Mitigation of Voltage Sag And Voltage Swell By Dynamic Voltage Restorer
2019 International Conference on Intelligent Computing and Control Systems (ICCS), 2019This work deals with reducing major voltage flickering problems by using dynamic voltage restoration and SPWM technique it helps to improve the power quality of the system. Even though voltage swag and swell occurs in transmission as well as distribution side but the problem is resolved only at the distribution side.

Extended Voltage Swell Ride-Through Capability for PWM Voltage-Source Rectifiers
IEEE Transactions on Industrial Electronics, 2002Voltage swells are one of the most harmful voltage disturbances for static power converters. A supply voltage increase may severely damage or trip converters, causing production and revenue losses. In the case of the PWM voltage source rectifier, a swell causes saturation of its control system, followed by a transition to 6-pulse operation that leaves ...

Characterizing voltage sags and swells using three-phase voltage ellipse parameters
2014 IEEE Industry Application Society Annual Meeting, 2014This paper presents an algorithm for detection, classification and characterization of voltage sags and swells in electricity networks, using three-phase voltage ellipse parameters. The proposed method employs the instantaneous magnitude of three-phase voltage signals in three axes, which are separated from each other by 120°.

About voltage sags and swells analysis
10th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.02EX630), 2004Time at level analysis of discrete events is proposed to characterize voltage sags and swells instead of the simple magnitude vs duration characteristics presently used. Although requiring a little more computer memory and digital processing, the proposed methodology constitutes a significant improvement for the characterization of unpredictable ...

Detecting Voltage Swell, Interruption and Sag
2018 19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2018Quality control of electrical energy and timely detection of interference and distortion of supply voltage is a very important task. This is necessary both to find the source of distortion, and to compensate for distortion. In this review, we consider the problem of detecting random events: voltage swell, interruption, and voltage sag in the power ...

Voltage sag/swell compensation in an interline Dynamic Voltage Restorer
2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011The Dynamic Voltage Restorer (DVR) provides an advanced and economical solution for both voltage sag and swell problems. The voltage-restoration process involves real-power injection into the distribution system. The Interline DVR (IDVR) proposed in this paper provides a way to compensate the voltage deviation caused in a feeder.

Voltage Dips and Swells in Low Voltage Networks of Estonia
2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2018This paper is focused on power quality, particularly on voltage dips (sags) and swells in low voltage (LV) networks of Estonia. Measurements were carried out along with analysis of dips and swells and the results are presented in this paper. The origin of voltage dips and swells is discussed, also magnitude, duration and density of dips is analysed ...
