Hyosung Heavy Industries announced on the 8th that it has recently established a Hardware-In-the-Loop Simulation (HILS) system at its heavy industry research institute in Gwacheon, Gyeonggi Province. The system allows for the verification of the performance and stability of its self-developed 2GW (gigawatt)-class ultra-high-voltage DC transmission (HVDC) controller in an environment similar to an actual power grid.
The HILS system established this time is a core testing system designed to ensure the stable application of GW-class, high-capacity HVDC to existing power grids.
As transmission capacity increases with HVDC, the control targets and conditions become more complex, significantly increasing the number of operational scenarios that must be verified, such as grid faults and emergency situations. In particular, for 2GW-class high-capacity systems, the number of scenarios requiring verification is two to three times greater than that of existing 200MW (megawatt)-class systems, making sufficient pre-verification essential before application to an actual grid.
The HILS system connects a virtual 2GW-class converter valve and power grid to an actual HVDC controller, verifying the stable response of the control system in an environment similar to real-world conditions. In particular, by simulating hazardous situations that are difficult to test on an actual power grid in a virtual environment, long-term repeated testing is possible, thereby enhancing the stability and reliability of the HVDC controller.
Based on its self-developed HVDC controller, Hyosung Heavy Industries has secured technology covering the entire process of the HILS system, from design to installation, testing, and operation. In particular, it leveraged the know-how accumulated in actual power grid control, operation, and verification through the 200MW-class voltage-source HVDC installed at the Yangju Substation for this 2GW-class test environment setup.
Hyosung Heavy Industries has been promoting the domestication of Korea's HVDC technology by securing independent technical capabilities ranging from core equipment development to system construction and actual grid operation. In September, it was selected as a participating company in the valve and controller sector of the "High-Capacity Voltage-Source HVDC Domestication and Demonstration Project" being promoted by KEPCO.
High-capacity voltage-source HVDC is a field that has been led by a small number of global companies. Hyosung Heavy Industries plans to promote the West Coast Energy Expressway project by enhancing the reliability of GW-class domestic HVDC systems through this HILS setup.
A representative from Hyosung Heavy Industries stated, "The significance of establishing this HILS system lies not only in securing a testing facility but also in establishing an independent technical foundation that allows us to further advance our self-developed 2GW-class HVDC controller." The representative added, "Based on this, we will continue to expand our entry into the global HVDC market through domestic independent technology."
