Self adaptive protection systems

The work propose the modeling and the conceiving of a conduction system for the cross differential protection of the parallel lines, by using the formalism of the Petri networks. By these models the facilities provided by the use of the Petri networks are justified as far as the analysis of the protection operating dynamism is concerned and also the possibility of using the model in the effective conduction of the same by means of a proper software. For the protection modeling and conduction a non-autonomous Petri network of RP Pr T-temp is used.
