    Modelo y análisis de armónicos en sistemas de distribución
    (2018) Genovez Ramírez, Karla Gabriela; Ureña Torres, Bryan Freddy; Torres Contreras, Santiago Patricio; Molina Cobos, Manolo Alejandro; Quituisaca Astudillo, Silvio Patricio
    This work proposes a modelling methodology for studying the harmonics levels in electric distribution systems and analyzing the distortion generated due to the growing use of nonlinear devices in the network. Initially, a review of state of art is presented, where the most relevant models in literature are detailed. Also, the methodology used to represent the aggregate time-varying loads, by applying a load distribution process and characterization method of harmonic current source for each kind of customers, is described. Using Power Factory DIgSILENT software, the network model is created throughout the DGS file exchange interface based on the GIS information. This software is also used to analyze the network running harmonic power flows. In addition, a script was developed using DIgSILENT Programming Language DPL for automating the simulation procedure to obtain results in a one day period. The methodology was implemented in 0324 feeder, including several case studies that incorporate induction cookers, photovoltaic panels, electric vehicle chargers and external voltage distortions within the feeder. Finally, measurement and simulation results of the base case are compared, verifying the accuracy of model; the results of each scenario are analyzed.
