Simultaneous Design and Simulation of Synergetic Power System Stabilizers and a Thyristor-Controller Series Capacitor in Multi-Machine Power Systems
Journal Title: روش های هوشمند در صنعت برق - Year 2017, Vol 8, Issue 30
Abstract
Power system stabilizers (PSSs) are usually utilized for damping synchronous generator torque in order to reduce these oscillations by producing complementary control signals for the generator excitation system. In this study, we used a non-linear power system stabilizer based on synergetic control theory and a thyristor-controller series capacitor (TCSC) simultaneously in order to damp electromechanical oscillations and overcome the problems of linear approximation in a non-linear system which limits system stability in a neighborhood of equilibrium. The proposed synergetic combination of power system stabilizers is completely based on a simplified non-linear model of the system. In order to examine the simultaneous effect of these controllers, we investigated the simulation in single- and multi-machine power systems under various turbulences. Simulation results indicated that the simultaneous performance of TCSC and the synergetic power system stabilizer (SPSS) show a high capacity for damping oscillations and improving stability as compared with SPSS and PSS tuned with genetic algorithm (GAPSS) in any non-linear dynamic power system.
