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

When a wind turbine appears to explode, the underlying cause typically involves a combination of mechanical failure, fire, and structural collapse rather than a true chemical explosion.

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.

The workings of a wind turbine are much different, except that instead of using a fossil fuel heat to boil water and generate steam, the wind is used to directly spin the turbine blades to get the generator turning and to get electricity produced.
