A Generalized Model For Electric Distribution Systems
H.J. Robinson, T. W. Reddoch, J.W. Klein · 2005
A generalized mathematical model is constructed of single-phase induction machines employed within a three-phase distribution system. It is shown that this composite model retains single-phase distribution detail and describes the intrinsic characteristics of the single-phase induction generator. Power system fault(s) and circuit breaker response(s) are also modeled. Preliminary results of digital simulation indicate that a small integration step size is required to insure mathematical stability. For this reason, a dqo transformation of the generalized model is investigated and it is concluded that the presence of single-phase induction machines prevents further simplification of the system equations.
