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), 2018
This 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 ...

Mitigation of voltage dips and voltage swells by STATCOM/BESS

2006 China International Conference on Electricity Distribution (CICED 2006), 2006
A static synchronous compensator (STATCOM) with battery energy storage system (BESS) can be used to mitigate voltage dip/swell by injecting/absorbing active and reactive power to the point of connection with the grid. For this application, the dynamic performances of STATCOM/BESS are important since the load will not maintain normal operation if it is ...

Series Voltage Regulator for a Distribution Transformer to Compensate Voltage Sag/Swell

IEEE Transactions on Industrial Electronics, 2017
This paper presents a series voltage regulator for a distribution transformer which addresses power quality issues in the electrical power distribution system. The proposed system is comprised of a line frequency transformer connected to a power electronic converter which is autoconnected on the secondary side. This autoconnection is facilitated by use

About voltage sags and swells analysis

10th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.02EX630), 2004
Time 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), 2018
Quality 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 ...

Characteristics of Voltage Swell in Multigrounded Systems

IEEE Transactions on Power Delivery, 2007
The effects of multigrounded neutral (MGN) in three-phase distribution systems are not easy to analyze due to the presence of a fourth conductor-the neutral and its multigrounded arrangement. As a result, the mechanism of voltage swell in MGN feeders becomes difficult to understand.

Voltage sag/swell compensation in an interline Dynamic Voltage Restorer

2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011
The 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.
