Frequency domain analysis of HVDC grid non-unit protection
15th International Conference on Developments in Power System Protection (DPSP 2020)(2020)
摘要
Owing to the fact that the propagated travelling waves following a DC fault in HVDC grids consist of a wide range of frequencies, frequency domain analysis provides a useful means to assess DC protection schemes, including non-unit protection schemes. Non-unit protection uses series inductors at key nodes to distinguish between internal and external faults, exploiting the fact that these inductors...
