Individual Blade Pitch Control Using Feed Forward LIDAR
Catch the Wind's Senior Technical Director, Fred Belen, gave the following presentation at CanWEA 2011 in Vancouver, BC in a session titled "R&D - New Technologies." This presentation focused on feed forward yaw control results and future pitch control development opportunities.
Catching the Wind: An Update on Improved Yaw Alignment
This paper presents results based on 19 months of testing on utility scale wind turbines, which show the improvements in wind turbine control and average energy output that can be gained by measuring
Yaw Control: The Forgotten Controls Problem (Paper)
This paper presents yaw misalignment and power data collected from an operating utility-scale wind turbine.
Increased Power Production From Utility Scale Wind Turbines With Laser Wind Sensor Control
Catch the Wind Inc.’s poster presentation, Increased Power Production From Utility Scale Wind Turbines With Laser Wind Sensor Control, was given at the Canadian Wind Energy Association’s Conference and Exhibition, November 1-3, 2010 in Montreal, Canada.
This presentation focused on the advantages of using forward looking laser wind sensing technology to measure wind speed and direction in the undisturbed inflow in front of each wind turbine. Recent test results show that using more accurate and timely wind data to control a wind turbine improves its performance by increasing power output and reducing turbine stress.
Laser Wind Sensors Address Challenges to Development of Offshore Wind Energy
Catch the Wind Inc.’s poster presentation given at the North American Offshore Wind Conference and Exhibition, hosted by the American Wind Energy Association (AWEA) October 5-7, 2010 in Atlantic City, NJ.
The presentation, Laser Wind Sensors Address Challenges to Development of Offshore Wind Energy, used recent test results to compare measurements taken by a laser wind sensor with those taken by traditional anemometry and the disadvantages of using the latter to control a wind turbine.

SWANtech NPPD Data Report Results
SWANtech, a business unit of Curtiss-Wright Flow Control Company, published results of third-party analysis of Catch the Wind Inc.’s (CTW) field trial with Nebraska Public Power District (NPPD). This trial analyzed the benefit of using the forward wind sensing capability of CTW’s nacelle-mounted Vindicator® Laser Wind Sensor (LWS), which can optimally align a wind turbine with approaching wind. SWANtech’s results show reduced stress using the Vindicator® LWS’ forward-looking wind speed and direction measurements for turbine control.
