A robust artificial neural network based speed/voltage regulator for synchronous generators

The paper presents a novel coordinated excitation/governor artificial neural network (ANN) based controller for AC synchronous generators. The proposed ANN based controller replaces the full global action of the voltage regulator, power system stabilizer, and speed governor controls. The detailed design methodology of the ANN based controller, the training, and validation results based on the performance of the best benchmark conventional excitation and speed controls are presented in the paper. The dynamic simulation results and study of the performance of ANN based coordinated control scheme in comparison with the conventional excitation/governor action are also presented in the paper
