Sintonización adaptativa de estabilizadores de sistemas de potencia en tiempo real utilizando tecnología de medición sincrofasorial

Abstract

The operation of modern electrical systems presents complex operating conditions and increasingly prevalent uncertainty factors due to the presence of various sources of generation and variable loads. Situation that can promote low-frequency oscillations, which are generally dampened by the power system stabilizer (PSS) itself, which presents a static adjustment, which may not provide enough damping to operating scenarios. Thanks to the fact that currently a power system mostly has monitoring of the dynamic conditions of the network, it is interesting to supply local and global information of the event to the controller. These signals allow dynamics to be tracked in real time, thus becoming a valuable source of information. Based on the aforementioned, this thesis presents a novel methodology that starts from the data of the oscillatory characterization of the electromechanical modes given by the SEP operating point, which properly processed allow to develop an adaptive scheme for adjusting the parameters of PSSs considering the operating point of the system obtained from the measurements of the WAMS system, thereby establishing the damping control strategy of the low frequency oscillations of the power system.
