%X the aim of this work is to study the primary control system of a hydropower plant in isolated mode. the power plant is modeled by differential equations and results are compared to field data from an actual hydropower plant, presenting deviations lower than 1.0%. the study of primary control system is conducted in order to define useful sets of parameters for controllers. four controllers are studied: traditional, pi, pid and pi-pd. the performances are evaluated by stability criteria and a performance index. for the hydropower plant studied, the pi controller has the best performance.
