This paper presents the simulation study where the classic speed controller of a hydraulic power unit has been replaced with an unrestricted generalized predictive controller. The model of the power plant includes an excitation system, subsystem (speed controller, servo motor and turbine), load 1, load 2, Three-phase Transformer, External Grid and Fault. The electric three-phase fault has 0.1 seconds of duration. The results are compared with the responses of a conventional proportional integrative and derivative controller. The library of simulation developed by MathWorks “Power-Turbine”(Simulink) and for Matlab is used, also this research includes the steps for modify the library and so adapt it for our purposes.
