PO214: Rotor-plane inflow reconstruction using dual scanning lidars for blade load assessment
Xingzhou Zhou, Tech-support engineer, Movelaser
Abstract
The inflow at the rotor plane of wind turbines exhibits significant spatial and temporal variability, particularly under complex terrain conditions. Transient wind structures can induce uneven blade loading, posing structural risks that exceed standard design assumptions. Conventional meteorological masts are expensive and spatially limited, while single remote sensing systems are insufficient to resolve the full inflow in front of the rotor plane. To address these challenges, this study applied a dual doppler scanning lidar system configured as a virtual meteorological mast, enabling multi-height profiling and rotor-plane inflow reconstruction for real-time blade loads assessment. The investigation comprised two stages. First, the dual-lidar configuration was validated against a reference mast using a white-box testing approach. By applying triangulation and vector synthesis of radial wind speeds from the dual lidars, horizontal wind speed and direction were derived at 60 m, 97 m, and 135 m, achieving deviations within 0.2 m/s and 4°, respectively. Building on this foundation, a yaw-dependent scanning strategy was developed, allowing the azimuth and elevation angles of the lidar beams to adapt dynamically to the turbine orientation. The results confirm that dual scanning lidars can not only substitute for conventional masts in vertical profiling but also reconstruct rotor-scale inflow characteristics for blade load evaluation. This capability provides a practical solution for operating and monitoring wind turbines in complex terrain.
