More Information
Summary:A torsional protection system (300) and method (500) is provided for protecting a wind turbine from undesired torsional oscillations. The torsional protection system includes a detection processing stage (302) that isolates energy contained within a measured signal to a frequency band of interest. An input to the detection processing stage is obtained from at least one component in the wind turbine. A protection logic stage (304) compares the energy to a threshold level to get an indication of an amount of the energy that is above a predetermined threshold. The torsional content of the signal can be measured and monitored so that if the torsional content exceeds the predetermined threshold for a predetermined time an alarm or trip signal can be generated.
