عنوان انگلیسی A New Topology for Interline Dynamic Voltage Restorer Based on Direct Three-Phase Converter
چکیده انگلیسی مقاله In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology has two direct three-phase converters which have been connected with each other by a common fictitious dc link. Each of the two converters can operate as rectifier or inverter. The converters can directly connected to the grid via used dual-purposed switches and take required power for compensation from it. As a result, unlike conventional topologies, the dc link capacitor and energy-storage elements can be eliminated. Therefore this topology is able to compensate the voltage for any long time interval. Also this topology in Comparison with conventional topology of IDVR, has less volume, weight and cost due to the elimination of energy-storage elements. In addition to compensation voltage under balanced and unbalanced disturbances, the prominent feature of this structure is compensating voltage under very deep voltage sags and power outages. Unlike the conventional topology, the capability of compensation is independent of the power flow and the power factor of each grid. The performance of the proposed IDVR topology is validated by computer simulation with PSCAD/EMTDC software.
