Researchers at Sandia National Laboratories recently completed a new software package to control the data acquisition of two meteorological towers at the Scaled Wind Farm Technology (SWiFT) facility. With this deployment, the real-time operating system can now display live weather conditions for the operator.
Future SWiFT experiments will rely on this weather data to precisely control the turbine, avoiding the issues typically associated with nacelle measurements which are corrupted by the presence of the turbine. The software package converts voltage readings from the analog sensors (wind vane, cup anemometers, humidity, and barometric pressure) to engineering units. These values are then tabulated into the same log file as the digital sensors (sonic anemometers) in 10-minute increments.
