June 23-24 we participated at WindEurope’s Resource Assessment & Analysis of Operating Wind Farms in Brussels
René M. M. Slot did the following two presentations, which you can download by clicking at the titles:
Standard operation of wind farms often requires curtailment of individual turbines, which is accomplished through noise modes, resulting in reduced power output and sound emission. A development is ongoing where noise modes are applied at a higher and higher resolution with differentiation wind direction, wind speed and other relevant climatic variables. This calls for a corresponding refinement of modern optimization tools to solve curtailment strategies.
Increasing numbers of onshore wind turbines are reaching the end of their design lifetime and the owners therefore face the difficult decision whether to repower, decommission or lifetime extend their assets. Here we show for the V52 at Risø how the remaining useful fatigue lifetime may be estimated using a surrogate model which is trained by a generic turbine model with comparable specifications. The presented method provide a basis for improved decision support for wind turbine owners when assets approach the design lifetime and critical investment decisions about possible future operation must be made.
