RESUMO

This work presents a new proposal to obtain the parameters of the regulator of a hydraulic turbine, looking for the goal to increase the operational control of a hydroelectric power plant. Among many existing methods, the Ziegler-Nichols shows itself adequate because in the determination of the parameters of the regulator simulations are carried out witch consider all the hydraulic behavior of the installation and the machine. From many simulations, to the adimensional rotation stabilization, varying the water time, the machine time and the rejection, it was realized that the coefficients used in the Ziegler-Nichols method weren t presenting good results in some situations, leaving evident the needy of an adaptation. The equations suggested in this work allow obtaining more adequate values to the proportional, integral and derivative constants, through the constant last proportional values and the last period, as already used in the Ziegler-Nichols method in function of the water time, the machine time and the power rejection
