Prony analysis

Abstract

"This thesis mainly concentrates on improving the performance of power system stabilizers (PSS) _using Prony analysis. The method of evaluating the performance of the PSS using Prony analysis is discussed. This method also helps in finding out the dominant modes that can be damped further.

Two methods of improving the performance are discussed (i) retuning the complete PSS and (ii) adding an additional phase compensator in cascade with an existing PSS to improve damping of specific modes. The pros and cons of each method have been studied. The latter method is chosen because of its inherent advantages.

The proposed method is tested on two test systems namely, a 2-area system and the WSCC 3-machine system. The choice of the systems was based on the fact that both of them consisted of multiple machines and both systems, when perturbed, exhibited oscillations that can be analyzed using Prony analysis.

The simulations are carried out in PSCAD and the ring-down data obtained is used in MATLAB for Prony analysis. Linear system analysis is performed using a commercially available MATLAB toolbox"--Abstract, page iii.
