A wind farm comprises at least one wind turbine and the combination of a voltage controller and a tap-changing transformer arranged to control a reactive power output of the wind farm. The tap-changing transformer is arranged to transform an output voltage of the wind farm at a predetermined position in the network. The controller has a first input arranged to provide a measure of the output voltage of the wind farm at the predetermined position and a second input representative of a desired reference voltage set by a network operator. The controller is arranged to monitor the input and generate a first output to the tap-changing transformer to change its tap setting and keep the voltage at the predetermined position within predetermined limits, and to generate a second output to control the reactive power output of the wind farm. |
