Wind Plant Wake Management
GE introduces wind plant wake management, a farm-level application to harness the power of the Industrial Internet to drive higher output, improve services productivity, and create new revenue streams for customers.
Wind plant wake management is a controls application that reduces wake losses, that occur when a velocity deficit created behind a turbine rotor reduces the wind available at downwind turbines, lowering plant-level energy production.
Applications and Benefits
The increase in annual energy production from wind plant wake management is site dependent, but will typically range from 0.5%-2%.
Wind plant wake management is intended to operate alongside existing wind plant control platforms and will not require hardware changes for sites with existing SCADA servers.
Utilizing advanced algorithms and control tools developed at GE’s Global Research Center, wind plant wake management integrates data from turbine-level and plant-level controls with real-time wind characteristics and micrositing information, then adjusts individual turbine operational parameters such as pitch angle, tip speed ratio, and rotor speed in order to reduce wake losses and increase plant level energy output.
