Integrated control of a nonlinear turboalternator model under fault conditions

Effects of system nonlinearities on synchronous machine control

“…The Increasing complexity, both in design and operations, of the present day power systems requires more detailed system models and one of the many ways of providing the necessary detail is to include, in one form or another, the system nonlinearities (57,89,91,94,104,108,109,116,119,136,142).…”

“…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).…”

“…Where system stability and control problems are concerned, the literature contains adequate evidence showing that significant differences exist between the results obtained when load nonlinearities are neglected and when they are included in the studies (1,18,42,89,91,132). Several methods of representing loads have been proposed (11,60,94,109).…”

“…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).…”
