Mechanical DC circuit breaker model for real time simulations
International Journal of Electrical Power & Energy Systems, 2019 Abstract The main goal of the paper is the modeling of the mechanical circuit breaker (MCB) that can replicate the breaker characteristics in real time environment. The proposed MCB with active current injection is modelled for a system level, which provides adequate representation of the circuit breakers for system analysis studies. External current-
