摘要:
在正交匹配追踪(OMP)算法的基础上增加了Jaccard系数以提高其对相似原子的辨识能力，重新构建出更准确的信号以获取故障行波固有频率进行故障测距。在SIMULINK上搭建仿真模型验证表明：在单相接地、两相短路、三相短路等不同的故障类型、不同的故障距离和不同的过渡电阻情况下，改进算法定位精度较高。
Abstract:
Based on the orthogonal matching pursuit (OMP) algorithm, the Jaccard coefficient is added to improve the recognition ability of similar atoms, and a more accurate signal is reconstructed to obtain the natural frequency of the fault traveling wave for fault location. The simulation model built on SIMULINK shows that the improved algorithm has higher positioning accuracy under different fault types such as single-phase grounding, two-phase short circuit and three-phase short circuit, different fault distance and different transition resistance.
