Enhancement of Power Quality in Distribution System with Reduced DSTATCOM Voltage Rating

چکیده
In power distribution network, distribution static compensator (DSTATCOM) is used for enhancing power quality. This paper investigates the application of DSTATCOM with non-stiff source connected to distribution network to enhance power quality. The model discussed in this paper is designed to have reduced DC-link voltage rating without compromising compensation capability when non-linear loads are connected to distribution network. This model uses a series capacitor along with interfacing inductor and a shunt filter capacitor. Having this reduced DC-link voltage, the average switching frequency of insulated gate bipolar transistor (IGBT) switches of DSTATCOM reduces and thus reducing switching losses in inverter. Simulation studies are carried out using matlab/simulink and the results shown proves the performance of the system when non-linear loads are connected.
