Study on Compensation of Voltage Sag and Voltage Swell by Using DVR (Dynamic Voltage Restorer)
2018 International Conference on Current Trends towards Converging Technologies (ICCTCT), 2018Significant feature for electrical engineering is quality of power in modern days. Due to growing use of solid state, non-linear, power semiconductor switching devices power quality issues are formed. A power quality crisis refers to the problems that are cause by the increase of a non standard voltage or current or frequency.

A Generalized Voltage Compensation Strategy for Mitigating the Impacts of Voltage Sags/Swells
IEEE Transactions on Power Delivery, 2005Dynamic restoration of load voltage achieved through the application of voltage-injection technique is considered. The injected voltage is generated from a voltage-source-inverter-based series compensator. It is shown that during a voltage sag, the restoration process almost inevitably requires the injection of energy from the compensator to the ...

Optimization of voltage sag/swell using dynamic voltage restorer (DVR)
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016The most interesting issue for electrical engineers is power quality/power quality improvement in modern era. Power quality is the most noticeable trouble for electrical engineering students. This problem occurs due to occurrence of substandard voltage, may be substandard current, and of frequency which contain harmonics which may damage to power ...

Intelligent solid-state voltage restorer for voltage swell/sag and harmonics
IEE Proceedings - Electric Power Applications, 2004Voltage swell/sag along with extended undervoltage conditions and voltage harmonics are of vital concern to the majority of industries today. A neural network control method for the problems of voltage sag/swell and harmonics is proposed. A novel topology of the AC-AC boost converter solves the problems of voltage swell/sag, while a voltage controlled ...

Application of Dynamic Voltage Restorer in microgrid for voltage sag/swell mitigation
2015 IEEE Power, Communication and Information Technology Conference (PCITC), 2015Microgrids are becoming increasingly attractive to consumers as it allows utilization of freely available renewable energy sources. They are usually installed at consumer's sites i.e the distribution end. Due to high penetration of distributed generation units with different types of loads, microgrids can cause power quality and power control issues ...

Mitigation of Voltage Swell by Switched Autotransformer with Random Hysteresis Voltage Control
2011 Asia-Pacific Power and Energy Engineering Conference, 2011This paper presents a voltage swell compensator based on a switched autotransformer by random hysteresis voltage control. The advantage of this compensator is that it uses only one controlled switch per phase with no energy storages. Also the control scheme purposed here distributes the harmonic spectrum of the load voltage and reduces its total ...

Compensation of voltage sags and swells by using Dynamic Voltage Restorer (DVR)
2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016The most important aspect for electrical engineering is power quality in recent year. Power quality problem is an event of abnormal voltage, current or frequency. Utility distribution networks experience from various types of disturbances. The major problems dealt here are the voltage sags/swells.

Mitigation of voltage swells by static series compensator
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004Swells and overvoltages can cause overheating, tripping or even destruction of industrial equipment such as motor drives and control relays. This paper investigates the possibility of employing the static series compensator (SSC) to mitigate voltage swells/overvoltages.

Mitigation of voltage sag/swell with CSI-IDVR
2015 International Conference on Recent Developments in Control, Automation and Power Engineering (RDCAPE), 2015The distribution system contains various types of loads. These loads can be broadly classified as sensitive loads and non-sensitive loads. The sensitive loads are easily affected with power quality problems. Hence, power quality improvement is major concern in the distributed system.
