Embodiment Construction
[0085] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the nacelle 104 . In operation the rotor 106 is brought into rotational motion by the wind to drive a generator in the nacelle 104 .
[0086] figure 2 A wind farm 112 is shown as an example with three wind energy installations 100 , which can be identical or different. Three wind energy installations 100 thus represent in principle any number of wind energy installations of wind park 112 . Wind energy installation 100 supplies its power, ie in particular the current it generates, via park grid 114 . In this case, the respectively generated currents or powers of the individual wind energy installations 100 are added and a transformer 116 is usually provided, which steps up the voltage in the field and then feeds it into the supply network 120 at a feed point 118 In , the feed point is also commonly referred t...

The invention relates to a method for controlling the restoration of an electrical supply network (120), wherein: the electrical supply network (120) has a first network section (302) and at least onefurther network section (302); at least one wind farm (304) is connected to the first network section (302); the wind farm (304) is controllable via a wind farm control station (320); the first network section (302) is coupled to the at least one further network section (342) via at least one switching device (340) in order to transmit electrical power between the network sections (302, 342); theat least one switching device (340) is designed to disconnect the first network section (302) from the at least one further network section (342) in the event of a fault; a network control centre isprovided to control the at least one switching device (342); the first network section (302) is disconnected from the at least one further network section (342) by the at least one switching device (340) in the event of a fault in which a network fault acting on the first network section (302) occurs; the wind farm control station (320) exchanges data with the network control centre (324) via a control station link (326); the control station link (326) is a fail-safe communication link between the wind farm control station (320) and the network control centre (324) and can be operated independently of the electrical supply network (120), in particular even if there is a fault in the first network section (302); the wind farm (304) receives data from the network control centre (324) via a wind farm link (328); the wind farm link (328) is a fail-safe communication link between the wind farm (304) and the network control centre (324) and can be operated independently of the electrical supply network (120), in particular even if there is a fault in the first network section (302); and further data which are not transmitted via the control station link (326) and not via the wind farm link (328) are transmitted via a further data link (322, 332) as long as the latter has not failed.
Description
technical field [0001] The invention relates to a method for controlling a grid re-establishment of an electrical supply network. Furthermore, the invention relates to a communication device for controlling re-establishment of a grid. The invention also relates to a wind farm having a plurality of wind energy installations which are used in such a method for grid reconstruction with control. Background technique [0002] A supply grid can be composed of a plurality of grid segments. If a disturbance occurs in a grid section which endangers the stability of the grid section or already causes instability in the grid section, it is expediently and usually also provided that the grid section is connected to the remaining The power supply network is separated. This achieves that the disturbance does not yet impair other parts of the power supply network or even the power supply network as a whole. In principle, however, other reasons for such a separation of a network segment...
