Design and parametric study of active-type resonance HVDC circuit breaker

The important requirement of High-Voltage Direct Current (HVDC) multi-terminal system is the mature Circuit Breaker (CB). In this paper, the systematic mathematical modeling is implemented to design resonance circuit parameters of Active type resonance HVDC CB. The designed model of CB is tested on three cases, namely, fault current, load current and system inductance variation. These cases are compared based on total time required to reduce fault current to residual current and to de-energize breaker system. The simulation results for these conditions validate the performance of designed HVDC CB.
