Abstract

To improve the fault detection and recovery capabilities of distributed distribution networks, a distributed fault recovery method based on island segmentation is proposed. By establishing a fault feature analysis model, an autonomous island system is constructed and optimized using a dynamic distributed linear programming model. The design parameters of fault islands are divided using the branch and bound method, the steepest descent method, and the interior point method. Establish a dynamic parameter analysis model under large-scale uncertainty to achieve fault detection and recovery. The experimental results show that this method can accurately identify fault lines containing distributed power sources, effectively recover fault lines, and solve the problem of complex topology fault recovery.

基于岛屿分区的分布式配电网络故障恢复方法
为提高分布式配电网络的故障检测和恢复能力,提出了一种基于孤岛分割的分布式故障恢复方法。通过建立故障特征分析模型,利用动态分布式线性规划模型构建并优化了自治岛系统。利用分支与边界法、最陡下降法和内点法划分故障岛的设计参数。建立大规模不确定性下的动态参数分析模型,实现故障检测和恢复。实验结果表明,该方法能准确识别包含分布式电源的故障线路,有效恢复故障线路,解决复杂拓扑故障恢复问题。
