Objective
Objectives
Fatigue monitoring will be applied to three wind turbines of a single type operating under varying external conditions in order to gather "footprints" of the measured load quantities. These will be qualitatively compared to such "footprints" assembled from load time series measurement campaigns as well as from calculated load data in order to learn about the relevant quantities for parametric fatigue load monitoring. The fatigue monitoring method will be refined and applied to the already installed measurements. The aim is to cover practical methods for commercial application on wind turbines components and to deliver practical information for manufacturers and certification bodies at low costs.
Technical Approach
- Application of the fatigue load monitoring method on three wind turbines of the same type in order to collect "footprints" for the fatigue loads experienced by the three machines in their specific external conditions, i.e. stand alone, wind farm & complex terrain conditions.
- Identification of a set of parameters that describe a "footprint". - Search for parameters that can be taken as measures for validity of a monitored "footprint" / measured fatigue load spectrum.
- Refinement of the employed fatigue monitoring technique to allow for parametric measurements according to the parameters identified. - Employment of the principle of "footprints" gained from fatigue monitoring in order to
- quantify the wind farm effects on a wind turbine's fatigue loading - quantify complex terrain effects on a turbine's fatigue loading. - Investigation of the importance of low cycle fatigue of wind turbines. - Relation of the "footprint"-findings to results from earlier theoretical research work and a qualitative contribution to the improvement of specifications on wind farm and complex terrain operation.
Expected Achievements and Exploitation
The expected outcome will be a cost effective fatigue loading assessment method for wind turbines. Combining the fatigue load measurement with power curve measurements, the gained "footprint" of the fatigue loading during the power curve measurement will help the manufacturer in the verification of his fatigue design. Results gained from prototypes may be brought in in the certification process and in the optimization of the serial production. This will promote economic design and simultaneously improve safety. This will be of interest to consulting enterprises as well as certifying bodies. The project will contribute with some more puzzle stones for the picture of fatigue loading in wind farms and complex terrain.
Meteorological and operational data can be used together with the load spectra for verification of prediction models for wind farm lay-out and complex terrain models concerning wind turbine loads. General results will be brought into the discussions on national and international guidelines and the normalized data bases will be offered on request.
