<P>PROBLEM TO BE SOLVED: To provide a method of analyzing a model of a balanced power distribution system which can avoid solution divergence generated by zero impedance branches or small impedance branches. <P>SOLUTION: A model of a balanced power distribution system is analyzed by transforming the model of the balanced distribution system with zero impedance branches to an equivalent model of the balanced power distribution system with non-zero impedance branches. Decoupled power mismatch equations with second orders are generated for each bus in the equivalent model. Power mismatches are determined using the bus power flow equations. The power mismatches are compared to a predetermined threshold. Then, for each bus, if the comparison is true, the power mismatch equations are solved iteratively until the comparison is false, to obtain a bus voltage magnitude correction and a bus phase angle correction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
