AUTOMATIC STORM PROTECTION CONTROL FOR WIND ENERGY SYSTEM

摘要

Title of the Invention AUTOMATIC STORM PROTECTION CONTROL FOR WIND ENERGY SYSTEM A wind energy plant is protected against damage from high winds by permitting the propeller assembly thereof to fold with respect to the tail assembly of the plant when the wind velocity with respect to the plant exceeds a predetermined value. Return of the propeller assembly to a wind facing orientation is controlled to prevent oscillating or whipping in gusty or turbulent winds. A safety system is included to control plant shutdown, and automatically shuts down the plant if the plant is being subjected to excessive vibration.
