1. Energy Monitoring System By Demarcus Hamm Advisor: Professor Cherrice Traver

2. Purpose  To advance Smart Grid concepts by analyzing data from an energy monitoring system.

3. 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

5. Approach

6. Design Requirements Wireless Stores data by day and time Graphically display data Visible display More than one circuit Expandability

7. Basic System Components

8. Design Options  Various plug in systems  D.I.Y option  Power Logic BCM  Owl Cm119  TED 5000

9. TED System Components  Current Transformers (CT)  Measuring and Transmitting Unit (MTU)  Gateway

10. 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

11. Final Design - Hardware

12. Display Requirements  ECE hall way  Internet access  Must be 2 inch depth or less  No user interactions  Stand by when no one is around

13. Display Choices  All in one computer  Tablet PCs  I-pad

14. Standby Mode Solution  Stand by when no one is present.  PIR motion sensor  Remote control

15. TED Footprints ProsCons  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

16. 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

17. Communication Diagram HTML Raw Data

18. Electrical System Complication Home PanelPanels in the Lab 2 phases and ground 180 degrees between each phase 3 phases and ground 120 degrees between each phase

19. MTU Compensation  TED5000 support forum advice.  Cannot connect between phases.  Wait for 3 phase MTU

20. Future Work  Software improvements  Add additional sensors to the set up  Change MTUs for 3 phase  Incorporate the circuits in the N100 panel
