Energy Monitoring System
By Demarcus Hamm
Advisor: Professor Cherrice Traver
Purpose
To advance Smart Grid concepts by analyzing data from an energy monitoring system.
Project Goals
Real time wireless energy monitoring system in ECE labs
Understand energy usage in ECE labso Time of dayo Type of deviceo By room
• Provide educational display for visitors and students

Approach
Design Requirements
Wireless Stores data by day and time Graphically display data Visible display More than one circuit Expandability
Basic System Components
Design Options Various plug in systemsD.I.Y optionPower Logic BCMOwl Cm119TED 5000
TED System Components Current Transformers (CT)Measuring and Transmitting Unit (MTU)Gateway
TED System
4 MTUs per gateway and 2 CTs per MTUFootprints softwareAccuracy within 2%Power Line Carrier (PLC)Measures RMS real power1 watt sensitivity
Final Design - Hardware
Display Requirements
ECE hall way Internet access Must be 2 inch depth or less No user interactions Stand by when no one is around
Display Choices
All in one computer Tablet PCs I-pad
Standby Mode Solution
Stand by when no one is present. PIR motion sensor Remote control
TED Footprints
Pros Cons Displays power factor,
complex power, and real power
Graphically displays data
Can’t switch between display modes automatically
not very fine detail No way to tell MTUs
apart or values without user interaction
Software
“It’s Electric” modified Switches between displaying by
minute, hour, day, and month Can be viewed off the Union Network Faster than Footprints and has finer
details

Electrical System Complication
Home Panel Panels in the Lab
• 2 phases and ground• 180 degrees between
each phase
• 3 phases and ground• 120 degrees between
each phase
MTU Compensation
TED5000 support forum advice. Cannot connect between phases.
Wait for 3 phase MTU
Future Work
Software improvements Add additional sensors to the set up Change MTUs for 3 phase Incorporate the circuits in the N100
panel
