Damping Electromechanical Oscillations using Remote Signal Fed STATCOM.

Abstract

This paper investigates the effects of Static Synchronous Compensator (STATCOM) on electromechanical oscillations damping in a wide area network of power system. It focuses on the use of STATCOM and Phasor Measurement Units (PMU) to damp generators speed deviations and bus voltage profile improvement. The network performances were evaluated without remote centre called Power Oscillation Damper (PDC) serving as input to STATCOM in enhancing the system stability. The case study was mathematically modelled using system parameters in Power System Analysis Toolbox (PSAT) environment where most of the simulations were carried out. Finally, the overall performance of the network was evaluated by nonlinear simulations, and results obtained showed the effectiveness of the use of remote inputs in improving the dynamic stability of the system and provided better damping to the power swings.
