There are two major methods in use: broad range and narrow range variable speed . The former refers to a wide operational range from zero to the full rated speed where the latter refers to a narrow operational range between a fraction (up to ±50%) of synchronous speed. In a geared wind turbine, the generator speed increases with the gear

OverviewTypesHistoryWind power densityEfficiencyDesign and constructionTechnologyWind turbines on public display

Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. They can also include blades or be bladeless. Household-size vertical designs produce less power and are less common. Large three-bladed horizontal-axis wind turbines (HAWT) with the blades upwi

Variable speed wind turbine

A variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies.

Wind turbine generators (WTGs) contain plenty of inertia in their rotating masses, which has great potential for exploitation. Traditionally, WTGs are operated with the rated rotational speed at high wind speeds, which cannot accelerate further to absorb kinetic energy (KE).
