A wind-energy producer says it has selected control software that will boost the output from its fleet of about 800, 1.5 MW wind turbines. NexEra Energy Resources, Juno Beach, Fla., says control software called WindBoost from GE makes it possible to increase output of GE 1.5sle wind turbines by up to 100 kW, thereby boosting output from 1.5 to 1.6 MW. Depending on wind speed and other site atmospheric conditions, the WindBoost control activates to increase the energy produced by each unit. The control software can be remotely turned on and off, providing flexibility to ramp up power production.
The software lets a wind turbine improve operation within the full IEC Type IIB design envelope. This expanded operating mode is expected to produce up to 4% more annual energy output per wind turbine. WindBoost is also said to provide “grid-friendly” features that balance increased output with grid integration requirements of a wind farm.
“Upgrading the turbines in our U.S. fleet gives us the opportunity for increased output without significant hardware additions,” said NextEra Energy Resources VP of wind operations Manny Sanchez.
