中文摘要:

低压配电网馈线区段短且分支多，现场情况复杂难以准确进行故障定位，出于对设备投资的考量，无法在每个节点安装故障监测装置，开展低压配电网故障监测装置优化配置方法的研究具有现实意义。文中利用安装在线路分段开关或联络开关处的故障监测装置监测故障电流信息，将边缘计算技术应用于故障定位系统。统计各个馈线区段发生故障时各馈线首端节点的参与频次，依次计算节点参与度。设计综合考虑整体故障监测单元的参与度和监测装置配置均匀程度的优化模型目标函数，考虑经济性约束条件。通过多个算例验证了文中所提出的优化配置方法的正确性和有效性。文中方法可有效确保低压有源配电网故障定位的准确性，提高低压配电网运行的可靠性与经济性。

英文摘要:

The fault line segment location is a difficult problem of the feeders of low-voltage distribution network due to the short line segment length, a large number of line branches and complex field conditions. Moreover, the scheme that deploying a fault monitoring device at each node is impractical due to limited equipment investment. It is of practical significance to study the method of optimal configuration of fault location devices in low-voltage active distribution networks. In this paper, fault monitoring devices installed at the line section switches or tie switches are employed to monitor fault current information, the edge computing technology is applied to the fault location system. And the number of the head end of each feeder line involved in a fault occurring in each feeder section is counted to calculate the node participation degree. The objective function of the optimal monitoring device configuration is built by comprehensively considering the overall participation and the uniformity of the monitoring units, and the economic constraint is considered. The correctness and effectiveness of the proposed method are verified by multiple simulations. The proposed method can effectively ensure the accuracy of fault location in low-voltage active distribution network, and improve the reliability and economy of low-voltage distribution network operation.
