A wide range of publications which show several degrees of modeling machines and networks are available in the literature. The detail of representation for the network normally depends upon the problem being analyzed. For stability studies, most of these publications, if not all, consider the network to be balanced, and hence the mutual coupling between phases to be equal. This paper proposes a generalized method to analyze the transient stability by using the three-phase bus admittance matrix algorithm for any network configuration and which takes into account the unbalance created by large single-phase loads, untransposed feeders, conductor bundles and cables. Consequently, the effects of unsymmetrical shunt and/or series faults, as well as the addition or removal of single phase feeders can be simulated anywhere in the network. The paper does not introduce new models, but it presents a new general systematic technique of studying transient stability of unbalanced distribution systems.
