Class cim:AsynchronousMachineDynamics

Class [owl:Class]

Asynchronous machine whose behaviour is described by reference to a standard model expressed in either time constant reactance form or equivalent circuit form or by definition of a user-defined model. Parameter Notes: Asynchronous machine parameters such as Xl, Xs etc. are actually used as inductances (L) in the model, but are commonly referred to as reactances since, at nominal frequency, the per unit values are the same. However, some references use the symbol L instead of X.
