A novel mathematical morphology filter for the accurate fault location in power transmission lines

Abstract: The performance of Multi-resolution Morphology Gradient(MMG)-based fault location scheme in power transmission lines will deteriorate when the noise is imposed on the transient signals. In this paper, a novel mathematical morphology filter Dierion is proposed to effectively reduce the noise in the transient signals and improve the performance of the accurate fault location using MMG. This proposed filter with parameters ( , ) extracts the th element in the sorted input signal according to the structure element… Show more

“…Em [89], a MM é aplicada na redução de ruídos na proteção de linhas AC. Em [35] e [66], os FRR's são aplicados ao problema de localização de faltas em linhas HVCA. Note que, estes trabalhos não tratam da localização de faltas em linhas HVDC.…”
