Method for operating wind energy plant, involves transmitting driving torque to generator over power train, where generator provides predetermined generator torque acting opposite driving torque

摘要

The method involves transmitting driving torques (10,16) to a generator over a power train. The generator provides predetermined generator torques (12,22) acting opposite the driving torque and is connected to a grid. The generator torque is controlled depending on a phase position of a torsional vibration of the power train after an abrupt voltage change in the grid.
