Geese: A traffic generator for performance and security evaluation of IEC 61850 networks

Automation systems for substations based on IEC 61850 simplify the design, installation, and maintenance of the system with a significant cost reduction. Indeed, the industry considers safety and reliability of real-time systems an essential factor. In this scenario, GOOSE messages used in IEC 61850 communication networks for protection, control, and automation of substation are very important. This paper addresses the development of a traffic generator to adequately evaluate and test system functionalities according to IEC 61850 traffic model. We design and implement Geese, a GOOSE message generator for performance and reliability of IEC 61850 networks evaluation. Generator results are also presented.
