Abstract: A method for use in controlling a wind turbine generator (1) based on a condition of a power converter or a component forming part of a power converter in the wind turbine generator (1). The method comprises determining a condition of the power converter or the component forming part of a power converter, then comparing the condition to a predetermined threshold and modifying an operational parameter of the wind turbine generator (1) if the condition substantially equals or exceeds the predetermined threshold. In particular, the invention proposes the wind turbine generator (1) is derated if the condition of the power converter or the component forming part of a power converter substantially equals or exceeds the predetermined threshold.
