MA Jian-rong · Equipment Manufacturing Technology · 2010
Efficiently filtering the noise of traveling wave and extracting the useful traveling wave signal are the keys that realize the railway transmission line traveling wave fault location。Mathematics Morphology is a tool of nonlinearity signal processing,which completely deal with the signal in the time-region,can eliminate all noise and at the same time reserve the merit of overall situation and part character of original signal,simulation results show the mathematics morphology has a good denoising capability.
