摘　　要：文章对计算机智能集中供电系统的负载波形进行了小波变换分层分析,利用其各层系数及能量比值,对冲击性整流负载和一般电力负载电流波形进行分类,用计算机自动区分负载类型。Electrical load waveform in centralized power supply system was analyzed and processed with wavelet analysis. Through factor of each layer and energy ratio, impact rectified load and common load were sorted. Type of load is distinguished by computer.

关 键 词：小波变换 冲击性整流负载 能量比值
