Abstract The recovery characteristic after AC fault is an important index of the control performance of DC system. The fast and stable recovery of DC system is beneficial to the stable operation of AC system. The parameter setting of DC system controller is a key factor affecting the recovery characteristics after AC fault. For different DC projects, the control parameters need to be adjusted according to the results of dynamic performance test. Aiming at the problems encountered in the dynamic performance test of Belo Monte Ⅱ UHVDC Project in Brazil, analyze the causes and propose solutions, the recovery characteristics after AC fault are improved by adjusting control parameters, which meets the engineering requirements. It can be used for reference to improve the recovery characteristics of other DC projects.

Key words： ultra high voltage direct current (UHVDC) AC fault recovery characteristics control parameters
