Reconfiguration in shipboard power systems

A shipboard power system is self contained, tightly coupled, and small enough to allow nearly real time state estimation, given the right equivalent circuit representations. Redirecting power flow is the preeminent task of reconfiguration. This redirection should be accomplished in less than two cycles, while never compromising system stability or power delivery to critical loads. These performance objectives can be achieved using equivalent impedance system representations and various optimization procedures, as demonstrated by simulation. Additional issues are addressed concerning proper realization of a reconfigurable power system by incorporating gas turbine status, and due consideration for stable and safe transition between different power system states.
