Abstract :
This paper presences analytical and simulation results of the application of distance relays for the protection of transmission employing Static Synchronous Series Compensator (SSSC). Firstly a detailed model of the SSSC and its control is proposed and then the situation is studied analytically, where the errors introduced in the impedance measurement due to the presence of SSSC on the line are analyzed. The simulation results show the impact of SSSC on the performance of a distance protection relay for different fault conditions; the studies also include the influence of the operational mode of SSSC, its location on the transmission system and fault resistance. The complete digital simulation study using the full 48-pulse GTO-SSSC model. The digital simulation is performed in the MATLAB/Simulink software environment using the Power System Blockset (PSB).
