Wind turbines have become a popular choice for renewable energy generation, especially in areas with consistent breezes. Each wind turbine is designed to have a specific cut-in (startup) wind speed where the rotor begins to turn and generate electricity. Below the cut-in speed, the wind is not strong enough to rotate the blades and generator. By lowering the cut-in speed (while retaining high wind speed performance) will result in the turbine generating more power over a period of time.
A wind turbine can incorporate an Orbital Traction Adjustable Speed Drive (ASD) between the turbine and the generator to control the speed ratio. The ASD acts like a continuously variable transmission (CVT), allowing for an infinite number of speed ratios that can be used in both high and low wind speed conditions. The ASD will allow for a lower cut-in speed by reducing the torque required on the rotor. As the wind speed increases, the ASD would shift to a higher gear and allow the generator to generate electricity at its optimum speed.
The benefits of using an ASD with a wind turbine are:
