Wind power assembly

Abstract

A wind power plant having a nacelle and a rotor and a data transmission system which is suitable and equipped for transmitting data from a first data contact device in the nacelle through a data transmitter to a second data contact device in the rotor which is rotatable relative to the first data contact device. The first data contact device is connected with a first DSL modem which is connected with a second DSL modem via the data transmitter. The second DSL modem is connected with the second data contact device. The data transmitter is provided between the first and second data contact devices.

Description

Technical field [0001] The present invention relates to a wind power plant having a cabin, a hub, and a data transmission system, which is particularly used to transmit operating and control data or other data between the contacts of the cabin and the contacts of the hub rotating around it. Background technique [0002] There are various wind power plants in the prior art, in which data is transmitted from a first data contact in the cabin to a second data contact that can move relative to the cabin and rotate around the hub. Normally, the data connection is serial and is achieved through a slip ring, which is used to transmit data from a stationary cabin to a rotating hub, and vice versa. These slip ring transducers can have multiple contacts, allowing two, three or more conductive connections to coexist via the slip ring transducer at the same time. [0003] These slip ring transducers are used, for example, in wind power plants to transmit current and data. One known design of...

Problems solved by technology

When the same radio channel is selected, if the situation worsens, the data transmission between the central controller of the wind power plant to the hub or the rotor can no longer be guaranteed

[0015] However, if there is no data connection between the controller and the spinner for a period of time, the wind farm will shut down for safety reasons

A failure of the radio or wireless connection would then have the potential to cause considerable financial damage to the workers, as the wind power plant would be shut down unnecessarily simply due to a reduction in the reliability of the data transmission

In other wireless systems, the reliability of operation cannot be fully guaranteed

Although Bluetooth can basically achieve undisturbed signal transmission through frequency hopping, interference or failure can still occur

In addition, the rate at which it can transmit data is not enough

[0016] Although the shortened build-up distance makes a radio connection seem more suitable, it is not always possible to fully guarantee that data exchange via radio will be undisturbed, since it is not foreseeable that workers will install web cameras or similar equipment

Even brief disturbances in radio data transmission can cause considerable economic damage in the event of a wind power plant shutdown

And it has been proven that in the presence of radio disturbances it becomes difficult to find the cause of the problem
