient transmission of power over greater distances. ABB Power Grid is the preferred partner for building or upgrading power infrastructure customers around the world.

ABB is continuing to upgrade the technology. The new phase of ABB's HVDC technology will double its transmission capacity to 3,000 megawatts. The upgraded system is designed to be more compact with a 350% increase in power transmission capacity per unit area. Given the many requirements of the offshore platform or the land-based installation of the converter station, the new design will bring huge benefits to projects such as offshore wind power or grid interconnection. Based on technological innovations in semiconductor power electronic components, the technology doubles the power transmission capacity and transmission distance to better control the HVDC system, reducing the footprint and improving economy.

Fang Qin, President of ABB's Power Grid Division, said: "ABB pioneered the application of HVDC technology in the 1950s and the birth of HVDC in 1997 was one of the most important milestones in our journey of innovation. The 20th anniversary of the technological breakthrough, we will write a new chapter again, to achieve greater transport and loss to a minimum.HVDC technology is ABB's new stage one of the cornerstones of the strategy, it will further consolidate our more powerful, The preferred partner for a smarter, greener grid. "

ABB's Light HVDC technology revolutionizes large-capacity, long-distance power transmission of underground, submarine and overhead lines. Due to its superior versatility, the technology solves the problem of land tension. At the same time, it also enables interconnection of transnational power grids, access to and balance of renewable energy sources, and transnational power transactions. The technology will also be widely used in offshore wind and shore power projects by installing converter stations on offshore platforms.

Light HVDC technology has achieved leaps and bounds over the past two decades by increasing transmission capacity from 50 MW to 1400 MW, nearly 30 times higher, to meet the electricity needs of millions of households; from 80 KV to 525 kV; transmission distance increased from 70 km to more than 1000 km; transmission loss reduced to less than 1%.

Today, ABB is a technology leader in the field of HVDC and participates in 18 of the 24 HVDC projects in operation worldwide, creating numerous world records such as the world's longest underground project, the most powerful offshore Wind power project, and the first project of overhead line.

The latest technology upgrades have increased voltage levels to 640 kV and increased transmission distances to 2,000 km, resulting in more renewable energy grid interconnections and longer grid interconnections, with further reductions in losses. All of these upgrades save huge costs and bring greater benefits to grid companies. The latest ABBAbility based MACH security system will further improve the efficiency and reliability, the latest converter station to further enhance the design that contains the environmental aesthetics.

ABB pioneered the application of HVDC technology more than 60 years ago and is a global market leader with more than 110 HVDC projects in total installed capacity of 120 GW, accounting for about half of the global total.
