Generación de ruido impulsivo para líneas de energía eléctrica “in door”

Abstract

Impulsive noise is one of the most harmful interference to communications by electric power lines inside buildings. Some mathematical models of this type of noise, based on the statistical behavior of noise, have been reported in the literature specialized in the subject. In this thesis work, several of these models are studied and one of them is deepened, implementing on that basis, an impulsive noise generator at a simulation scale. This generator has been implemented using the Matlab programming platform, which is described in the thesis. A detailed analysis of each of the elements that compose it is presented, both from the point of view of the mathematical model and its implementation. Finally some results obtained with it are shown, which include a comparison with impulsive noise measured in a hospital institution during the connection and disconnection of medical equipment. In the Introduction the design of the research, the scientific problem, the hypothesis, the objectives of the work, tasks and expected results are presented. In chapter 1, the scientific problem is clarified, for which a bibliographic analysis on PLC communications is carried out. Chapter 2 presents the models reported in the literature to generate impulse noise in PLC and details the one proposed by Chaouche in (Chaouche, Gauthier, Zeddam, Tlich, & Machmoum, 2011). In Chapter 3, the Matlab implementation of the Chaouche model is developed, and the results are presented. The Conclusions and Recommendations present the conclusions of the research carried out, and the unresolved aspects in which the author recommends further research.
