Determination of the Dynamic Response of Electrical Systems by Means of a Digital Program

All the solutions for the determination of the stability of an electrical network by means of digital computers contain some approximation, because of the complexity of the system simulation. The simplifications adopted in the majority of these programs are not always justified and, therefore, the confidence in the results is not always well established. The choices made in making a new program are discussed. They are related to the network component simulation, to the numerical process, and to the program specifications.
