Implemention of distribution energy source as a compensator based on power balance control algorithm

This paper represents a method for evaluating the reference current for the Distribution Static Compensator (DSTATCOM) using power balance control technique under static and dynamic conditions has been discussed. In this paper, three phase three wire VSC (Voltage Source Converter) based DSTATCOM is used for power factor correction, voltage regulation at point of common coupling, load balancing of non linear load. The proposed algorithm is simulated in MATLAB environment using SIMULINK and Sim-Power System (SPS) toolbox. A hardware prototype of DSTATCOM has been developed using dSPACE DS1104 R&D controller having TMS320F240 as slave DSP. Both MATLAB based simulation and hardware test results are presented under steady state and dynamic conditions. It is found that the developed algorithm is effective for improving various power quality features such as unity power operation, harmonic compensation and load balancing.
