Control system for a wind power plant with hydrodynamic gear

摘要

A wind power plant connectable to an electric grid is provided that has at least three control levels. A controller controls an angular position of the rotor blades and/or controls a setting of the reaction member of the hydrodynamic speed transformer and/or controls the power electronics of the generator. The controller is provided with predetermined setpoint characteristics depending on operating states of the wind power plant and/or the electric grid or characteristics of the wind.
