| Summary: | In the 21st Century, where technology is heavily dependent on the electricity to function
and served its purposes, we tend to consume a massive amount of electricity knowing
that natural gases are replenishing faster than it is being replenished. As a result, this
the project aims to develop a load monitoring system for residential units to better monitor
their load consumption and aims to reduce the end-user electrical consumptions.
Non-Intrusive Load Monitoring (NILM) is a technic whereby using only one sensor
measuring devices to capture the total load consumption and identify each load
appliances among the total energy power. In this way, it will provide the user on how
much each load contributes to their power consumption daily, and thus encourage them
to monitor their load properly.
NILM system mainly has 2 components in this project, mainly the hardware design and
the software approach. Electrical Data is being captured by the Yokogawa Power Meter,
the information is then transmitted to the host machines via RS-232 Bluetooth
Connection. In the host machine, both LabVIEW and MATLAB are used for designing
the algorithm. Steady-state analysis is used in identifying the load type. Upon exceeding
the power limitation set by the user, both a warning light will be issued on the Graphic
User Interface (GUI) and an E-Mail notification to alert the user the power exceeds and
the appliances contributing to the exceeding of power limit.
Lastly, a GUI is developed to display all information required to the user based on a
real-time scenario. The result of this project is to encourage the usage of this monitoring
system to monitor their daily energy consumption, and thus cut-off unnecessary electrical
appliances. |
