Abstract

Dynamic voltage restorer (DVR) is a protecting device for sensitive loads which compensates grid voltage fluctuations. Although using fault current limiting devices (FCL) is a method of protecting loads and electrical networks against short circuits. In recent years, some methods have been proposed to combine these two devices to reduce the cost of converters and use the benefits of each device simultaneously. A new topology and control method to combine a DVR and an FCL is presented in this paper, which with just adding a switch to the conventional DVR, the FCL performance will be available for the network. The FCL-DVR has been developed to provide excellent dynamic performance and faster response time to network failures while maintaining appropriate reliability and a low converter cost. The performance ability of the proposed device is investigated by simulation results.
