Integração de dispositivos eletrônicos inteligentes ao ambiente de simulação OPNET modeler

Abstract

The electric power system has undergone several changes over time. With the advance of digital communication and other technologies, the search for efficiency, interoperability and scalability has become a necessity in view of the electric system’s constant expansion. Based on this requirement, new solutions for the electric power system are proposed, for example, smart grids. This study examines the feasibility of using a hybrid system consisting of commercial intelligent electronic devices and a simulated communication network in order to verify the relevance of such approach in conducting studies in the smart grids context. The experiment was conducted by sending and receiving GOOSE messages between intelligent electronic devices in two distinct situations, entirely physical network and hybrid system. For results evaluation was applied the cross-correlation mathematical method. This method showed a great similarity between the two proposed approaches. In addition, the transfer time from GOOSE messages was within the IEC 61850 standard’s specifications. With this proposal validation is possible to apply the presented approach for the study of smart grids solutions, using a unique combination between physical devices and a simulated environment.
