Abstract :
The authors propose a generalized method to analyze the transient stability by using the three-phase bus admittance matrix algorithm for any network configuration. The method 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. Also presented is a novel, general systematic technique of studying transient stability of unbalanced distribution systems
