Abstract

This paper presents a systematic approach for designing of Static var Compensator (SVC) based damping controllers for damping of low frequency oscillations in a power system. Detailed investigation have been carried out considering two controllers like Power System Stabilizer (PSS) controller and Power Oscillation Damping (POD) controller under variation of mechanical disturbances (Pm) which provides robust performance for single machine infinite bus (SMIB) power system. The realization of the Phillips-Heffron model has been completely and effectively done on comprehensive and user friendly simulink platform. Here, we have designed simplified transfer function block set model to minimize the simulation time because model designed on another domains while simulation internally converts original model to such simplified block diagram model. Eigen value analysis validates the performance of various controllers.Keywords:-FACTS, SVC, PI, PSS, POD, Damping of oscillations.
