摘要： The invention relates to a wind turbine comprising a machine housing (12) equipped with a rotor (14), which is mounted to pivot on a sub-structure (10). Wind parameters and an electromechanical quantity are determined by means of measuring devices (21, 22, 23). To enable the machine housing (12) to track the wind, the wind turbine is equipped with a pivoting device (11) comprising a controller (8). The wind turbine is also equipped with a calibration module (2), which is configured to determine an effective mass of the electromechanical quantity using the wind speed. In addition, the turbine comprises an evaluation device (4) comprising a classifier (40), which is used to form a first average value for a first class, for which the wind direction is positive and a second average value for a second class, for which the wind direction is negative. A difference is determined by means of a comparator and a calibration signal is emitted to the controller (8) of the pivoting device (11). The invention permits an autonomous calibration of the controller (8) for the tracking of the machine housing (12) and thus reduces the risk of an erroneous positioning of the rotor (14) in relation to the wind direction, irrespective of the prevailing wind conditions. The invention is particularly stable in relation to variable wind forces and directions, especially in the presence of gusts.

摘要： A method for operating at least one wind turbine with a rotor and an electric generator coupled to the rotor for delivering electrical power into an energy distribution system with the aid of a control device ensures that the wind turbine operates within its operating range. The wind turbine is controlled in response to the change of a system operating parameter and for a period of time, in such a manner that a higher power is fed into the system than belongs to the operating range of the steady-state operation. The same conditions also apply to a method for providing control power or primary control power for an electric energy generator and distributor system to which a multiplicity of power stations including wind turbines is connected, and to a wind turbine.

摘要： The invention relates to a management system for the operation of a wind turbine, which regulates the power output of the turbine. The wind turbine includes a rotor with at least one rotor blade that is positioned at an adjustable angle to the rotor. The management system regulates the rotor speed within a predefined wind speed range by varying the rotor blade angle in order to set a nominal output and reduces the output in excess of a defined wind-speed-dependent threshold value. The threshold value is a defined rotor blade limiting angle.

摘要： A method and system for monitoring the operation of a wind energy installation. State data relating to the wind energy installation is recorded and discrepancies are found between the state data and an associated comparison value. A failure probability of the wind energy installation is determined based on any found discrepancy. An availability value for the wind energy installation is determined from the ratio of the actually produced amount of electrical energy to the total amount of energy which can potentially be produced. The availability value and the failure probability are then combined to form a repair priority, which is associated with the wind energy installation. Accordingly, more uniform operation of wind energy installations can be achieved.

摘要： A method for controlling a converter of a wind energy installation. The converter is connected to a rotor of a doubly-fed asynchronous generator for feeding electrical power into an electrical grid and comprises a generator-side inverter, a grid-side inverter, and at least one converter regulator for regulating and/or controlling currents emitted from at least one of the inverters to at least one of the generator and the electrical grid. The method includes detecting a change in electrical voltage present in at least one of emitted real currents and emitted reactive currents at one of the inverters, determining whether the detected change corresponds to a predetermined change, and changing nominal values of at least one of real currents to be emitted and reactive currents to be emitted from the other inverter if the detected change corresponds to the predetermined change.

摘要： A wind energy installation can include a generator which is driven by a rotor and generates electrical power in a multiphase manner for feeding into a network, a converter which is connected to the generator and to the network, and a control system which interacts with the converter and includes a negative sequence system regulation mechanism. The negative sequence system regulation mechanism can include a phase control module configured to determine an electrical variable of the negative sequence system according to the phase. Accordingly, an available current can be provided according to the operating situation for active power or idle power in the negative sequence system regulation mechanism. The negative sequence system regulation mechanism can thus help stabilize the network in the event of asymmetrical network conditions. Also, this relates to a correspondingly equipped wind park and an operating method.

摘要： A wind turbine includes a rotor having adjustable rotor blades for driving a generator and an adjusting device for the rotor blades provided with an actuator that comprises at least an excitation winding. The adjusting device includes a torque-reducing device that automatically reduces drag torque of the actuator. The torque-reducing device includes a current divider that switches the current through the excitation winding in such a manner that the current flows completely through the excitation coil when the motor is in operation and the current only partly flows through the excitation coil when coasting (slip operation). As a result, when coasting, the magnetization of the excitation winding is reduced about the adjusting device, whereby the increase of the speed torque characteristic curve can be determined, thus improving the ratio of the adjusting device when coasting.
