| 摘 要： | 目前配电网普遍采用中性点不直接接地的方式（又称小电流系统），配电网中单相接地仍是主要的故障形式，准确可靠的选线问题仍未得到有效解决．采用小波分析和遗传优化神经网络相结合的方法实现接地故障选线．Matlab仿真结果表明，该方法能够实现准确可靠的选线．

| Abstract: | The neutral of distribution network is usually non-direct grounding at present(small current system).In distribution network,phase to ground fault is the primary fault.Selecting the fault line truly and reliably is still a difficult problem.A method of combining Wavelet and GA-BP neural network(NN) is utilized to select the faulty line.The Matlab simulation verifies the effectiveness of the proposed method. |
