Virginia, United States [RenewableEnergyWorld.com] Catch the Wind Ltd. announced that its Vindicator laser wind sensor (LWS) successfully improved the alignment of a turbine against oncoming wind during a field trial with Nebraska Public Power District.
The trial program was specifically designed to evaluate how using forward measurement of wind speed and direction can optimally align wind turbines with the approaching wind and reduce the off-axis stress loads on turbines.
During the field trial, Catch the Wind’s Vindicator LWS improved the yaw alignment control of a turbine significantly over traditional wind vane measurement equipment. Improving yaw control alignment is a key requirement of the wind energy industry as it results in reduced stress loads and improved energy production output.
“We are very pleased with the preliminary results of our field trial with Nebraska Power,” said Phil Rogers, president and CEO of Catch the Wind Ltd. “The results clearly showed that our laser wind sensor technology accurately measured wind speed and direction, and improved the alignment of the turbine against on-coming wind. We believe this will produce benefits for both wind farm operators and turbine manufacturers alike.”
The trial program at NPPD’s Ainsworth Wind Energy Facility is ongoing. The facility has 36 large wind turbines, each capable of generating up to 1.65 megawatts of energy, for a combined total of 59.4 megawatts.
Catch the wind also announced that it has entered into a manufacturing services agreement and will outsource the production and assembly of its Vindicator Laser Wind Sensor (LWS) to BreconRidge Corporation, a provider of collaborative design and manufacturing services.
Under the terms of the manufacturing services agreement signed by both companies, BreconRidge will produce and assemble the Vindicator LWS at its manufacturing facilities in Ottawa, Canada. BreconRidge will also provide technical, engineering, design and other professional services related to the manufacture of the Vindicator LWS.
Earlier this month, Catch the wind signed a research and development agreement with Gamesa. The two companies have mutually agreed to determine the feasibility of using a Vindicator LWS unit mounted on an operating Gamesa G8X 2-megawatt turbine.
