一种面向低压配电网的非侵入故障定位识别方法

The Non Intrusive Fault Localization and Identification Method for Low Voltage Distribution Network

非侵入式负荷监测由于安装成本低、对用户影响小,成为未来低压用户电力负荷监测的重要发展方向。论文基于非侵入负荷分解的原理,提出了一种基于非侵入式的低压配电网短路故障定位方法,构建了低压配电网非侵入式短路故障识别系统,并给出了故障识别的详细步骤,能够实现低压配电网故障类型和故障区域的初定位,如果能够结合低压支线回路的智能电能表,将能够实现故障类型和故障区域的精确定位,此方法可以用于电力用户内部故障快速诊断和排查。

Non intrusive load monitor due to low installation cost, little influence on users, has become an important development direction of low-voltage power load monitoring in the future. Based on the principle of non intrusive load decomposition, presents a method of low-voltage distribution network fault location based on non intrusive, constructs non intrusive fault identification system of the low voltage distribution network, and gives the detailed steps of fault recognition, to achieve the initial location of low-voltage distribution network fault types and fault zone, if can combined with the low voltage feeder circuit intelligent electric energy meter, will be able to achieve precise positioning of the fault type and region, this method can be used for rapid diagnosis and investigation of internal fault of power user.
