Abstract
The aim to decrease the price of wind energy compels wind
turbines manufacturers to design yet larger wind power
plants. The large dimensions set also demanding
requirements for the rotor and support structure of the
plant limiting the practical size of the plants. Due to
this limitation, an old concept of IPC have been recently
widely restudied. IPC targets to eliminate periodic loads
resulting from the unsteady aerodynamic force in the
blade by cyclically adjusting the blade pitch angle.
Conventionally, this has been accomplished only on
selected frequencies, because most of the energy
associated to the disturbances is at the rotation
frequency of the rotor. The most used concept, however,
requires time to converge and does not much alleviate
faster disturbances due to turbulent airflow. This paper
suggests a new concept in which each blade pitch angle is
controlled using predictive disturbance data from the two
other blades. The preliminary simulation shows promising
results in both fatigue load reduction and pitch motor
usage
