Hyosung Heavy Industries develops 2-GW-class HVDC algorithm, accelerates localization

[Financial News] Hyosung Heavy Industries has completed development of core algorithms for 2-gigawatt (GW)-class voltage-source HVDC and submodules for converter valves, for use in the West Coast HVDC project. The company plans to complete development of core technologies and system design by next year, and to carry out on-site installation and commissioning by 2030.
Hyosung Heavy Industries said it held the “West Coast HVDC Localization Progress Review Meeting” on the 23rd at the Korea Chamber of Commerce and Industry in Jung-gu, Seoul, with about 100 attendees from government, industry, academia and relevant associations, including Vice Minister Lee Ho-hyun of the Ministry of Climate, Energy and Environment and Korea Electric Power Corporation (KEPCO) Vice President Kim Jae-gun.
HVDC is a technology that converts alternating-current power into direct current for transmission and is used to transmit large amounts of electricity over long distances. Hyosung Heavy Industries is developing 2-GW-class voltage-source HVDC technology based on technology validated in its previous 200-megawatt (MW)-class HVDC demonstration project.
Hyosung Heavy Industries said it has completed development of the core algorithms needed to design a 2-GW-class HVDC system and submodules, a key component of converter valves. Building on this, it is developing 525-kilovolt (kV)-class converter valves and has also set up a hardware-in-the-loop simulation (HILS) test environment to verify control system performance before applying the technology to an actual power grid.
Hyosung Heavy Industries plans to improve the performance of control systems, converter valves and transformers needed to expand transmission capacity, and complete the localization of key technologies and system design by next year. It will then manufacture key equipment and conduct performance tests before proceeding with on-site installation and commissioning for the West Coast HVDC project by 2030.
Hyosung Heavy Industries CEO Woo Tae-hee said, “I will do my best to ensure that scheduled milestones, including a joint development agreement at year-end, the establishment of a special-purpose company, and development of an HVDC transformer, proceed as planned.”
