Project 2

Due: Friday, October 10, 1997

The objective of this project is to evaluate the outage location methodology discussed in the class. All the programs you need are in a zip file A user's manual for the programs is also available. Note that these programs will execute only on a Unix machine.

Refer to Fig. 1 in paper "Location of outages in distribution systems based on statistical hypothese testing" by Rodrigo, Pahwa, and Boyer. The data for this system is given in a file You have to simulate all the three types of faults at specified locations (every student will be assigned different locations). Sample data files for faults between 850-816 are included in For this project consider that the protective device takes 0.04 sec to clear the fault.

  1. Run the simulations for a standard deviation of 0.02 sec, 0.04 sec, 0.06 sec, and 0.08 sec at a confidence level of 95%. Draw the plots for the three cases. Repeat it for a confidence level of 90%. Make sure to modify the t-statistic file for the confidence level selected.
  2. For your locations determine and . Find R for the non-central t-distribution using PROBT function in SAS. Compute the limiting value of standard deviation in noise for proper detection of the outage.
  3. Write a report explaining your results. Are you able to locate faults correctly? Do the theoretical results obtained in step 2 agree with the simulation results of step 1.

If you have any problem running these programs, send an email to Alex Shultz( and send a copy to me. Although this project does not have teams, I would like to encourage you to discuss it with your previously assigned partner.
