Differentiation of Fault and Load Change in HVDC System using Amplitude Tracking Square Wave

| الملخص: | For a HVDC system, a reliable power system protection
should be quick and precise in identifying fault. It is also
equally important to ensure some events that could be mistaken
for fault to not trigger false alarm, for example load change.
Wavelet transform is one of the well-known tools that is able
to achieve this purpose. In this paper, the fault analysis using
a novel Amplitude Tracking Square Wave (ATSW) is studied.
The algorithm is very easy to be implemented, as only timedomain
analysis is involved. Notwithstanding the low complexity,
it can work as effective as the wavelet transform, as proven by
comparing the results obtained from these two signal processing
techniques. |
