Abstract
Since DC has no zero point, an arc occurs when the DC circuit breaker performs a shutdown operation. In this case, a fatal accident may occur in the circuit breaker or in the grid, depending on the magnitude of the arc. Therefore, the shutdown performance and the reliability of the circuit breaker are important in the commercialization of HVDC. In this study, a superconducting LC circuit breaker was proposed to improve the performance and the reliability of the DC circuit breaker. The superconducting LC circuit breaker applied a superconducting coil to the inductor of the existing LC circuit breaker. Other than limiting the initial fault current, it also creates a stable zero point in the event of a fault current. To verify this, simulation was performed through EMTDC/PSCAD. Furthermore, the superconducting LC circuit breaker was compared with the LC circuit breaker with a normal coil. As a result, it was found that the LC circuit breaker with the superconducting coil limited the initial fault current further by approximately 12 kA compared to the LC circuit breaker with a normal coil. This reduced the arc extinguish time by approximately 0.16 sec, thereby decreasing the elctrical power burden on the circuit breaker.
