The Output power of wind turbine is determined by wind speed. The Output power can be adjusted by controlling the generator speed and pitch angle of wind turbine. When the wind speed below the wind turbine rated, the output power of generator can be maximized by controlling the generator speed at point of maximum power coefficient. When the wind speed above the wind turbine rated, output power ...

This paper presents two methods for load angle determination for salient-pole synchronous generator. The first method uses optical encoder to detect the rotor position. In some cases the end of the rotor shaft is not free to be used and mounting of an encoder is impossible. Therefore, the second method proposes estimation of the load angle based on the measured electrical values that have been ...

With the increasing electrical energy demands in aviation propulsion systems, increase onboard generators’ power density is inevitable. During flight, forces coming from gearbox or gyroscopic generated by flight manoeuvres like take-off and landing can act on generators' bearings, which lead to wear fatigue bearings. Utilizing radial force control concept machine relieve loads bearings t...
