The compensation system of this invention is adapted to modify the rotor blade pitch angle signal received from a central controller and output a compensated rotor blade pitch angle signal to the actuator for each blade independently in order to counteract the loads on the blade caused by non-uniformity of the wind-field, with the benefit of reducing the asymmetric rotor loads. The individual compensation system for each rotor blade pitch angle does not depend on either the load measurements for any other blade or on the compensated rotor blade pitch angle for any other blade other than through the common collective rotor blade pitch angle signal provided by the central controller. The compensation system of this invention is therefore a reactive system which greatly increases the service life of the installation.
