DNV GL verifies nacelle-mounted ZephIR Lidar wind measurements
New nacelle Lidar test site fully operational An independent performance verification of a nacelle-mounted ZephIR Lidar has been undertaken by DNV GL on the test site in Janneby, Germany which demonstrates the product is compliant with best-practice guidelines developed in the EUDP UniTTe programmes – widely regarded and accepted as industry benchmarks for installations of turbine-mounted Remote Sensing Devices (RSDs). In the verification, the ZephIR DM nacelle-mounted lidar was mounted horizontally on a raised platform (FW-MM) – 180m away from…

New IEC standard sees acceptance for wind lidars in wind turbine power curve testing
The international standards and conformity assessment body for all fields of electrotechnology, the International Electrotechnical Commission (IEC), has published a new standard to deliver the technical basis for the acceptance of lidar measurements for wind turbine power performance testing and wind resource assessments. The release of the new standard, IEC 61400-12-1:2017, is considered a major milestone in lidar’s growing maturity, formally allowing lidar as a supplementary or alternative measurement technique to mast-mounted cup anemometers. ZephIR 300…
