Method of controlling a wind energy system and wind speed sensor free wind energy system
First Claim
1. A method for controlling a wind energy system, the wind energy system comprising a rotor, the method comprising:
- determining an effective wind speed incident on the rotor, taking into account load on the rotor exerted by wind; and
determining an operational condition of the wind energy system based on the effective wind speed,wherein the determining the effective wind speed comprises calculating the effective wind speed differently for predetermined different ranges of wind speeds.

Abstract
A method for controlling a wind energy system is provided wherein the method comprises determining the effective wind speed taking into account the load on the rotor blades of said wind energy system exerted by the wind is provided. A computer-readable medium is provided that provides instructions which when executed by a computing platform cause the computing platform to perform operations wherein the operations include the method according to embodiments described herein. Further, a wind energy system having a calculation unit adapted for calculating the effective wind speed by taking into account the load on the rotor blades of said wind energy system exerted by the wind is provided. Further, a wind speed sensor free wind energy system having a generator for generating electric energy and a controller for shutting down and/or starting the electric energy generation in dependence of the wind speed is provided.
