A wind farm includes a plurality of wind energy installations, a transfer point at which electrical energy produced by the wind energy installations is transferred to a public electricity grid system and for which nominal values are preset, and a measurement sensor configured to measure electrical actual values at the transfer point. The wind farm also includes a master regulator associated with an upper control level and configured to use upper nominal values and upper actual values at the upper control level to determine a preset for a lower control level, and a plurality of submaster regulators associated with the lower control level and configured to use the preset as a lower nominal value and, on the basis of the lower nominal value and a lower actual value, determine presets for the wind energy installations. A high level of control accuracy can thus be achieved even in large wind farms.

Wind farm and method for controlling a wind farm

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.

Method for configuring a windfarm network

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.

Method for optimizing the operation of a wind turbine

A wind turbine generator includes at least one rotating member, at least one stationary member, and a clearance gap control system. The stationary member is positioned such that a clearance gap is defined between a portion of the rotating member and a portion of the stationary member. The clearance gap is configured to facilitate transmitting a controllable magnetic flux therethrough. The control system includes at least one clearance gap measurement assembly, at least one power converter, and at least one controller. The controller is coupled in electronic data communication with the assembly and the converter and is configured to modulate a dimension of the gap by modulating the flux.

Method and apparatus for controlling rotary machines

The method for controlling a first wind energy turbine of a wind park comprising multiple wind energy turbines connected to the grid, in situations where the first energy turbine operates substantially at zero energy output level, comprises the steps of determining whether at least one of the other wind energy turbines of the wind park is operated above a predetermined energy output level, and if at least one of the other wind energy turbines of the wind park is operated above the predetermined energy output level, maintaining connection of the first wind energy turbine to the grid.

Method for controlling a wind energy turbine of a wind park comprising multiple wind energy turbines

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.
