In order to improve fault recovery characteristic of high-voltage direct current transmission system(HVDC), this paper proposes voltage dependent current order limiter(VDCOL), optimizing arc extinguishing angle controlling and adopting SVC reactive power compensator and so on to improve fault recovery feature after analyzing the main factors influencing fault recovery characteristic. This paper makes...
