Abstract: A method for automatically configuring a local network in a windfarm is provided, the method including the steps of (a) automatically assigning an IP address to a device connected to the local windfarm network, (b) automatically receiving an identifier tag from the device, and (c) relating the automatically assigned IP address of the device to a specific wind turbine in the windfarm which is identified by said identifier tag.

Abstract: A method for optimizing the operation of a wind turbine is provided, the method comprising the steps of: (a) adjusting at least one control parameter of said wind turbine to a predetermined starting value; (b) measuring at least one response variable of said wind turbine and at least one further variable indicative of an ambient condition of the wind turbine; (c) repeating step (b) N times, wherein N is a predetermined integer, wherein said at least one control parameter is varied at each repetition; (d) determining a measured relation between the at least one control parameter with respect to the at least one response variable and the at least one further variable indicative of an ambient condition; (e) determining an optimized value of said at least one control parameter with respect to said response variable from said measured relation; (f) adjusting a set point of said at least one control parameter to said optimized value.

Abstract: A the rotor for a wind energy turbine includes a hub and at least one rotor blade connected to the hub. The rotor also includes comprises at least one sensor for sensing at least one physical value of the rotor, e.g. mechanical stress, and a power supply for supplying electrical power to the at least one sensor. The power supply includes an electromechanical converter for converting mechanical energy from vibrations of the rotor when subjected to wind loads, e.g. during operation of the wind energy turbine, into electrical energy for supplying to the at least one sensor.
