Analysis model development and specification proposal of 154 kV SFCL for the application to a live grid in South Korea

• This paper presents a PSCAD/EMTDC analysis model of a 154 kV SFCL in Korea.
• The model realizes operating mechanisms of the SFCL, based on the experimental data.
• The mechanisms include the HTS quenching property for fault current and temperature.
• This paper proposes four candidate locations and some specifications of the SFCL.
• These are based on the application of the 154 kV SFCL to the Korean power system.

This study presents the development of a PSCAD/EMTDC analysis model for the 154 kV SFCL in South Korea, which will be applied to the Korean power system in 2015. The analysis model is developed by using the operating mechanism supported by the developer of the SFCL, KEPRI (Korea Electric Power Research Institute). And then this paper proposes some candidate locations and design specifications for the successful demonstration application of the 154 kV SFCL to Korean power systems.
