This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...

Custom power devices such as dynamic voltage restorer (DVR) and DSTATCOM are used to improve the power quality in distribution systems. These devices require real power to compensate the deep voltage sag during sufficient time. An interline DVR (IDVR) consists of several DVRs in different feeders. In this paper, a neural network is proposed to control the IDVR performance to achieve optimal mit...

Voltage sags/swells and harmonics are recurring problems in electric energy distribution systems. In order to solve these issues, several dynamic voltage restorer (DVR) topologies, such as the conventional three-wire DVR, have been proposed literature. Despite its capability of mitigating disturbances, many researchers established that DVR cannot compensate for zero sequence disturbances. this ...

This paper proposes a novel combined device for fault current limiting and dynamic voltage restoring. It consists of a diode bridge superconducting fault current limiter and a dynamic voltage restorer, which both connected together via a common dc link. Interline FCL-DVR system is interlined between two different feeders that connected to a point of common coupling (PCC) in distribution network...
