متن کاملVoltage Quality Improvement with Neural Network-Based Interline Dynamic Voltage Restorer
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...
متن کاملVoltage Disturbances Mitigation in Low Voltage Distribution System Using New Configuration of Dynamic Voltage Restorer (DVR)
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...
متن کاملFour Leg Voltage Source Converter based Dynamic Voltage Restorer for Power Quality Improvement in Distribution Networks
This paper deals with digital simulation and control of four leg voltage source converter based Dynamic Voltage Restorer(DVR). The control of DVR that injects a voltage in series with a distribution feeder is presented. DVR is a power electronic controller that can protect sensitive loads from disturbances in supply system. It is observed that DVR can regulate the voltage at the load during an ...
