Adaptivna distantna zaštita dvostrukog prijenosnog voda primjenom Kohonenove neuronske mreže

This paper elaborates adaptive distance protection of a double-circuit transmission lines. In the first place it is discussed distance protection problem caused by mutual coupling between conductors, it is also discussed secondary problem, influence of the fault resistance. The paper presents adaptive model which is solution for the mentioned problems. Adaptive model is based on neural network - self-organized Kohonen network which is the most appropriate model for this type of problem. In the paper it is given short review of the Kohonen network. The developed model was tested on the double-circuit line Žerjavinec-Héviz.
