Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces electricity (typically variable-frequency AC, which is then converted via power electronics/inverters so it can be used.

Unlike a traditional generator, a DFIG is fed with electrical power on both the rotor and stator sides, allowing for two-way power flow.

The swept area of a wind turbine is the area in square feet of the rotor, also known as the “capture area”. It is calculated by measuring the blade length and using the formula A = πr².
