摘要
从小波变换的基本理论出发,构造出适于电力系统故障信号分析的基本小波,同时,为了满足电力系统的实时性需求,提出了改进递归小波变换,并利用其进行了鉴别变压器励磁涌流的研究。研究结果表明该方法是可行的。
A mother wavelet suitable for processing transient signals of power system is constructed according to theory of the wavelet analysis.The improved recursive wavelet transform(IRWT) is presented in order to meet the real-time demands of analyzing power system signals. At the same time,IRWT is used to detect the transformer inrush current generated by PSCAD,which is proved both effective and feasible.
