Computer Modeling Wind Turbine Blades with Optimal Parameters

Abstract

This paper aims to create efficient techniques to optimize the weight of wind turbine blades. A new mathematical model has been introduced, applying boundary element methods. Hypersingular integral equations have been used to calculate the dynamic pressure acting on the blade. The finite Hadamard part of the hypersingular integral has been received analytically over an arbitrary flat polygon. A revised version of the nonlinear programming method has been developed, which incorporates adaptive management techniques to optimize the procedures. The proposed optimization method uses several methods, called hybrids. A criterion has been specified by which the most effective hybrids are selected for the current search for an extremum. This criterion includes information characterizing a changing situation. The computer simulation results indicate that the wind turbine blade with the minimal weight has been achieved. Additionally, the proposed method will be extended to include the strength and dynamic analysis of wind turbines with a vertical axis of rotation.
