Attribute
Public Float
  damping

Details:
GUIDBasedOn={95E0BBB7-E24D-4ace-B7F5-6D8FD46473ED}
Notes: Damping torque coefficient, a proportionality constant that, when multiplied by the angular velocity of the rotor poles with respect to the magnetic field (frequency), results in the damping torque.  This value is often zero when the sources of damping torques (generator damper windings, load damping effects, etc.) are modeled in detail.
Public Seconds
  inertia

Details:
GUIDBasedOn={0EF1D9E9-EF40-452c-80A0-202D4473A5E0}
Notes: Inertia constant of generator or motor and mechanical load.  Must be greater than zero.  This is the specification for the stored energy in the rotating mass when operating at rated speed. For a generator, this includes the generator plus all other elements (turbine, exciter) on the same shaft and has units of MW-sec. For a motor, it includes the motor plus its mechanical load. Conventional units are per unit on the generator MVA base, usually expressed as MW-second./MVA or just second.   This value is used in the accelerating power reference frame for  operator training simulator solutions.
