Siemens Gamesa Renewable Energy (SGRE) statement of 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 released
In connection with a power curve campaign, Siemens Gamesa has 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.
Importantly and in addition to this, 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 onshore sites with complex veer or shear profiles.
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.
About ZX Lidars (formerly ZephIR Lidar)
ZX Lidars provides industry-leading wind lidar products, ZX 300, ZX 300M and ZX TM for wind energy and meteorological applications. These Lidars deliver accurate wind measurements in both onshore and offshore applications at measurement heights / ranges across the full swept area of the blades of modern wind turbines, and beyond. With more than 10 million hours of operation in the field and over 1000 deployments (and counting), ZX Lidars has pioneered the use of Lidar in the wind industry. The company is proud of the many world firsts it has achieved with customers including: upwind measurements from a turbine nacelle, turbine wake studies, offshore deployments of both fixed and floating wind lidar, an industry-accepted validation process, re-financing and re-powering of a wind farm, successful demonstration of measurement accuracy in a wind tunnel and total wind project financing from a lidar without need for a met mast.
