The very first practical use of wind lidar by ZephIR occurred in 2003, with the system deployed on a Nordex turbine performing measurements upwind from the nacelle. In order to verify its performance claims, ZephIR Lidar embarked on a ten-year research programme to illustrate the performance attributes when compared to more traditional techniques, such as tall meteorological (met) masts and even wind tunnels used to calibrate cup anemometers themselves. Ten years on, and ZephIR’s continuous-wave (CW) lidar technology continues to be developed and is now gaining increasing acceptance in its original application of optimising wind turbine generator performance.
