Abstract
Selection of proper control techniques and its implementation plays the most important roles for improvement of power quality. In this paper, different control techniques are implemented in the proposed unified power quality conditioner (UPQC) to enhance the power quality in a distribution system. The proposed UPQC is designed with the combination of both shunt and series controller. Shunt controller is used to mitigate the current harmonics, and the series filter is used to mitigate the voltage harmonics in conjunction with hysteresis current and hysteresis voltage controller, respectively. At first, the series part of the UPQC is controlled with UVTG and hysteresis technique based on voltage and after that, unit vector template generation (UVTG), D-Q theory, P-Q theory, and D-STATCOM-based control approach applied for the reference signal generation in the shunt part of the proposed UPQC. Hysteresis control based on current techniques is associated with the four methods for generation of switching signal. The effectiveness of all the controller is verified with simulation using MATLAB/Simulink platform, and a comparative analysis presented and the effectiveness of the D-STATCOM-based control techniques is proved as the best technique for UPQC to improve power quality.
