Renewable energy consultant Natural Power announced the release of a lidar wind profiler that has been tested and developed with GL Garrad Hassan at a lidar test site in the UK. The ZephlR 300 has many features of past ZephIR ‘175’ systems and has been tested via IEC equivalent power performance measurements, extensive onshore / offshore campaigns, and tall mast verifications up to 193 m.
However, the ZephlR 300 is smaller and lighter than its predecessors, measures at ten heights, and requires less power. The new model is also of single pod construction capable of operating from -40°C through to +50°C. It has robust, high-specification connections and is fully CE compliant including approved true Class 1 eye-safe laser classification (IEC 60825-1) and EMC compliance (EN61236 Industrial and EN55022 Class A standards).
The manufacturer says correlations during 2010 at the lidar test site saw excellent agreement between mast and ZephIR across all heights with less than <1% difference in gradients and R2 values, quite close to the optimum value of 1.0. Testing has also demonstrated close to 100% constant data recovery (availability) rates with increasing height, from 10 to 200 m. Measurements at 300 m have also been taken and will be available on the device.
Alex Woodward, Product Development Manager at Natural Power says, “ZephIR 300 has been subjected to extensive reliability and safety testing over the past months. All systems are validated against a calibrated 90-m met mast providing the traceability required by wind engineers. In addition, Natural Power possess over 25 GW of technical project experience from site prospecting to quantitative wind resource assessments – a background which ensures all of our product innovations are fit for market. ZephIR 300 truly is designed by wind engineers for wind engineers.”
