Caracterización de la Estabilidad Oscilatoria del Sistema Eléctrico Ecuatoriano mediante la identificación de patrones de oscilación a partir de Mediciones Sincrofasoriales

Abstract

The Operador Nacional de Electricidad - CENACE, currently has a monitoring system for phasor measurements, which allows monitoring of an electrical power system through the variables of the voltage, current and angle system. That through of this information it is possible to characterize states of operation that can evolve to a condition of instability or loss of security of the electrical system. On the other hand, there are data that comes from the SCADA system that allows to observe the information of a generation dispatch, to supply the demand of the system. By making use of this data set, it is possible to perform statistical analyzes that provide the Operator with valuable information for making decision. This makes it possible to infer, through a statistical analysis, the presence of low-attenuated oscillations or non-damped (increasing) low-frequency oscillations that would occur under certain operating conditions of the system. This solution would allow preventing situations that could lead the system to partial collapses or total collapse. And on the other hand characterize the normal states in order to give early warnings in situations different from these through the models of risk detection through binary models and techniques such as the ACP and SVM
