Question

What should be the minimum wind speed to maintain the required motion of the turbine in a wind energy farm

Answer 1

In general, wind speeds are as follows: 8 kph (2 m/s) minimum is required to start rotating most small wind turbines. 12.6 kph (3.5 m/s) is the typical cut-in speed, when a small turbine starts generating power. 36–54 kph (10–15 m/s) produces maximum generation power......

Answer 2

The correct answer for your question is 12.6 Kph

The average power generation of a wind turbine depends on the average speed of wind in a certain region. The point of generation varies according to the various regions. Typically a small wind turbine requires only 2m/s speed of wind to initiate spin but it requires (12.6 Kph)3.5 m/s speed of wind to start generating power.

Thresh hold capacity of wind turbine is 25m/s speed of wind. Here the wind turbine may subjected to break or stop when the wind speed exceeds.

10-15 m/s wind speed is the speed that requires to generate maximum power.
