Validação do protocolo rstp em sistemas de automação de subestação para aplicação com goose

Abstract

Industrial Substation Automation Systems are already becoming common and widely used. With the advent of this modality the Ethernet networks had to adapt to the levels of exigency required by these systems. Automation equipment has become more robust and redundant topologies are more present. The RSTP protocol was introduced to guarantee the absence of loops in these topologies and reduce the convergence and restructuring times of the active network in case of failures. This paper presents analysis of the performance of the RSTP protocol in an Ethernet network implemented in a project of a digital substation, as well as the observation of the recomposition time for the GOOSE protocol application.
