Multivariable minimum variance self-tuning control of the exciter voltage and turbine speed of an isolated a-c turbogenerator system connected to a large-scale power network is considered. Simulation studies, employing a high-order non-linear representative system model are reported, with emphasis on rigorous assessment of performance within an operational context. Three-phase faults, with and without permanent line-switching, dynamic and transient stability, are amongst problems addressed, and comparison with conventional control philosophies is made. Convergence of the self-tuning algorithm under a wide range of operating conditions is demonstrated, and results indicate that a self-tuning controller, based on minimal advance plant knowledge, provides a viable, robust alternative to conventional schemes within the power system environment.
