New factor for voltage sags characterization
A new factor which allows characterizing voltage sags in an individual way is presented in this paper. The factor acts revises and identifies voltage sags in a univocal way.

Dual 3-Phase Bridge Multilevel Inverters for AC Drives with Voltage Sag Ride-through Capability
One of the main power quality issues that can affect variable speed drives (VSDs) is the occurrence of voltage sags on their AC power supply. Voltage sags can affect the inverter nominal operation, leading to a malfunction of the AC motor.

Mitigation of Voltage Sags in CIGRE Low Voltage Distribution Network [PDF]
Any problem in voltage in a power network is undesirable as it aggravates the quality of the power. Power electronic devices such as Voltage Source Converter (VSC) based Static Synchronous Compensator (STATCOM), Dynamic Voltage Restorer (DVR) etc.

Propagation of Voltage Sags and Under-voltages through Scott Transformers
Scott transformers are a class of equipment thatconverts three-phase power into two-phase, four-phase and eventhree-phase power and vice versa. This paper investigates howvoltage sags originating from the main three-phase networkpropagate through these ...

Fast Transient Hybrid Neuro Fuzzy Controller for STATCOM During Unbalanced Voltage Sags [PDF]
A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid.

A Voltage Sag Pattern Classification Technique [PDF]
This paper presents an investigation on pattern classification techniques applied to voltage sag monitoring data. Similar pattern groups or sets of classes, resulting from a voltage sag classification, represent disturbance categories that may be used as indexes for a cause/effect disturbance analysis.
