INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY Analysis on Topology of DVR Used in Low-voltage Distribution Grid Yanlei Zhao, Chuanxiao Wang , Jingjing Yan School of Electrical and Electronic Engineering, Shandong University of Technology, Zibo, 255049, China [email protected] Abstract Dynamic voltage restorer (DVR) is a series-connected transient voltage compensation eq...

A new technique presents to improve the performance of dynamic voltage restorer (DVR) for voltage sag mitigation. This control scheme is based on cuckoo search algorithm with tree fuzzy rule based classifier (CSA-TFRC). CSA is used for optimizing the output of TFRC so the classification output of the network is enhanced. While, the combination of cuckoo search algorithm, fuzzy and decision tree...

Having electricity with high quality is one of the more important aims in electrical systems. Disturbances in distribution systems can change voltage waveform. There are some methods to prepare high power quality for sensitive loads. In this research we use “Dynamic Voltage Restorer” to compensate the harmful effects of disturbances on voltage. Since power systems fundamentally have complicated...

This paper discusses the design and development of Dynamic Voltage Restorer (DVR) controller for voltage unbalanced compensation using d-q-o transformation technique. The controller in d-q-o coordinates has better performance than conventional controllers. The controlled variables in d-q-o coordinates are then inversely transformed to the original voltages which produced reference voltages to a...
