Metodología para la evaluación de tensiones inducidas en tuberías, ocasionadas por la interacción con líneas aéreas de transmisión de alta y extra alta tensión (HVAC, HVDC y corredores híbridos)

Abstract

El presente trabajo, tiene como alcance desarrollar una metodología integral para el tratamiento de inducciones generadas y ocasionadas por líneas de transmisión aéreas de alta tensión (HVAC y HVDC), en infraestructura (principalmente en tuberías oil and gas, aunque el fundamento y análisis puede ser extendido para ser usado en otro tipo de infraestructura); este tipo de cruces es el más común y se presenta a menudo en la evaluación de coexistencia entre proyectos.

The rapid growth of the population in the last two decades has led to an increase in the demand for electrical energy (5.51% growth in 2021 compared to 2020 in Colombia) and consequently to a great expansion of the transmission electricity network of Colombia (currently Colombia has a power transmission network (STN) of 28455 km); however, due to the lack of availability of land, complexity in the closing of agreements for the acquisition of these, negotiation of right of way and added to the environmental cost; In many cases, right of way of the transmission lines have been shared with gas infraestructure, oil infraestructure and even water pipelines. In other words, under the same right of way, the projects can coexist or are sometimes very close due to the availability of the land. The foregoing gives rise to the problem of electromagnetic induction on the affected infrastructure (piping and other elements), due to the couplings that arise between the two systems, which can be divided into three categories: capacitive, inductive and conductive that will be reviewed. and analyzed in detail in this work. In the same way, security and integrity factors and mitigation measures are reviewed in order to mitigate the adverse effect caused by induction. The research has as starting point a series of clear objectives, based on an analysis of the state-of-the-art product of a wide and extensive bibliographic review, which lead to developments with easily accessible software to corroborate some models; with this, finally can be issued the recommendations that allows the reader to approach and analyze the problem in an integral way.
