Graphical modeling of shipboard electric power distribution systems

Description

With the increasing application of power electronics to shipboard electric power systems, there is a need for studying power systems in an object- oriented, graphical environment in order to examine the interrelations of the various system components. This thesis presents a method of analyzing shipboard electric power systems in a graphical environment. The simulation method used allows for real-time observation of the various power system measurements of interest. The machine equations, including those for voltage, torque, and rotor angle are developed which permit analyzing the machine in any chosen reference frame depending on the study being undertaken. Regulars for both speed and field voltage are developed and the stability of the speed regulator is examined. A means of modeling a load for a synchronous generator is then shown which accurately interrelates the loading of the generator and the frequency and voltage output of the machine. This load is then connected to the synchronous generator and two different scenarios are examined including a fifty percent load change and a fault study. Graphs showing the output of these studies are presented.
