Modelamiento y simulación de equipos tipo D-FACTS de potencia en serie para sistemas de distribución

Abstract

This article presents a study on a synchronous static compensator in series for distribution (D-SSSC). The D-SSSC allows to control the flows of active power and the flow of reactive power in the distribution lines of the system. The simulation of a D-SSSC in an electrical distribution system was made by the MATLAB-Simulink programming environment for two models: model 1, a voltage source in the primary winding connected in series to the secondary winding of a transformer and model 2, a voltage source coupled to an impedance in series to the distribution line. For both models, the voltage magnitudes correspond to 10% and 5% of the nominal voltage of the main network to which the electrical distribution system is connected. The simulations were performed on an unbalanced radial system typical of distribution networks. The results of the simulation show the ability of the equipment to control the voltage profile; the total system losses are also obtained as a function of the voltage source of the D-SSSC angle, the voltage in the D-SSSC bar is also obtained as a function of the voltage source of the D-SSSC angle and the operating curves of the powers P and Q.
