摘要
有效地抑制电磁干扰是局部放电检测技术中的关键技术之一。针对局部放电检测中的周期性干扰和白噪干扰,提出几种可行的小波变换方法进行抑制。理论分析和仿真实验结果表明,小波分析能有效抑制周期性干扰和白噪干扰,从而提取局部放电脉冲。
Effectively restraining electromagnetic interferences is one of the most important technologies in monitoring PD. Several kinds of wavelet transform ways are applied to restrain the periodic interferences and white noise. Theoretical analysis and results of simulation show that wavelet analysis are effective in restraining the periodic interferences and white noise to extract the PD pulses.
