Abstract

A system and method (200) for protecting an idling wind turbine power system (10) from damage during loss of grid power. The wind turbine power system has a plurality of rotor blades (22). The method (200) includes monitoring an incoming wind direction (66) at the wind turbine power system (10). When the incoming wind direction (66) is changing at a predetermined attack angle, the method (200) also includes rotating at least one of the rotor blades of the wind turbine power system to a pitch angle that is offset from a feather position by a predetermined number of degrees to reduce and/or eliminate flutter phenomenon from occurring.
