| 摘 要： | 对传统小电流接地系统单相接地故障的选线原理和方法进行了分析,提出一种基于配电自动化系统平台进行单相接地故障定位的新方法.该方法充分利用配电自动化系统的信息资源,构建逻辑空间分析模型和信息融合算法.该算法综合考虑了配电网络中各个节点呈现的电气特征及其在电网拓扑中的分布规律,体现了逻辑空间分析模型中的逻辑"0","1"对结果的等同贡献.文中还对算法的有效性进行了理论推导并导出算法容错能力的评价指标,经理论分析、指标评价和算例证明,该方法有很好的适应性和容错能力.

| Abstract: | Through analyzing various principles of single-phase grounding fault selection in small current grounding power systems,a new method of single-phase grounding fault location based on a distribution automation system is presented,in which a logical space model and an information fusion algorithm are built with the information resources of the distribution automation system.The fusion algorithm synthetically considers electrical characteristics of each node of power networks and their distribution rules in th... |
