Question

What should be the minimum wind speed for the satisfactory working of a wind-powered electric generator?

Answer 1

Wind speed fluctuates, which has an impact on wind electricity generation capacity and operating characteristics. In general, wind speeds are as follows: 8 kph (2 m/s) minimum is required to start rotating most small wind turbines.At 90 kph (25 m/s) maximum, the turbine is stopped or braked (cut-out speed).
