提出了一种基于电力系统阻抗估计的故障测距方法。所提出的方法使用电力系统参数，在主变电站和主辐射的末端节点处的可用测量。该方法在IEEE 34节点试验系统中进行了验证，其中考虑了单相接地、相间和三相故障，故障电阻在0和40 Ω之间。绝对误差已被用来评估所提出的方法的性能。提出的故障定位器是有用的，以改善电力系统的连续性指标，通过确定故障节点。
This paper presents a fault location method based on the power system impedance estimation (MBM). The proposed methodology uses the power system parameters, the available measurements at the main power substation and at the end node of the main radial. The approach is validated in the IEEE 34-nodes test power system, where single phase to ground, phase to phase and three phase faults and fault resistances between 0 and 40 Ω were considered. Absolute error has been used to evaluate the performance of the proposed methodology. The proposed fault locator is useful to improve the power continuity indexes in power distribution systems, by the determination of the faulted node.
