A review and study of harmonic mitigation techniques

A periodic wave having a frequency that is an integral multiple of the fundamental power line frequency component is harmonics. They are the byproducts of modern electronics devices so it is necessary to mitigate the harmonics and offer techniques to mitigation of harmonics. This paper provides an explanation of the various harmonic mitigation techniques available to solve harmonic problems in three phase power systems. Included are the advantages and disadvantages of each method, their normal circuit connection as well as typical performance that can be expected when each method is properly employed.
