Neural network based current controller for HVDC transmission systems

The paper presents a neural network (NM) based current controller for a rectifier in a two-terminal HVDC back-to-back tie. This controller adapts its gain parameters to provide better or similar recovery dynamics when compared to the more traditional PI current controller. Comparisons between the proposed NN and traditional PI controller responses are provided by means of results obtained from digital simulations made with the EMTDC simulation package.<
