Framework of non-intrusive load monitoring for shipboard environments

A Non-Intrusive Load Monitor (NILM) measures power at a central point in an electrical network in order to provide real-time energy management and equipment diagnostics. Results are presented from NILM systems installed aboard two US Coast Guard ships. The collected data is used for fault diagnostics and condition-based monitoring of mission-critical systems. A NILM system requires a complex software pipeline that captures and preprocesses data, accurately disaggregates load events from the aggregate power stream, analyzes the equipment for potential faults, and presents useful information to end-users in real-time. This thesis presents a framework for load identification, as well as an analytical and graphical platform that provides diagnostic information to operators in real-time about the health of electromechanical systems.
