Lin Li-hu · Nanfang dianwang jishu · 2014
Traveling-wave signal analysis of transmission lines vegetation-related faults adopts the methods of wavelet analysis and common signal processing,eliminates high frequency interference signals from the transmission lines itself and hardware noise signals,achieves the goals of extracting vegetation flashover fault characteristic signal accurately and efficiently. Results indicates that the characteristic signal of vegetation flashover failure acquired from the transmission line traveling wave analysis can better highlight the fault characteristic and improve fault location result than that from the traveling wave signal.
