Harmonics plays important role in the function of the power system network. Hence, the harmonics improvement will increase the performance of power system equipment’s. This paper presents the design and implementation of distribution static compensator (DSTATCOM) with the star-delta transformer for analysis of Harmonics in three-phase four wire distribution system in the presence of three-phase Nonlinear-load in the events of single phase, two-phase and three phase tripping. The unit vector template method based control algorithm has been implemented for the control of the proposed DSTATCOM. The proposed test model has been simulated in SIMULINK/MATLAB environment. The simulations results show the effectiveness of proposed algorithm.
