- Slide 3
- PROJECT GOAL 3 Automate the process of receiving information
about a power line fault from relays and displaying the information
and location on a map to assist in a quicker response time in
repairing the fault.
- Slide 4
- BACKGROUND INFORMATION 4 ArcGIS GIS: Geographic Information
System - provides a framework for gathering and organizing spatial
data and related information so that it can be displayed and
analyzed Used by Idaho Power to display complete distribution
system along with attributes about the individual pieces of that
system; i.e. Power pole, substations, transmission lines, capacitor
banks, etc.
- Slide 5
- BACKGROUND INFORMATION (CONT.) 5 SELocator Developed by members
of Schweitzer Engineering Laboratories Provided to us for use in
this project Evaluates Event Files from the relays on the power
lines and determines the location of the fault by telling the
distance down the line from the relays that the fault occurred.
(Usually uses 2 relays for calculations) Accuracy that is expected
from this program is to show the fault at the nearest structure to
the location of the fault.
- Slide 6
- BACKGROUND INFORMATION (CONT.) 6 The relays used on
transmission lines create event reports when a power line fault
occurs The type of fault and the location are necessary to send
crew out to repair Previously users had to call the relays in order
to get the event files from them and begin finding the location of
the fault The method used previously would highlight the
transmission line that the fault occurred out to an estimated
distance where the fault was believed to occur Problems with
previous method: Not automated, less accurate, doesnt just show the
location of the fault, takes more time to get all information
needed
- Slide 7
- PROJECT CONTEXT 7 SELocator will be used to find the location
information of the fault The program to be created will get the
information and display an accurate estimate of the location of the
fault on a map for the users to see in a quick manner Benefits:
Information will automatically be collected and displayed, will get
all necessary information quickly, more accurate results, repair
crews will have a better response time

- NEEDS AND SPECIFICATIONS 9 The system to be designed must:
Automatically read output file from SELocator with fault
information Take information from output file, parse the
information and transfer to mapping program with location of fault
shown Display fault symbol on map at nearest structure to the
location of fault found from SELocator. Should use provided trace
web service code used before to take the information from event
files and determine the latitude and longitude of fault.
- Slide 10
- NEEDS AND SPECIFICATIONS (CONT.) 10 Ability for user to choose
default time out of fault symbol on map along with the ability for
user to easily remove fault symbol manually when repaired Should
show fault location within 1 minute of when fault was detected by
relays

- PROJECT SCHEDULE (CONT.) 12 Goal for this semester is to
complete a usable demo version of the program and have it running
for 1 set of transmission lines Goal for next semester will be to
begin to apply the program to more of the lines in the system
