The wind industry needs accurate wind measurements at higher heights. Tritons have recorded millions of hours of wind data on thousands of wind energy projects around the world. Triton is the wind industry’s most thoroughly validated remote sensing system.
Ongoing studies, including the most recent studies done by Ecofys, provide confidence in Triton’s performance from one unit to another. Like earlier studies, the Ecofys studies show excellent correlation between the Triton and met mast wind speed measurements. An Executive Summary of the Ecofys studies is available here, and the full reports are available to our customers on request. Register for the Executive summary and others here: https://goo.gl/L5EV7g
Ecofys: Triton Verification Studies
The Triton, a ground-based SoDAR remote sensing system, measures wind at and above the hub height of today’s wind turbines. Triton is used to supplement or replace measurements from met towers in assessment and operational settings. Wind energy developers use Triton data in project financing, energy assessments, and to reduce the uncertainty of resource assessments in conjunction with tower data. Wind power plant operators use Triton in forecasting, relative power curve testing, and wake analysis. Triton is the most thoroughly validated remote sensing system in the wind industry. Ecofys, a leading wind energy consultancy, released two verification studies of the Triton in 2016 under project number WIEWT15389. These studies demonstrate Triton’s consistency from one unit to another.
A few other findings
- These tests covered a full three months of collocated met mast measurements from spring to summer 2016; “the resulting dataset is significantly larger than the minimum required, providing a robust basis for uncertainty calculations.”
- “The overall SoDAR and met mast recordings showed consistent, highly-correlated measurements with slopes near unity.”
- “The calculated uncertainty in the SoDAR wind speed measurements is low, in line with first-class anemometry.”
- “Sensitivity tests of the wind speed deviation revealed that the wind speed deviation shows no significant linear correlation to external conditions: vertical wind speed, horizontal wind speed, turbulence intensity or rain. This indicates that the SoDAR is insensitive to these factors.”
- “The SODAR measurements were also validated against NORSEWiND criteria for LiDAR remote sensors and meets the Ecofys WTTS acceptance thresholds for field measurements.”
- “The SODAR will measure the long-term mean wind speeds with accuracy comparable to cup anemometry in flat terrain.” Triton at Ecofys Wind Turbine Testing Service’s Test Site Lelystad, Netherlands. Triton is the most thoroughly validated remote sensing system in the wind industry. New verification studies by leading wind energy consultant Ecofys demonstrate Triton’s consistency from one unit to another.
