Abstract :
The analysis of fault-induced transients in three-phase overhead transmission lines can provide extensive information about the fault type, detection, location, direction, and sustained time in satisfactory agreement with real application in protective relays. In this paper, the wavelet coefficient energies of the Maximal Overlap Discrete Wavelet Transform regarding the fault-induced transients were used for real-time fault classification in transmission lines. The performance of the real-time fault classification was evaluated by means of the Real Time Digital Simulator (RTDS) and good results were obtained. The performance of the method was also off-line evaluated with actual oscillographic records of a Brazilian Power System Utility and good results were also obtained.
