说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)
