Optimum Control of a Turbo-Generator Including an Exciter and Governor

A previous paper (1), has shown that a second order optimising algorithm can be applied to a simple model of a turbo-alternator to determine the optimum control inputs under transient conditions. This paper extends the application of this algorithm to a more detailed model including exciter and governor control loops. It is shown that suitable controls can be found to improve the transient performance of a large turbo-alternator, even in the presence of practical constraints on the control system.
