This work presents a study based on the speed and power control of a large hydroelectric power plant through the mathematical modeling of the real system and the use of computational simulations to validate the field data and evaluate the response of the control systems studied over different scenarios. A reference analysis was necessary to provide basic concepts about the system studied as well as topics related to theories of control, modeling and controller designing. Specific data from the presented case studied were applied to the mathematical modeling. In doing so, it was possible to validate the calculated models by using computational simulations. This validation was performed by comparing simulation results with field testing records obtained from the power plant studied. More computational simulations were executed using validated and adjusted mathematical models to evaluate operational performance of the speed governor system. Additionally, some proposals of adjustments were made by applying known controller tuning methods in order to improve the equipment performance.
