Abstract

The Distribution Static Compensator (DSTATCOM) is mainly used for compensation of load in low voltage distribution system. The study proposes a Hybrid DSTATCOM topology that consists of a three-leg VSI with neutral clamped split capacitor to compensate unbalanced and non-linear loads. The scheme is employed with a series capacitor along with the interfacing inductance and a shunt capacitor. This reduces the required DC-link voltage and consequently reduces the voltage stresses on DC-link capacitor, while the shunt capacitor absorbs switching frequency harmonic components on supply side. The reference currents for the proposed hybrid DSTATCOM have been derived by using Synchronous Reference Frame Theory. The performance of proposed topology is verified using MATLAB/ SIMULINK.
