Constant speed of generator blades
Modern large wind turbines operate at variable speeds. When wind speed falls below the turbine's rated speed, generator torque is used to control the rotor speed to capture as much power as possible. The most power is captured when the is held constant at its optimum value (typically between 6 and 7). This means that rotor speed increases proportional to wind speed. The diff.
