The deterioration prediction system and method includes a dynamic model of the mechanical device and a state estimator to predict deterioration in a mechanical device. The dynamic model includes a plurality of evolving health states that describe the performance of the mechanical device. The dynamic model can be implemented such that several distinct factors contribute the evolution of the health states. These factors can include damage accumulation, interaction between components in the device, deviation from design conditions, and the influence of discrete events. In one embodiment, the dynamic model uses a Poisson distribution to model the rate of damage accumulation in the mechanical device.

Abstract: The present invention relates to a method of controlling the aerodynamic load of a wind turbine's blades individually in such a way that the dynamic aerodynamic loads on the turbine are reduced and power production is optimised. In general the present invention will improve the overall stability of the turbine leading to reduce fatigue loads, reduced extreme loads during operation and reduced risk of blade-tower interaction. In particular preferred embodiment of the invention, flow properties are measured locally on the different blades or in front of the blades and from these measurements the pitch angle settings are changed, in other ways changing the aerodynamic properties, for the blades through a control unit.
