Abstract :
In this paper, after an overview of transmission line series compensation, we review series-compensated line protection challenges, that include voltage inversion, current inversion, and distance estimation errors. We then present modern solutions to improve directional, distance, and differential element operation on series-compensated lines. Later we provide relay setting guidelines. Finally, we present and discuss several cases of protection scheme operation for actual faults.
