constant that, when multiplied by the angular velocity of the rotor poles with

MW x s. For a motor, it includes the motor plus its mechanical load. Conventional
units are PU on the generator MVA base, usually expressed as MW x s / MVA or
just s. This value is used in the accelerating power reference frame for operator
training simulator solutions. Typical value = 3.
