Abstract

The primary purpose in constructing equivalents is to represent a portion of a network containing many buses but having only a few "boundary buses" by a reduced network containing only the boundary buses and, perhaps, a few selected buses from within the original sub-network. The equivalent constructed gives an exact reproduction of the self and transfer impedances of the external system as seen from its boundary buses. PowerFactory’s network reduction algorithm produces an equivalent representation of the reduced part of the network and calculates its parameters. This equivalent re-presentation is valid for both load flow and short-circuit calculations, including asymmetrical faults (that is, single-phase faults).
