A framework for non-intrusive load monitoring and diagnostics

Abstract

The widespread use of electrical and electromechanical systems places increasing demands on monitoring and diagnostic techniques. The non-intrusive load monitor (NILM) provides a low-cost, low-maintenance way to perform this monitoring and diagnostics from a centralized location. This work critically evaluates the current state of the NILM hardware and software in order to develop new techniques and a new hardware and software framework in which to better apply the NILM to real-world systems. New diagnostic indicators are developed on the USCGC SENECA using an improved hardware and software platform. A database-driven framework with the flexibility to create and implement these and future diagnostic indicators is presented.
