Abstract: A method for damping torsional oscillations in a power production plant includes a drive train, a rotor fitted to a rotor-side end of the drive train, and a generator driven via the drive train and fitted to a generator-side end of the drive train. By using at least one angular position of the drive train at the generator-side end thereof, a torsional moment acting on the drive train is determined and used to control the generator.

Abstract: A turbine power plant is disclosed for generating electrical energy from a fluid flow, comprising a gondola rotatably mounted on a pedestal, particularly a tower, comprising a drivetrain, designed for converting the energy applied to the rotor into electrical energy by a rotor driven by the fluid flow and by means of functional components designed for supporting the rotor and/or for supporting the gearbox and/or for converting energy. At least one of the functional components listed above has an operationally fixed connection for transmitting static and dynamic loads from the drivetrain to the tower.

Abstract: A drive train for harnessing the energy of a fluid flow includes a rotor configured to be driven by the fluid flow, a transmission that is connected to the rotor at the input end, either directly or indirectly via the rotor shaft or other components, and a generator that is connected to the transmission at the output end. A lubricant system supplies lubricant to one of the drive train components as well as to another drive train component.

Abstract: A management system for a wind energy plant including at least one control unit, and a method using the management system are disclosed. The management system is used to coordinate component modules of the wind energy plant with vibration damping modules and/or load reduction modules, wherein a sensor system supplies data of the operating states of the component modules for a system analysis. For this purpose, reactive vibrations and/or predictive forecasts of vibrations of the wind energy plant, and predictive disturbance variables are registered, and the vibration damping modules and/or load reduction modules in the control unit are activated, wherein an actuator carries out damping measures and/or load reduction measures on the component modules in accordance with the vibration damping modules and/or load reduction modules of the control unit.

Abstract: A stationary energy generation plant includes a control device that serves to control current and energy flow. The energy generation plant includes at least one mechanically driven rotor and a generator mechanically coupled to the rotor. To this end, power electronics operationally connected to the generator enable variable energy flow from the rotor through the generator and the power electronics to a load. In order to compensate for vibrational loads on the generator side, at least one current control is made possible by means of a first intermediate circuit storage of the power electronics. In order to compensate for mechanical vibrational loads and transients of a drivetrain, an energy flow control is provided by means of at least one additional second intermediate circuit storage disposed in the power electronics and having a multiple of the storage capacity of the first intermediate circuit storage.
