Abstract :
The author presents an advanced simulator with the following features: the transmission line on which switching operations are performed can be untransposed, while the rest of the system is still represented as symmetrical; and the effect of induction motor dynamics can be represented by the time domain simulation of varying speed, slip and machine impedance. The simulator is designed to permit interactive experimentation for examining diverse phenomena in balanced or unbalanced steady state, produced by any sequence of switching, such as fault inception, clearing, temporary overvoltages, effects of compensation, motor starting, and so on. It can be used for educational purposes and for planning and design. Illustrative examples are given for both line and fault switching and for induction motor dynamics.
