摘要：
After completion and operation of UHVDC, influence on stability of interconnected power grid is studied from multiple aspects. To cope with the DC block fault occurred in 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. Through the analysis on excitation currents of generation units near the receiving-end and the action of related generator protections after DC block fault, the influence of generator protections related to power grid on grid stability is explored. At last, influence on power system stability is analyzed in two UHVDC ice-melting modes.
