摘　　要：电网中各类敏感负荷投入使用,电能质量要求与日俱增,影响用电设备正常运行的主要电能质量问题是因短路故障造成的电压暂降,为使电网故障得到及时处理,降低经济损失,提升供电可靠性,本文以物联网为技术背景,设计一种电网暂降故障节点智能定位系统。经仿真实验证明,当各种线路上均存在单相对地、相间、两相对地以及三相短路故障种类时,本文系统能够精准定位各种情况下的暂降故障节点,且定位距离偏差较小,具有较好的有效性与实践性。All kinds of sensitive loads in the power grid are put into use, and the power quality requirements are increasing day by day.The main power quality problem that affects the normal operation of electrical equipment is the voltage sag caused by short-circuit faults. In this paper, with the Internet of Things as the technical background, an intelligent positioning system for grid sag fault nodes is designed. Simulation experiments show that when there are single-phase, phase-to-phase, two-phase-to-ground and three-phase short-circuit fault types on various lines, the system in this paper can accurately locate sag fault nodes in various situations, and the positioning distance deviation is small, with good effectiveness and practicality.
