Investigation of transient stabilizing control effects on turbine-generator shaft torques
In this paper, the implementations of some specific transient stabilizing control means, exemplified by dynamic braking resistor, forced excitation and fast turbine valving, are investigated from the view-point of their potential effects on the torsional stresses in a turbine generator shaft system. For the purpose of this study, a state space digital simulation model of one machine infinite bus system is employed whereupon the interactions between the transient stabilizing control schemes, electrical and mechanical subsystems are well represented. The results of the phenomenon under investigation are presented and some pertinent conclusion drawn. In addition, the relative effects of the control means implementations on the turbine generator shaft torques are compared and their benefits from the standpoint of power system stability are discussed.
