With the development of multi-source AC/DC distribution networks, DC fault detection technology has become the key to DC protection. Aiming at the characteristics of large fault current with a rapid rise and difficulty to extract fault features when

Single-phase ground fault is one of the main reasons in distribution network fault. The fault line selection is the key step of fault location. In this paper, Db4 transform is used to decompose and reconstruct the fault bus zero-sequence voltage and

The detection of zero sequence voltage is the key of judging asymmetric fault. However, the original voltage may contain a lot of harmonic pollution which decrease the detection accuracy of zero sequence voltage. To increase the detection accuracy, a
