Characterizing voltage sags and swells using three-phase voltage ellipse parameters

2014 IEEE Industry Application Society Annual Meeting, 2014
This 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..

Dynamic Control Strategy in Medium Voltage DVR for Mitigating Voltage Sags/Swells

2006 International Conference on Power System Technology, 2006
This paper presents control algorithm for dynamic voltage restorer (DVR) to improve voltage quality problems such as voltage sags/swells in distribution systems. When voltage sags/swells occur, possibly, due to faults and some load switching, DVR has to detect the problem and inject appropriate voltage component as soon as possible.

Mitigation of voltage swells by static series compensator

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
Swells 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 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 ...

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 ...
