Control systems for horizontal-axis wind turbines
Abstract
Control requirements for wind turbine systems and problems of conventional controls are discussed. Alternates to pitch control for large horizontal-axis wind turbines are changing pitch of blade tips or use of ailerons or spoilers. Studies was conducted to determine feasibility of using such control systems on the NASA MOD-O machine. Results show that either ailerons or spoilers can provide control necessary to limit turbine power in high wind conditions. An aileron system is recommended for the present application, based upon the ability of ailerons to provide self-starting and added power at low wind speed conditions. The preliminary design study including aileron component sizing and maximum hinge moments was completed and ailerons were fabricated for testing on the MOD-O turbine.
