Systematic Approach to HVDC Circuit Breaker Sizing [PDF]
IEEE Transactions on Power Delivery, 2020 High-voltage direct current (HVDC) grids can be protected by HVDC circuit breakers (DCCB) to selectively clear DC side faults and assure continuous operation of the healthy parts in the grid. Line inductors in series with DCCBs are essential to reduce the rate of rise of the fault current and to slow down the voltage decline in the healthy parts of the
