| Abstract: | A new parallel-type dynamic voltage restoration control device is proposed with analysis of its operating principle. Compensation algorithm and control method are given to deal with typical voltage quality problems occurred in power system, such as continuous voltage sag compensation, efficiency of DC voltage, and low-pass filtering. Based on PSCAD/EMTDC simulation software, simulation model for a parallel-type dynamic voltage restoration and regulation device is established, simulation results validates the correctness and validity of the proposed main circuit topology and control strategy. |
