Özet:

Distribution System consist of different types of loads like linear and nonlinear load. Due to different types of loads, voltage unbalance and other power quality related issues will occur. To overcome this problem, a voltage source inverter based device called distribution static compensator can be used. In this work, an improved voltage controller for distributed static compensator, based on power balancing theory is presented. The improved controller uses only voltage sensors and this controller is developed by considering unbalanced load conditions. Proportional Integral controller is used for maintaining terminal voltage and DC link voltage. The controller is verified for different voltage disturbances such as sag and swell. MATLAB/SIMULINK package is used to verify the controller using simulation. The controller is also verified using Hardware in the loop simulation using DSPACE and results are presented for different voltage disturbances.<
