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 OptionsVarious 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, 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
