背景技术Background technique

电力线损是电能质量的一个重要指标，各级电力部门都非常重视。及时发现窃电用户和计量故障是电路线损监测的主要内容。目前，电路线损监测主要通过以下方法进行：一方面，通过在用户终端加装计量交流采样装置来进行比较分析，由此发现窃电用户。另一方面，通过人工巡检来发现计量故障。实践表明，此种电路线损监测方法由于自身原理所限，一方面存在采集数据不完整的问题，另一方面其无法整体反映一个区域内的电力线损，导致出现问题时需要逐级查询，由此导致人工成本过高。Power line loss is an important indicator of power quality, and the power departments at all levels attach great importance to it. Timely detection of electricity stealing users and metering faults is the main content of circuit line loss monitoring.

On the other hand, metering faults are found through manual inspection. Practice has shown that this circuit line loss monitoring method is limited by its own principles. On the one hand, there is a problem of incomplete data collection; This results in excessive labor costs.
