Voltage sag is defined as a short reduction in
voltage magnitude for a duration of time. It is
considered to be the most common power quality
issue.
This book presents various voltage sag indices
proposed by electrical association organisations as
well as ones suggested by researchers. Furthermore,
mathematical descriptions of proposed voltage sag
indices are
derived. The indices are verified against various
types of load, loading levels, and line X/R ratios.
Mathematical analysis and verification against the
IEEE four and thirteen node test feeders concludes
in various versatile real time voltage sag indices
known as the combined voltage index and voltage
sag proximity index .
In order to illustrate the real time applicability
of the voltage sag indices they are used in
conjunction with a mitigation technique, where they
are proven to be efficient and discriminative.
Furthermore, a methodology is mathematically
developed and proposed for Interconnected System
Voltage Sag Prediction. The proposed methodology is
verified through successful application of the steps
on IEEE four bus interconnected system.
