摘　　要：通过Matlab建模,分析了小电流接地系统单相接地故障时的特征,提出采用综合选线的方案,以提高选线的准确性。选线装置采用TMS320F2812处理器,满足小波变换对大量数据处理的要求,还提出了故障选线的发展方向。Analyzes the single-phase earth fault characteristics of indirect earthed power modeling, proposes a program of integrated selection device uses TMS320F2812 processor line selection to improve the accuracy of to meet the requirements of large amounts wavelet transform, and the development direction of fault line selection is put forward.
