本文对一条真实的205节点配电线路的两种故障测距方法进行了比较。应用的故障定位算法是基于阻抗和行波的方法。研究算法有一些有意义的差异，研究人员发现有趣的。最重要的是，用于记录设定继电器点和特定采样率下的电压/电流的测量设备的数量和类型。由于在基于故障后阻抗的算法期间电压和电流的基波分量，电压和电流记录器都以低采样率安装。在基于行波的算法中，电压记录器使用高采样率。算法的准确性已被验证的几个模拟故障的研究进行了EMTP-RV软件上的205节点的20 kV真实的径向配电馈线。为了显示每种方法的能力，仿真结果已经提出了在不同的情况下，如故障类型，故障电阻，故障起始角和分布式电源的存在。
In this paper, two fault location methods in a real 205-nodes distribution feeder have been compared. The applied fault location algorithms are impedance and travelling based methods. The investigated algorithms have some meaningful differences which researchers find interesting. Most importantly the number and types of measuring devices for logging the voltage/current at a set relay point and at a particular sampling rate. Due to the fundamental component of voltage and current during a post-fault impedance based algorithm, both voltage and current recorders have been installed with a low sampling rate. In a travelling wave based algorithm, they voltage recorder uses high sampling rate. The accuracy of the algorithms have been validated by several simulated fault studies carried out in EMTP-RV software on a 205-nodes 20 kV real radial distribution feeder. In order to show the capabilities of each method, the simulation results have been presented in different cases such as fault type, fault resistance, fault inception angle and existence of distributed generation.
