Micro-DVR - A development platform for DVR and FACDS

This work presents a development platform with reduced power for DVR and FACDS applications and development. The proposed equipment allows testing control algorithms, hardware behavior as well as the strategy applied in the development of the power circuitry. The DVR (dynamic voltage restorer) is one way to mitigate voltage sags and voltage swells, which are a common cause of damage for the industry, because of the growing number of equipment sensitive to the quality of the delivered electrical energy. The same equipment can be operated as a FACDS (flexible alternating current distribution systems) allowing series compensation of distribution lines, as well as power flow control between parallel feeders, as well as an UPFC (unified power flow controller). This paper emphasizes the implementation of a DVR topology and its results.
