Abstract

Harmonic source detection becomes important in an interconnected power system in a deregulated power situation. In electrical systems, harmonics cause current and voltage to be warped and vary from sinusoidal waveforms. Nonlinear loads connected to the distribution system create harmonic currents, which are the result of nonlinear loads converting AC line voltage to DC. Nonlinear electronic switching devices, such as variable frequency drives (VFDs), computer power supplies, and energy-efficient lighting, introduce harmonics into the electrical system. One of the most significant effects of power system harmonics is an increase in system current. This is especially true for the third harmonic, which generates a significant rise in the zero sequence current and, as a result, an increase in the neutral conductor current. This paper gives a thorough examination of the system developed using Matlab R2020a Simulink and Matlab R2020a GUI and the Impedance Spectrum approach, as well as their main advantages and disadvantages. With accuracy as the primary criterion, it is stated that harmonic source determination and harmonic estimation are better suited to Impedance Spectrum methods using harmonic state estimation. Correct harmonic source identification methods are crucial in a deregulating environment when there is insufficient information on the topology of the power system, therefore research in this area is very important.
