基于随机矩阵理论的配电网阵列薄弱性评估系统设计

Weak Point Detection System Design Based on Random Matrix Theory for Distributed Network

基于随机矩阵理论设计了配电网阵列的薄弱性评估系统。依次介绍了工程项目背景和算法理论知识,通过对实际数据的时空联合特性分析,提炼出大数据中的高维指标。所设计的方案已经部署于实际电力系统平台上,服务于巡检、调度等作业。最后通过真实算例对所提方案进行验证,进而提出了命中率和虚警率作为方案的考量指标。

Based on random matrix theory,a system was designed for weak point detection of distribution network. The engineering background and related theories were introduced. Using the spatial-temporal analysis,the feature in the data was extracted in the form of indicator. The approach was validated using field data on certain physical platform for routing inspection and dispatch. Furthermore,hit ratio and false alarm ratio were presented to estimate the designed system.
