摘要
提出了一种基于小波变换的小波信息熵,并利用其构造设备状态检测指标计算方法,将这种状态检测方法应用到电力机车主整流器故障检测中。通过各种不同故障状态仿真实验分析,表明这种方法是有效的,同时具有较强的抗干扰性。
The paper presents the wavelet information entropy based on wavelet transform,and constructs a state detection target calculation method by making use of the entropy.The method is applied in electric locomotives main converter fault detection.After many simulation experiments analysis with different converter fault states,the results show that the method is effective and anti-interferential.
