RWE has kicked off power performance testing of turbines at the Galloper offshore wind farm off east England.
The German company is utilizing the nacelle based lidar ‘ZX TM’ from ZX Lidars for the job.
ZX TM allows the power curve of wind turbines to be measured and verified as a function of the hub height wind speed and replaces the need for using a meteorological mast and anemometry installation as described in the IEC61400-12-1:2017, said ZX.
Operational rotor equivalent power curves can also be measured with ZX TM’s 50 points around the full rotor swept area, particularly important for turbines with larger rotor diameters offshore and on sites with complex veer or shear profiles onshore, added the company.
In October 2020 Siemens Gamesa approved the use of the nacelle based continuous wave scanning lidar ‘ZX TM’ from ZX Lidars for power performance testing.
