Research on protection block strategy of grounding faults in HVDC converter station

DC grounding fault is a typical fault for HVDC system. In order to obtain smoother, faster, and more secure transient process, the DC protection block strategy is used to remove and isolate the converter to prevent the accident enlargement and reduce the impact on devices and power grid when the gro...
