Abstract
An electromagnetic transient analysis program using Dommel's method has been implemented on a 16-bit microcomputer running under MS-DOS operating system. The program has been mainly tailored for classroom teaching purposes,however,by proper modelling the program can be used to study transient phenomena in practical systems. The program is command driven and is resilient to data errors. The program provides tabular display, printer plots and high resolution graphic plots as output. The interactive feature allows the user to change the network parameters and observe the consequent system response. The program can be used for a range of problems, such as, transient response of electrical networks with discrete elements, switching surge calculations, effects of breaker closing resistance and shunt reactor, TRV calculations and faulted system transients. Any general configuration of resistances, inductances, capacitors and transmission (distributed parameter) lines with both current and voltage sources can be studied. A three-phase system is modelled using the corresponding positive sequence equivalent network. This paper describes the salient features of the program and its usage, through a range of examples. The program will assist an engineer or student to understand transient phenomena in power systems conceptually and focus attention on power system modelling using the most appropriate network model for transient analysis.
