Implementation of conventional and phasor based power system stabilizing controls for real-time simulation

This paper presents the implementation of three different types of Power System Stabilizers (PSS) anda Static Var Compensator with a supplementary Phasor Power Oscillation Damper (POD) control for real-time simulation. The Klein-Rogers-Kundur model is used as test case and the PSS and Phasor-POD´s performance is evaluated for both large and small disturbances. Modeling is performed in the MATLAB/Simulink environment and is executed in real-time using Opal-RT´s eMEGAsim Real-Time Simulator. The simulation results and the developed model will be used to deploy hardware prototype based on embedded controllers to provide power oscillation damping. Real-time software in the loop (SIL) approach is used for validating developed models as a first logical step towards development of a prototype hardware controller.
