Distribution Static Compensator (DSTATCOM) is proposed for compensation of reactive power and unbalance caused by various loads (Sensitive and Non-Linear Loads) in distribution system. Distribution static compensator is based on the VSC principle. A D-STATCOM injects a current into the system to correct the voltage sag, swell and power factor. Distribution Static Synchronous Compensator (D-STATCOM) is an effective measure to maintain voltage stability and improve power quality of distribution system. An LCL filter has been used at the front end of a voltage source inverter (VSI), which provides better switching harmonics elimination while using much smaller value of an inductor as compared with the traditional L filter. A capacitor is used in series with an LCL filter to reduce the dc-link voltage of the DSTATCOM. This consequently reduces the power rating of the VSI. With reduced dc-link voltage, the voltage across the shunt capacitor of the LCL filter will be also less. It will reduce the power losses in the damping resistor as compared with the traditional LCL filter with passive damping. Therefore, the proposed DSTATCOM topology will have reduced weight, cost, rating, and size with improved efficiency and current compensation capability compared with the traditional topology. This paper deals with the modeling and control scheme of D-STATCOM. In this project by analyzing the different control techniques for designing the DSTATCOM & implementing the algorithm which will help in to design the model & working of DSTATCOM in MATLAB/Simulink for the required result.
