The invention relates to a wind turbine () comprising a network arranged for communicating with an external network (), said network of the wind turbine comprising a first sub-network () and a second sub-network (), where the first sub-network () is connectable to the external network () and where the second sub-network () is connectable to and disconnectable from the first network (). Thus, two or more independent networks are created within a single wind turbine to allow communication among the different controllers in the wind turbine along with external communication. The second sub-network is disconnectable from the remaining network, while the first sub-network may have permanent remote connection. This network architecture provides for enhanced flexibility, enhanced security and enhanced functionality.

Network in wind turbine

The present invention relates to a wind turbine facility power supplying arrangement for supplying electrical power to at least a switchgear being able to isolate the wind turbine facility from an electrical network, the wind turbine facility power supplying arrangement comprising a first electrical power supply path able to be provide electrical power to the switchgear and a first power switch able to break said first electrical supply path and able to be controlled for opening and closing. The wind turbine facility power supplying arrangement contains at least another parallel electrical power supply path able to provide electrical power to the switchgear, said parallel electrical supply path been breakable with at least another respective parallel power switch, said parallel power switch being controllable for opening and closing.
