Abstract

The focus of this paper is to recognize and to calculate the harmonics and develop a simulation method to investigate this concept in an interconnected power system containing nonlinear loads with resistive, inductive, and capacitive impedances. The IEEE 519 recommended practice provides indices to determine distortion as well as recommending limits within which systems containing harmonics should operate. Difficulty in solving harmonics problems is, as a renowned truth, initiated with the complexity to illuminate source and consequence between harmonic source and utility power systems. If we could measure harmonic current of inflow to load side from convenience power network and outflow to efficacy power network from load side, the harmonic problem will be effortlessly resolved and prohibited. Several varieties of harmonic instruments are being used, still, no realistic technology has been presented so far. We have developed the entire harmonic power (THP) methodology is one amongst the strategies planned within the literature for this purpose. This paper tries to indicate that the source of harmonic pollution is downstream with respect to the nodes (i.e., the load is the source of harmonic pollution). Then, a modification to the strategy is planned to generalize its application to non-radial systems.
