面向对象方法在行波测距系统中的应用

ransmission lines is an important part of power system, its fault would jeopardize the security and stability of power system, an accurate and reliable fault localization can not only save a lot of manpower and material resources, but also reduce the impact on economic and political life. There are fault distance information in the high frequency travelling waves as high voltage transmission lines, according this theory to achieve fault location has been widely studied and applied, its main problem is that the complexity to analysis high frequency transient signal and the diversity structural parameters of lines, ranging accuracy is constrained to some extent. To solve these problems, this paper presents a wavelet-based and object-oriented method to achieve the traveling wave data analysis system. The ranging device based on this analysis system operation show: the mentioned theory and method is correct and effective.
