Case Study: Hybrid XT Retrofit on MHI Turbines
ALLETE Clean Energy, a renewable energy company based in Minnesota, U.S., was suffering from reliability issues coupled with long leads times for the turbine control sensors that come stock on their Mitsubishi 600kW turbines. The stock sensors were also minimally heated, so icing events easily overwhelmed them. These problems were causing lost production, revenue hits, and reduced technical availability.
Case Study: Improving Reliability in the Field with Turnkey Solar Resource Assessment System
Working with NRG's complete solar resource assessment system has allowed Wagoner Wind to develop a more static and predictable pricing model that is more competitive than ever.
Characterization + Classification of the Class 1 Anemometer for IEC 61400‐12‐1 Compliance
This white paper documents the results and supporting work to characterize and classify the Class 1 Anemometer according to the guidelines documented in the DTU Wind Energy Department’s Accuwind reports and the IEC 61400‐12‐1 Standard.
Post Calibrating the 40C Anemometer in the SOH Wind Engineering (SOH WE) Wind Tunnel
Two procedures – one simplified, one rigorous – are provided in this white paper, defining the process of evaluating SOH WE post-calibrations of 40C Anemometers initially calibrated at Otech.
Power Performance Testing with Stand-Alone WINDCUBE® Lidar
It is well known that the IEC ‐12‐1:2005 methodology requires the use of a hub height meteorological mast to measure the wind conditions upwind of the turbine(s) being tested. In this white paper, it is argued that ground‐based WINDCUBE Lidar technology provides a very similar input for assessing wind turbine performance in simple terrain sites, mimicking the role of an IEC met mast but with a much higher degree of flexibility and at a much lower cost.
