The suitable hybrid configuration of Darrieus lift‐type and Savonius drag‐type rotors for stand‐alone wind turbine‐generator systems is discussed using our dynamic simulation model. Two types of hybrid configurations are taken up. Type A installs the Savonius rotor inside the Darrieus rotor and Type B installs the Savonius rotor outside the Darrieus rotor. The computed results of the output characteristics and the dynamic behavior of the system operated at the maximum power coefficient points show that Type A, which has fine operating behavior to wind speed changes and can be compactly designed because of a shorter rotational axis, is an effective way for stand‐alone small‐scale systems. © 2005 Wiley Periodicals, Inc.
