The thesis explores the use of the Non-intrusive Load Monitor (NILM) in Condition Based Maintenance (CBM) applications on US Navy ships as part of the Office of Naval Research Electric Ship Integration (ESI) Initiative. The NILM is a device that measures an electrical component's performance by applying a single voltage and current transducer to a ship's existing power distribution system. The NILM was originally developed to monitor electrical power usage in buildings where it was noticed that it could disaggregate and report the operation of individual loads when many loads were present. The limits of this capability are explored by employing a signal processing script in MATLAB using component data gathered on the USCGC SENECA (WMEC-906). The plausibility of using a few NILMs to provide machinery monitoring information for an entire engineering space, and the resulting opportunity to reduce sensor growth on future Navy ships is explored. Then efforts to monitor naval propulsion plant machinery with the NILM are discussed. Two NILMs were constructed and installed on selected individual components at the Naval Surface Warfare Center Philadelphia DDG-51 Land Based Engineering Site (LBES).; (cont.) Monitoring of the Fuel Oil and Low Pressure Air Service Systems was conducted during a week long certification of the pre-commissioning crew of the USS BAINBRIDGE (DDG-96). Data collected was then used to explore the use of the NILM as a diagnostic device for shipboard systems through the evaluation of mechanical transients in the Fuel Oil system and a test leak inserted into the Low Pressure Air System.

This research quantifies the voltage distortion over the broad range of operating conditions experienced by a Naval warship. A steady state model of an Integrated Power System (IPS) was developed in a commercially available power system simulation tool. The system chosen for this study was a three-phase, 4160 VAC, 80 MW power system with a 450 VAC bus to supply traditional ship service loads. Sensitive loads, such as combat systems equipment, are isolated from the harmonic content of the 450 volt bus via solid state inverters. Power generation for this system included two 30 MW and two 10 MW generators. The sizing of these generators was based on operating configurations that would result in the best fuel efficiency under the most common loading conditions. Model components were simulated and compared to data recorded for the U.S. Navy's Full Scale Advanced Development (FSAD) test system for the IPS at the Philadelphia Land Based Engineering Site (LBES). The propulsion motor used in the simulations was developed based on the advanced induction motor installed at LBES.; (cont.) Various loading conditions, including battle, cruise and anchor were simulated for both 10⁰F and 90⁰F ambient design conditions and with propulsion loads ranging from 0% to 100%. Numerous system configuration changes were implemented to determine their impact on system harmonics. These included operating the propulsion converter front end rectifiers in both controlled (varying commutation angle) and uncontrolled (diode bridge) configurations; implementation of both twelve and six pulse rectification; and installation of a tuned passive 5th harmonic filter. The simulation results are compared to both IEEE Std 519-1992 and Mil-Std 1399.; by Edward G. West.; Thesis (Nav. E.)--Massachusetts Institute of Technology...
