Abstract: A wind farm monitoring and control system, includes at least one wind farm, at least one intelligent management server connectable to the at least one wind farm via a data communication network, and at least one wind farm configuration tool related to the intelligent management server for establishment of connection(s) to the at least one wind farm. A system for monitoring and control of wind farms is provided. The monitoring and control is performed so that it is possible to monitor and control several wind farms homogeneously. Hereby it is possible to monitor and control different wind farms simultaneously with a uniform output and it is moreover possible to compare data from the wind farms.

Abstract: The invention relates to a method of registering events in a wind power system comprising at least two data processors, wherein the data processors of said wind power system are mutually time synchronized, wherein events are registered in said at least two data processors, wherein the timing of said events registered in different of said at least two data processors is established according to said time synchronization. According to an advantageous embodiment of the invention, events may be registered and preferably analyzed according to a common timing. This analyzing makes it possible to establish an analysis where events of different wind turbines are basically interrelated and where information regarding such interrelation is 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 method for controlling a wind power plant comprising a plurality of wind turbines being operatively connected to a plant collector grid, the method comprising the steps of providing a desired power reference signal; determining the power production of the wind power plant, and generating an actual power reference signal in response thereto; comparing the desired power reference signal with the actual power reference signal, and performing one of the following steps: 1) applying a first filter characteristic as part of a generation of a wind turbine power reference if the desired power reference signal exceeds the actual power reference signal; or 2) applying a second filter characteristic as part of the generation of the wind turbine power reference if the actual power reference signal exceeds the desired power reference signal, wherein the first filter characteristic is different from the second filter characteristic. The invention also relates to a power plant controller, a wind power plant and a computer program product.

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.
