Parametric sensitivity analysis of series compensated transmission lines protection

摘要

In this paper, it is presented the performance evaluation of series compensated transmission lines distance protection. In order to do so, a wide variety of faults was simulated in a 500 kV/60 Hz series compensated transmission line 400 km long using the software ATP/ATPDraw. The distance protection functions was implemented through the positive sequence voltage polarized mho characteristic. Its performance was evaluated by using parametric sensitivity analysis, thereby only one parameter value changes at a time, providing a more comprehensive understanding of the relationship between each parameter and the performance of the protection.
