摘要
通过介绍行波测距单端测距的原理以及行波的反射机理,阐述了单端行波测距的扩展模型,并结合原理及扩展模型分析了源霸二线跳闸后的XC-21行波测距装置采集到的录波波形,分析出故障点位置,并与实际故障点进行比较得到很高的测距精度。
This paper introduced the principle and reflection mechanism of single-ended traveling waves fault loca-tion,as well as the expand model of single-ended traveling waves fault location.The actual fault location gathered by XC-21 of Yuan-Ba 2nd power line was analysed by the principle and the expand model expounded above.Compared with the actual fault location,the result analyzed in this paper is more accurate.
