SYSTEMS FOR LOAD REDUCTION IN A TOWER OF AN IDLED WIND-POWER UNIT AND METHODS THEREOF

摘要

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.
