Myth about minimum wind speed

In general, one prefers a wind turbine that is primarily based on two parameters, namely the lowest wind speed at which the power plant begins to generate electricity at rated power. The latter parameters will be discussed further, and now we will eliminate the myth about minimum wind speed. In most cases, this cut-in wind speed is 2.5 - 3.5 m / s, which is a completely worthless parameter. Wind does not have the energy that wind can use at such speeds. Imagine a wind turbine with a wind speed of 3.5 m/s of 6 m (this is a large enough series of small generators) with an impeller diameter of only 120 watts! Therefore, the minimum wind speed parameter is simply a drop in the sea. This power is consumed by the network inverter itself, and no one enters the network.
