Power system harmonics cause many problems like equipment failures, malfunctions and plant shutdowns. Accordingly, mitigation of these harmonics is considered an important target especially for the industrial applications where any short downtime period may lead to great economic losses. There are at least ten different mitigation techniques to choose from, each with specific technical advantages and disadvantages. Comparative studies for the harmonic mitigation techniques in industrial electrical systems are rarely found in the literature even though they are strongly needed. This paper, almost for the first time, provides comprehensive technical comparisons between the various practical harmonics mitigation techniques in the industrial electrical systems. This has been carried out with the aid of our research and experience in the industrial field. Hence, this paper is considered as a helpful guide for design engineers, consultants and customers of the industrial sector.
