Governing in wind turbines is primarily achieved through pitch control, which adjusts the angle of the blades to maintain a constant rotational speed of the generator's shaft, ensuring electricity is generated at a fixed frequency. Unlike hydroturbines that regulate water flow rate, wind turbines utilize mechanisms such as flywheels and clutches to stabilize rotational speed, although these are less common. The flywheel stores kinetic energy, allowing for consistent output even when wind speeds fluctuate. The discussion highlights the efficiency of pitch control over mechanical clutches in energy management.
