Aggregate induction motor load. This model  is used to represent a fraction of an ordinary load as "induction motor load".  It allows load that is treated as ordinary constant power in power flow analysis to be represented by an induction motor in dynamic simulation.  Either a "one-cage" or "two-cage" model of the induction machine can be modeled.  Magnetic saturation is not modeled.<br /></p><p><br /></p><p>This model is intended for representation of aggregations of many motors dispersed through a load represented at a high voltage bus but where there is no information on the characteristics of individual motors.<br /></p>
