BROWSE_DETAIL_TAB_ABSTRACT

We present a simulation based study focusing on the application of a nonlinearcontrol technique to stabilize and control the terminal voltage and power angle of asmall synchronous generator driven by a steam turbine engine. The control techniqueis based on integrator back-stepping techniques which is an application of the secondmethod of Lyapunov to the states of a nonlinear dynamical system one-by-onerecursively. The theory is applied to two cases. The first one is the combined controlof power angle and terminal voltage of a single generator. The second one is thesynchronization of the power angles and terminal voltages of multiple generators(two or more). Upon obtaining a successful and stable generator control system for amain generator, we replicated the controller for another generator and feed thesecond generator’s reference inputs from the first generator’s outputs (power angleand terminal voltage of the main generator). The second generator has the samecontroller design. The same approach is applied to a three generator case. All thegenerators are assumed identical and same controller designs can be applied.Simulations are presented to verify the approaches developed in this research.Results showed that the control algorithms work satisfactorily in both singlegenerator and multiple generator cases. In the synchronization of multiple generators,the second and later generators have a very small delay.
