The Design of Simulator for Inter-Harmonic Detection with ESPRIT

Abstract

Inter-harmonics which exist in non-integer multiples of main harmonics cause power quality problems. In this study, in order to overcome power quality problems, ESPRIT algorithm which is one of the methods used for inter-harmonic detection which couldn't be accomplished by conventional spectrum analysis methods such as Fast Fourier Transform was realized in MATLAB environment. Software which was prepared in MATLAB environment has properties which are creating input signals, importing external signals, plotting frequency spectrum which is computed from obtained values with ESPRIT and presenting relative error rate of real signal values and ESPRIT algorithm values.

“…One of the key components of training and educating engineers, technicians, and operators in the use of PLCs is laboratory work. Laboratory work allows students to gain hands-on experience with PLCs in a controlled environment, but it also has its limitations, such as a lack of flexibility and the risk of equipment damage [1,2,10].…”
