摘要

在输电线路中安装统一潮流控制器(UPFC)既影响电流信号的暂态分量,也影响电压信号的稳态分量。在这种情况下,传统的距离继电器难以保护这种补偿线路。提出了一种基于叠加原理的UPFC补偿线路快速准确的故障检测、分类和分段识别技术。在这项工作中,电流信号的叠加分量作为特征来执行检测和分类任务。在故障区段识别中,采用电压和电流叠加分量的方法。通过EMTDC/PSCAD在230 kV UPFC补偿双机系统上生成数据,对所提出技术的性能进行了大量测试用例评估。实验结果表明,采用该保护方案可以快速、准确地对线路中点安装UPFC的输电线路进行故障检测、分类和故障区段识别。

Superimposed Component-Based Protection Scheme for UPFC Compensated Transmission Lines
The installation of unified power flow controller (UPFC) in a transmission line affect the transient as well as steady-state components of the current and voltage signals. In such situation the conventional distance relays find difficulty to protect such compensated lines. This paper presents a fast and accurate fault detection, classification and section identification technique for a UPFC compensated line based on superimposed principle. In this work, the superimposed components of current signals are taken as features for performing the detection and classification task. For fault section identification, the voltage and current superimposed components are used together. Performance of the proposed technique is assessed for numerous test cases by generating data on a 230 kV UPFC compensated two machine system through EMTDC/PSCAD. The obtained results clearly show that using the proposed protection scheme fast and accurate fault detection, and classification as well as fault section identification can be accomplished in transmission lines installed with UPFC at the mid-point of the line.
