Small-scale wind power
At the Sotavento Wind Farm, a single small-power wind turbine has been installed to date. As with the rest of the facilities, information regarding the main parameters is monitored and stored.
The nominal power of the wind turbine is 1.5 kW. The installation, like the solar photovoltaic system, is designed to meet the electricity needs of the bioclimatic house.
It is located to the northeast of the house on an 8 m high self-supporting tower. The wind turbine is a two-bladed type with passive upwind orientation.
Technical description
The wind turbine model is the BORNAY INCLIN 1,500, with blades manufactured from fiberglass and carbon fiber. The generator is a three-phase synchronous type with permanent neodymium magnets, which is responsible for transforming the mechanical energy provided by the blades into electrical energy. The generated alternating current has variable frequency and voltage; therefore, in the plant room, it is rectified through an inverter to direct current, before being transformed back into alternating current under suitable voltage and frequency conditions for grid injection.
Both electrical and meteorological variables are monitored and stored in order to evaluate the performance of this small wind turbine:
Monitored parameters
- Wind speed
- Wind direction
- Voltage, current, active and reactive power on the AC side
- Instantaneous power
- Accumulated energy generated

DATA ACCESS AND DOWNLOAD
The parameters of the small-scale wind power installation at the Sotavento Wind Farm are stored in a database and integrated into a data download application. This application allows organizations, companies, or universities with which Sotavento maintains collaboration agreements to access the information necessary for project development.
