Abstract

Abstract—This paper presents a transient based protection
principle utilising the magnitude of the travelling wave power
derivative at only local terminal to formulate a non-unit
protection scheme, where the directional transient relay and
boundary relay have been involved. In terms of boundary relay,
for an internal fault in the forward direction with respect to a
local relay, the traveling wave power derivative will exceed a
pre-determined setting, otherwise the fault is external to the
relay, due to the discontinuity of surge impedance at the
boundary point. Directional detection is achieved by the
comparison of the forward travelling wave power to the
backward travelling wave power. The ratio of forward traveling
wave to backward traveling wave is less than unity for all
forward directional faults and much greater than unity for
reverse directional faults. Simulation studies carried out in
PSCAD and the results presented shows the suitability of the
proposed protection principle as all fault scenario indicated
were detected within 250µs following the application of the
faults.
