Transcript Energy Monitoring System

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 labs
o
Time of day
o
Type of device
o
By room
• Provide educational display for visitors and students

Basic System Components
Design Options
 Various plug in systems
 D.I.Y option
 Power Logic BCM
 Owl Cm119
 TED 5000
TED System Components
 Current Transformers (CT)
 Measuring and Transmitting Unit (MTU)
 Gateway
TED System
 4 MTUs per gateway and 2 CTs per MTU
 Footprints software
 Accuracy within 2%
 Power Line Carrier (PLC)
 Measures RMS real power
 1 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,
 Can’t switch between
complex power, and real
power
 Graphically displays data
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

Panels in the Lab
• 2 phases and ground
• 3 phases and ground
• 180 degrees between each
• 120 degrees between each

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
