Wind turbine, wind turbine communication system, and method for operating a bus system

A wind turbine communication system, comprising:

• a plurality of CAN nodes which are coupled to at least one electrical or electronic component of a wind turbine, and
• a plurality of CAN distributing units, a first CAN distributing unit of the plurality of CAN distributing units is coupled via a first communication segment to a CAN node of the plurality of CAN nodes and via a second communication segment to a second CAN distributing unit of the plurality of CAN distributing units,
• wherein a data communication takes place via the first communication segment based on a first CAN protocol that is a standard CAN protocol,
• wherein a data communication takes place via the second communication segment based on a second CAN protocol which is different from the standard CAN protocol.

A method for communication between at least two electrical or electronic components of a wind turbine that are coupled to a CAN node, wherein the wind turbine has a communication system with a plurality of CAN nodes and a plurality of CAN distributor units, the method comprising:

• communicating, by a first CAN distributor unit of the plurality of CAN distributor units, via a first communication segment with one of the plurality of the CAN nodes,
• communicating, by the first CAN distributor unit of the plurality of CAN distributor units, via a second communication segment with a second CAN distributor unit of the plurality of CAN distributor units,
• wherein communicating via the first communication segment is made using a first CAN protocol which corresponds to a standard CAN protocol, and
• wherein communicating via the second communication segment is made using a second CAN protocol which differs from the standard CAN protocol.
