Ubicación de un control de modos deslizantes y PSS’s con el objetivo de amortiguar oscilaciones electromecánicas utilizando el método del residuo y fuzzy

Abstract

The purpose of this document is to determine the location of power system stabilizers (PSS) and sliding mode control (SMC) in order to damp electromechanical oscillations by the residue method. The proposed control is evaluated by performing several simulations on the 39 Bus New England power system and the National Interconnected System of Ecuador. Inter-area and local oscillations are analyzed. A modal analysis is performed on inter-area and local power flow in order to evaluate the effect of the control system numerically. Matrices A, B, C, D are obtained in Power Factory's DigSILENT© software and processed in MATLAB© in order to determine the residue of the oscillation modes with which it is possible to find the tuning and location of the stabilizers power modes in which a sliding mode control is included across the voltage regulators. A comparison is made between the participation factors and the residue method. Finally, the coordination of the power stabilizers is performed through the Fuzzy logic.
