Abstract
Systems and methods for reducing dynamic loading in an idled wind power unit include sensing at least one parameter indicative of dynamic loading and executing a reduced torque brake mode, which may comprise a controlled brake and brake-release sequence, with the turbine braking system when the sensed parameter exceeds a selected value. The reduced torque brake mode absorbs energy and reduces dynamic loading thereby.
