A statement has been released confirming Siemens Gamesa Renewable Energy (SGRE) testing and approval of nacelle based wind Lidar ‘ZX TM’ from ZX Lidars for the purpose of Power Performance Testing on Siemens Gamesa wind turbines
In connection with a power curve campaign, Siemens Gamesa tested a new technology together with the well-known company ZX Lidars.
Based on the positive results achieved, both on the medium range and long range measurements, Siemens Gamesa Renewable Energy approves the use of the nacelle based Continuous Wave scanning Lidar ‘ZX TM’ from Lidar OEM ZX Lidars for Power Performance Testing. 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 (ed. 1/ed. 2) using a meteorological mast and anemometry installation.
Operational rotor equivalent power curves can also be measured with ZX TM’s unique 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.
