基于云边协同的输电线路状态评估预警系统、方法及设备

本发明涉及输电线路状态监测与故障定位技术领域，公开一种基于云边协同的输电线路状态评估预警系统、方法及设备。系统包括多个边缘监测终端和云端状态评估预警平台。云端根据可调用波形记录和线路节点拓扑确定候选故障区间、当前定位结果层级及目标节点；根据接收开始信息、接收结束信息及是否形成可调用波形记录确定目标节点对应波形记录的接收处理状态，在接收中或接收完成但尚未形成可调用波形记录时保持故障事件开启；满足初步闭合条件且当前可调用波形记录支持至少一种定位路径时，选择定位路径并生成定位结果和预警信息。本发明可降低关键波形仍在传输或处理时故障事件提前闭合的风险。
