AI Technical Summary
Technical Problem
The accuracy of power grid fault diagnosis in existing technologies is low, leading to frequent electrical fire accidents.
Method used
By acquiring historical power operation data of the power grid, data processing and preprocessing are performed using topology tags to generate standard data sequences. Fault diagnosis is then performed based on residual current and standard preset thresholds. Combined with the associated data of electrical equipment and environmental parameters, the fault type and level are determined, thus achieving accurate fault diagnosis.
Benefits of technology
It improves the accuracy and precision of power grid fault diagnosis, reduces fire risk, shortens fault diagnosis time, improves fault repair efficiency, and reduces manual intervention.

Abstract
本申请涉及一种电网故障诊断方法、装置、计算机设备和存储介质。该方法包括：获取第一周期内电网的历史电力运行数据，根据历史电力运行数据确定第二周期内电网对应的多个标准数据序列，在检测到电网的当前电力运行数据中包括至少一个剩余电流的情况下，根据各剩余电流和至少一个标准数据序列对应的标准预设阈值进行故障诊断得到电网的故障诊断类型，其中，历史电力运行数据为具有拓扑标签的电力运行数据，剩余电流为电网中目标回路的剩余电流。采用本方法能够基于获取到的多个标准数据序列来实现电网故障诊断，提高电网故障诊断结果的准确性。
