Mathematical Analysis and Simulation in Matlab of Differential Protection in Power Transformer with Two Windings

Abstract

This project deals with the realization of Mathematical Modeling and simulation in MATLAB of Differential Protection in Two-Winding Power Transformers, the same one that will be part of the Salesian Polytechnic University, Guayaquil headquarters; will have the objective of simulating the operating conditions of the protection equipment (SEL 587) found in a Substation, obtaining the equation that governs the differential protection operations of said relay, by theoretically analyzing the system conditions, both under normal conditions and for any fault event (external fault, internal fault) on the primary and / or secondary side of the transformer, facilitating students who are in the last cycles of the Electrical Engineering career, learning the concepts and principles of operation of System protections Electric Power.
