Description:
The proper work of vertical wind turbine Savonius typed may be negatively influenced by very high wind speed. Usually the wind turbine speed is limited by means of a brake. The turbine speed is limited, but the spindle of the turbine is still subject of increased torque. The paper proposes a new, innovative technical solution that does not counteract increasing the turbine speed above a limit value, but prevents it. The new concept is based on dividing the blade of the turbine into several parallel vertical strips, properly displayed, as to form the shape of a conventional blade. Each strip can rotate against its own vertical axis, to change its orientation in vertical plane. This brings the benefit that when the turbine speed tends to overcome a certain value (dangerous for the turbine) the strips orientation changes, and the surface of the blade becomes a non-continuous one. The area of the blade that faces to the wind reduces, and prevents increasing the turbine speed. When w...
