Planning scheduling strategies to suppress the magnitudes of fault currents

With traditional circuit breakers, the interrupter capacity margin is insufficient. To increase interrupting capacity, the circuit breaker can be upgraded or a device can be installed to suppress the fault current, thereby correcting the small fault current margin. In this paper, the power dispatch method is used to suppress the fault current. Simulations are performed and summarized to show the best scheduling policy for increasing the breaker capacity margin to allow for safe operation of the system. Scheduling policies take advantage of existing equipment, so there is no need for any additional purchases for the system. The proposed method will be able to significantly reduce the fault current directly and effectively compared to traditional practices.
