Laser-based wind sensor lets turbines grab more power
August 8, 2010 by KRemington
Filed under Turbine Sensors
Excerpt: For decades, large utility scale wind turbines have been forced to rely on mechanical wind sensing devices that are mounted on the nacelles of the turbines to measure the wind speed and direction. These signals are fed into the wind turbine control system to adjust the turbine nacelle to …
Motion sensors for wind turbines
July 6, 2010 by KRemington
Filed under Electrical Systems, Turbine Sensors, Wind Power News, Wind Turbine Design
Excerpt: Optipact motion sensors measure velocity by calculating the rate at which markers on a moving surface travel across an optical sensor. With no contact between sensor and the moving surface, dust or surface contaminates will not cause problems. The sensors provide an ideal way to determine …
Heated anemometer works in freezing weather
May 26, 2010 by Paul Dvorak
Filed under Turbine Sensors, Wind Power News
Excerpt: Cup anemometers can generate inaccurate wind-speed values in gusty periods, and should one freeze, its turbine may have to shut down. One solution is an ultrasonic anemometer, like the Ventus UMB 8371 with a 240W heater. This unit provides precise and maintenance-free measurements of wind velocity a …
