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.

Claims

1. A wind power plant, comprising:

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 at least one 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 through the at least one data transmitter;

wherein the second DSL modem is connected with the second data contact device; and

wherein the data transmitter is provided between the first and second data contact devices.

2. The wind power plant according to claim 1 wherein the data transmitter comprises at least one slip ring having at least one sliding contact.

3. The wind power plant according to claim 2 wherein the at least one slip ring comprises at least two sliding contacts.

4. The wind power plant according to claim 3 wherein at least four sliding contacts are provided.

5. The wind power plant according to claim 1 wherein at least two redundant data connections are provided.

6. The wind power plant according to claim 3 wherein at least two of said sliding contacts each are connected in parallel.

7. The wind power plant according to claim 1 wherein at least one of the first and/or second DSL modems is configured as an ADSL modem.

8. The wind power plant according to claim 1 wherein at least one of the first and/or second DSL modems is configured as an SDSL modem and in particular an SHDSL modem.

9. The wind power plant according to claim 8 wherein data is transmitted in a frequency range below 10 MHz and in particular below 2 MHz.

10. The wind power plant according to claim 9 wherein data is transmitted in a frequency range of 50 kHz to 1500 kHz.

11. The wind power plant according to claim 1 having at least one supporting structure and at least one rotor blade provided rotatable thereat and at least one sensor at the rotor blade, wherein the supporting structure is provided with a control device which via the at least one data connection is in data connection with the at least one sensor in the rotor blade.
