Abstract :
A partitioning scheme for transient simulation of shipboard power systems (SPS) is presented. Using diakoptics, the piecewise transient solution to a ungrounded AC-radial (3phi) ring-bus system is found. Cable tie-lines (floating pi-segments) on the SPS ring are converted to hexagon equivalents by discretization and decoupled via source-transportation, diakoptics, and exploiting mutual-susceptance links. Transient simulation results from circuit simulation (as a whole) and via diakoptics (piecewise) are compared and discussed.
