摘要
基于分形理论 ,建立了描述局部放电脉冲波形的随机模型 ,提出用分维尺度变化量为特征识别局部放电信号。
Based on the fractal theory, a random model to describe the partial discharge pulse waveform is established, and the fractal dimension ruler variable is introduced to extract the characteristic from PD signals. The experimental results and analysis show that the fractal dimension ruler variable has a higher sensitivity compared with fractal dimension as a practical feature to recognize PD signals.
