Claim:
1. A method for preventing excessive loading on a wind turbine, the method comprising: determining a current wind turbine parameter indicative of a wind turbine thrust using at least one operating condition via a processor, the operating condition indicative of wind turbine operation; storing the current wind turbine parameter in a memory store over a predetermined time period; calculating a standard deviation of a plurality of the stored current wind turbine parameters via the processor; determining a future wind turbine parameter we of the wind turbine thrust via the processor; calculating, via the processor, a maximum wind turbine parameter representing a steady-state load from turbine operation and dynamically fluctuating loads due to environmental conditions comprising a function of the standard deviation of the plurality of stored wind turbine parameters added to the future wind turbine parameter; controlling the wind turbine, via a controller, based on a difference between the maximum wind turbine parameter and a parameter setpoint to prevent excessive loading on the wind turbine.
