Liberty Wind Turbine
Encyclopedia
The 2.5 MW Liberty Wind Turbine is the largest wind turbine
manufactured in the United States. The turbine was developed through a partnership with U.S. Department of Energy and its National Renewable Energy Laboratory
for Clipper Windpower
.
The design of the turbine is meant meant to reduce problems with power train components that have been experienced in other machines. A two ton crane within the nacelle simplifies maintenance thereby reducing costs. The size and weight of the liberty allow it to be constructed with crane of the same capacity as used with most 1.5 MW turbines.
Commercial sales for the new Liberty turbine started in June 2006.
Liberty Wind Turbine uses as standard an 80 metres tall tower. The rotor diametre is for version C89 89 metres, for C93 93 metres, for C96 96 metres and 99 metres for C99. Blade lengths are 43.2m for C89, 45.2m for C93, 46.7m for C96 and 48.2m for C96. Liberty Wind Turbine has 4 generators using permanent magnets. Each of them delivers 660 kW at 1133 rpm at a voltage of 1320 V DC.
Wind turbine
A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy is used to drive machinery, such as for grinding grain or...
