摘要
分析了GIS局部放电中白噪声干扰。仿真实验结果表明,小波分析方法抑制白噪干扰能力强,信号畸变小,能够有效的从白噪干扰中提取局放信号。
The white noise interference in GIS PD is analyzed. Simulative experimental results show that it is strong for the analysis method of wavelet to supress white noise interference,the signal distortion is little and can pick up PD signal from the white noise interference effectively.
