    摘要: 本文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,提出了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,定义了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了该方法的有效性。 A new identification method of connection relationship between branch and bus based on opti-mizing of the measurement balance index analysis and equipment state similarity in power grid is proposed to solve the problem of detection and identification of network topology in dispatching and controlling system of power grid. Measurement detection, identification and correction are used for the method. Through the analysis of the relation between the branch and the bus, the relation between the branch and the bus is defined. Based on the fact that branch measurements inside an electrical island satisfy a balanced relationship, through the search of relationship between branch and bus, the measurement balance index of each node is qualified and has a most similar bus-branch relationship as actual equipment status and the identification results are given. The feasibility and effectiveness of the proposed methods are demonstrated by simulation analysis and practical application.
