Currently, ABB is continuing to upgrade this technology. In the new phase, ABB's lightweight HVDC technology will double the transmission capacity to 3,000 MW. The upgraded system design is more compact, and the power transmission capacity per unit area is increased by 350%. Given the many requirements for offshore station or onshore installations for converter stations, the new design will bring significant benefits to projects such as offshore wind or grid interconnection. The technology is based on technological innovations in semiconductor power electronic components, doubling power transmission capacity and transmission distance, enabling better control of high-voltage DC systems, reducing floor space and improving economy.
Fang Qin, president of ABB's power grid business unit, said: "ABB took the lead in applying high-voltage DC technology in the 1950s, and the birth of the 1997 young high-voltage DC technology is one of the most important milestones in our innovation journey. This year is the item. On the 20th anniversary of the technological breakthrough, we will once again write a new chapter to achieve longer distances and minimize losses. HVDC technology is one of the important cornerstones of ABB's new phase strategy, which will further strengthen us as a stronger, A preferred partner status for smarter, greener grids."
ABB's lightweight HVDC technology revolutionizes large-capacity, long-distance power transmission in underground, subsea and overhead lines. Due to its excellent versatility, the technology solves the problem of tight land use. At the same time, it also achieves cross-border grid interconnection, access and balance of renewable energy, and cross-border power trading. The technology will also be widely used in offshore wind and shore projects by installing converter stations on offshore platforms.
Light-duty high-voltage DC technology has achieved a leap forward in the past two decades, with transmission capacity increasing from 50 MW to 1400 MW, nearly 30 times higher, meeting the power needs of millions of households; voltage rating from 80 The kilovolt is increased to 525 kV; the transmission distance is increased from 70 km to more than 1000 km; the transmission loss is reduced to less than 1%.
Today, ABB is a technology leader in the field of light HVDC, participating in 18 of the world's 24 light HVDC projects, creating a number of world records, such as the world's longest underground project, the highest power offshore. Wind power project, and the first overhead line project.
The latest technology upgrades increase the voltage level to 640 kV and increase the transmission distance to 2,000 km, enabling more grid-connected renewable energy and longer-distance grid interconnections, and the loss is further reduced. All of these upgrades save the grid company huge costs and bring greater benefits. The latest ABBAbility-based MACH control system will further improve efficiency and reliability, and the latest converter stations further enhance the design that includes environmental aesthetics.
ABB pioneered the application of high-voltage DC technology more than 60 years ago. It is a global market leader and has participated in more than 110 HVDC projects with a total installed capacity of 120 GW, accounting for about half of the global total.
ABB is a global technology leader in electrical products, robotics and motion control, industrial automation and power grids, helping customers in the power, industrial, transportation and infrastructure industries improve their performance. Based on more than 125 years of innovation history, ABB is constantly pushing the energy revolution and the fourth industrial revolution to write the digital future of the industry.
