Abstract

"For a given power system of no more than 100 buses and 400 line ends (source lines have one line end, radial lines have one line end and regular lines have two) a digital computer program is presented which determines the short circuit currents needed to implement a protective relaying design, The program uses the ZBUS method of analysis and calculates the currents at all buses, searches for the maximum and minimum values of the current contributed by the lines connected to the faulted bus under normal conditions (all lines in) and under single and double line outages. Maximum and minimum ratios of bus currents are also calculated and lines whose outage cause the limiting values of currents or ratio of currents are identified.

A sample problem is presented, and results are briefly discussed to convey a better understanding of the program capabilities and limitations"-- Abstract, p. ii
