Abstract

An apparatus and method is disclosed for over-rating a wind turbine using turbulence prediction. Weather forecast information is used to determine whether there is a risk of turbulent conditions occurring at the site of the wind turbine. The wind turbine is over-rated if turbulent conditions are not predicted, and conversely over-rating is cancelled or reduced if turbulent conditions are expected. This allows an increase in the annual energy production of the wind turbine to be realised. The weather forecast information may be combined with real time measurements of operating conditions to supplement the predictions.

Description

technical field

[0001] The present invention relates to means for overrating wind turbines using turbulence forecasts. In particular, the present invention relates to means for over-rating control of wind turbines, and to methods and apparatus for enabling one or more wind turbines of a wind farm to be over-rated for short periods of time to generate electrical energy based on predicted and current turbulence . Background technique

[0002] Defined in IEC 61400: The rated power of a wind turbine is the maximum continuous electrical power output that the wind turbine is designed to achieve under normal operating and external conditions. Large commercial wind turbines are typically designed for a 20-year lifetime, and their rated power output is taken into account over that lifetime.

[0003] It is desirable for a wind turbine to operate in an overrated mode of operation because this increases the annual energy production (AEP) of the turbine. In other words, more electrici...
