Wind power variation by wind veer characteristics with two wind farms
Scientific Reports, 2023 AbstractTo clarify the wind veer characteristics with height and their effect on the wind turbine power outputs, an investigation was carried out at the wind farms with complex and simple terrains. A 2 MW and a 1.5 MW wind turbine were tested, each having an 80 m tall met mast and a ground lidar to capture wind veering.

Improved Analytical Algorithm for Magnetic Field of End Windings in 300Mvar Synchronous Condenser
IEEE Access, 2021 The magnetic field of end windings affects the leakage reactance of end windings and the eddy current losses of end structures in the large electrical machine. With the rising of single-machine capacity, such effect becomes more obvious.
