Voeg label toe | Samenvatting: | This project is carried out in the laboratory of Basic Electronics in the Faculty of Engineering Sciences of Quevedo State Technical University, the general objective is to analyze the behavior of the single-phase power transformer, working individually or forming banks of transformers with different types of connections, before the presence of harmonics generated by nonlinear loads: the research methods used is the analytical, deductive - inductive method; the Quasi experimental technique and sources of information collection; as a result it was obtained that the increase of the temperature in the warmer point of the winding, above the ambient temperature, exceeds the allowable limit with nominal load. The study has made it possible to have an extensive bibliography updated on the subject of harmonics in general and their influence on transformers of power distribution in particular, which was achieved through an extensive bibliographical search, study and critical review Of the same; Numerous data have been obtained from the simulations that illustrate the work of electric power distribution systems and distribution transformers in particular. The MatLab programming language and its Simulink simulator were used, in which the Power System Blockset's specialized package of functions was used in an intensive way for the programming, simulation and analysis of the different cases treated in the work done; Different types of nonlinear loads were simulated analyzing the harmonic behavior of the same and their influence on the distribution transformer; the results were a set of problems by way of examples, which illustrate the analysis of an electric circuit in the presence of harmonics, among which we can note: the calculation of the factor K of a nonlinear load and the derating of the distribution transformers. |
