A Digital Computer Program for the Automatic Determination of Dynamic Stability Limits

Dynamic stability limit under random disturbances

“…Various types of dc choppers such a s the Morgan circuit [ l J and the Jones circuit [2], have been used widely for motor speed control and other purposes. In these circuits, a dc thyristor is connected in series t o a power source and a load.…”

Effects of system nonlinearities on synchronous machine control

“…While various authors neglect saturation com pletely, others represent saturation only in the direct axis of the machine and a few represent saturation in both the direct and quadrature axes (14,25,36,57,72,89,90,91,94,108,109,119).…”

“…Another category of damping is the fictitious damping that needs to be included in a linear model of a power system in order that the model may be more stable or in order that the response of the linear model appears similar to that of the actual system (36,50,70).…”

“…Several authors have emphasized the need to represent some or all of these nonlinearities in stability and related studies (14,25,36,40,57,72,89,91,94,108,109,119,131,143).…”

Effects of system nonlinearities on synchronous machine control

“…At present there is no general agreement concerning representation of machine saturation. While various authors neglect saturation com pletely, others represent saturation only in the direct axis of the machine and a few represent saturation in both the direct and quadrature axes (14,25,36,57,72,89,90,91,94,108,109,119).…”
