A method of activating an ice removal system of a wind turbine comprises: monitoring the output power of the wind turbine; monitoring an output from an ice sensor provided on the wind turbine indicative of an atmospheric icing condition; and activating the ice-removal system when the output power is below an expected output power and the output from the ice sensor indicates that an atmospheric icing condition has ended.

Controller and method for a wind turbine

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.

System and method of controlling a wind turbine in a wind power plant

The invention relates to a system of at least two distributed wind turbines where the at least two wind turbines communicate via a data communication network, the data communication network communicates monitoring and control data (MCD) to and from the at least two wind turbines (WT), the data communication network communicates power control related data (PCRD) to and from the at least two wind turbines (WT), the power control related data (PCRD) has higher transmission priority than a subset of the monitoring and control data (MCD) and where the transmission priority is defined in relation to a protocol.
