Feasibility and Simulation Study of DC Hybrid Circuit Breakers

Shang, Yang 07 July 2014 (has links)
Interruption of DC is more challenging than that of AC because of the absence of DC zero-crossings. This thesis proposes an alternative counter-voltage (ACV) DC hybrid circuit breaker (DC-HCB). This DC-HCB can interrupt the DC up to 5 kA with the source voltage of up to 1 kV and it can meet the general requirements i.e., interrupting the DC within 5ms, and limiting over-voltages due to the CB operation. The existing/investigated DC circuit breakers, i.e., active mode DC-HCB and the traditional counter-voltage (TCV) DC-HCB are also investigated and compared with the proposed DC-HCB. The investigations are based on the time-domain simulation studies in the PSCAD/EMTDC. The studies show that the ACV DC-HCB is the preferred option to both the existing DC-HCBs. The main features of the proposed ACV DC-HCB include lower capacitance in the commutation path and the need for a smaller dielectric strength for the primary-path circuit breaker.
