Abstract

A wind turbine includes at least two communication protocol handlers (PH), the protocol handlers (PH) generating and interpreting SCADA (Supervisory Control And Data Acquisition) related data according to an associated communication protocol. The at least two protocol handlers (PH) are associated to different communication protocols.

Claims

1. A wind turbine comprising at least two communication protocol handlers, each of said protocol handlers comprising means for generating and interpreting SCADA (Supervisory Control And Data Acquisition) related data according to an associated communication protocol and wherein said at least two protocol handlers are associated to different communication protocols.

2. The wind turbine according to claim 1, wherein each of said at least two protocol handlers comprise means for receipt and transmission of one communication protocol.

3. The wind turbine according to claim 1, wherein said at least two protocol handlers are comprised in a single expanded protocol handler comprising means for generating and interpreting SCADA related data according to several communication protocols.

4. The wind turbine according to claim 3, wherein said expanded protocol handler detects a protocol type of a received data packet by extracting protocol defining data from said received data packet and processes said received data packet according to protocol specific data.

5. The wind turbine according to claim 3, wherein said at least two protocol handlers are merged in said expanded protocol handler comprising means for handling data of at least two different protocols without specific determination of protocol type.

6. The wind turbine according to claim 1, wherein said protocol handlers comprise a SCADA interface.

7. The wind turbine according to claim 1, wherein one of said different communication protocols is based on SOAP-based web services.

8. The wind turbine according to claim 1, wherein one of said at least two different communication protocols is one of the following:

the MMS, the OPC XML-DA, the DNP3, the IEC 60870-5-104 protocol or any combination thereof.

9. The wind turbine according to claim 1, wherein at least one of said protocol handlers is distributed in the wind turbine.

10. The wind turbine according to claim 1, comprising at least one SCADA interface to at least one external SCADA server,

said SCADA interface communicating SCADA related data and said SCADA interface comprises a multi-protocol SCADA interface enabling encoding and decoding of SCADA related data according to at least two different SCADA protocols.

11. The wind turbine according to claim 10, wherein said SCADA server is related to a wind park control station.

12. The wind turbine according to claim 10, wherein said SCADA interface server is located inside the wind turbine.

18. A method of generating and interpreting SCADA related data in a wind turbine according to claim 1, where the generating and interpreting SCADA related data being according to at least two different SCADA related communication protocols, the method comprising the steps of

receiving a data packet in a protocol handler related to said wind turbine,

determining a protocol type of said data packet,

handling the data packet according to said protocol type,

19. The method of generating and interpreting SCADA related data according to claim 18, wherein said method further comprising the step of generating a response according to said protocol type.

20. The method of generating and interpreting SCADA related data according to claim 18, wherein an expanded protocol handler detects the protocol type of a received data packet by extracting protocol defining data from said received data packet and processes said received data packet according to protocol specific data.

21. The method of generating and interpreting SCADA related data according to claim 18, wherein said protocol handler comprises a SCADA interface.

13. A multi protocol SCADA interface related to a wind turbine, the SCADA interface comprising

means for encoding data according to at least two different communication protocols

and further comprising means for decoding data according to at least two different communication protocols.

14. The multi protocol SCADA interface according to claim 13, wherein said at least two different protocols are part of the IEC 61400-25 standard.

15. The multi protocol SCADA interface according to claim 13, wherein one of said at least two different communication protocols is one of the following:

the MMS, the OPC-XML-DA, the DNP3, the IEC 670 5 101/104 protocol or any combination thereof.

16. The multi protocol SCADA interface according to claim 13, wherein one of said different communication protocols is based on SOAP-based web services.

17. The multi protocol SCADA interface according to claim 13, wherein one of said at least two different communication protocols is a GOOSE protocol.
