Description: a transmission line fault location model which is based on an Elman recurrent network
(ERN) has been presented for balanced and unbalanced short circuit faults. All fault situations with
different inception times are implemented on a 380-kV prototype power system. Wavelet transform
(WT) is used for selecting distinctive features about the faulty signals. The system has the advantages of
utilizing single-end measurements, using both voltage and current signals. ERN is able to determine the
fault location occurred on transmission line rapidly and correctly as an important alternative to standard
feedforward back propagation networks (FFNs) and radial basis functions (RBFs) neural networks.

Description: 本文利用小波以及小波包在数字信号处理中表现出来的优势，将其应用到变换域通信(TDCS)中。针对基于傅里叶变换估计方法无法对非平干扰进行有效估计的缺点，于是小波技术被应用于谱估计中。作为TDCS通信前端的频谱感知阶段所应用的数学工具，进行频谱感知，小波变换可以确定干扰所在频段以及创建小波基函数，用于数据传输。并且将其与其他变换方式的应用场合以及性能进行对比。并且针第二代小波良好的数据压缩性能，拟将其应用于TDCS中，对干扰频谱进行进一步压缩-The article utilized the advantages of wavelet and wavelet packet synthesis applying in the digital signal processing domain, and applied it into the Transform Domain Communication System (TDCS). To composite the shortcomings in Fourier Transform in non-stationary noise, wavelet transform are introduced. As a mathematical tool before transformation, wavelet transform will sensing the environment, locate the interference and create a fundamental modulation waveform（FMW）。Comparison with other kinds of transforms is made in this article as well. As the same time, the second generation wavelet has a good performance in data comprising, we could consider utilizing it into further lifting in the quality of the sensing period.

Description: 小波变换(wavelet transform，WT)是一种新的变换分析方法，它继承和发展了短时傅立叶变换局部化的思想，同时又克服了窗口大小不随频率变化等缺点，能够提供一个随频率改变的"时间-频率"窗口，是进行信号时频分析和处理的理想工具。它的主要特点是通过变换能够充分突出问题某些方面的特征，能对时间(空间)频率的局部化分析，通过伸缩平移运算对信号(函数)逐步进行多尺度细化，最终达到高频处时间细分，低频处频率细分，能自动适应时频信号分析的要求，从而可聚焦到信号的任意细节，解决了Fourier变换的困难问题，成为继Fourier变换以来在科学方法上的重大突破。(Wavelet transform (WT) is a new transform analysis method. It inherits and develops the idea of localization of short-time Fourier transform and overcomes the shortcomings that window size does not vary with frequency. It can provide a frequency-dependent The Time-Frequency window is ideal for time-frequency analysis and processing of signals. Its main feature is that by transforming some features that can fully highlight some aspects of the problem, the localization of the time (space) frequency can be analyzed, and the signal (function) can be gradually and multi-scale refined by the scaling operation, finally reaching the high frequency Time subdivision, frequency subdivision at low frequencies, can automatically adapt to the requirements of time-frequency signal analysis, which can focus on any details of the signal to solve the difficulties of Fourier transform has become a major breakthrough in the scientific method since Fourier transform.)
