Regulatory Compliance<\/p>\n<\/div>
Tower installation and instrumentation placement were performed in accordance with <\/span>IEC 61400-12-1 Ed.2<\/b> and <\/span>MEASNET recommendations<\/b>. The assembled anemometers were calibrated and installed following these regulations<\/span><\/p>\n<\/div>Certifications<\/p>\n<\/div>
DNV (Det Norske Veritas)<\/b> reviewed the installation report, comparing its contents with the photos provided and the parameters programmed into the data logger.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>Description of the work undertaken<\/p>\n<\/div><\/div><\/div>
Telener 360<\/b> was contracted for the installation of a<\/span> meteorological tower (wind mast)<\/b> for the <\/span>La Salle Wind Farm<\/b>, located in <\/span>Illinois (United States)<\/b>; about 147 km from the city of Chicago. The HICKORY mast, of type <\/span>TZ-90<\/b> and with a total height of<\/span> 160 meters<\/b>, was installed on <\/span>May 14, 2021<\/b>. The structure of the tower was specifically designed to withstand wind loads, and its fabrication consists of 3-meter-long triangular sections with a hot-dip galvanized coating.<\/span><\/p>\n <\/p>\n
The project focused on the installation of an <\/span>extensive range of meteorological instrumentation <\/b> in accordance with IEC 61400-12-1 Ed.2 and MEASNET recommendations. This included the installation of <\/span>eight Thies <\/b>anemometers<\/b> at various heights (60m to 160m, with redundancy at 160m and 120m) and one <\/span>vertical anemometer <\/b> at 156m. Four First Class wind vanes between 56m and 155.3m were also mounted, whose orientation and displacement were meticulously calculated <\/span>in situ<\/span><\/i> by compass measurements. The mast also has <\/span>two temperature and relative humidity sensors <\/b>(at 155m and 10m), an atmospheric pressure sensor (at 155m), obstacle lights (at 155m and 85m) and a lightning rod.<\/span><\/p>\nA<\/span> particular feature<\/b> of this project was the <\/span>inclusion of an SM3BAT bat detector<\/b>, with the microphone at 40m and its recorder at 2m, programmed for nighttime monitoring of bat passes and pulses. <\/span>All data is recorded by an<\/b> Ammonit Meteo-40M data logger located at a height of 2 meters, with <\/span>remote access<\/b>. <\/span>The system is self-sufficient in energy through three<\/b> 410W<\/span> photovoltaic panels and 12 12V batteries<\/b> with a capacity of 20Ah.<\/span><\/p>\n<\/div><\/div><\/div>
