Understanding optimum minimum pitch at a wind farm
Optimum minimum pitch depends on many wind farm specific factors including typical air density, turbulence, blade surface conditions, and blade modifications. The pitch angle settings in region 2 of the power curve impact the angle of attack and efficiency of the rotor blades. WindESCo analysis evaluates if different minimum pitch angle settings would improve turbine performance.
Pitch schedule settings determine the behavior of the power curve in Region 2.5 by determining the angle of attack and efficiency of the rotor blades. WindESCo analysis evaluates if pitch schedule settings would improve turbine performance -or- efficiency in different operating conditions.
