Abstract
A method for determining a limit value of a wind turbine reference operational variable is described The wind turbine being connected to a connection node to which a utility grid is connected. The method includes: obtaining a first input signal indicative of a connection node limit voltage; obtaining a second input signal indicative of a connection node voltage; and determining the limit value of the wind turbine reference operational variable based on the first signal and the second signal. Further a corresponding arrangement is described.
