This study introduces a fault location technique for three-terminal series-compensated untransposed parallel transmission lines utilizing the three terminals’ synchronized data. The proposed technique is applicable for short or long lines as distributed parameter line model is employed and the potential couplings are considered. The fault location for both uncompensated line sections is obtained adopting previously introduced fault location technique. The faulty phases are required initially to be recognized for series-compensated transmission line. The adopted fault location technique for series-compensated line section is derived based on the resistive nature of the fault impedance. The obtained fault locations for each line section are compared with each other to distinguish the faulty branch and obtain the fault location. DIgSILENT Power Factory and MATLAB programs are utilized for simulation studies and required calculations. The obtained results prove the efficacy of the introduced technique.

基于PMU的三端并联串联补偿线路故障定位技术

本研究介绍了一种利用三端同步数据对三端串联补偿未换位并行传输线进行故障定位的技术。所提出的技术适用于短线或长线,因为采用了分布参数线模型并考虑了潜在的耦合。两个未补偿线段的故障定位均采用先前介绍的故障定位技术获得。最初需要识别出故障相位,以用于串联补偿的传输线。基于故障阻抗的电阻特性,推导了采用串联补偿线段的故障定位技术。将获得的每个线段的故障位置相互比较,以区分故障分支并获得故障位置。DIgSILENT Power Factory和MATLAB程序用于仿真研究和所需的计算。获得的结果证明了引入技术的有效性。
