The conformability of rated power output of the system to wind conditions is investigated theoretically with our simulation model on a wind turbine-generator system consisting of a Darrieus-Savonius hybrid wind turbine and a load alternator. As a computed result of the dynamic behavior of the systems which are operated at a constant tip speed ratio, it is clear that a large-scale system is effective with net extracting power in catching wind power at high velocities. However, an excessively large-scale systems do not always have an advantage over small-scale systems because the rotational speed allowed by the strength of the blade and excessively high velocities limits the power extraction. Regarding the effective power coefficient, it is clarified that a small-scale system is more effective than a large-scale one because of the dynamic characteristics of the system. Hence, it is shown that a conformable rated power output of the system exists for each wind condition.
