摘要
传统的各种故障选线方法通常利用接地故障产生的某一部分的信息进行处理,选线的精度不高,难以满足现场运行的要求。为此,通过对各种故障信息进行综合分析、融合处理,综合各种故障选线方法,提出故障线路模糊识别技术,采用该技术可减少干扰信号的影响,消除单一保护方法的固有缺陷,提高故障检测的精度和鲁棒性。
Traditional single fault detection methods using only some part of ground fault information have poor reliability. and are unable to meet the requirement of field running. Hence information fusion technique is introduced and applied in fault feeder detection to fuse all kinds of fault information and integrate various fault detection methods. Technique for fault feeder identifying with fuzzy analysis is developed, which can reduce the impact of interference signal, eliminate the inherent shortcomings of the single protection, thus can detect the fault feeder with higher precision and robustness.
