The fractal erosion of safe basin in a power system disturbed by a periodical load is studied, and the erosion extent induced by different disturbancevalues is numerically analyzed.
Wavelet multi-resolution analysis method was used to detect de-noising disturbance signal, character valuesof the transient voltage disturbance signal were extracted more precisely.
利用小波多分辨率分析方法对去噪后的扰动信号进行检测,更精确地提取出了暂态电压扰动信号的特征值。
