Class: SynchronousMachineDynamics
_Synchronous machine whose behaviour is described by reference to a standard model expressed in one of the following forms: _
_- simplified (or classical), where a group of generators or motors is not modelled in detail; _
_- detailed, in equivalent circuit form; _
_- detailed, in time constant reactance form; or _
_- by definition of a user-defined model. _
_It is a common practice to represent small generators by a negative load rather than by a dynamic generator model when performing dynamics simulations. In this case, a SynchronousMachine in the static model is not represented by anything in the dynamics model, instead it is treated as an ordinary load. _

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

load damping effects, etc.) are modelled in detail. Typical value = 0.

(> 0). 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 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.
