[POSTER] Variation of the production loss coefficient as a function of yaw misalignment
An EPSILINE LiDAR, installed on a GE 2.5xl wind turbine, measures the wind ahead of the rotor. Measurements were taken during 3 months. The static alignment value of the wind turbine was changed automatically every 30 minutes with four set points: 7°, 0°, -7°, -14°. The data was then classified into four alignment operation classes: 0°, -5°, -10° and -15° (see figure 4) after which the calculations were performed. For each power curve, an AEP is calculated using the Weibull distribution of the site and uncertainties are calculated according to the methodology of the IEC 61400-12-1:2017 standard . The Cpp is then calculated using each AEP value.
