Deutsche WindGuard accredited for calibrating Lidar

209

Deutsche WindGuard Consulting GmbH is now accredited according to DIN EN ISO/IEC 17025 for the calibration of nacelle-mounted Lidars. The calibration laboratory can now calibrate all kinds of wind remote sensing devices and completes its range of services in this department.

Nacelle Lidars have gained in importance in the last years — especially with regard 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.

“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. The calibrations are conducted on the existing WindGuard test field.
