摘要
针对调度自动化系统网络拓扑检测辨识存在的不足,挖掘系统基础数据之间的内在联系,提出一种基于量测平衡指标和设备状态相似度寻优的支路与母线连接关系辨识方法,该方法建立在错误量测检测、辨识及修正的基础上,通过分析支路与母线的关联关系,定义支路与母线关联关系岛,基于岛内各支路量测满足平衡关系的特征,通过搜索使岛内各节点量测平衡指标合格并与实际采集的设备状态具有尽可能高的相似度的支路母线连接关系,给出辨识结果。仿真分析和实际应用证明该方法的有效性。
A new identification method of connection relationship between branch and bus based on optimizing of the measurement balance index and equipment state similarity in power grid is proposed to solve the deficiency of the detection and identification of network topology in dispatching and controlling system of power grid and to find the internal connection between basic data in the system. Measurement detection, identification and correction are used for the method. Through the analysis of the relationship between the branch and the bus, an island of the relationship between the branch and the bus is defined. Based on the fact that the branch measurement on the island meets the characteristics of balanced relationship, and through the search of relationship between branch and bus that makes measurement balance index of each node on the island qualified and have as high as possible a similarity with the actual collected equipment status, the identification results are given. The effectiveness of the proposed method is demonstrated by simulation analysis and practical application.
