Abstract
A method of controlling a wind turbine in response to an overvoltage event in an electricity grid to which the wind turbine is connected is provided, which method includes the steps of controlling at least one auxiliary device to increase its consumption of reactive power, wherein an auxiliary device is a device used during normal operation of the wind turbine; and/or controlling at least one reactive power generating device to decrease its generation of reactive power, wherein a reactive power generating device is a device that generates reactive power during normal operation of the wind turbine. An overvoltage response arrangement adapted for controlling a wind turbine in response to an overvoltage event in an electricity grid to which the wind turbine is connected is also provided. A wind turbine having an overvoltage response arrangement and a wind park are also provided.
