PC-SHORT is a program that analyzes the effect of different types of faults on a portion of an electric power transmission system of subtransmission system. The program is highly interactive and allows an engineer to construct easily a schematic of the transmission system, to modify the system (by adding or deleting buses, generators, transformers and transmission lines), to change the type and location of the fault, and to view the fault induced voltages at any bus or currents in any system component.

Four type of faults are considered by PC-SHORT: (1) a three phase fault, (2) a line-to-line fault, (3) a single line-to-ground fault, and (4) a double line to ground fault. The fault may be placed at any bus in the system. Once the system is defined and the type and location of the fault is specified, PC-SHORT calculates the resulting voltages at every bus and the currents in every component.

PC-SHORT is intended to be a tool for performing rapid analyses on a portion of a transmission system which is of concern (perhaps, because of some accident condition or unforeseen alteration). Consequently, PC-SHORT has many features to aid the analyst in quickly setting up the system and determining the effect of faults on the system. Some of these features are

While PC-SHORT can be learned without recourse to external documentation, a manual is available. (A User's Manual for PC-SHORT, Engineering Experiment Station Report 205, Kansas State University, Manhattan, KS 66506.)

The computational technique employed by PC-SHORT is described in the paper, "Analysis of Faulted Power Systems Using the Householder's Formulas," by A. Pahwa, A.A. Chavez and J.K. Shultis, Proc. of the Twentieth North American Power Symposium, pp 89-98, Purdue Univ., West Lafayette, IN Sept. 26-27, 1988.
