Fusion: Practice and Applications FPA 2692-4048 2770-0070 10.54216/FPA https://www.americaspg.com/journals/show/2850 2018 2018 Technical University of Cotopaxi, Cotopaxi, Ecuador Jessica Jessica Technical University of Cotopaxi, Cotopaxi, Ecuador Guido G.

Freire University of the Armed Forces, ESPE, Ecuador Javier Culqui The development of transportation today encompasses a broad range of technological applications that occasionally present new challenges arising from difficulties that require solutions. The article analyzes the difficulties in electric trains concerning the compensation of electric power quality in a traction system using a parallel active power filter (SAPF). From the literature review of several studies, the test distribution system in a distribution network for an electric train system is analyzed, with a variable load and harmonic content. The estimation and control technique used in the SAPF to compensate for the harmonic content and reduce the reactive power at the output of a traction substation is described. A data fusion management strategy is employed in the analyses, demonstrating the system's effectiveness. 2024 2024 08 21 10.54216/FPA.160201 https://www.americaspg.com/articleinfo/3/show/2850
