Effect of Wind Turbine Classes on the Electricity ...

Dec 31, 2012· In order to select the proper wind turbine class for a specific site, all specifications of a wind turbine class (average speed, gust, and turbulence) must be fulfilled. Taking this into account, in a wind turbine designed for lower wind speeds, the design loads are going to be smaller; therefore its blades are larger and the hub height is taller.

How Much Power Does a Wind Turbine Generate? | Sciencing

Just because a wind turbine has a capacity rating of 1.5 megawatts, that doesn't mean it will produce that much power in practice. Wind turbines commonly produce considerably less than rated capacity, which is the maximum amount of power it could produce if it ran all the time. For example, a 1.5-megawatt wind turbine with an efficiency factor ...
