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 3):
Control method for a wind farm according to  claim 2 , wherein the wind farm ( 100 ) further comprises at least one compensation unit ( 4 ) for providing reactive current and/or power to the grid ( 1 ) when required and a local controller ( 6 ) associated to said compensation unit ( 4 ), an electrical characteristic of the grid ( 1 ) at the point of common coupling (PCC) of the wind farm ( 100 ), an electrical characteristic at a point of coupling (LV) associated with each generating unit ( 2 ) of the wind farm ( 100 ), and an electrical characteristic at the point of coupling (PC) of the reactive compensator ( 4 ) to the grid ( 1 ) being measured in a recurrent manner, the 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 ,  6 ) in a local disturbance state, and a local controller ( 3 ,  6 ) 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, PC) exceeds a corresponding associated predetermined maximum threshold value or is below a corresponding associated predetermined minimum threshold.
