Item Intelligent, sustainable and integrated system of management of structures(International Association for Bridge and Structural Engineering (IABSE), 2019) Royes, Miquel Morata; Gil, Lívia Garcia; Caldentey, Alejandro Pérez; Vila, Javier Gimenez; Lasso, Abel Capelastegui; Navascues, Óscar Muñoz; Infraestructuras y Edificios; SMART_MONIn Spain, the national road network comprises over 17.000 bridges and viaducts, besides those managed by local and regional administrations. Many of these structures are very old; however, it was not until the 90s of the XX century that maintenance awareness rose among the society. Inspections are currently carried out visually, on a manual basis, implying low effectiveness and high costs. To tackle these issues the SISGES project was conceived and aimed at developing a smart management system capable of making rational decisions regarding the maintenance and repair of existing structures. The methodology that has been followed to achieve this goal is to study the current available technologies, develop a data management structure, develop a monitoring system for each structure, create a structural model while considering interoperability with BIM and finally, develop a management application/software to be used for both technical profile users and general managers. The SISGES platform comprises remote inspection technology, which reduces the inspection times and costs while increasing workers’ safety; continuous monitoring technologies, registering displacements, vibrations, temperature and humidity; scanning technologies to create three-dimensional models of the structures and BIM technologies to assign each element with an attribute. Overall, this makes an innovative and integrated infrastructure management system in line with available technologies and capabilities while maximizing the efficiency of inspection and monitoring for current and future bridges and viaducts.Item Wind turbine monitoring for control versions comparison(NDT.net, 2016) Campion, Juan Carlos Perez; Ros, Maria Isabel; Sanchez, Javier; Ortega, Juan Antonio; Sanchez, Juan Carlos; Quero, Fernando; FACTORY; SG; MercadoThe wind is one of the most important sources of energy nowadays. Wind turbine generators (WTGs) have undergone enormous change, with new components and new control strategies being designed to improve their performance. WTG control is the most important component although at the same time it is also the least-known system; it is considered a black box. WTG control strategies are aimed at generating as much power as possible, while keeping the loads in each component below certain limits. If these strategies perform poorly, component life span could be reduced, decreased power production and even WTG collapse. These control strategies are developed by the WTG suppliers who release them as new control versions when a new strategy is implemented or when a failure has been detected in a previous version. In order to understand more about these little-known strategies Iberdrola Renewables has designed a monitoring system for control version comparison. The monitoring system has been designed to collect more information from the WTG, and new sensors have been placed in the blades, drive train and tower in order to compare different control versions. With this new design, Iberdrola Renewables is able to detect any positive or negative impacts on our fleet of these new control versions launched by the suppliers.
