Abstract


This paper deals with Distribution Static Synchronous compensator (DSTATCOM), which aim at the integration of shunt-active filters. The main purpose of a DSTATCOM is to compensate for voltage flicker/imbalance, reactive power, Voltage Sag, voltage swell, negative sequence current, and harmonics. In other words, the DSTATCOM has the capability of improving power quality at the point of installation on power distribution systems or industrial power systems. This paper discusses the control strategy of the DSTATCOM, with a focus on the flow of instantaneous active and reactive powers inside the DSTATCOM. The present work discusses the compensation principle and different control strategies (PI, FUZZY) of the DSTATCOM in detail. The control strategies are modeled using MATLAB/SIMULINK. The performance is also observed under influence of utility side disturbances such as sag, swell, flicker and spikes. The simulation results are listed in comparison of different control strategies and for the verification of results.

Keywords
