Hyosung Heavy Industries "Complete development and design of core technology for 2GW ultra-high voltage direct current transmission next year"

West Coast HVDC localization progress inspection meeting... On-site installation and test run in 2030

(Seoul = Yonhap News) Reporter Lim Seong-ho = Hyosung Heavy Industries announced that it will complete the development of core technology for the high-voltage direct current transmission (HVDC) 2GW (gigawatt) high-capacity system, which is the center of the government's 'West Coast Energy Highway' project, by next year.

Hyosung Heavy Industries announced that it held a 'West Coast HVDC localization status inspection meeting' at the Korea Chamber of Commerce and Industry in Jung-gu, Seoul on the 23rd with the attendance of about 100 officials from the government, industry, academia, and related associations, including Vice Minister of Climate, Energy and Environment Lee Ho-hyun and Korea Electric Power Corporation Vice President Kim Jae-gun.

Hyosung Heavy Industries explained the status of development of 2GW-class voltage-type HVDC core technology based on technology verified in the existing 200MW (megawatt) HVDC demonstration project. They also announced plans to complete local production of key technologies by next year by improving the performance of control systems, converter valves, and transformers required to expand transmission capacity.

As a specific development achievement, it was introduced that the development of the core algorithm necessary for designing a 2GW HVDC system was completed. In addition, the company added that it has completed the development of a submodule, a key component of the converter valve, and is also developing a 525 kV (kilovolt) class converter valve.

Based on these achievements, Hyosung Heavy Industries plans to complete the development of HVDC core technology and system design by next year, manufacture major equipment and perform performance tests, and proceed with field installation and test operation for the construction of HVDC on the West Coast by 2030.

The West Coast Energy Highway, a government task, is a project to build a power grid necessary for future growth, including high-tech industries. The key is to build four HVDC transmission networks that transport large-scale renewable energy produced in the West Coast area to major demand sources.

Last month, Hyosung Heavy Industries was selected as a participating company in the valve and controller field of Korea Electric Power Corporation's 'Large Capacity Voltage HVDC Localization and Demonstration Project' and is pursuing the localization of 2GW HVDC system technology.

Woo Tae-hee, CEO of Hyosung Heavy Industries, said, "We will do our best to ensure that the scheduled schedules, such as the year-end joint development agreement, formation of a special purpose corporation, and HVDC transformer development, are carried out as planned."
