Abstract

For pt.I see ibid., vol.3, no.1, p.85-90 (1988). The essential dynamics for a hydrogenerator supplying a large grid may be represented by two control loops: the first for power and the second for speed. Previously, the authors developed a governor design intended to neutralize the speed loop´s destabilizing effects while tuning for improved load tracking. The practical implementation of such a controller by computer is considered. An approximate system is used to develop analytical expressions for the control parameters. These parameters are functions of load level throughout the operating range and may be computed in real time. The effectiveness of the approximate-system-derived control is verified by simulation. Computed transients are indistinguishable from transients for the optimally tuned control
