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