摘要
This paper presents the technical aspects of designing a Dynamic Voltage Restorer to meet the stringent requirements of voltage dips mitigation with respect to the magnitude of voltage dip, fault duration, permissible fine voltage deviations and response time. An introduction to the IGCT technology based on latest transparent anode GTO (T-GTO) and gate technology is given. The performance of the DVR based on digital simulations is discussed, Pc description of a hardware based real time simulator model for performance assessment: of DVR in voltage dips mitigation is presented. The results of the real time simulator are compared with the digital simulations. Finally, control and protection concepts for the DVR are highlighted.
