A simple mechanical analogue for solving certain power-system stability problems

This simple device, useful in solving many system stability problems, gives a clear physical picture of the performance of a synchronous machine under steady-state or transient conditions. The model permits the derivation of predetermined swing curves similar to those of Summers and McClure and offers a quick method of finding critical switching and reclosing times. Probably damping forces like effects of governors and regulators can be simulated.
