Grid connection and power converters in modern turbines
The converter reconciles a variable speed rotor with a fixed frequency grid, and it is what lets a wind farm meet modern grid codes.

Pitch and yaw systems, how a turbine faces the wind
Pitch is the turbine's brake and yaw is its heading. Neither makes electricity, both decide whether the machine survives its design life.
Geared turbines compared with direct drive
Gearbox and small generator, or no gearbox and a very large one. Access cost, nacelle mass and supply chain decide, and neither has won.
How a wind turbine drivetrain works
From a rotor turning a few times a minute to grid quality electricity. What sits in the nacelle and why variable speed changed the design.
