Abstract

A wind turbine comprises a rotor comprising radially outwardly extending blades which are twisted in cross-sectional shape so as to achieve a constant angle of attack. Additionally, the blades are connected at their outer ends to a peripheral rotor ring which is arranged to engage and drive a rotary member of a generation system of the wind turbine that is mounted at a fixed angular position relative to the rotor ring. The wind turbine is operated in a manner which includes determining for each of a plurality of wind speeds a relationship between rotation rate and optimum power output and varying the power output of the generation system to change the load on the rotor to maintain the rotation rate at or adjacent the rotation rate which provides the optimum power output.
