The Deutsche WindGuard Consulting GmbH testing laboratory has been accredited for the calibration of nacelle mounted lidars.
Accredited according to DIN EN ISO/IEC 17025, the laboratory can now calibrate all kinds of wind remote sensing devices.
According to Deutsche WindGuard Consulting, nacelle lidars have gained in importance in the last years – especially with regards to the verification of warranted power curves.
“Measurements with nacelle lidars have the great advantage over classical power curve tests that there’s no need for the installation of a met mast,” said Dr. Klaus Franke , head of Deutsche WindGuard Consulting’s calibration laboratory for remote sensing devices.
“Especially in offshore measurements, nacelle lidars are a cost-efficient alternative.”
While nacelle mounted lidars are not yet included in IEC standards, they are widely used for power curve verification measurements, the laboratory said.
“We are part of an IEC task group that develops an IEC standard for the use of nacelle lidars in the frame of wind measurements, which will be published sometime next year,” Franke said.
For each measurement, traceable sensors are absolutely essential, according to Deutsche WindGuard Consulting. The calibrations are conducted on the existing WindGuard test field.
