  1. This paper researches the non - direct - grounded system fault detection from software arithmetic view, whose main content is as follows : the paper analyses the system running characters before and after fault. and the paper analyses the fault transient signal and fault steady signal and all parts in fault steady signal after the single line - to - earth fault occurs, and discovers the fault laws and appearance of fault signal. the analyzing of the fault laws and fault phenomenon of non - direct - grounded system all above is the base of analyzing arithmetic

    本文針對小電流接地系統選線的問題,從軟體演算法的角度進行了研究,主要內容如下:對小電流接地系統故障前和故障后系統的運行特點進行了分析,並且對小電流接地系統發生單相接地故障后,故障暫態信號、故障穩態信號以及故障穩態信號的各種成分進行了深入的分析,找到了故障的規律以及其故障信號的表現形式,為對各種演算法的分析比較打下了基礎。
  2. Judging by the different magnitude and direction of the wavelet packet coefficient modular maximum, we can select the single phase - to - earth line. the method using wavelet singularity detection theory to extract the fault time is discussed. a fault distance measurement algorithm combining wavelet analysis used for separating the character from the transient fault signal with artificial neural networks used for the nonlinear approximation from the transient character to fault distance is presented

    論文提出利用各個出線零序電流在頻帶上小波包系數模極大值的方向和大小的不同來實現故障選線,討論了利用小波分析的奇異性來判斷故障啟動時刻,提出將小波分析和人工神經網路結合,利用人工神經網路的非線性逼近能力,實現故障暫態量到故障距離的非線性映射,完成測距。
