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 and a system are for determining of the compatibility of control software, which is designed for standard parameters, with a wind energy installation which is operated using operating parameters. The method is an automatic method in which the operating parameters of the wind energy installation and the standard parameters of the control software are first transmitted to a computation unit. The computation unit determines discrepancies between the operating parameters and the standard parameters. A decision on compatibility is made on the basis of the discrepancies. The system includes a logic module which is designed to make the decision. This method makes it easier to automatically update the control software for a wind energy installation. There is no longer any need to manually check the compatibility of the new version of the control software before the new version of the control software can be installed.

摘要： A method for regulating a wind energy installation including a rotor-driven generator, a converter connected to the generator, and a controller that regulates power emitted into an energy transmission system to within a limit value involves determining a maximum current value in a connection path, determining a current reserve value for power emitted into an energy transmission system, and determining a correction value for following a limit value of the emitted power from the maximum current value and the current reserve value. The wind energy installation and the method for its regulation also includes the use of a limitation device configured to set a phase angle between an emitted current and voltage of an electrical system in response to a selection signal in such a way that primarily active power or primarily reactive power is fed into the energy transmission system when the maximum current value is reached.

摘要： The invention relates to a method of operating a wind farm intended for connection to an electric power network, which wind farm includes at least three wind turbine generator systems. At least one actual value for a wind speed or a parameter associated with wind speed is determined for each wind turbine generator system which are divided at least temporarily into predetermined groups. A first disconnect value is assigned to one group of wind turbine generator systems and a second different disconnect value is assigned to a second group of wind turbine generator systems. Actual values are assigned to disconnect values, and compared thereto. When the actual value exceeds the disconnect value the associated group of wind turbine generator systems is automatically disconnected.

摘要： The invention relates to a method for operating a wind energy system wherein when a first settable boundary value (G1) is reached by a first parameter (M1) a process is automatically started whose course is monitored by measuring a second parameter (M2). By comparing the measured values of the second parameter (M2) with a second settable boundary value (G2), the first settable boundary value is changed upon reaching the second boundary value (G2) by the second parameter (M2).

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.
