摘要
文中提出了一种结合电力系统分析程序、数据库检索方法和模式识别技术自动识别的11kV配电网故障定位方法。该方法采用三相不平衡潮流和故障分析程序,对配电网各节点的故障进行分析生成电压暂降数据库,设计了数据库搜索和模式识别算法,以便配电网在发生实际故障时识别故障位置。利用电力系统EMTDC模拟器对该方法进行了评估和测试。实验结果表明,提出的线性模式识别算法能够识别所研究的11kV配电网的大部分故障区段。
An automatic fault location method for 11kV distribution network is presented in this paper,which combines power system analysis program,database retrieval method and pattern recognition technology.In this method,three-phase unbalanced power flow and fault analysis program are used to analyze the faults of each node in distribution network to generate voltage sag database,and database search and pattern recognition algorithm are designed to identify the fault location when actual faults occur in distribution network.This method is evaluated and tested by using EMTDC simulator of power system.The experimental results show that the proposed linear pattern recognition algorithm can identify most of the fault sections of the 11kV distribution network studied.
