Fault Detection and Interruption in an Earthed HVDC Grid Using ROCOV and Hybrid DC Breakers

  title={Fault Detection and Interruption in an Earthed HVDC Grid Using ROCOV and Hybrid DC Breakers},
  author={Jeremy Sneath and Athula D. Rajapakse},
  journal={IEEE Transactions on Power Delivery},
Different HVDC grid types and the respective protection options are discussed. An earthed bipole HVDC grid was modeled in PSCAD, and using simulation results, the necessity of di/dt limiting inductors to contain the rise of fault currents within the capacity of current hybrid dc breakers is demonstrated. The impact of different inductor sizes on current rise was studied. A fault detection and localization scheme using the rate of change of voltage measured at the line side of the di/dt limiting… CONTINUE READING
