- Aerial sonic anemometry for wind resource assessmentPublication . Ribeiro, Luís Frölén; Marques, FilipeThis project intends to recur to sonic anemometers in a airborne platforms to get wind information over the flying area between met masts or waypoints. Multiple platforms measuring simultaneously to complement ground based measurements. The concept is being tested and preliminary results show that key issues are related to the positioning system – differential GPS and autopilot.
- Governance windscanner.PT national research infrastructure (PINFRA/22207/2016)Publication . Grosso, José; Campos, José; Ribeiro, Luís Frölén; Simões, TeresaThis document presents the governance structure foreseen for the operationalization of the WindScanner.PT research infrastructure. The methodology for the implementation of the governance structure, followed the one developed for the European Infrastructure WindScanner.EU, which was the origin of this Portuguese RI. However, as the European RI did not move forward due to a series of situations related to the infrastructure financing rules of the various members of the European consortium. In this sense the Portuguese consortium decided to maintain the project and adapt the RI structure to the Portuguese context and follow a simple model based on the usual research projects, and based on the governance structure defined for WindScanner.EU.
- WindS@UP: the e-science platform for windscanner.euPublication . Gomes, Filipe; Lopes, João; Palma, José; Ribeiro, Luís FrölénThe WindScanner e-Science platform architecture and the underlying premises are discussed. It is a collaborative platform that will provide a repository for experimental data and metadata. Additional data processing capabilities will be incorporated thus enabling in-situ data processing. Every resource in the platform is identified by a Uniform Resource Identifier (URI), enabling an unequivocally identification of the field(s) campaign(s) data sets and metadata associated with the data set or experience. This feature will allow the validation of field experiment results and conclusions as all managed resources will be linked. A centralised node (Hub) will aggregate the contributions of 6 to 8 local nodes from EC countries and will manage the access of 3 types of users: data-curator, data provider and researcher. This architecture was designed to ensure consistent and efficient research data access and preservation, and exploitation of new research opportunities provided by having this “Collaborative Data Infrastructure”. The prototype platform—WindS@UP—enables the usage of the platform by humans via a Web interface or by machines using an internal API (Application Programming Interface). Future work will improve the vocabulary (“application profile”) used to describe the resources managed by the platform.
- Business plan windScanner.pt research infrastructure - national research infrastructure (PINFRA/22207/2016)Publication . Grosso, José; Campos, José; Ribeiro, Luís Frölén; Simões, TeresaWind energy is becoming one of the leading sources of power in Europe. The installed capacity increases each year, with the offshore wind gradually evolving with even more significant potential than onshore [1]. This growing tendency has also been promoting a more extensive research effort in this area, pushed by the climatic crisis that has also driven political support from multiple nations across Europe. Wind energy has employed over 250 thousand EU citizens and contributed to around 10% of European electrical consumption. Although high milestones have been achieved, there is still much room to grow in the wind energy sector, particularly cost reduction.The WindScanner.pt project aims to create a European distributed research infrastructure based on high precision sensors able to analyze fluid dynamics in tridimensional volumes, offering the ability to understand atmospheric conditions and turbulence better. This asset will not only allow better assessment of the wind conditions. Still, it will also enable the evaluation of projects in other areas where fluid dynamics are relevant, such as civil engineering and the building industry, by scanning the surroundings of large structures such as bridges and viaducts and measuring structure oscillations [3].
- Perdigão 2015: methodology for atmospheric multi-doppler lidar experimentsPublication . Vasiljević, Nikola; Palma, José M.L.M.; Angelou, Nikolas; Matos, José Carlos; Menke, Robert; Lea, Guillaume; Mann, Jakob; Courtney, Michael; Ribeiro, Luís Frölén; Gomes, Vitor M.M.G. CostaThe long-range and short-rangeWindScanner systems (LRWS and SRWS), multi-Doppler lidar instruments, when combined together can map the turbulent flow around a wind turbine and at the same time measure mean flow conditions over an entire region such as a wind farm. As theWind- Scanner technology is novel, performing field campaigns with the WindScanner systems requires a methodology that will maximize the benefits of conducting WindScannerbased experiments. Such a methodology, made up of 10 steps, is presented and discussed through its application in a pilot experiment that took place in a complex and forested site in Portugal, where for the first time the twoWindScanner systems operated simultaneously. Overall, this resulted in a detailed site selection criteria, a well-thought-out experiment layout, novel flow mapping methods and high-quality flow observations, all of which are presented in this paper.
