The engineering economics of power systems harmonics in subdistribution feeders: a preliminary study

摘要

A method for the computation of the cost of harmonic losses in a subdistribution feeder is presented. The cost of harmonics, including the cost of the filters, is compared with the cost of the 60 Hz power loss as well as the total annual cost of the system. Evaluating the cost of harmonic current $/A/year or the incremental cost of the harmonic reactive power, $/kVar/year, is recommended.
