SYSTEM AND METHOD OF CONTROLLING A WIND TURBINE IN A WIND POWERPLANT

摘要

The invention relates to a central controller (CC) adapted for controlling a number of wind turbines (WT), said wind turbines (WT) are controlled and monitored by said central controller (CC) via a first monitoring and control network (MCNl) and a second monitoring and control network (MCN2). 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. A further advantageous feature of the invention is also that the important control signals may be separated from high-bandwidth requiring monitoring data, such as analysis data in the communication network.
