Farm Loads:

Farmloads is a project that further develops the initial studies in which equivalent loads were calculated with the so-called actuator disc and actuator line methods. The actuator disc method is relatively fast, which means that large parks can be calculated on supercomputers available to the research group.

By evaluating loads on lines (the actuator line method) or on a section of a disk surface (the actuator disc method) at each time step, a time series of loads is obtained. This time series is evaluated and equivalent forces are calculated. The properties of time series can be linked to different types of wear damage in different components and types of damage. Initial investigations together with Vattenfall show good agreement between calculated loads and detected blade damage.
