    Identificación de anomalías en el aislamiento de líneas de transmisión a partir de imágenes
    (Universidad EAFIT, 2024) Sánchez Echeverri, Daniel Alonso; Martínez Vargas, Juan David; Valencia Díaz, Edison
    Currently, the maintenance of electric power transmission lines is based on inspection tasks that require long journeys over complex terrain to determine the condition of this infrastructure. Technological advances in unmanned aerial vehicles, also known as drones, have allowed some inspection tasks to be performed remotely, capturing photographs of the infrastructure. These images are then analyzed to identify the physical condition of the assets. However, processing and visualization is a manual procedure that requires hours of review to identify problems. In this context, the present work proposes the use of artificial vision algorithms, in order to identify the elements of the network that present anomalies, affecting the normal operation of the electric power transmission system. With this strategy, it is expected to improve the efficiency in the identification of problems in the electric power infrastructure, reducing the time and costs associated with the manual review of the images obtained by the drones. The dataset has been obtained from a company in the electric power sector in Colombia. In this paper, for reasons of data protection and business ethics, the company has been anonymized and renamed as Empresa de Energía EE.

    Uso de energías alternativas en taladros de perforación de pozos de petróleo y gas en Colombia

    The oil industry faces the challenge of advancing toward more efficient and sustainable operations within the context of the global energy transition. Drilling rigs - both onshore and offshore - have high energy demands. Traditionally, these demands have been met by diesel-powered systems, which entail high operating costs and significant carbon dioxide (CO2) emissions. For this reason, the integration of renewable energy sources - such as photovoltaic solar systems, wind power, green hydrogen, battery energy storage systems (BESS), and hybrid microgrids - represents a strategic opportunity to reduce diesel consumption, optimize costs, and decrease the environmental footprint without compromising operational reliability. International evidence (Arent et al., enero de 2019; Saber et al., 2019) shows that, in the short and medium term, the most feasible configuration is the renewable-diesel hybrid scheme, which supplies the base load with clean energy and uses diesel generators as backup for peak demand and contingencies. This approach requires analyzing hour-by-hour load profiles, fuel consumption, and the operational conditions of each site. In Colombia, the availability of solar and wind resources, along with incentive policies (Law 1715 of 2014, which regulates the integration of non-conventional renewable energies into the National Energy System) and the interest of key actors such as Ecopetrol and Celsia, create a favorable environment for pilot electrification projects in drilling operations. However, challenges persist: high capital expenditures (CAPEX), payback periods, regulatory complexities, and logistical and environmental considerations, especially in regions such as La Guajira.
