This paper presents a new approach to solve line outage detection (LOD) problem utilizing current phasors obtained from phasor measurement units (PMUs). A new term that is, objective coefficient value (OCV), is introduced utilizing the rank correlation coefficient (RCC) and line outage detection is carried out based on the OCV. Moreover, the effect of bad data (BD) and measurement noises are also considered in the developed mathematical model. Furthermore, it has been proved that the suggested scheme can identify outage of parallel lines (PLs), whereas the existing voltage phasor‐based algorithms fail to do so. Moreover, a new logical index that is, performance improvement w.r.t detection accuracy (PIDA) is introduced to quantify the superiority of the proposed scheme over some existing techniques. The developed algorithm is implemented on IEEE 5‐bus, 14‐bus, 57‐bus, 118‐bus systems, and large‐scale Polish 2383‐bus system. The comparison of test results with some existing methods proves the applicability and brevity of the developed algorithm.

秩相关系数在PMU电流相量检测线路中断中的首次应用

本文提出了一种利用从相量测量单元（PMU）获得的电流相量来解决线路中断检测（LOD）问题的新方法。利用秩相关系数（RCC）引入了一个新的术语，即客观系数值（OCV），并基于该OCV进行了线路中断检测。此外，在开发的数学模型中还考虑了不良数据（BD）和测量噪声的影响。此外，已经证明了建议的方案可以识别并联线路（PL）的故障，而现有的基于电压相量的算法则无法做到这一点。此外，引入了一种新的逻辑指标，即性能改进与检测精度（PIDA），以量化所提出的方案相对于某些现有技术的优越性。该算法在IEEE 5总线，14总线，57总线，118总线系统和大型波兰2383总线系统上实现。将测试结果与现有方法进行比较，证明了该算法的适用性和简洁性。
