Abstract: A method of controlling at least one wind turbine blade during the stopping process of the rotor in a wind turbine system is disclosed. The method optimizes the control velocity of the process in response to one or more feedback values of the system and/or one or more feedback values from the surroundings of the system by altering the angular pitch velocity from 10°/sec during the initial stage of the stopping process to 5°/sec at the final stage of the stopping process. A control system and a wind turbine as well as use hereof are also disclosed.

Abstract: Methods of registering events in a wind power system comprising at least two data processors. The data processors of said wind power system are mutually time synchronized. Events are registered in said at least two data processors. The timing of said events registered in different of said at least two data processors is established according to said time synchronization. Events may be registered and preferably analyzed according to a common timing. The event analysis makes it possible to establish an analysis where events of different wind turbines are basically interrelated and where information regarding such interrelation may be important or crucial for establishment of control or fault detection based on correctly timed events from different wind turbines.

Abstract: The invention relates to a central controller adapted for controlling a number of wind turbines. The wind turbines being controlled and monitored by the central controller via a first monitoring and control network and a second monitoring and control network. The term monitoring and control network is in accordance with an embodiment of the invention understood as a data communication network which communicates at least control data for control of wind turbines, but may also communicate monitoring data, i.e. measure data. A typical example of a control of wind turbines is that the central controller sets the power set-point (the power to be produced) of each wind turbine in the wind power plant. The important control signals may be separated from high-bandwidth requiring monitoring data, such as analysis data in the communication network.
