Abstract

Currently mathematical morphology is used in the analysis of electric signals due to the clear understanding of its processes and results. Traditional filters use elements based on electronic power to eliminate harmonics. The aim of this paper is to describe the use of this method for filtering harmonic signals using four basic operations of mathematical morphology such as: dilatation, erosion, opening and closing, including necessary simulations and analysis to confirm its correct functioning. The presented work is applied to real signals measured in the laboratory of electric machines at Universidad Politécnica Salesiana Cuenca. Results show the effectiveness of the algorithm in removing harmonics from the input signal in order to get a signal as similar as possible to the fundamental component.
