Abstract
This article presents an approach to the mathematical modeling of the turbine-generator set considering its application in hydroelectric power systems. In contrast to other publications that typically handle these components separately, an integrated model description was chosen to represent the dynamics of the entire system. Due to the nonlinearities present in the equations representing the dynamics of physical variables, the model was linearized. The Linear Quadratic Regulator and Minimal Energy methods were used to exemplify the application of this model in designing control strategies. Simulation results were obtained, demonstrating that the behavior of the linearized model closely resembles the nonlinear model for small signals and shows an improvement in response to a three-phase fault for the closed-loop system.
