There is a smoothing reactor and DC filter between the inverter and the direct current line to form a boundary in the HVDC transmission system. Since this boundary presents the stop-band characteristic to the high frequency transient voltage signals, the high-frequency transient voltage signal caused by external faults through boundary will be attenuated(More)

The protection based on fault transient component could overcome the disadvantages of traditional industrial frequency protection such as poor anti-CT saturation ability and long operating time.This paper presents a novel ultra high speed bus protection based on transient energy,which takes the voltage traveling wave and current traveling wave on each(More)
This pape presents artificial neutral network algorithm for fault type classification and fault distance location for all the types of faults for transmission line in triangle network. This technology uses only one end data and accurate fault distance location fault type identifying is achieved after half cycle from the inception of fault. The proposed(More)
