Abstract

The paper presents impact of the Static Synchronous Compensator (STATCOM) on the performance of distance
relay in transmission lines. A typical 400 kV, 300 km transmission system employing STATCOM is modeled using
MATLAB/Simulink. The effect of STATCOM on distance relay for different fault conditions and different fault locations is
analyzed. Simulation results indicate that the presence of the STATCOM in the transmission system significantly changes the
line impedance which is observed by the distance relay to be smaller or greater than the actual line impedance. In that way
the action of the distance relay changes and results in overreaching or under reaching. Based on those results the
performance of distance relay can be found. It can be verified for the transmission line with STATCOM having different
zones are proposed based on this analysis.
