Abstract:
Control method for a wind farm connected to a power grid ( 1 ) and comprising a plurality of generating units ( 2 ). The presence or absence of a voltage disturbance in the grid ( 1 ) is determined with the method, and when the presence of a disturbance is determined, the generating units ( 2 ) are controlled during said presence so that they generate the required power and the wind farm ( 100 ) thereby participates in stabilizing the grid ( 1 ). Furthermore, in the method, when the disappearance of said disturbance is determined, the required power continues to be generated with the generating units ( 2 ) for a limited time interval in order to provide a smooth and controlled transient until the voltage of the grid ( 1 ) stabilizes. Wind farm connected to a grid ( 1 ) and comprising a plurality of generating units ( 2 ).

Claim (Index 2):
Control method for a wind farm according to  claim 1 , wherein an electrical characteristic of the grid ( 1 ) at the point of common coupling (PCC) of the wind farm ( 100 ) and an electrical characteristic at a local point of coupling (LV) associated with each generating unit ( 2 ) of the wind farm ( 100 ) are measured in a recurrent manner, a farm controller ( 5 ) determining the presence of a disturbance if the electrical characteristic measured at the point of common coupling (PCC) exceeds a corresponding predetermined maximum threshold value or is below a corresponding predetermined minimum threshold, or if there is a predetermined number of local controllers ( 3 ) in a local disturbance state, and a local controller ( 3 ) determining the presence of a local disturbance and going into a local disturbance state if the electrical characteristic measured at the corresponding point of coupling (LV) exceeds an associated predetermined maximum threshold value or is below an associated predetermined minimum threshold.
