电力系统故障录波数据分析

Power System Fault Recorder Data Analysis

电力系统故障录波数据是电力系统故障分析和保护动作判据的重要依据。本文提出了据电力系统故障录波数据完善了频率分析、谐波分析、故障定位的数学分析方法。采用java编程语言完成部分过程的编制工作。同时针对目前双端测距存在的伪根问题,提出了一种新的求解过程。

The power system fault recorder data provides the important basis for fault analysis and protective operating criterion. The paper improved frequency measurement mathematical analysis algorithm and harmonic analysis mathematical analysis algorithm as well as fault location mathematical analysis algorithm by use of those data. Using java programming language as development tools and accomplish some function. At the same time, the paper proposes a new solving process aiming at false roots in two-terminal faul...
