Abstract
Series reactors as fault current limiters (FCLs) are extensively employed to enhance power grid protection issues. Utilizing superconducting technology is a viable solution to approach FCLs toward commercializing. The concern of transient recovery voltage (TRV) of the circuit breaker becomes more considerable due to FCL’s high stored energy in the case of fault current limiting mode. This paper firstly focuses on the analysis of TRV under the presence of an inductive-based superconducting fault current limiter (SFCL) installed in a power grid, and then it investigates the impact of a controllable
superconducting series reactor (CSSR) in TRV of the circuit breaker. The obtained results show that the synchronous operation of a CSSR with a circuit breaker substantially declines TRV.
