WINDUR: Installation, measurement and assessment campaign of wind resource in urban environment

The WINDUR project, in which Solute is participating, is active and in due course. One of the activities developed up to now is the installation of meteorological masts to launch the wind measurement campaign in urban environment.

This campaign is under development in the Iberian Peninsula and Spain is the country where most of the meteorological masts have been installed.

When designing the wind measurement campaign, engineers took into account several factors. Chief one: the available wind resource at low heights. The main source used to identify areas of potential interest was the national wind resource map of CENER (National Center of Renewable Energies). It supplied tentative information of the wind resource throughout Spain at 10 meters height and it was very helpful for experts to establish final locations for the met masts. At the same time, several meteorological stations and meteorological masts were consulted to have a better estimation of the existing wind at low heights and contrast the measurements offered by the national wind map of CENER.

Other conditions, which have had a great influence in the site election process, have been:

  • Fair representation of various climatological conditions, pursuing to obtain at least one register in each of the climate types Spain offers that are exportable to the rest of Europe such as: oceanic climate, continental climate and Mediterranean climate
  • Achieving permissions to perform the installations. Project members have been seeking for support from third parties, performing installations both in private (neighborhood communities, private industrial buildings, business with high electrical consumption) and public buildings (City halls and, in general, public buildings belonging to the public administration)
  • Compilation of areas belonging to various typologies and buildings to install the masts. Like the isolated and flat areas with some buildings grouped, the industrial parks in the surroundings of the cities are the best example, urban or periurban areas located between hills. Bearing in mind that elevated zones in the urban environment are the preferred ones to measure the available wind resource, those urban areas with obstacles, buildings and plane roofs

Eight meteorological masts have been installed in the next locations: La Coruña, Cadiz, Valladolid, Huesca(two masts), Guadalajara and Rivas-Vaciamadrid in Spain, and Porto, in Portugal. The aim of installing two meteorological masts in Huesca is to have two measurement points close to each other and analyze the evolution and characteristics of the wind influenced by the most common obstacles of the urban environment and, thus enabling the study the turbulent effects that apply in these kind of sites.

The instrumentation of the masts comprises anemometers, vanes, dataloggers… Additional features will be implemented in advanced phases of the project, like sonic anemometers. These will be installed to measure the turbulence originated by the urban obstacles. These masts are 3.5 meters high and all of them are installed on building rooftops, whose heights go approximately from 4 meters up to 20 meters above the level of the ground.

The goal of the project is to perform the wind resource assessment in eight relevant positions across the Iberian Peninsula and evaluate the data registered to develop a wind resource assessment software tool for urban and periurban areas. This will eventually contribute to the development of the vertical axis wind turbine prototype planned in the program.

In this way, Solute, in collaboration with the Uppsala University of Sweden, continues with its efforts to consolidate its position as a campaign design, installation and management expert company, with valuable wind resource assessment capacities, not only in the open field, but also in urban environments, where the obstacles are bigger as well as the wind turbulence.

Moreover, it empowers its capabilities in the development of Computational Fluyd Dinamics software required to quantify the wind resource in the urban environments. This module will be linked to the own software of wind resource assessment and wind prediction that Solute is developing internally in the project ETSWIND (http://www.solute.es/en/blog/2013/04/02/wind-prediction-and-wind-resource-assessment-etswind-project ). The resultant product will be one of the most complete and competitive software in the market regarding the analysis, assessment and wind prediction.
