Holistically optimised individual blade angle adjustment in field and model tests

In order to further reduce the levellised cost of electricity from wind energy, modern wind turbines have ever larger rotor diameters. In order to tap further wind resources, it is also necessary to install wind turbines at increasingly demanding locations with a wide variety of wind conditions. Both developments mean that modern rotor blades are exposed to considerable variations in wind and inflow conditions. For example, the inflow conditions on a rotor blade can vary considerably when travelling through pronounced vertical wind profiles during a rotor revolution. The individual pitch control (IPC) offers the possibility to optimally align each blade of the wind energy position under these conditions. This project aims to develop optimised strategies for controlling this individual blade angle adjustment. The aim of this holistic optimisation is to identify site- and turbine-specific control strategies that minimise peak loads and noise emissions while increasing the power yield.
