Abstract
Utilizing superconducting technology in fault current limiters for power grid applications is a practical solution to achieve a more modern and efficient power system. This is due to their low-loss profile, high efficiency, and ability to transmit about 5x more power in the same footprint compared to conventional counterparts. In addition, the integration of renewable energy resources into power grids makes the use of fast circuit breakers essential. However, the Transient Recovery Voltage (TRV) of fast mechanical circuit breakers stays a concern. This paper studies the TRV of a fast circuit breaker during a fault condition. Then the effect of a solid-state superconducting series reactor (SSSR) on the TRV of the circuit breaker is investigated and compared using an analytical model, simulation studies, and experimental testing. The results prove that an SSSR significantly diminishes the TRV of the fast breaker and offers an effective superconducting solution for modern power grids.
