Power Quality Improvement using Repetitive Controlled Dynamic Voltage Restorer for various faults
In this work a repetitive controller has been used in the control system of the DVR [1] to compensate for key power quality problems namely voltage sags, harmonic voltages and voltage imbalances. This control system contains a feed forward term to improve the transient response and a feedback term to enable zero error in steady state. This paper proposes to verify results given for a line to li...
متن کاملVoltage Quality Improvement using Dynamic Voltage Restorer
Power quality is one of major problems in the presence era. It has become importance especially, with the introduction of sophisticated devices, whose performance is very sensitive to quality of power supply. power quality problem is an occurrence manifested as a nonstandard voltage,current,or frequency that results in a failure of end use euipement.One of the major problem deal here is the vol...
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 ...
متن کاملModelling and Simulation of Dynamic Voltage Restorer for Power Quality Improvement
The dynamic voltage restorer (DVR) is used to regulate the voltage at the load terminals from various power quality problems like sag, swell, harmonics, unbalance etc., in supply voltage. This paper presents modelling aspects of several types of Dynamic Voltage Restorer (DVR) working against various voltage sags by simulation in PSCAD/EMTDC. The reference signal for the series connected DVR is ...
متن کاملDesign and Simulation of a Novel Self Supported Dynamic Voltage Restorer (DVR) for Power Quality Improvement
Power quality is one of the major concerns in the present era. The problem of voltage sags and swells and its major impact on sensitive loads are well known. To solve this problem, custom power devices are used. One of those devices is the Dynamic Vol tage Restorer (DVR), which is one of the most efficient and effective modern custom power devices used in power distribution networks. A new cont...
