基于BP模型的城市配电网中性点小电阻接地系统阻值的研究

Research on Little Resistance Grounded Neutral System of City Distribution Network Based on BP Module

分析 10kV城市配电网中性点经电接地时系统发生的变化在单相接地故障的稳、暂态电量变化规律的基础上 ,利用BP模型的优点 ,提出采用人工神经网络中的BP模型进行中性点接地电阻阻值的确定 ,最后通过算例验证了可行性。

This paper discusses the little resistance grounded neutral system of 10 kilovolt city distribution network,analyzing the regularity of the stable and transient habitus when there is a single phase grounded fault.The authors propose a method,called artificial neural network BP module,to calculate the value of grounded resistance,and give some calculating examples to prove its feasibility.
