Pitch Angle Misalignment Correction Based on Benchmarking and Laser Scanner Measurement in Wind Farms
In addition to human error, manufacturing tolerances for blades and hubs cause pitch angle misalignment in wind turbines. As a consequence, a significant number of turbines used by existing wind farms experience power production loss and a reduced turbine lifetime. Existing techniques, such as photometric technology and laser-based methods, have been used in the wind industry for on-field pitch measurements. However, in some cases, regular techniques have difficulty achieving good and accurate measurements of pitch angle settings, resulting in pitch angle errors that require cost-effective correction on wind farms. Here, the authors present a novel patented method based on laser scanner measurements. The authors applied this new method and achieved successful improvements in the Annual Energy Production of various wind farms. This technique is a benchmarking-based approach for pitch angle calibration. Two case studies are introduced to demonstrate the effectiveness of the pitch angle calibration method to yield Annual Energy Production increase. ; This work is funded by the Council of Gipuzkoa (Gipuzkoako Foru Aldundia, Basque Country, Spain) within the R&D subsidy for the project DIANEMOS on the identification of defective anemometers in wind turbines, and the University of the Basque Country (UPV/EHU, GIU 17/002).
