Abstract

After the operation of JinSu UHVDC transmission line, influence on the stability of the interconnected power grid especially in de-icing modes is studied from various sides. To cope with the DC block fault occurred in the UHVDC transmission line, the coordinated control strategy based on emergency DC power supply is researched, by which the total amount of load shedding and generator tripping can be reduced. According to the comparison and selection of generator tripping schemes, the voltage rise near sending-end after DC block fault is taken into account. The influence on power system stability is analyzed in two UHVDC de-icing modes. The feasibility and validity of these de-icing modes is proved.
