Introduction
Non-intrusive load monitoring (NILM) or non-intrusive appliance and load monitoring (NIALM) is a method of monitoring the load at a single monitoring point in a facility:
The process of using load characteristics to provide estimated electricity usage (such as heating, cooling, etc: by usage type, or microwave ovens, etc: by appliance type):
Non-intrusive load monitoring systems can be used to investigate the specific use of electrical energy in residential, building or industrial areas (see Figure 1):
Figure 1 Schematic diagram of non-intrusive load monitoring principle
At present, non-intrusive load monitoring systems are basically used in AC distribution networks, but DC distribution networks are not excluded:
Non-Intrusive Load Monitoring (NILM)
Sensor device for system
1 Scope
This document attempts to provide the latest state of the art in non-intrusive load monitoring (NILM) systems:
Classification of NILM sensing devices:
In the future, we may consider the NILM decomposition algorithm and the classification of NILM systems, as well as the performance indicators of NILM systems:
NILM systems generate an estimated breakdown of electricity usage: Accurate measurement and analysis of energy consumption and/or other electrical parameters is required
When used for monitoring electrical facilities, use a standard measuring device (such as a power measurement and monitoring device (PMD), power quality monitoring device (PQM) or a power quality monitoring device (PQM)):
equipment (PQI) or instrument]:
Note: In addition to safety and structural requirements, standardized measuring devices guarantee accuracy within the specified range and are not affected by influencing quantities (such as temperature, frequency deviation, etc:)
