The cut-out speed marks the upper boundary of safe operation, a high-wind threshold typically around 25 meters per second. As wind speed increases between the cut-in and the rated speed, the turbine enters a region of accelerating power production, where the generator and power electronics work in concert to capture an ever-greater portion of the wind's energy, demonstrating the initial phase of the power curve's steep ascent.

This critical performance map plots the relationship between instantaneous wind speed at the hub height and the resulting electrical output, serving as the primary benchmark for assessing a turbine's efficiency and energy production potential. Shedding Excess: The Role of Pitch Control The transition from the steep power curve slope to the rated plateau is a masterclass in engineering control.
Cut-Out Speed and The End of the Curve No power curve is linear indefinitely, and the graph eventually descends towards zero. At the heart of the curve lies the concept of the cut-in speed, the minimum wind velocity at which the turbine begins to generate power, typically ranging from 3 to 4 meters per second.

Innovations in direct-drive generators and power electronics have also improved low-wind performance and reduced losses. To maintain this constant power output, the turbine employs sophisticated pitch control, adjusting the angle of the blades to shed excess wind energy and prevent overloading the drivetrain and generator.
