基于振荡波电压法的电缆局部放电数据分析与管理系统

摘要

基于振荡波电压法，考虑了局部放电信号的入射波形与反射波形时间限制、相似性、时频衰减性等因素，开发了一个电缆局部放电数据分析与管理系统。该系统与现场采集的原始数据兼容，具有定位算法精度高、数据分散性较小的特点，且系统能够实现电缆局部放电信息台账管理、状态评估与风险管理及打印报表等。%Based on the oscillatory wave voltage method, and taking the factors into account such as the time limit, similarity, time-frequency attenuation of incident wave and reflected wave in partial discharge signal, this paper develops an analysis and administration system for cable partial discharge data. The system is compatible with the original data collected from spot, and has the characteristics of high positioning accuracy and low data dispersion, and is able to realize the functions such as the account management of partial discharge informationt, condition assessment, risk management and report printing.
