Desarrollo de una herramienta computacional mediante lenguaje de programación Python, para establecer los ajustes de la protección diferencial en líneas de transmisión.

Abstract

Currently, protection engineers determine the parameters of the extreme line differential protection in the setting recommendations presented in the manuals of each manufacturer, recommendations that don't cover all the conditions in which the LT operate. For this reason, it's necessary to understand the reasoning behind each setting to use each system correctly and more closely to the reality. Therefore, the objective of this degree work is to make a computational tool in the Python programming language that, through the interaction and automation of the Python script with PowerFactory - DIgSILENT, allows the simulation of short-circuit in the TL of study to determine the operating and restraint currents, which helps to establish the line differential protection settings. The computational tool is applied to the 138 kV Cuenca – Yanacocha TL where the results are validated by comparing the effectiveness of the calculated settings.
