摘要

En 中文
This paper describes a methodology based on wavelet techniques for instability analysis in BWR. The Continuous Wavelet Transform and Multiresolution Analysis using Discrete Wavelet Transform were applied for decomposition of the original signal. This method allows to analyze stationary signals and highly non-stationary signals in the time-scale plane. The results using this method were compared with classic method based on Short-Time Fourier Transform. The methodology was tested analyzing two power instability events: Laguna Verde Unit 1 and case 5 of Forsmark stability benchmark. (C) 2006 Elsevier Ltd. All rights reserved.
