摘要
在小电流接地系统单相接地故障特征分析的基础上,结合小波变换和模糊神经网络的特点,提出了适合配网故障后暂态信号分析的小波模糊神经网络模型及算法,应用于小电流接地系统的故障测距。理论分析及大量仿真结果显示此方法是可行的,且具有较好的故障测距性能。
On the basis of analysis on the characteristics of single phase grounding fault occurred in small current neutral grounding system, combined with the characteristics of wavelet transformation and fuzzy neural network, a wavelet fuzzy neural network method and algorithm was proposed and applied for the fault location on non-direct grounding system, which is suitable for the analysis of the post-fault transient state signals in power networks. Theoretical analysis and the simulation results illustrate the efficiency and practice of the method proposed.
