Small Wind Turbine

At the Sotavento Wind Farm there is, so far, only one small wind turbine installed. Like the rest of the facilities there is monitored and stored information regarding the main parameters.
The power rating of the turbine is 1.5 kW. The installation, as with the solar photovoltaic, is included within the aim of covering the electricity needs in the bioclimatic house.
It is located at the north east end of the house on a self-supporting tower at the height of 8 metres. The wind turbine is the two-bladed type, with an upwind passive orientation.

Small Wind Turbine (1)

Technical Description


The model of the wind turbine is the BORNAY 1500 INCLIN, with blades made of fibre glass and carbon fibre. The generator is of the synchronous type, tri-phasic with neodymium permanent magnets, these being responsible for transforming the mechanical energy supplied by the electric power blades. The generated alternating current is of variable frequency and voltage. Therefore, in the plant room, it is rectified through an inverter to DC, then returning to be transformed into appropriate alternating current of the power and frequency suitable for injection into the network.
Both electrical and weather variables are monitored and stored, in order to evaluate the behaviour of this mini-turbine:

Access and download data


The system parameters of the small wind turbine at Sotavento Wind Farm are stored in a database and integrated into an application data download. This application allows organizations, companies or universities that have Sotavento partnership agreements access to data needed for the development of projects.
