Using the Non-Intrusive Load Monitor for Shipboard Supervisory Control

Field studies have demonstrated that it is possible to evaluate the state of many shipboard systems by analyzing the power drawn by electromechanical actuators. One device that can perform such an analysis is the non-intrusive load monitor (NILM). This paper investigates the use of the NILM as a supervisory control system in the engineering plant of gas-turbine-powered vessel. Field tests conducted at the Navy´s DDG-51 Land-Based Engineering Site (LBES) demonstrate that the NILM can potentially reduce overall sensor count if used in a supervisory control system.
