摘要
通过搭建试验平台模拟建筑物低压供配电线路中的故障电弧,分析故障电弧特征,提取出三种表征故障电弧的特征量,包括各周期采样点平均值、波形斜率和小波高频系数。应用MATLAB模糊工具箱,采用模糊逻辑推理的方法将三种判据融合,建立故障概率判定系统。
By building experimental platform to simulate the fault arcing in building low-voltage distribution lines,and analyzing the characteristics of fault arcing,extracted 3 characteristic parameters,which included the mean of sampling points per cycle,waveform slope and high-frequency coefficient of wavelet.Utilizing the fuzzy toolbox in MATLAB,fused 3 parameters by fuzzy logic method,and built fault probability access system.
