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.

Management system for operating a wind energy plant and method using the management system

A control device has a control drive for operating a valve or some other apparatus, for example an adjustment device for the pitch angle of a wind rotor, by means of a control element. This control drive is associated with an emergency operating device, via which the control element can be reset in the event of a disturbance, essentially independently of the operation of the control drive. This emergency operating device has an energy store, whose stored energy can be released for resetting. The emergency operating device has a piston, on one side of which the energy store acts and on the other side of which a pressure in a pressure area acts, which pressure area can be connected via a switching valve to a tank or the like, in order to release the energy stored in the energy store. In this case, the piston is designed such that it moves the control element in a resetting direction when the pressure in the pressure is relieved.

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.

A contactless energy supply for electrical consumers mounted on the mobile part of a linear motor is provided, the energy supply being provided without additional voltage sources. A higher frequency energy supply field is superposed over the propulsion field, the energy supply field being inductively decoupled using the energy transmitting interface of the secondary part, and supplying consumers mounted on the secondary part with energy.

An actuating drive for a rotor blade in a wind power installation is provided with an electric motor and a frequency converter which has a rectifier that is to be fed from a power supply system, a link connected to the rectifier, and a d.c.-to-a.c. inverter for feeding the motor, the link carrying a specified nominal operating voltage in a network-fed normal operation of the frequency converter. Furthermore, an auxiliary energy supply device is provided that is connected to the link. The auxiliary energy supply device includes and energy store which makes available a support voltage that amounts to less than 80% of the nominal operating voltage of the link. A diode is connected between the energy store and the link, and is arranged, with regard to its forward direction, in such a way that it feeds a support voltage from the energy store into the link if the link voltage falls below the support voltage. The diode prevents a current flow between the energy store and the link if the link voltage is greater than the support voltage. A charging device for the energy store has a lower charging voltage than the nominal operating voltage of the link.
