An aeromechanically governed wind turbine: a design study

Abstract

The theoretical model is developed for predicting the aerodynamic performance characteristics of a variable-pitch multi-blade wind turbine. The aerodynamic characteristics are utilized in the design of a self-regulating torque and load system. The optimization of the design, under the influence of severe external perturbations, is investigated in order to select a suitable arrangement in the control system, which consists of a mechanical linkage governor, which will ensure that the wind turbine will continue to operate with good stability characteristics. The study is confined to the aerodynamics and kinematics without considering the influences upon the structural design.
