Abstract:Based on the experience of engineering operation and maintenance, taking ±800kV Kunliulong ultra high voltage (UHV) hybrid multi-terminal DC project as an example, this paper introduces the multi-terminal DC operation wiring mode, analyzes the multi-terminal DC fault and different operation modes after exiting the station. The change of DC transmission capacity and the degree of load loss under different disposal methods are described, which can provide preference for the disposal of outgoing faults in the on-site operation and maintenance of multi-terminal DC.
