How to mitigate the negative effects of harmonics?

Harmonics issue

The increasing integration of VFDs (variable frequency drives) in industrial IoT and critical power systems is contributing to the rising problem of harmonics disturbances. Harmonics are produced by devices that have a non-linear load and a switch-mode power source. Personal computers, LED lights, and AC and DC motor drives were among the things covered.

VFDs are utilized in practically all electrical industrial motors to accurately regulate the motors in order to assist conserve energy and save money while also providing a greener operating approach. The issue is that employing VFDs can have an impact on electrical dependability since adding such a device to an electrical network distorts the perfect sign wave of the fundamental frequency.

There are two options for dealing with this problem. One option is to use SSDs with incorporated mitigating technologies. The alternative is to take a proactive approach to harmonic mitigation at the system level.

As a result, it’s a good idea to think about harmonic mitigation at the system level. The optimal solution, whether incorporated at the drive level or via a standalone power factor correction filter—such as Strong Power AHF—depends on a number of criteria, including the number of drives and their distribution, the quantity of power consumed, and the levels of compliance required.
