近年来,随着电网规模的不断扩大,输电线路长度不断增长,输电线路故障多发,雷击、冰闪、鸟害、污闪、风偏等自然灾害频频引起架空输电线路故障.为了提高输电线路跳闸故障诊断能力,增强线路的安全稳定运行水平,各种故障诊断系统越来越多地应用输电线路.这类智能化技术和设备的应用,显著提高了输电线路故障诊断和故障定位能力,缩短了故障巡线时间,颠覆式地改变了传统的线路故障抢修工作模式,极大提高了一线人员对线路的排障和抢修效率.本文针对一起500kV线路故障实例,应用基于行波定位技术的分布式诊断系统进行故障分析,对该系统在线路故障中的应用进行探究.本文首先介绍了分布式诊断系统的系统架构,然后介绍了该系统的故障定位、故障辨识、雷击检测等功能,最后结合故障实例,讨论故障诊断系统的应用情况,最后对应用效果进行了评估。
