    摘要: A tubular tower (11), of a wind energy plant (10) with a current conduction means system (25, 35) for transmitting electrical power from a generator on the tower (11), to a power module at the base of the tower. The current conduction means system (25, 35) has three electrical conductors (27.1, 27.2, 27.3; 37.1, 37.2, 37.3; 45.1, 45.2, 45.3) arranged next to one another. A housing (26, 36, 46) is connected to the inner tower wall at predetermined distances using connecting devices which have electrical cross-sections conducting with the tower wall. The distances between the connecting devices in the longitudinal extent of the tower (11) and the cross-sections of the connecting devices between the housing (26, 36, 46) and the tower wall are dimensioned such that during a fault, the voltage drop between the tower wall and the housing (26, 36, 46) does not exceed a predetermined touch voltage.

    摘要: A method for operating a wind farm comprising several wind turbines that are connected to an internal grid of the wind farm is disclosed. In said method, during a mains failure the electrical consumers of the wind turbines are supplied with electrical energy by a mains replacement supply unit. Each electrical consumer of the wind turbines is assigned to one of at least two groups and according to the group assignment is always switched on by an operation control unit when required, or only switched on if there is a sufficient power reserve. The wind farm is designed to carry out said method.

    摘要: A method for operating a wind farm and to a wind farm is disclosed. When a wind farm and the wind energy installations involve target values for the reactive power being prescribed by a farm regulatory device, said target values for the reactive power ignored by the control units when controlling the respective wind energy installation in the event of a power supply system fault in the power supply system. Only when the power supply system fault has been rectified are said target values considered by the control units again for controlling the respective wind energy installation.

    摘要: A wind energy installation control device includes a wind rotor, a generator driven by the wind rotor, a torque control unit configured to control a torque of the generator, and a control system. The control system includes a detector configured to identify a grid dip and an end of the grid dip, a residual torque transmitter configured to provide a set point for a torque of the generator after identification of the grid dip, and an initializer configured to initialize a component of the torque control unit at the set point. Accordingly, upon return of grid power after a grid dip, the vibration behavior of a wind power system can be significantly improved. Overload of a drive train upon return of grid voltage can thus be reduced.

    摘要: An offshore wind farm can include at least two wind energy installations for generating electrical power from wind, at least two acoustic warning devices, and a visibility measuring device for detecting visibility. After detection of a visibility below a visibility limit value, an activation signal can be applied to the at least two acoustic warning devices. One or more synchronization modules can be provided which determine the points in time of the acoustic signals to be emitted by at least one of the acoustic warning devices in relation to the acoustic signals of the other acoustic warning devices. Accordingly, this facilitates the navigation along an offshore wind farm and enables safe circumnavigation. Also, the impression of a contiguous area can be conveyed to the ships by the synchronized emission of the warning signals.

    摘要: A method for operating a wind turbine (10). The wind turbine (10) is operated with variable rotational speed between predeterminable minimum and maximum rotational speeds. A characteristic variable (51) of an oscillation of the wind turbine (10) is detected. The wind turbine (10) includes a tower (14) and a rotor (13). An open-loop or closed-loop control device (36, 50) provides open-loop control or closed-loop control of the rotational speed of the rotor (13) between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine. A sensor (40) detects a characteristic variable (51) of an oscillation of the wind turbine (10) and the minimum rotational speed is changed depending on the characteristic value (51) of the oscillation. The minimum rotational speed is altered depending on the characteristic variable (51) of the oscillation by the open-loop or closed-loop control device (36, 50).
