Power System Harmonics Estimation Techniques: A Review

Abstract

Power Semiconductor Devices have been more
important in power systems during the last
several decades. Flexibility in AC transmission is
a new trend in the power system industry.
Transmission and distribution quality are
harmed by the use of Fact devices and nonlinear
loads in the distribution sector, resulting
in harmonic production. These harmonics may
have a devastating effect on the system if
necessary precautions are not followed.
Measurement of power harmonics components
is critical to the design of a filter that reduces
harmonics.
This study outlines a step-by-step process for
measuring the harmonic content of power
system signals, beginning with a traditional
technique and progressing to a soft computing
approach. Real-time analytic methods are the
focus of this course. The researchers in this field
may benefit from this review study.
