a new control algorithm for dynamic voltage restorer (dvr) to improve power quality and voltage in distribution systems
abstract: one the most important problems in recent sensitive loads is the quality of voltage. for this challenge custom power devices are used in distribution systems. dynamic voltage restorer (dvr) is a custom power device that improves voltage, decrease power distortion, filter harmonics and balance distributed generations (dgs) with low voltage distribution system. in this paper, a new algo...
متن کامل"SRF theory revisited" to control self supported dynamic voltage restorer (DVR) for unbalanced and nonlinear loads
In this paper a fuzzy controller based DVR is proposed for the protection of the sensitive unbalanced nonlinear loads from sag/swell, distortion, and unbalance in supply voltage is achieved. A simple generalized algorithm based on basic synchronous reference frame theory has been developed for the generation of instantaneous reference compensating voltages for controlling a DVR. This novel algo...
متن کاملA New Topology for Interline Dynamic Voltage Restorer Based on Direct Three-Phase Converter
In this paper, a new topology for Interline Dynamic Voltage Restorer (IDVR) is proposed. This topology contains two direct three-phase converters which have been connected together by a common fictitious dc-link. According to the kind of the disturbances, both of the converters can be employed as a rectifier or inverter. The converters receive the required compensation energy from the gird thro...
