摘要： 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 features the following: a central control system, which determines a correction value for a local desired value for one or plural wind turbines by way of a first regulator, depending on an actual value of an electric variable before or after the connection point, and a turbine control for at least one wind turbine, which determines a local desired value 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 the sum of the local desired value and the correction value as the total desired value for the electric variable of the wind turbine to be generated.
