New Techniques for the Calculation of Dynamic Stability

A 100-machine transient stability program has been developed which represents the effects of machines much more completely than has been available previously. Both d-and q-axis quantities are fully represented and saturation effects in both axes are incorporated. The speed-governing and voltage-regulating systems available are extensive and complete, thus allowing a very close approximation to any physical system. Facilities for nonlinear loads and induction motor transients are also included.
