一种多维电参量的数据拓扑映射建模方法

本发明提供一种多维电参量的数据拓扑映射建模方法、装置、电子设备及计算机可读存储介质。该方法包括：获取低压台区节点的多维电参量时间序列数据并进行预处理；根据用户节点相别信息进行同相分组，形成对应相别下的数据子集；基于数据子集构建各电参量通道下的目标特征向量；基于目标特征向量构造节点间距离矩阵，并构造多维电参量融合距离矩阵；基于距离矩阵设置递增距离阈值序列，形成用于持续同调分析的多尺度拓扑关系结构；计算Betti数、持久条形码和持久图，并基于其统计特征构造拓扑指纹向量；对不同时段或不同时间窗口下得到的拓扑指纹向量进行时间关联分析，输出低压台区的数据拓扑映射模型。本发明能够在统一框架下表征低压台区状态拓扑、用电行为拓扑和负荷承载拓扑，可用于低压台区结构关系表征、一致性分析、异常识别及拓扑演化分析。
