Abstract

The BOHG wind turbine generator systems with a vertical lift-device rotational axis and with a surface-variable airscrew are principally aimed at making such systems more reliable and inexpensive. They are characterized in that they operate efficiently even under extreme climatic conditions. They require neither wind direction systems nor towers or nacelles of any great height, irrespective of whether they are mini or mega wind turbine generator systems. The nominal dimensions ø and H (diameter and height of the rotor) of a BOHG wind turbine generator system are two variables that are dependent on the power demand and the historical average wind speed at the installation site. The BOHG wind turbine generator systems can achieve a very high coefficient of performance of 95%, and even up to 98%, thanks to the building design, which provides very innovative aspects such as: • the floating of the rotor and the generator cores, even if they weigh several tens of tonnes • the weight (mass) of the systems of the: brakes, transmissions and stators of the generators rest on the floors of the tower or of the nacelle • the operating surface of the rotor blades can independently vary such that they offer virtually no resistance to movement when they are directed against the wind direction • each rotor blade contains, in its longitudinal axis, a counterweight which contributes inter alia to the stability of the dynamic variation/fluctuations during the rotational movement.
