Abstract

The safety and reliability of an electricity grid is defined by the quality of the power supplied to consumers. One of the important criteria for the stability of electrical networks is the frequency of the voltage produced. The aim of this paper is to develop digital corrector applied to the speed control system correcting on turbines to resolve the frequency variations problems in the output of the alternator caused by the imbalance between the active power produced by the turbo-generator and the power required by the load connected to the grid in the hydroelectric plants. First, a modeling of the turbine, the servo valve - servomotor assembly, the valve - flow function, the power chain as well as the alternator of the power station is presented. Then, three controllers (Proportional–Integral–Derivative, Internal Model Control and Robust Structure Theory) are studied, simulated and their performances were tested and compared in terms of instruction tracking and robustness. The simulations were realized by MATLAB/Simulink software. For the hydroelectric power plant studied, the RST controller has the best performance.
