Self tuning control for turbogenerators in multimachine power systems

Abstract

The application of self-tuning automatic voltage regulators to generators in a multi-machine power system is described. The regulators have supervision schemes which ensure effective operation under all conditions. The performance of the regulator has been evaluated using a detailed multi-machine power system model. Results are presented which show that the self-tuning regulator provides good control in a multi-machine environment, when operating in conjunction with conventional regulators on other generators. A comparison with a conventional regulator shows that the self-tuner gives better performance.
