Dynamic Simulation of High-Power Machinery Systems.

Abstract : The purpose of this research was to develop accurate computationally efficient detailed and reduced-order computer models for typical high-power machinery systems being used or considered by the Navy. The detailed and reduced-order models of the example integrated power system (IPS) were developed. Example computer studies are given to illustrate the system performance during various large-disturbances including the operation of the pulsed power load. For purposes of validating the reduced-order modeling techniques, duplicate studies were performed using the detailed and reduced-order system simulations. These studies are presented along with an analytical description of the simulation of each component. The digital code is also provided to the Program Manager for use by the Navy and/or their contractors. It was also demonstrated that a vector controlled induction motor could cause negative-impedance system instability. A control was developed to eliminate this instability. This instability was predicted and eliminated by the computer models developed and then verified in hardware.
