• We model a hybrid SFCL which solves a late recovery time after quenching.
• We examine the hybrid SFCL to the Dangjin multi-unit power plant in Korea.
• The hybrid SFCL decreases the acceleration power of the generators during a fault.
• Reducing tripped generators is verified that transient stability will be improved.
Additional power generation sites have been limited in Korea, despite the fact load demands are gradually increasing. In order to meet these increasing demands, Korea’s power system company has begun constructing new generators at existing sites. Thus, multi-unit plants can create problems in terms of transient stability when a large disturbance occurs. This paper proposes a hybrid superconducting fault current limiter (SFCL) application to enhance the transient stability of multi-unit power plants. SFCLs reduce fault currents, and limitation currents decrease the imbalance of the mechanical and electrical torque of the generators, resulting in an improvement in transient stability.
