Analysis of Two Cases of Line Restart Process Encountered by an Actual HVDC Inverter Station
In the HVDC transmission system,the instantaneous failure of HVDC line will cause HVDC system to restart.Based on two restart events in a HVDC inverter station,the restart logic of HVDC line and control mode of HVDC trans-mission system are analyzed by reviewing the fault process.The restart process is analyzed by referring to fault recording,and the operation and maintenance suggestions are given.
