| 摘 要： | 通过小波变换理论的研究,小波变换对于电力变压器励磁涌流和内部故障电流的鉴别非常有效。使用仿真软件Matlab中的Simulink模块仿真出电力变压器的励磁涌流和内部故障电流,并通过Mallat分解算法分别进行小波变换。实验表明,这两种电流的小波变换结果的细节部分有很大的不同的特征,可以使用在变压器继电保护中。

| Abstract: | The wavelet transform is a powerful tool in distinguishing current of the power transformer inrush and internal fault.The paper does the wavelet transform of differential current signals in the power transformer which is simulated in Simlink of Matlab software. The results of experimentation show that there are significant differences between the two signals, method of distinguish can be used in relaying of power transformer. |
