ZX TM from ZX Lidars gets Siemens Gamesa approval

0

Siemens Gamesa Renewable Energy (SGRE) has approved nacelle based wind lidar ‘ZX TM’ from ZX Lidars.

The lidar will be used to provide Power Performance Testing on Siemens Gamesa wind turbines.

Prior to the approval, Siemens Gamesa tested the new technology together with ZX Lidars.

Based on the positive results achieved, both on the medium range and long range measurements, Siemens Gamesa approved the use of the nacelle based continuous wave scanning lidar ‘ZX TM’.

This specific lidar – ZX TM – allows the power curve of SGRE wind turbines to be measured and verified as a function of the Hub Height wind speed and may be, when agreed with the customer, used instead of the procedure described in the IEC61400-12-1:2017 using a meteorological mast and anemometry installation.

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, the company explained.
