SCHEDULECONCLUSIONPROJECT GOAL3Automate 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.BACKGROUND INFORMATION4ArcGIS 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.
BACKGROUND INFORMATION (CONT.)5SELocator Developed by members of
Schweitzer Engineering LaboratoriesProvided to us for use in this
projectEvaluates 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.BACKGROUND INFORMATION (CONT.)6The 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 repairPreviously users had to call the relays in order
to get the event files from them and begin finding the location of
the faultThe method used previously would highlight the
transmission line that the fault occurred out to an estimated
distance where the fault was believed to occurProblems with
previous method: Not automated, less accurate, doesnt just show the
location of the fault, takes more time to get all information
neededPROJECT CONTEXT7SELocator will be used to find the location
information of the faultThe 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 mannerBenefits:
Information will automatically be collected and displayed, will get
all necessary information quickly, more accurate results, repair
crews will have a better response time8
NEEDS AND SPECIFICATIONS9The system to be designed
must:Automatically read output file from SELocator with fault
informationTake information from output file, parse the information
and transfer to mapping program with location of fault shownDisplay
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.
NEEDS AND SPECIFICATIONS (CONT.)10Ability 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 repairedShould
show fault location within 1 minute of when fault was detected by
relays
DESIGN FLOW CHART11PROJECT SCHEDULE (CONT.)12Goal for this
semester is to complete a usable demo version of the program and
have it running for 1 set of transmission linesGoal for next
semester will be to begin to apply the program to more of the lines
in the system
