Recently, ABB announced that it will provide key high-voltage direct current technologies for the UK State Grid Corporation and the French grid company (RTE) to help the two grid to achieve interconnection.

ABB's investment in grid interconnection projects amounted to € 270 million, which will help to further integrate the UK and French electricity markets. The transmission line has a power of 1 million kilowatts, starting from Chilling, in the south of England, through the English Channel, ending at Tourbe in northern France for a total length of 240 kilometers.
 
ABB will provide two light, high pressure direct current converter stations for the project, installed in France and the UK, and connected to submarine cables. Converter station in the transmission and distribution process, commitment to AC and DC conversion function. Power is long-distance transmission is DC, before the distribution to the user, DC need to be converted into alternating current. The biggest advantage of high-voltage DC is to achieve large capacity, long-range efficient and reliable transmission, and the power loss to a minimum. ABB's light, high-voltage DC technology also has a number of advantages, such as adjusting the power grid fluctuations, when the failure to help restore power and so on. These advantages will bring greater economic benefits to grid operators and achieve stable power supply for end users.
 
"The project further strengthens our leading position in the field of high voltage direct current and further promotes our profitability growth as a preferred partner for a stronger, smarter and greener grid," said Fang Qin, President of ABB Power Grid Division.
 
ABB's commutation station will install ABB's advanced MACH ™ control and protection system, which is an important part of the ABB Ability ™ digital solution. MACH is equivalent to the brain of a high voltage DC line, monitoring, controlling and protecting the complex technology of the converter station system and managing the interchange of various operating conditions to achieve reliable power supply. ABB's products also integrate advanced fault logging and remote control functions, and can protect the system from lightning and other sudden damage to the situation.
 
ABB has been the first to use HVDC technology more than 60 years ago and is currently involved in more than 110 HVDC projects worldwide with a total installed capacity of more than 120 million kilowatts, accounting for half of the world's total installed capacity. In the 1990s, ABB pioneered the use of light-duty high-voltage DC technology, and gradually applied to the world has been installed to run the 24 light high-voltage DC project in 18. ABB's HVDC technology has helped more than 15 countries to achieve reliable transmission of long distances.
