Abstract

The modelling, simulation and performance comparison of the power system stabilizer (PSS) and interline power flow controller (IPFC) based damping controller to enhance small signal stability (SSS) enhancement have been presented in this paper. For this reason, a linearized HeffronPhillips model of a single machine infinite bus (SMIB) together with PSS and IPFC is considered. The simulation of the above model is carried out with PSS and IPFC to observe the dynamics in rotor speed deviation. Also, the eigenvalue analysis for the above models are presented to demonstrate the superior performance of IPFC. The comparative analysis is performed with the lack of sufficient damping torque and different loading condition using EMTP-RV and MATLAB/Simulink software. It is observed from the analysis that IPFC provides enhanced SSS performance as compare to PSS.
