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 non-linear 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.
