Patent ID: 8332076

Claim:
A wind farm with plural wind turbines, which are connectible to a farm grid, that is in turn connectible to an electricity supply mains via a connection point, wherein the wind farm comprises: a central control system ( 10 ), which determines a correction value ( 26 , 28 ) for a local desired value ( 54 ) for one or plural wind turbines by way of a first regulator ( 12 , 12 B), depending on an actual value of an electric variable before or after the connection point; and a turbine control ( 32 ) for at least one wind turbine, which determines a local desired value ( 54 ) for an electric variable to be generated by the wind turbine by way of a second regulator, depending on an actual value of an electric variable measured in the farm grid, wherein the turbine control determines a total desired value ( 60 ) for the electric variable of the wind turbine to be generated by summing the local desired value ( 54 ) and the correction value ( 36 ).
