Influence of transition resistance and fault moment on DC system commutation process caused by two-phase fault of AC system

Influence of transition resistance and fault moment on DC system commutation process caused by two-phase fault of AC system

Commutation failure caused by the fault of AC system at inverter side seriously affects the safety and stability of high-voltage direct current (HVDC) system. Although two-phase fault is a typical asymmetrical fault, the studies on commutation failure caused by two-phase fault are few compared with...
