Modelamiento y análisis de pequeña señal de un generador de inducción y un STATCOM conectados a un sistema de potencia

Abstract

This paper presents the modeling and small-signal analysis of an induction generator (IG) and a static synchronous compensator (STATCOM) connected to an inÞ nite bus bar, representing a power system, the IG is modeled as Þ fth-order system and is coupled to a STATCOM is studied as a model of Þ rst order. The dynamic behaviorwas simulated and compared using MATLAB/ Simulink, two conditions of disturbance: a variation in the torque of the machine and a variationin the inÞ nite bus bar voltage because of a failure at this point. The responses obtained by the software show that the compensator acts appropriately counteracting power and voltage variations. Significantly, it must add a stage of tuning parameters to improve the responses.
