Sažetak
The paper presents and compares two control structures for the excitation control of a synchronous generator. The first structure includes a neural network-based voltage controller. The proposed feedforward neural network integrates a voltage controller and a power system stabilizer. The modified error function used for the on-line training of neural networks by employing the backpropagation algorithm uses voltage reference and terminal voltage. The second structure includes a fuzzy logic controller with two control loops: a voltage control loop and a stabilization control loop with the function of a power system stabilizer. The proposed control algorithms as well as the conventional control structure are implemented in a digital control system and tested in a laboratory environment on a synchronous generator connected over a transmission line to an AC network. The experimental results described in this paper justify the use of advanced control structures based on neural networks and fuzzy logic in the excitation control system of a synchronous generator
