Hyosung Heavy Industries to Localize Key 2-GW-Class HVDC Technologies by 2027

Held Meeting to Review Progress on Localizing West Coast HVDC Technology
Completed Development of Key Algorithms and Converter Valve Components
Plans On-Site Installation and Commissioning by 2030

Hyosung Heavy Industries plans to localize key technologies for 2-gigawatt (GW)-class voltage-source high-voltage direct current (HVDC) transmission by 2027. The company said it held a meeting to review progress on localizing West Coast HVDC technology at the Korea Chamber of Commerce and Industry in Jung-gu, Seoul, on Oct. 23, where it shared its technology development achievements and future schedule.

About 100 people from the government, industry and academia attended the event, including Vice Minister Lee Hohyun of the Ministry of Climate, Energy and Environment and Kim Jaegun, vice president of Korea Electric Power Corporation. In September, Hyosung Heavy Industries was selected as the lead company for valves and control systems in Korea Electric Power Corporation's project to localize and demonstrate large-capacity voltage-source HVDC technology.

Hyosung Heavy Industries is pursuing the development of a 2-GW-class system based on technology validated through an existing 200-megawatt (MW)-class HVDC demonstration project. It has completed development of key algorithms required for system design and submodules, major components of converter valves, and is also developing 525-kilovolt (kV)-class converter valves. It has also established a simulation testing environment to verify the control system's performance before applying it to the actual power grid.

Hyosung Heavy Industries plans to complete key technology development and system design by 2027, then manufacture major equipment and conduct performance tests, before proceeding with on-site installation and commissioning for the West Coast HVDC system by 2030.

Woo Taehee, CEO of Hyosung Heavy Industries, said, "We will do our best to ensure that plans for a joint development agreement at the end of the year, the formation of a special-purpose corporation and the development of HVDC transformers proceed as scheduled."
