Power Quality Improvement Using Dynamic Voltage Restorer
Journal Title: Bonfring International Journal of Power Systems and Integrated Circuits - Year 2019, Vol 9, Issue 1
Abstract
One of the important in a power system study is a power quality improvement. It will be important now due to preface the discrete industrial devices and sensitive loads. The main issues in a power quality are voltage sags and swells at the distribution side. There are many different methods available to defect voltage sags and swells; the most popular methods is DVR (Dynamic Voltage Restorer). The DVR is a series compensating device, it is mainly used in low voltage and medium voltage application. The new configuration of DVR has been proposed using PI (Proportional Integral) -controller and PID (Proportional Integral Derivative) -controller and also THD values of PI (Proportional Integral) and PID (Proportional Integral Derivative) controllers are compared and it is conclude that total THD in PID (Proportional Integral Derivative) controller is better than PI (Proportional Integral) controller, which compensates voltage sags and swells during a single phase fault. Simulation results are carried out with MATLAB/SIMULINK to verify the performance of the proposed model.
