The design and implementation of a dynamic voltage restorer (DVR) is presented in this thesis. The proposed DVR can restore the end-user voltage to its normal level by rapidly injecting a compensating voltage onto the power line against the upstream power disturbances. The control algorithm uses the concept of reference voltage tracking method. Based on the electric circuit theory, the filter of the DVR is also analyzed. Besides, performance of the proposed method is simulated and compared with other different control methods by using Matlab-simulink/PSB. The results show the effectiveness of the proposed method. A 2.18 KVA DVR prototype is implemented to verify the performance of the proposed method.
