Energy Monitoring

Abstract
This project combines research of the Smart Grid system and energy monitoring systems. The project will use an
energy monitoring system to simulate smart meters that will be used in the Smart Grid system. We will do this by
using an energy monitoring system to measure the energy consumption in the electrical engineering labs. The
analysis of this data will provide us information that could lead to energy savings by making us more aware of
wasteful energy use or helping to create an energy management system.
Display Requirements
Goals
Design Requirements
• Provide educational display for students, faculty, and
visitors to raise awareness of energy consumption and
Smart Grid ideas.
• Gain information that could lead to future management
systems which would lead to energy savings.
• Create a system that could be expanded for greater
benefits.
In order for us to meet our goals the system must
meet certain design requirements. The design must:
• Use wireless technology
• Store data
• Graphically display data
• Contain a separate visible display
• Monitor more than one circuit in a panel
• Be expandable
The display for the project will be in the ECE hall
ways in a clear display case; therefore the following
requirements must be met:
• Must have internet access
• Must be 2 inches depth or less
• No user interactions required
• Stand by when no one is around it
To address the stand by mode we looked into passive
infrared sensors that would turn the circuit off when
no one is present and display options that have
remotes to switch them into standby.

The MTU has errors when working with 3 phase
systems. The power factor calculation is off because
of this and so the accuracy of the RMS real power
suffers. To compensate for this we can connect the
MTUs and CTs to one phase. This will take away our
ability to use two different phases with one MTU. The
other option is to wait and replace the MTUs when the
3 phase model is released in June.

The table above shows the energy consumption in the ECE labs by load type
and by room. The odd rooms and room 108 were not included because since
these rooms are small and not as heavily used as others. This table was
made to find out which type of load and which rooms used the most energy.
After doing this our hypothesis was that since this was the maximum power
consumption, the lights and the computers would be the highest because they
are in use more than the other load types. Out of the rooms shown rooms 100
and 102 are the most commonly used.
The design will use the TED 5002-G system which consist of two measuring
and transmitting units (MTUs), four current transformers, and one gateway.
The current transformers will clip on to four circuits and the panel and
measure the current. The MTUs will sample the voltage and perform
calculations to get real RMS power then send this information through the
circuits to an outlet connected to the gateway. The gateway will then store
the data and send it through the network to the visual display.

Future Work
ECE Lab Connection Diagram
• Software improvements
• Add additional sensors to the set up
• Change MTUs for 3 phase
• Incorporate the circuits in the N100 panel

This diagram shows which panel the outlets and lights in each
ECE lab are connected to. The number beside the lines
connected to the outlets show how many circuits on the panel
are connected to outlets in the room. The lights in rooms 100,
102, 104, and 106 are connected to 2 circuits. The other lights
are connected to only one.
The figure above shows the communication layout in the project. The
software is in circles and the hardware is in squares. The TED
Footprints software comes with the TED system to display data. It is
stored in the gateway and communicated to the Union College network.
The It’s Electric software is a modified third party software we are using
to display our data. It is run on antipasto and can be viewed from the
network. The third party software was used because Footprints can not
switch displaying minute, hour, and monthly data automatically. You
also cannot tell which MTU you are observing without user interactions.
