The advantages of low-voltage direct current (LVDC) distribution power systems are emerging with the proliferation of distributed generators and power electronic devices. In comparison with the existing LVDC application in telecommunication, vehicle, ship and traction systems, LVDC distribution power systems concern more protection for safety, especially protection against electric shock caused by...
In this paper we show that the HVDC converter transformer valve side has the diversity and space-time discrete. Considering the influence of failure time on the fault feature, this paper proposes a method of fault feature stage dividing. The basis of fault feature stage dividing is given, and simulation result is showed for comparison. The protection test and BPP strategy research is also discussed...
