Abstract
The mathematical model of a small-scale counter-rotating Savonius wind turbine is constructed and studied. Rotors are located one above the other. Their shafts are coaxial. The shaft of one Savonius rotor carries the rotor of an electric generator, and the shaft of the other carries the stator of the same generator. Savonius rotors are supposed to rotate in opposite directions. Thus, the relative angular speed of the generator rotor with respect to the stator is increased. The generator is connected to the local electrical circuit. Operation modes corresponding to autorotations of Savonius rotors in the wind flow are discussed. The trapped power in such regimes is estimated. It is shown that the chosen design of the wind turbine is characterized by the same maximum power coefficient as a classical single Savonius rotor, but with double increase of the relative angular speed of the generator rotor with respect to the stator. Parameters of the system that provide maximum trapped power coefficient are found.
