| Abstract: | A rare accident happened in Ningxia power grid due to the failure of the switching of DCcomponent caused by short- circuit current switching, combined with the current configuration ofrelay protection and reclosing mode, puts forward solutions through adjusting reclosing mode, andapplication in Ningxia power system, the results show that this method can effectively solve the DCcomponent problems caused by short circuit current change. |
