In this paper, a second order sliding mode control scheme is utilized for outer voltage loop of three-phase fault current limiter-based dynamic restorer (FCL-DVR) instead conventional proportional integral/proportional resonance (PI/PR) controller. The new strategy improves the performance FCL-DVR against distortion. Furthermore, by using proposed robustness controller, can smoothly switch betw...

The stable and precise level of input essential smooth trouble-free operation electrically sensitive loads which are connected at utility side to avoid malfunctions. context, PV-TEG ...

In this paper, a new control algorithm for the dynamic voltage restorer (DVR) is proposed to regulate the load terminal voltage during various power quality problems that include sag, swell, harmonics and unbalance in the voltage at the point of common coupling (PCC). The proposed control strategy is an Adaline (Adaptive linear element) Artificial Neural Network (ANN) and is used to control a c...

Abstract. The design of a Dynamic Voltage Restorer that is suitable for compensating regional voltage sags in 10kV distribution system is introduced in this paper. The design of the main circuit based on cascaded H-bridge, the device for energize DVR and the transformer-less coupled circuit are presented.

today, with attention to increase in sensitive electrical equipments application in distribution networks and their susceptibility to the power quality deficiencies, the protection necessity of sensitive loads against undesirable effects of these disturbances are in focus. so, in this paper voltage sag deficiency and dynamic voltage restorer (dvr) would be introduced as the most prevalent power...

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...
