• 摘要： 零序故障是中压配网中一种常见的故障，为提高中压配网的供电可靠性， 本文推广一种智能型零序故障录波及综合诊断装置，利用主要是利用人工神经 网络（ANN）和专家系统（ES）融为一体的神经网络专家系统。零序故障录波 及综合诊断系统可完整捕获故障发生前后所有零序信号的录波数据，利用这些 数据即可对零序故障进行在线诊断及分析，从而大大减轻监控人员劳动强度， 提高供电可靠性、安全性。
• Zero sequence fault is a common fault in medium voltage distribution net. in order to improve the power supply reliability of medium voltage distribution net.in this paper, an intelligent zero sequence fault recording and comprehensive diagnosis device is popularized, which mainly USES artificial neural network (ANN) and expert system (ES). The zero-sequence fault recording and comprehensive diagnosis system can fully capture the recording data of all the zero-sequence signals before and after the occurrence of the fault, which can be used to diagnose and analyze the zero-sequence fault online, thus greatly reducing the labor intensity of monitoring personnel and improving the reliability and safety of power supply.
