Ventera's VT 10 Turbine Testing and Results

Ventera's VT10 wind turbine. Text Version

As part of the National Renewable Energy Laboratory and U.S. Department of Energy (NREL/DOE) Independent Testing project, NREL is testing Ventera's VT10 small wind turbine at the National Wind Technology Center (NWTC). The VT10 is a horizontal-axis downwind, three-bladed turbine rated at 10 kilowatts (kW). Its diameter is 6.7 meters, and it is mounted on a lattice tower with a hub height of 21.7 meters. The VT10 uses a single-phase, grid-connected, permanent-magnet generator that operates at 240 volts AC.
