Session 4: How to best extend life expectancy

Session chair: Christian Jourdain, head of marketing and communications, services, Gamesa

In the US, Denmark, Germany and Spain, more than 50% of the current installed based will be over 15 years old in 2020, making life extension a real business opportunity, but also a technical challenge. To develop life extension solutions and guarantee a safe operation of wind assets, the industry has to understand aging mechanisms, using structural models and identifying aging contributors.

Speakers in this session will share their findings in physics of failure approach, model based reasoning, fatigue dominant contributors in wind farms, combination of source of data such as inspections, load and SCADA measurement data, and numerical simulation, and finally how this methodology can be certified.

Session 5: Innovative techniques for enhanced performance

Session chair: Jørgen Højstrup, CEO, Højstrup Wind Energy

It is a well-established fact that there is a general tendency for some wind farms to produce less energy than expected. Whereas some of the reasons for the underperformance can be found in the wind resource assessment which of course you cannot do anything about after the wind farm is built, then there seems to be potential for significant improvements of the performance of the existing turbines, in some cases by relatively simple adjustments of the operating behaviour of the turbines.

It is no simple matter to verify that the turbines are in fact producing less energy than they should because of the large amount of variables influencing the power production. In this session we will look at different ways of identifying underperformance, finding the sources of the underperformance and finally fixing the problem.

One paper present a slightly different way of analysing power performance data, two papers deal with the analysis of large amounts of data from wind farms to identify underperformance and to find the sources of the underperformance, three papers shows measurements of some of the specific sources of underperformance, pitch angle misalignment and yaw angle misalignment.
