System and method of controlling a wind turbine in a wind power plant
First Claim
1. A central controller adapted for controlling wind turbines, wherein said central controller is connected to and is configured to transmit data to and receive data from each of said wind turbines via a first network and a second network, and wherein control data for control of each of the wind turbines is distributed between at least the first network and the second network, the control data comprising critical power control data, wherein the critical power control data is communicated to and from said wind turbines exclusively via a selected one of the first and second networks.

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.

16. A method of controlling a wind turbine in a wind power plant, whereby a central controller performs a monitoring and control procedure, the method comprising:
-
identifying high priority data by prioritizing at least one of;
control related data and monitoring related data based on a time sensitivity attribute associated with the control and monitoring related data;transmitting the high priority data between said central controller and the wind turbine using only a first network, the first network connecting said wind turbine and said central controller; and transmitting at least a portion of the control and monitoring related data between said central controller and the wind turbine via a second network connecting said wind turbine and said central controller. - View Dependent Claims (17, 18, 19)
