基于自生成小波变换的配电电缆高阻故障精确定位方法

open access: yesGaoya dianqi
高阻故障是配电电缆常见故障形式之一,其准确定位对提升电网运行可靠性具有重要意义。针对传统小波变换中母小波需预设、难以与实际故障信号特征自适应匹配的问题,文中提出一种基于自生成小波变换的高阻故障定位方法。首先利用ATP-EMTP建立电缆分布参数模型,分析高阻故障击穿的波传播特性。其次,以故障波形初始段自适应生成母小波,并进行连续小波变换提取特征频率,实现故障精确定位。仿真结果表明,所提方法平均定位误差仅为0.168%,在鲁棒性、计算效率及采样频率适应性方面均优于传统过零点检测、傅里叶变换 ...

一起特高压输电线路圆柱头悬式瓷绝缘子劣化原因分析

open access: yesDianci bileiqi
使用红外检测技术发现了某特高压交流输电线路圆柱头悬式瓷绝缘子发生异常发热现象,这一发现对于及时诊断和分析特高压圆柱头悬式瓷绝缘子劣化具有重要意义。为了研究劣化机理,分别通过绝缘电阻试验、工频击穿电压试验、抽样试验、瓷件解剖试验、X射线衍射试验和扫描电镜试验,全面评估了劣化样品的电气、机械和材料性能。结果表明,瓷件头部存在微裂纹及水泥胶装层存在大量气孔是造成本次瓷绝缘子劣化的主要原因。本研究不仅为瓷绝缘子的失效分析提供了科学依据,也为制定有效的预防措施和改进策略提供了指导 ...
